Fudzilla: "We received an opportunity to get Sapphire's Radeon HD 5970 card in our lab before the weekend and attempted to publish a few benchmark numbers as quickly as possible. As many readers know by now, this is currently the fastest graphics card on the planet and steals the perfomance crown from Nvidia's almost year-old Geforce GTX 295. At the same time, this is the first dual-GPU card with DirectX 11 support.
The GPU cores in Sapphire's Radeon HD 5970 run at 735MHz, a modest 10MHz above the reference clock. The entire card features 3200 stream processors (2x 1600) and 2GB of GDDR5 memory at 1010MHz for 4040MHz overall effective speed. The rest of the hardware specifications include 160 texture units, 64 ROPs, 116 Gtexel/second texture fill rate and compute performance slightly above 4.64 Tflops. The card's pixel fillrate is 46.4 Gpixels/second, its Z/stencil performance is 185.6 Gsamples/second and the memory data rate is 4.04Gbps."
