TSMC's 55nm process technology has already done wonders for the new Radeon HD 3850 and 3870 graphics cards from AMD, and it's scheduled for an encore early next year in the form of a new RV635 graphics processor. Rumors about the RV635 GPU popped up back in September claiming the chip would be 55nm shrink of the RV630 used in Radeon HD 2600-series cards. A report by DigiTimes now quotes more detailed specifications and launch time frames for RV635-based cards.
The report says the RV635 will roll out in an "XT" card in January, followed by a "Pro" variant some time in February. The XT will run at 800MHz and will pack 256MB of GDDR3 memory running off a 128-bit memory bus. An RV635 Pro will run at 600MHz and incorporate 512MB of GDDR2 RAM also running off a 128-bit bus. Previous rumors suggest the two cards will include support for DirectX 10.1 features and PCI Express 2.0 connectivity, as well.
