R580+ to give Quad SLI a run for its money?
Just as NVIDIA opens up Quad SLI to the enthusiast crowd, early
benchmarks of ATI's upcoming Radeon X1950 XTX have
surfaced. The benchmarks stack a pair of X1950s running in
CrossFire mode against two GeForce 7950 GX2 dual-PCB graphics cards
running in Quad SLI. Surprisingly, the numbers show the dual
Radeons consistently outperforming the quad GeForces in games like Call
of Duty 2, Half Life 2: Episode One, Quake 4, and Oblivion at resolutions 1600x1200
and higher with 4x antialiasing and 8x anisotropic filtering.
That said, the benchmarks seem to come from either ATI or its
partners, so there's no telling how accurate they are—both ATI and
NVIDIA often release highly optimistic numbers for their products.
Fortunately, the Radeon X1950 XTX's performance may not remain a
mystery for long. According to recent leaks, the card is scheduled to
launch between August 23 and August 27. It will include a R580+ graphics
processor running at 650MHz with 48 pixel shader processors, and sport GDDR4 RAM running at an effective 2GHz.
