Nvidia 7900 GT and GTX Card Mini Roundup Review

Test Setup

How we tested

With the pure speed of cards out on the market at the moment I tend to focus on gameplay in my reviews. I will play each of the test suite games on as high settings as I could possibly play them at while maintaining a frame rate that is enjoyable to play at. If the quality of the gaming looks the same at different settings then I will choose the setting with the best FPS. This differs from game to game and person to person but I play a lot of games and have played with a lot of graphics cards so I hope that I can impart a decent opinion.

To offset this angle I also run a test suite of 3dMark03, 05 and 06. These will give you some numbers on what the cards perform like at stock speeds, for comparison. I also ran 3dMark06 after overclocking the cards - to see how much of an effect the overclocking will make. Overclocking was performed using the coolbits registry hack and done as in This Thread from the OC3D forums.

Test Setup

For these high-end cards I am using an overclocked Dual Core Opteron 175. Running at speeds exceeding an FX-60 at 2.8GHz, this will hopefully allow the cards to perform up to their fastest.

AMD Opteron 175 @ 2.8GHz (watercooled)
DFI LANPARTY UT Sli-D motherboard
Mushkin Redline PC4000 running at 255 x 11 1:1 3-3-2-5
HDD: OS - 160gb Hitachi Deskstar SATA II
HDD: Gaming - 2 x 40gb Hitachi Deskstars in RAID 0
Sound: SoundBlaster Audigy 2 ZS
Power: PCP&C 510 SLi
Case: Coolermaster stacker with a lot of additional cooling

For installation I have installed the card as usual with the normal PCI-E power dongle. Checked that the card is seated correctly and powered on. I am using a clean install of Windows XP Professional SP2 with all the latest patches. I am using nvidia's latest official forceware drivers - 84.21.

 

For reference I will also be using a Sapphire X1900XTX 512mb. The ATI card was run through on Catalyst 6.3 as I had some issues with 6.4.


Cards:

Gainward Bliss 7900GT 512mb Golden Sample.
Clock speed: 550. Memory speed: 1400 (700)

XFX 7900GT 256mb "XXX" Edition. Clock Speed: 560. Memory Speed: 1650 (825)

Club3d 7900GTX 512mb. Clock Speed: 650. Memory Speed: 1600 (800)

Sapphire X1900XTX 512mb. Clock Speed: 650. Memory Speed: 1550 (775).

All game tests were run on stock speeds. Initial benchmarks were run stock speeds apart from the overclocked 3dMark06 run. All benchmarks were performed three times on each card.
