GPU Testbed – Sandy Bridge-E, X79, New Games
We decided that it was high time we replaced the somewhat-dated Nehalem-based infrastructure (even though honestly, it was fast enough) with something a bit more current. Obviously, that meant going with the new Intel Sandy Bridge-E processor and X79 motherboard. By combining support for 40 PCI Express lanes and 3-4 full size GPU slots, it makes for the perfect GPU base.
From this point on, our reviews will based around the following system:
- Intel Core i7-3960X CPU
- ASUS P9X79 Pro motherboard
- Corsair DDR3-1600 4 x 4GB Vengeance memory
- 600GB Western Digital VelociRaptor HDD
- 1200 watt Corsair Professional Series power supply
- Windows 7 SP1 x64
The ASUS P9X79 Pro
The Intel Core i7-3960X gives us the fastest consumer-level CPU on the market to help eliminate the possibility of any processor-based bottlenecks in our testing (whenever possible). There are still going to be some games that could use more speed (Skyrim comes to mind) but for our purposes this is as good as you get without getting into any kind of overclocked settings. The ASUS P9X79 Pro motherboard has enough space for three dual-slot graphics cards when the time comes for testing 3-Way SLI (and CrossFire), and 8 DIMM slots should we want to go up from our current setup of 16GB of Corsair Vengeance memory.
I chose to stick with the 600GB VelociRaptor hard drive rather than an SSD as our total installation size with Windows 7 SP1 x64 and 6+ games was already hitting the 115GB range. Finally the 1200 watt power supply from Corsair offers up more than enough juice for three power hungry graphics cards while running quietly enough to not throw off our noise testing drastically.
Speaking of noise, for this article we are re-introducing our sound level testing thanks to the Extech 407738 Sound Level Meter capable of monitor decibel ratings as low as 20db. This allows me to accurately tell you the noise levels generated by the graphics cards that make in-house at PC Perspective.
Along with the new hardware configuration comes a host of new games. For this review we will be using the following benchmarks and games for performance evaluation:
- Battlefield 3
- Elder Scrolls V: Skyrim
- DiRT 3
- Batman: Arkham City
- Metro 2033
- Deus Ex: Human Revolution
- 3DMark11
- Unigine Heaven v2.5
This collection of games is both current and takes into account several different genres as well – first person role playing, third person action, racing, first person shooting, etc. 3DMark11 and Unigine Heaven give us a way to see how the cards stack up in a more synthetic environment while the real-world gameplay testing provided by the six games completes the performance picture.
Obviously this review will pit the four different GeForce GTX 660 Ti cards we have in our roundup against each other. We'll start out with looking at the cards in their out-of-box state – and how they stack up against each other in our gaming tests without any overclocking or tweaks.
- EVGA GeForce GTX 660 Ti SC 2GB – $309
- Galaxy GeForce GTX 660 Ti GC 2GB – $309
- MSI GeForce GTX 660 Ti Power Edition 2GB – $309
- Zotac GeForce GTX 660 Ti AMP! Edition 2GB – $309
Obviously with all four of our cards featuring the same price tag from Newegg.com, we are eager to see how they are able to differentiate themeselves (or not).
Is there any reason to think
Is there any reason to think that the stock version of these cards couldn’t overclock to the level of the OC cards?
For example, the regular ZOTAC card looks to have the same cooler and configuration otherwise.
No, not really, they likely
No, not really, they likely could. Just a matter of what you want out of the box really. The one thing you should watch for is the cooler and power configuration.
Ryan could you tell us what
Ryan could you tell us what the idle temps were for these cards? Just to see comparison/jump to load temps.
Sure, I’ll try to get these

Correct me if I’m wrong Ryan,
Correct me if I’m wrong Ryan, but don’t these benchmarks basically show that the 660 ti is somewhat bottle necked by the memory bandwidth?
Correct. And we thought as
Correct. And we thought as much with the drop to a 192-bit memory bus width.
Honestly knowing the memory
Honestly knowing the memory situation, I recommend the card with the highest quality memory that can be overclocked because that alone is the performance boost for this card….I swear I read a review of a 660ti with some special memory chips…I dunno
Haven’t seen any like that
Haven't seen any like that yet…
Oh yea and Kudos to Zotec
Oh yea and Kudos to Zotec with the shorter card! Good for smaller cases.
I ordered the Zotac card
I ordered the Zotac card early (19th) since I have an SFF system and the Zotac card would be the only one to fit it.
I havent recieved it yet, but thank you for reassuring me that it was a good choise.
I have seen some sites claiming that zotac has a GTX 660 Ti Extreme edition in the making. While some say this is only intended for the chinese market, do you have any info on this and perhaps more specifics, like the size, of that card?
Haven’t heard anything yet,
Haven't heard anything yet, sorry.
Great read Ryan.
It is
Great read Ryan.
It is interesting to see just how much Kepler is affected by memory bandwidth and memory type.
Though we are seeing the downsides to GK104 being spread out as a entire product range, since GK104 was “meant” to be mid-range from the start. While the GTX 680/690/670/660 TI are great cards, they still dont target the “sweet spot” in my opinion, which is in the $150 – $250 ranges (aka cards like GTX 460/560 TI/ect).
#Side note: Do you need any more good reviewers/podcasters ;), lol.
I was able to overcloxk a
I was able to overcloxk a stock 660 ti to within 10% of the speed and bandwidth of a GTX 670, which is realy great imho. The temps were below 75*C.
Yup I got my O.C. to
Yup I got my O.C. to 1038/1103/1815 w/a temp at 78*C max.
The card is a EVGA 660ti.
The card is a EVGA 660ti. Overclock the memory and you can overcome the bandwidth restriction. Then the $299 card becomes a real value especialy w/the Borderlands game included.
Agreed, the $50-60 value of
Agreed, the $50-60 value of the game is pretty enticing considering it is just a current and big name title.
It will be interesting to
It will be interesting to hear MSI’s reason for the 114% Power cap. Could it be intentional to keep the Power Edition 660 Ti from overclocking as high as the more expensive Lightening edition?

The gpu temperatures dont are rigthes
i have a msi 660 ti oc and my gpu temperatues all all times higths thand yours .
got my msi 660ti to 1145/1223
got my msi 660ti to 1145/1223 and the memory to 1727mhz resulting in just about 7000mhz with afterburner,3dmark11 standard run P 8735 with those settings P 9237.
pretty good,but the memory bandwith just sucks,metro 2033 on high settings and 4xMsaa and 16xaf i cant get more than 30fps-35fps often dropping below that in intense scenes.
do yourself a favour and spend extra for a gtx 670 as you can run even very high settings and still preform better than a 660ti,and i play only on a 1920×1080 screen.a recent test revealed that even a AMD 7750 performs better with msaa and af settings put to max due to the memory bandwith.
I just purchased 2 EVGA GTX
I just purchased 2 EVGA GTX 660 TI SC+ 3GB and they are only hitting 60C under load. I’m not sure if something was changed in the 3GB version or if I just have a good card.
