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.
對於即將到來的ATI新顯示卡，我們對目前所知的資訊做了一些摘要的整理。
隱藏於R420這個代碼背後的卡將會於五月四日公佈，但ATI肯定地說屆時將不會有任何的發佈派對。

The R420PRO slower version will materialise a few weeks before the faster R420XT, X800XT.
R420PRO將會比更快的R420XT，也就是X800XT早幾個星期有實物上市。

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.
R420PRO的時脈應該是Core:475MHz/RAM:900MHz，有十二條繪圖管線，並使用GDDR3記憶體。

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.
R420的PCB將會是紅色且看起來幾乎跟Radeon 9800XT一模一樣，因為理論上我們談的只是一個類似R300，但從0.15製程改為0.13製程，擁有更多管線和演算法的新晶片。

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.
R420將會消耗比Geforce6800 Ultra少很多的電量，並且只有一個電源接頭。ATI的公關經理已證實R420將可以在XPC上正常運作。因為R420只佔一個插槽，所以裝在XPC裡也不會是個問題。

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.
因為R420晶片是以R300架構為基礎，所以將不支援pixel shader 3.0而只支援PS 2.0。R420也不支援128bit精確度，而只維持ATI原有的24bit色彩及96bit精確度。

翻的不好的話將就看吧
