Benchmarks provided to vendors for the Radeon X1950XTX CrossFire versus GeForce 7950GX2 Quad SLI - Click to enlarge
Radeon X1950 CrossFire puts Quad SLI in its place
has received early benchmarks of
ATI’s upcoming Radeon X1950XTX and X1950 CrossFire graphics cards
upcoming Radeon X1950XTX and X1950 CrossFire is expected to make its debut on August 23rd
. Specifications for the Radeon X1950XTX and X1950 CrossFire are finalized with a 650 MHz core clock and 2 GHz effective memory clock. The core clock is unchanged from the previous Radeon X1900XTX while memory clock receives a hefty 450 MHz boost. This time around the Radeon X1950XTX and X1950 CrossFire are equipped with
90nm Samsung GDDR4 memory
The benchmarks compare ATI’s Radeon X1950XT in CrossFire against
NVIDIA’s Quad SLI
. The test setup used for NVIDIA’s Quad SLI is a
Dell XPS 700 system
equipped with an
Intel Core 2 Extreme X6800
, 1GB of DDR2-800 memory and
two GeForce 7950GX2 graphics cards for four total GPUs
. The ATI CrossFire test system is identical with the Quad SLI system except the
nForce 590 SLI Intel Edition
motherboard was swapped out for an early
Radeon Xpress 3200 (RD600) motherboard
and two ATI Radeon X1950XTX/CrossFire graphics cards.
These early benchmarks are favorable to ATI. Call of Duty 2, Half-Life 2: Episode 1 and Serious Sam II heavily favor ATI, most likely due to better multi-GPU scaling on ATI’s side. FarCry, Quake 4 and Doom 3 performance shows the Quad SLI system creeping up to the performance of ATI’s X1950XTX/CrossFire system. However, the Quad SLI system still falls behind, close but no cigar. F.E.A.R. is the only game that can take advantage of Quad SLI and shows the Quad SLI system beating out the similarly configured X1950XTX/CrossFire system; though at 2560x1600 with 4xAA and 8xAF the X1950XTX/CrossFire takes the lead once again. With Elder Scrolls IV: Oblivion the X1950XTX/CrossFire system manages to take a nice lead over Quad SLI at 1600x1200 with 8xAF. The lead narrows when the resolution is raised to 2560x1600 with 8xAF.
While these early benchmarks show ATI’s X1950XTX/CrossFire beating out NVIDIA’s Quad SLI there’s more to the story. Since the benchmarks are only comparing performance with 4x anti-aliasing and 8x anisotropic filtering at most, it doesn’t show the true performance of NVIDIA’s Quad SLI. The true performance of Quad SLI being its capability to render high levels of anti-aliasing without taking a heavy performance hit.

Quad SLI Draws Less Power Than Crossfire
8/10/2006 11:55:29 PM
I'm almost positive about seeing the 7950 GX2 consuming less power than a single X1900XTX. With that in mind, I think the GX2s in Quad SLI should consume about the same amount of power as the X1950 in Crossfire, assumimg that the X1950 is built on the 80nm process and that GDDR4 uses less voltage than GDDR3. I'm not sure if the 80nm process was just an unclarified guess.
ATI vs. nVidia and DX10
8/14/2006 11:18:12 AM
Right now ATI has better image quality, can have AA + HDR on in games like Oblivion and Far Cry. nVidia cards can't.
Also, the DX10 cards of the G80 series first hand will be horrible. First off, you need a powerplant to run a single card. Either buying a 1200w PSU or an external PSU. So much for saving on Power consumption.
So these cards would be an excellent investment til next year when both companies start getting their act together and pump out decent power consumuing cards.

Don't wuote me ont hsi but I think this card is based on 80nm rather than the 90nm of the previous card, I know it has a much better heatsink this time round though, its much like you can buy from Arctic Cooling (or the ones that come fitted on the HIS cards) so it'll run cooler and more quiet than the 1900XTX, if the die shrink is correct then it also means it should suck less juice.

Spelling issues aside, it might also be worth noting that the nVidia SLI chipset for Intel is pretty damn poor performance wise.
