We came to know that Radeon X1900 XTX (R580) will officially be clocked at 650MHz core and 1550Mhz for the memory while the X1900 XT will be officially clocked at 625MHz / 1450MHz. The reason for the lower memory clocks for X1900 XT is unclear yet since the X1800XT is already clocked at 1.5GHz.
It is also confirmed that R580 has 16 pipelines and 48 shader processors.
More interestingly, we heard faintly that an early sample of X1900 XTX clocked at 500MHz scored 10.2K in 3DMark05 so we can safely presume that the official X1900 XTX will score over 11K.
We can expect availability at launch on 24th January and retailers are expected to have stocks a few days before the launch.
However, NVIDIA won't just allow ATi to steal the performance crown from them so G71 will be their answer to R580 and it seems NVIDIA is confident that G71 will beat R580. All it takes is a highly clocked, 32 pipes G71 to stop R580.
