ATI DDR 4 Radeon X1950 XTX takes on Leadtek Geforce 7950 GX2

First INQpressions And gets its butt kicked
Mon Aug 28 2006, 12:33
WE MANAGED to benchmark the latest Radeon X1950 XTX card and compared it against the fastest Geforce 7950 GX2.

We know that 7950 GX 2 ends up close to $100 more expensive but we are comparing two of the fastest cards around.

You can read our review of the Radeon X1950 XTX here and so we won't get into many details. The card is clocked at 650MHz core and 2000MHz GDDR4 memory. But was this enough to beat Leadtek's PX7950GX2 TDH card clocked at 500MHz core and 1200MHz memory powered with two cores?

The X1950XTX managed to beat the 7900GX2 at 10x7 in Doom 3 by some seven frames but at 12x10 the Leadtek card is slightly faster. At 16x12, the Leadtek 7950 GX2 is already 16 frames faster and at 20x15 there is an astonishing 43.1 MHz difference. We are talking about 37.5 percent difference where Nvidia really keeps the distance.

Once you turn on the FSAA and Aniso, Nvidia takes the lead from the first. At 10x7 it is five frames faster, at 12x10 it is already 21 frames faster, at 16x12 or 27.5 FPS faster and at the last 20x15 resolution or 32 percent faster.

Far Cry 4X FSAA and 8X Aniso is tight where Nvidia leads with just a couple of FPS. We have to wait for Crysis to see the difference I guess but we reached the top of this game.

Quake 4 loves the Leadtek/Nvidia card. Even at 10x7, the 7950 GX2 is nineteen frames faster, at 12x10 its 23 frames faster, at 16x12 its a massive 27 frames faster and at 20x15 massive 34 frames faster. At 20x15 Nvidia wins by 33 percent faster.

Quake 4 FSAA 4X and 8X Aniso shows even bigger difference. It starts with 24 frames advantage for Leadtek 7950 GX2 at 10x7, it continues with twenty four frames advantage, thirty two frames difference at 16x12 and almost thirty frames difference at 20x15. At last two resolutions Leadtek card is around 25 percent faster.

Nvidia owns the FEAR stores, it has sixteen frames advantage at 10x7, nineteen frames 12x10, twelve frames faster at 16x12 and ten faster at 20x15.

Serious Sam 2 High quality settings with FSAA 4X and 8X Aniso runs ten frames faster at 10x7 on Nvidia, eight at 12x10, almost eight frames faster at 16x12 and less then seven frames faster at 20x15.

Leadtek card owns the 3Dmark03 score. It runs 10500 marks faster and is faster in every single game and test. In 3Dmark05 the difference narrows to 1450 marks only but still runs better on Nvidia GX2 card. 3Dmark06 is 1800 marks faster on Leadtek 7950 GX2 card and the card dominates all the scores. It is 1200 marks faster in Shader model 2.0 testes, seven hundred marks faster at Shader model 3.0 and HDR set of testes and almost identical on CPU tests.

In Short
We have to admit that Leadtek 7950 GX2 card did much better than we expected. It runs at least twenty five percent faster at the higher resolutions.

If you have a display that supports 16x12 or higher resolutions, you want to get 7950 GX2 card. Even at 1280x1024, the most common display resolution around, Nvidia wins in every single time. The dual-chip 7950 GX2 is still the fastest card around. The only problem is that once you plug two 7950 GX2s together it won't run that fast.

Geforce 7950 GX2 is the fastest single card around but I would not bet on it when it comes to Quad SLI, at least not for the few weeks until the alleged new driver comes. If you want more than one card, Crossfire X1900 or X1950 is a better way. ?
