AMD representatives note that at the beginning of 2008 a full range of graphics solutions will be based on 55 nm core. This of course include product like dual chip card R680, as well as single chip decisions build on RV635 and RV620. RV620 will support PCI Express 2.0 .
Here is the announcement date of all three graphics card :
- R680-> January 28, 2008;
- RV620 and RV635-> January 23, 2008.
Note that R680 is a dual chip version Radeon HD 3870 with 2 x 512 MB GDDR-4 memory . It can be assumed that a couple of R680 will be merged into Quad card configuration. Drivers with support for AMD CrossFire X will be released in the next quarter.
Video card based on RV620 will be the replacement for Radeon HD 2400. For this reason, they come in quite logical names: Radeon HD 3470 and Radeon HD 3450. .....
