More details leak out about Radeon X1950, X1650

Information has been progressively leaking out about ATI's upcoming Radeon X1650- and X1950-series graphics cards, and new reports on HKEPC seem to have sealed the deal. The Chinese site 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. Previous rumors said the RV570 chip would replace the current R580 in Radeon X1900 GT graphics cards, but if these slides are accurate, ATI has opted for a less confusing approach. 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.

Also in October, ATI plans to bolster its low-end lineup with an RV560-based Radeon X1650 XT graphics card, additional slides show. With 24 pixel shader processors and 600MHz/1.4GHz core and memory clocks, the slides say the X1650 XT will trounce NVIDIA's GeForce 7600 GT. The Radeon X1650 XT will also feature CrossFire support via an internal cable, an implementation similar to NVIDIA's "golden finger" SLI bridge.

According to HKEPC's report, ATI is planning some aggressive pricing for these new SKUs. The X1950 XTX will start at $399, while the X1950 Pro will be priced at only $199-249. The X1650 XT will sell for $149-199—the same price range as the GeForce 7600 GT. Below $149, ATI reportedly plans to introduce a rebadged Radeon X1600 XT with a die-shrunk 80nm GPU under the X1650 Pro moniker. The existing X1600 Pro will suffer a similar fate, becoming born again as a Radeon X1300 XT.
