AMD preps 55nm versions of Radeon HD 2600, 2400

— 9:36 AM on September 10, 2007

New versions of AMD's Radeon HD 2600- and Radeon HD 2400-series graphics cards will roll out in January 2008, according to a report by DigiTimes. Rather than their current 65nm RV630 and RV610 graphics processors, the updated cards will be outfitted with new RV635 and RV620 GPUs based on 55nm process technology. The smaller process should reduce power consumption and allow for higher clock speeds, although DigiTimes says core frequencies will only be increased to 800MHz (the Radeon HD 2600 XT already runs at 800MHz by default, while the Radeon HD 2400 XT is clocked at 700MHz).

Aside from power and performance enhancements, these updated Radeon HDs will reportedly feature DirectX 10.1 API support as well as PCI Express 2.0 connectivity and DisplayPort display outputs. Nonetheless, DigiTimes says the updated cards will retain the same circuit boards as their predecessors.
