ZOTAC GTX 760 SLI Review

The ZOTAC GTX 760 offers great performance for mid-range budgets. We pair this card up with another for some SLI GTX 760 action…

Product on Review: GeForce GTX 760 2GB GDDR5
Manufacturer and Sponsor: ZOTAC
Price: £209 R.R.P

Our first NVIDIA GTX760 review comes courtesy of ZOTAC. Their interpretation of the NVIDIA reference design is identical however knowing ZOTAC very well, you can be assured there will be overclocked and custom cooled AMP! editions hitting the shelves very soon. For now though, we take a look at what is NVIDIA’s reference design and pair this card up with another GTX 760 to see how SLI compares because cards at this level attract the type of person who demands performance yet requires that performance at a reasonable cost.

SLI, you see, is not just for those who have more money than sense. It is now so good at scaling that even the most miserly of gamers can see the benefits of pairing a couple of mid range cards together if one is looking for extreme performance but at a reduced cost. For this the GTX 760 could well be the card of choice. It has a trimmed GK104 core; the same core used on the scorchingly fast GTX 680 and GTX 770 GPUs so we know already that it certainly has the power yet, at just £209 (R.R.P), it has a price that undercuts the competition and by a fair margin.

NVIDIA are pitching this card against the mighty AMD HD7950 and indeed the GTX 760 will be the card which replaces the GTX660Ti so it will need to be something special. NVIDIA seem to have gotten the price right and have made a solid choice by arming the latest GPU with a GK104 core however I do worry that the 2GB of GDDR5, even with a 256-bit memory controller may prove to be the deciding factor.

With this in mind I think we should take a closer look at the specifications and features of the ZOTAC GTX 760…

About ZOTAC

Established in 2006, ZOTAC is the world’s largest and most innovative manufacturer of graphics cards, mini-ITX motherboards and mini-PCs. ZOTAC system components, and mini-PCs can be found in all continents around the globe.

Derived from the terms “zone,” for being distinct in the PC components and systems business, and “tact,” for our superior skill, experience, quality and manufacturing capabilities. Combined, “ZOTAC,” represents technological strength and experience blended with a fresh approach on the industry’s ever-changing needs.

The ZOTAC commitment to our customers is to bring the latest products and technologies to the market with superior value and quality. Needless to say, ZOTAC is the right choice for high-quality and high-performance components with exceptional value.

Specification

Based on the same GK104 found on the GTX680, the GTX760 contains 1152 CUDA cores at a clockspeed of 980Mhz. This clockspeed coupled with GPU Boost 2.0 will allow the card to typically boost overclock to 1033MHz. The GTX760 also comes equipped with 2GB of GDDR5 and features four 64-bit memory controllers (256-bit). This memory is clocked to 6008Mhz (effective) however if previous results are anything to go by, this tasty memory will overclock much further than reference speeds so expect to see some good improvements in our overclocking section.

Above is an 8 Core Kepler. NVIDIA tell us that 2 of the cores would be disabled either by disabling 1 graphics processing cluster all together or just one core from two of the clusters.

Kepler Core
The GTX760 is equipped with a GK104 core is fabricated on the 28nm process with every component was designed with power efficiency in mind to ensure the GPU gave the best performance-per-watt possible.

While the 28nm manufacturing process holds the bulk of the power saving features, the way the new architecture works is also key to furthering Kepler’s power reduction. SMX, an evolution of the SM from Fermi is NVIDIA’s new streaming multiprocessor:

Each SMX runs at the graphics clock speed rather than 2x that speed as previously but because the GK104 has 1536 CUDA cores (8xSMX), over Fermi’s (GF110) 512 CUDA cores (16xSM), Kepler allows the GTX760 to operate at twice the performance per watt measurement compared to the GTX560.

To feed each SMX, each unit has four warp schedulers, each capable of firing off two instructions per warp, every clock. With a redesigned scheduling function, the GTX760 is a lot less complex and much more streamlined allowing the compiler to determine which instructions will be issued and can provide this information direct to the hardware block rather than going around the houses using Multi-port decode and a register scoreboard along with the dependency check before the information gets issued. This method is both quicker and more importantly, more power efficient.

Perhaps the biggest change from Fermi to Kepler was the omission of the old Shader Clock. The shader clock was getting tired as it was part of the old Tesla architecture which was implemented as an area optimisation. Because of the way Kepler executes instructions at a much more streamlined manner and at a higher clock rate, fewer copies of the execution unit need be made.

Another improvement over Fermi with the introduction of SMX is the redesigned Polymorph engine (2.0). The Polymorph engine takes card of the tessellation workload of the GTX770. The design of the Polymorph engine is to ensure that the tessellation we see on screen has little (as possible) impact on the rendering performance. What you may find bizarre though is that NVIDIA have cut the Polymorph engine count in half to 8 from Fermi’s 16 yet claim it is almost twice as quick. This is thanks to the improved core an memory clockpeed.

With both a higher core clockspeed based on older (but still very fast) GK104 core and of course that blisteringly fast memory, the GTX760 looks set to replace not only the GTX660Ti, but also offer a viable, yet cheaper alternative to the HD7950 GPU.

GPU Boost 2.0

GPU Boost caused a bit of a stir when it was first introduced because it did away with the traditional ‘absolute’ method of dictating MHz. Rather it worked by overclocking the card by different means. To achieve an overclock using GPU Boost, one increased the MHz and Voltage as per usual however the card would then ‘Boost’ when placed under load. So rather than having a fixed clockpseed, the GPU adjusts the clockspeed depending on load, ensuring the power is there when you need it rather than it being full on all of the time, thus saving power consumption and heat production by having the card overclock dynamically.

GPU Boost 2.0 is an evolution of this idea. The techs at NVIDIA have determined that GPU power was unnecessarily limiting performance when GPU temperatures was low. Instead of boosting GPU performance based on a power target, it is now based upon temperature with this temperature threshold being 80 degrees Celsius.

Because the boosting is now determined by temperature, noise levels are also reduced as NVIDIA claim the GTX cards deliver a better acoustic profile.

So to summarise, overclocking the card using GPU boost 2.0 means adjusting the temperature threshold, for example from 80c to 85c. The GPU clockspeed will then gradually increase until it reaches this new temperature and will be dynamically adjusted on-the-fly to stay within this threshold. Because of this it is much more difficult to claim one GPU is faster than another without having both working under precisely the same operating conditions.

It therefore should go without saying (but we will say it anyway) that the colder your card runs, the faster it should theoretically operate as a colder card allows overvolting and thus even higher clockspeeds.

GPU Boost 2.0 also features overvoltage control. NVIDIA make no bones that enabling this function will damage the long term operability of the graphics card and as with AMD’s overdrive, you have to acknowledge this fact before you can unlock the cards voltage control. We applaud NVIDIA for this because they have acknowledged that enthusiasts, like us here at Vortez, like to push hardware to the max and without voltage control, the whole process becomes so much more uninteresting and much more difficult.

So, because GTX760’s boost clock and voltage level are now tied to the GPU’s temperature, the voltage can be dialled higher which in turn will allow the GPU to attain higher clockspeed values. Obviously, increasingly board voltage, as with most other products, will gradually degrade the GPU through electron migration causing a premature death of the GPU. Voltage support will be offered on a board partner by partner basis however, we would be extremely surprised if it wasn’t enabled in every GTX760’s VBIOS.

We will see how GPU Boost 2.0 performs in our overclocking section later in the review.

GeForce Experience

GeForce Experience is a new application from NVIDIA that optimizes your PC in two key ways. First, it maximizes your game performance and game compatibility by automatically downloading the latest GeForce Game Ready drivers. Second, GeForce Experience intelligently optimizes graphics settings for all your favorite games based on your hardware configuration.

Some enthusiasts will view (excuse the pun) altering settings to get the very best from a game one of the ‘fun’ elements of owning a powerful graphics card. Others just want to play their game of choice without the endless testing and benchmarking to determine what settings work best. Many don’t have the inclination or indeed the time to learn what effect each setting has upon the games visual elements.It soon becomes a bind when upon a new driver release those settings which were great before can be bettered (or lowered) for a better gaming experience. FXAA, TSAA, MMAA or simply AA. Low, medium, high, ultra texture settings along with overall visual settings can be all too confusing when configuring a games visuals and while it would be easy to just crank everything up to maximum and hoping for the best, this all too often results in choppy, unplayable gaming ruining the gaming experience.

NVIDIA’s GeForce Experience removes much of the guess work when configuring a game thereby giving users the means to jump straight into the game with the best optimised settings for there hardware.

This handy utility will also keep your GPU updated with the latest driver that can be set to automatically download, ready to be installed as soon as they are available and also it gives you access to the beta drivers.

How does it work?
GeForce experience requires an internet connection which, once connected to the NVIDIA Cloud datacenter will download optimal game settings that are tailored to your PC based upon CPU, GPU and monitor resolution.

Low end hardware will have the visuals reduced to improve framerates while high end hardware will inevitably have higher settings assigned. This is all done with a click of a button which ensures that the game not only looks great but perhaps more importantly, plays smoothly.

Testing of the settings are done by NVIDIA themselves who benchmark the game, set a framerate target to ensure smooth gameplay then adjust the settings to ensure both framerate and smooth gameplay are optimised.

In our own tests, the utility worked well and is great for those who want to jump straight into the game with the minimal of fuss and furore of adjusting GPU settings.

Our one complaint is that the supported games list requires expanding. While most of the popular games are supported, many, especially some older but very popular titles are not.

Packaging & Accessories

The ZOTAC packaging is very attractive. There are no signs of childish dragons or mythical beast to exemplify the power of the card. Instead we get a straightforward, minimalist yet smart design that tells us most of what we want to know such as what the card is and how much memory it has.

The sides of the box tell us more about the specifications and PC requirements to run the GPU. Flipping the box over to its rear and we get a basic line diagram, explanation of the GTX 760 and beneath in multiple languages, what is included in the box.

Like the packaging, the accessory list is basic but has everything required including 2 PCIe-twin MOLEX adapters which is a nice addition to the single one usually added. This means that even those with the most basic of PSU’s, without any PCIe cables have the potential to get the card up and running assuming it meets ZOTAC’s recommended PSU rating of 500W.

First Look

The ZOTAC GTX760 features are fairly anonymous looking cooler atop of a black PCB. the only difference between this and the reference version we also received from NVIDIA is the ZOTAC card has a screen printed logo on the fan. Other than that you would be hard pushed to tell the two cards apart.

Another minor difference between the ZOTAC and reference designs is that the ZOTAC card features a matt black PCB whereas the NVIDIA version has a sheen to it. We prefer the ZOTAC version but you would beh ard pressed to tell the difference in a PC enclosure. As you can see from the shot above, the PCB is actually much shorter than the cooler. The whole card measures just 24cm however this could quite easily be shortened with a redesigned heatsink assembly bringing the length of the card to the PCB’s 17cm.

Another minor difference with the ZOTAC card is that they have omitted the lime green GEFORCE GTX logo which is printed along the leading edge of the reference design.

The card requires two 6-pin PCIe power cables with a PSU capable of delivering 500W (recommended by NVIDIA).

Thankfully, the ZOTAC GTX760 is multi SLI capable meaning this card can be matched up to more than one other GTX760.

The I/O area is a standard affair featuring DVI-D, DVI-I, HDMI 1.4a and a full size DisplayPort. The remaining area is taken up with vents to allow hot air to be exhausted out of the PC enclosure. We like how ZOTAC colour code their DVI ports with Orange plastic to match their brand. Little touches like this make an otherwise replication of the reference design, stand out.

Closer Look

Removing the cooler was a cinch with just 10 Phillips style screws to remove. The heatsink is actually quite small compared to the real estate afforded by the cooling shroud and as you can see, the main heatsink only covers the core, not the memory or VRM areas.

Surprisingly, the core is not fixed in anyway to the shroud, rather it is simply sandwiched between the card and shroud and only becomes fixed when all the components are screed together. With GPU boost dependent on temperature, it was surprising to see such a basic design. Hopefully this will not have an affect on our overclocking results!

The card has the VRM at opposite ends to the power ports which is not the most efficient design. As you can see, the VRM area has it’s own passive heatsink attached via push-pins. There are a total of 8 empty GDDR5 ram slots (4 on each side of the PCB) which hints at the potential of 4GB models becoming available in the future.

The VRM is made up of a 4+2 phase design with each GPU YAGEO R22 choke coupled to 3 MOSFETs. The remaining two R33 chokes have a single MOSFET each and are reserved for memory and PLL operations. The whole PCB carries solid state capacitors which is a familiar sight now with all modern graphics cards.

The memory is high quality HYNIX carrying the product code of H5GQ2H24AFR R0C so should be good for some overclocking fun.

The GK104 core is an excellent choice as it is both power efficient and (relatively) cool running. With 6 SMX units it will be interesting to see how it compares to the HD7950 which on paper appears to be the more powerful option.

Test Setup

How we test graphics cards

Testing a graphics card is an extremely lengthy process. We sometimes see reviews where a graphic card has been tested using out of date equipment, out of date games and out of date drivers. While the latter can be excused due to the sheer amount of driver updates making a thorough review impossible we will however notify the reader when we have used a different driver to the normal for example a pre-release driver. For the most part however we will always use the same hardware and where possible the same drivers unless a newer driver rectifies an issue we have encountered or significantly improves performance to such an extent that continuing with an outdated driver is not feasible.

Frame Time Analysis
We have also seen the emergence of frame time analysis. We covered this in a separate article here: GPU Reviews: Why Frame Time Analysis is important so we won’t go into the reasoning again but to summarise, our testing comprises both FPS testing and perhaps arguably more importantly, frame time analysis. We also look at overall performance by equating averages across the games and finally before concluding our review we take a look at value for money.

HardwareWith the latest Intel chipset release we decided to update our ageing X58 setup to the new X79 chipset. Not only that but we will be using the flagship Core i7-3960X Extreme Edition processor clocked to 4.5GHz to ensure we have no CPU bottlenecks. With 16GB of ram on board there should be minimal paging so the benchmarks we run today will hopefully give a true reflection of the graphics card’s performance.

Benchmarks
If you are a regular reader of our reviews you will know we like to test the latest hardware with the latest games and benchmarks on the market. Here are the games we have chosen:

Battlefield 3
Crysis 3
Far Cry 3
BioShock Infinite
DiRT: Showdown
The Elder Scrolls: Skyrim

We also take into consideration the benchmarkers out there so have included 3 of the more popular synthetic benchmarks available:

Unigine: Valley
Unigine: Heaven 4
Futuremark 3DMark Firestrike

Let’s see how today’s graphics card performed…

Temperature, Acoustics and Power Consumption

Power Consumption

To test for power consumption we use the included iPower Meter found with our Thortech PSU. As system load figures obviously differ from idle it is extremely difficult to get an accurate figure of system draw and then simply take this figure away from the overall amount because each game will generate varying levels of CPU and hard drive activity. Dynamic power adjustments which fluctuate in game will also affect accurate power figures thus rendering any such power consumption calculations redundant at worst and approximate at best.

We will therefore take our system readings averaged over a benchmark run of Tessmark (100% load) and after 20 minutes of being idle in Windows 7. These can then be used as a comparison to other graphics cards to determine how much more or less power you can expect a GPU to consume.

ZOTAC recommend a PSU capable of 500W. We however believe you could possibly get by with a smaller PSU given that both our GTX760 samples pulled much less than this. It is however worth bearing in mind that you will need twin 6-pin PCIe power cables which are unlikely to come with a low specification unit.

Temperature

To test temperatures we measured idle temperatures after booting windows, letting all applications finish loading and ran a few benchmarks. Once the benchmarks were complete we left the card to reach a cooling plateau where we then took the idle temperatures. For the load tests, we would normally run Furmark for 20 minutes, taking the absolute maximum temperature attained however we found that this throttled the card and resulted in spurious results. So we set Heaven running continuously for 20 minutes and used this as a temperature result as the card did not throttle with this application.

The new range of GPUs from NVIDIA will keeping upping the clockspeed until either a power or temperature target is reached – usually the latter so with a threshold of 80c set on the reference card this is where the temperature maxxed out.

Acoustics

The card is neither silent nor extremely noisy. With such a hollow shroud, the noise is heightened somewhat when the card is put under load. It certainly is not screeching loud, far from it but it is noticeable above our case fans when running under load conditions for a while. Thankfully there was no capacitor squeal.

Let’s see how the card performs in our suite of benchmarks…

Futuremark 3DMark Fire Strike (Synthetic)

Fire Strike is the new showcase DirectX 11 benchmark designed for high-performance gaming PCs. It is Futuremark’s most ambitious and technical benchmark ever, featuring real-time graphics rendered with detail and complexity far beyond what is found in other benchmarks and games today.

*Note* SLI results omitted due to inconsistent results with driver 320.39.

Unigine: Heaven 4 (Synthetic)

Heaven Benchmark with its current version 4.0 is a GPU-intensive benchmark that hammers graphics cards to the limits. This powerful tool can be effectively used to determine the stability of a GPU under extremely stressful conditions, as well as check the cooling system’s potential under maximum heat output. It provides completely unbiased results and generates true in-game rendering workloads across all platforms.

Unigine: Valley (Synthetic)

Valley Benchmark is a new GPU stress-testing tool from the developers of the very popular and highly acclaimed Heaven Benchmark. The forest-covered valley surrounded by vast mountains amazes with its scale from a bird’s-eye view and is extremely detailed down to every leaf and flower petal. This non-synthetic benchmark powered by the state-of-the art UNIGINE Engine showcases a comprehensive set of cutting-edge graphics technologies with a dynamic environment and fully interactive modes available to the end user.

Battlefield 3 (FPS)

Battlefield 3 leaps ahead of its time with the power of Frostbite™ 2, the next installment of DICE’s cutting-edge game engine. This state-of-the-art technology is the foundation on which Battlefield 3 is built, delivering enhanced visual quality, a grand sense of scale, massive destruction, dynamic audio and incredibly lifelike character animations. As bullets whiz by, walls crumble, and explosions throw you to the ground, the battlefield feels more alive and interactive than ever before. In Battlefield 3, players step into the role of the elite U.S. Marines where they will experience heart-pounding missions across diverse locations including Paris, Tehran and New York.

Average and minimum frames per second were measured using Fraps during the parking lot scene on Operation Sword Breaker. High and Ultra presets were loaded at both resolutions.

Crysis 3 (FPS)

Crysis 3 from Electronic Arts is the fourth instalment of the Crysis franchise and sequel to Crysis 2. It uses the CryEngine 3 gaming engine which is perhaps the most advanced gaming engine to date and therefore the most demanding. The meme ‘Can it run Crysis’ has never been so apparent…

Far Cry 3 (FPS)

Far Cry 3 is a tropical survival shooter video game from Ubisoft Montreal and Massive studios. It’s open world design has similar traits to it’s forbear Far Cry 2 but it does it all so much better. With stunning visuals and settings to bring a PC to it’s knee’s, this game is so much more than the ‘just another console port’ it was reported to be.

BioShock Infinite (FPS)

Set in 1912 during the growth of American exceptionalism, BioShock Infinite is a thrid person shooter developed by Irrational games and published by 2K Games. It is the third instalment of the BioShock franchise. the game utilises the Unreal Engine 3, modifying it with their own lighting engine to present a visually stunning experience like no other.

DiRT: Showdown (FPS)

DiRT Showdown is the new arcade racing game from the team that brought you the award-winning DiRT series, uncaged in 2012. Pick up and play controls combine with electrifying events, frenzied crowds and stunning graphics to deliver high octane, dive in and drive thrills from event one.

The Elder Scrolls: Skyrim (FPS)

Skyrim is not a direct successor to the very popular Oblivion. Instead it takes place 200 years after the events of Oblivion. The non-linear playing that made the Elder Scrolls such a popular series does however make a return along with the beautiful scenery the encompasses the world of Skyrim.

Average and minimum frames per second were measured using Fraps during the drop down passage to Riverwood. V-sync was disabled to allow fluctuating (higher the 60) FPS for these runs. It is however recommended that v-sync is left enabled during normal gameplay due to the games dynamics.

Value For Money

We make a simple calculation for this set of results. For each game we add all of the resulting FPS totals together and then divide by the four sets to give us an overall performance figure. While the figures alone do not give you an accurate picture of how the card will perform in any given scenario, they do tell you, when averaged, which GPU is the more capable across all of the benchmarks and settings tested.

Gaming Experience (Frame Time Analysis)

Here we take a look at both average (black) and 99th Percentile (coloured) response times of the graphics cards. It is highly unlikely a user will notice any micro stutter (also incorrectly referred to as lag but the effect can be interpreted to be similar) at anything below 30ms but every gamers perception differs.

Comment

The graphs above may appear very daunting however, what you want to see is a smooth line (not fuzzy) with very few peaks and troughs. While you are unlikely to notice peaks and troughs below 30ms, any peak above 30ms may be seen as a stutter during gameplay. This will however depend greatly on your own perceptions. Multi card setups are more likely to show frame lag due to the nature of cross communicating to render frames.

Average and 99th Percentile response times (Frame Time Analysis)

Overclocking (GPU BOOST 2.0)

For overclocking our NVIDIA cards we will be using EVGA’s Precision too (ver 4.0) as this gives us all of the options we require.

Above is a screenshot of GPU-Z showing the reference speeds and reference boost clocks. We found it very odd that ZOTAC had added a very small overclock of 13MHz to the NVIDIA reference speed of 980MHz. Nevertheless, intentional or not, any factory overclock is welcomed.

Above is a screenshot of the actual overclock we achieved via Precision. With both power and temperature target sliders maxxed we hit a wall at around +145MHz on the core so we reduced this by 5MHz to ensure rock solid stability. This overclock is just 5MHz more than the reference design so we would expect stable overclocks by other board partners to be around the same, given the same operating conditions.

It is possible to add a single increment of voltage (12mv) however this made no difference to the overclock of our sample.

After settling on our stable clockspeed which was verified by multiple runs of Unigine Heaven and 3DMark we benchmarked the overclock and compared it to stock results with Unigine Heaven 4.0 to evaluate the benefits of overclocking the GPU.

Conclusion

The ZOTAC GTX 760 is a good mid-range card. What impressed us most was the SLI capability of the GTX 760s which took apart the GTX 780 and equalled the mighty GTX TITAN. Separately, the GTX 760s have an R.R.P of £209 which is some £30 cheaper than the HD 7950 so given the choice, if we gamed at 1920x1008p like the majority of gamers, the GTX 760 would be the card to go for. Put two together at a cost of £418 and you have a gaming setup that is not only cheaper than the best fastest single core GPU available (GTX TITAN), it matches it and even betters it on occasions!

While we expect to see many variations of cooling design for the GTX 760, today’s sample was simply a reference design which niether impressed nor let us down. Yes it is basic but it does the job fine. We can only assume though that with better cooling, overclocks would increase thus truly unleashing the power of this card.

As it stands though, the GTX 760 offers good value in singular form and great value when SLI’d. We were stuck on an award for this card because on the one hand (SLI) it is a fun setup that compares favourably with regard to price. On the other hand, gamers who want to add filters and up the gaming details, the GTX 760 may start to fall a little short. We therefore think that our silver is a fair appraisal of the product reviewed but we will also add the value award because for the money, having two of these cards in SLI will be hard to beat.

To summarise

The ZOTAC GTX 760 offers good value for money and excellent performance at popular resolutions. SLI them and the performance increases are fantastic. You don’t even have to sell a kidney!

Pros
+ Good Value
+ Good FPS performance
+ Excellent SLI capability

Cons
– Begins to struggle at high resolutions
– Basic cooling
