HD 4870 X2 to support octo-CrossFire, apparently
The HD 4870 X2 is going to be available in August. There will be two different flavors for that, available at different price points.
As an aside, AMD has already built a computer that has four 4870X2s in it. So it has eight GPUs; drivers will not be supporting eight GPUs at this point of time.
With the 3800 series, we knew we had an opportunity to work with 55nm. So we decided, ‘let’s do that in the shortest possible time without making design changes and the architecture changes’. So we took the 2-series and shrunk it down and got the power and cost advantages that you get with the 3-series. But for the 4-series — we started while 3 was happening said, ‘we have to take it to the next level.’
