RV790 Samples Carry Faster Memory
Having taped out late last year, samples based on the new RV790 graphics processor have been doing rounds in the industry. A few more details have surfaced about it. Earlier noted to have identical clock speeds to that of the RV770XT (Radeon HD 4870), the RV790 samples are now known to have higher memory clock speeds. While the Radeon HD 4870 has its memory frequency at 900 MHz GDDR5 (effective 3.60 GHz), the samples carry memory clocked at 975 MHz (effective 3.90 GHz). Interestingly the memory chips on the sample, labeled IDGV1G-05A1F1C-40X, made by Qimonda, are specified to run at 1.00 GHz, reaching the 4 GHz effective memory speed mark. The samples feature 1 GB of memory. The RV790 is AMD's new current-generation graphics processor built on the newer 40nm silicon fabrication process. The new process is expected to reduce the GPU's power consumption and thermal footprint. The RV790 is conceived to be an immediate successor to the RV770 GPU.

Anywho-
It will be the counterstrike to the GTX260 216.
This will be good for ATI, if 65nm to 55nm is anything like 55nm to 40nm it will be a great overclocker.
Maybe now would be a good time to invest in them :P
Anyway 40nm will probably be a deciding factor, because both will have their next high-end cards around the same time.
and by the way , can do crossfire with old 4870
