"最近我們已經獲得確認，ATI R420(AGP Radeon X800)將在4月26日上演處女秀，官方名稱
為Radeon X800 Pro。Nvidia NV40(GeForce 6800)將在4月13日正式宣布，但是零售時間大
約將在4月26日。注意，在4月13日發布的NV40產品是GeForce 6800，而不是GeForceFX 680
0。ATI對R420的命名機制保密工作做的很好，但是我們從廠商聽到的是"Radeon X800"。
引人注意的是僅僅在Radeon X800 Pro宣布一個月之后，Radeon X800 XT將在5月31日發布
。要知道此前Radeon 9800和9800 XT的發布時間相隔有6個月之久。我們估計ATI改變了市場
策略，又或者是NV40和R420的性能差異加速了ATI的計划。由於在ATI產品規划上沒有非Pro版
本的Radeon X800，因此XT可能代替了Pro系列，而Pro則取代了非Pro。盡管首批Radeon X8
00將採用256MB GDDR3顯存，但是最終我們將看到512MB版本，最后，我們將看到配備128MB
DDR1的Radeon X800 SE，當然SE版本時鐘要低的多。
NV40也打破了Nvidia的命名機制，FX名稱已經被去掉，NV4x GPU家族是否會有GeForce和Ge
ForceF兩個獨立的版本？當然這僅僅是猜測。
R420的PCI-Express版本，將在6月14日發布。R423估計將和R420相同，名稱也將採用Radeo
n X800。Nvidia的橋接PCI-Express版本將和AGP版本一起在4月13日發布。
RV380和RV370也將採用新的產品名稱，分別是Radeon X600和Radeon X300。"
-----------------原文
Recently we received confirmation that the first retail samples of ATI's R420 (
AGP Radeon X800) will debut April 26 as Radeon X800 Pro. NVIDIA's NV40 (GeForce
6800) officially launches April 13th, but retail availability will occur around
April 26th. Notice the NV40 product to be released April 13th is GeForce 6800,
not GeForceFX 6800. ATI's naming scheme for R420 has been closely guarded as
well, but the open term we hear from vendors is "Radeon X800."
What seems highly unusual is the scheduled introduction of Radeon X800 XT on
May 31st; only a month after Radeon X800 Pro's unveiling. Recall that Radeon
9800 and 9800 XT were launched six months apart. We can speculate ATI has
either changed their marketing strategy, or the difference in performance
between R420 and NV40 hastens ATI's release schedule. Further inspection of the
ATI roadmaps reveals that "Non-Pro" Radeon X800s are absent. Perhaps "XT" has
replaced the "Pro" Radeon series, and "Pro" thus replaced the "Non-Pro" Radeon
series. Even though the initial launches of Radeon X800 will use 256MB of GDDR3
, before the end of the year we also anticipate a 512MB revision. Furthermore,
we will almost certainly see Radeon X800 SE with 128MB of DDR1; which will also
debut with much a lower clockspeed.
NV40 breaks NVIDIA's naming scheme with the removal of FX from their GeForceFX
moniker. Will we see a separate GeForce and GeForceFX in the NV4x GPU family?
It appears that is also speculation.
R423, the PCI-Express (PCX) version of R420, is scheduled to launch June 14th.
Specifications on R423 are identical to R420, and the cards will also carry the
Radeon X800 product name. NVIDIA's bridged PCI-Express cards will launch April
13th along with the AGP versions.
RV380 and RV370 will also receive new product names, as Radeon X600 and Radeon
X300, respectively. For more details about R420, RV380 and RV370, please take a
look at our previous ATI roadmaps here. Stay tuned for more ATI and NVIDA news
from the trenches.
