The Chinese site HKEPC has nabbed ATI slides that say Radeon X1950 XTX will feature 48 pixel shader processors, a 650MHz core clock, and 2GHz memory. Rumors say this memory will be of the GDDR4 variety. The Radeon X1950 XTX will apparently launch in one month, between August 23 and August 27. The slides also reveal that a Radeon X1950 Pro is in the works. Where the X1950 XTX will be built around ATI's R580+ graphics processor, the X1950 Pro will be based off the RV570 GPU. The Radeon X1950 Pro will have 36 pixel shader processors, 600MHz/1.4GHz core and memory speeds, and "no compromise" internal CrossFire multi-GPU support. The slides claim the card will one-up NVIDIA's GeForce 7900 GT and that it will be available in October.
