ATI ALSO HAS plans for the high end, like Nvidia's, which we revealed here.

ATI is preparing a R420 AGP swizzle stick for Q2 this year. Cards will use GDDR 2 memory 256MB at 256 bits. It's possible to use 128 implementations as well. This chip be able to support DDR, DDR2 and GDDR3 so whenever it's ready ATI can make it work with its current memory controller. They will of course use 8x32MB chips.

The chip itself will be produced using a 0.13µ process and we are quite certain that it will use its heavily marketised low k process as before.

Cards will use Pixel Shader 3.0 that is part of 3.0 specification and actually has been with us for quite some time, but Microsoft still needs to fix few bugs to make it work, that's the whole point of DirectX revision 9.0c.

A possible launch date is CeBIT but this date isn't chiselled in stone. If ATI doesn't choose CeBIT, it will be round up the time, either soon before or soon after. µ
