A few things that we know about ATI's X800PRO

Before 4th of May

HERE IS A SUMMARY of things we know about forthcoming ATI card. The card hidden under the R420 codename will be introduced on 4th of May but ATI swears blind that it won't have any launch party for it.

The R420PRO slower version will materialise a few weeks before the faster R420XT, X800XT.

The R420PRO should be clocked at a 475MHz core and 900MHz memory and will feature 12 pipelines. The memory it uses is GDDR3 in this version of the card.

The cards will be red and will be physically almost the same as Radeon 9800XT as theoretically we are talking about a chip very similar to R300 shrink from 0.15µ to 0.13µ with some more pipelines and algorithms.

The card will consume much less power then the Geforce 6800 Ultra and will have only one power connector. It will work in the Shuttle XPC and that is something that the ATI PR manager has confirmed. It will also fit into XPC as it's a one slot beast.

Cards won't have pixel shader 3.0 support as they're based on similar marchitecture to R300 core and will stick to PS 2.0 at the time being. 128 bit precision will also be missing as ATI chip can support 24 bit per colour - 96 bit altogether.

There's also the R420 features special 3Dc compression that we mentioned here

We'll tell you more about XT soon but it might end up faster that we were all expecting. µ
