X1950XTX Crossfire vs 7950GX2 Quad-Sli

[l2k]

DailyTech has received early benchmarks of ATI’s upcoming Radeon X1950XTX and X1950 CrossFire graphics cards. ATI’s 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 550 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. (...)

só usam AA 4x, ai um sistema quad sli perde até apra duas 7900gtx em sli, o quad sli só rende com 8x AA pelo menos, ai as coisas seriam mais equilibradas, mesmo assim bastante impressionante.
