内容：
"It's about time," is my first reaction. Six months of dragging this out has lost a lot of face with your consumers and with guys like myself. While we can only hope that ATI would come up with an alternative to GeForce 8800 and now 8600, the reality is that some markets get lopsided. Nvidia was first to market and now has a strong head start. Even some ATI fanboys have changed their tune with such a long dry spell.
Personally, I like all of the advanced hardware inside of R600. I am very happy with the implementation of the AVIVO hardware with its audio controller, embedded HDCP key and new HDMI adapter. I have always been a fan of the memory ring. It is advanced. A threaded design with 512-bits in each direction is a memory solution that can deliver some serious bandwidth. The organization of some of the units could have been done a little better. In particular, the number or texture units could have been higher and more importantly, why not build a purely scalar design? Not that it is imperative, but why not? Other than those two items, it should have been faster, more powerful and here a long time ago (wait, I said that last one already **hint, hint **).

Based on the 80-nm process, one can conclude that this is the product we should have had the first time we were told R600 was coming. That being said, it does not put it past speculation that a faster card is coming soon at 65 nm. The only issue there is that Nvidia could have another card available with improved hardware before this next set is here.

Source: Sapphire Technologies - The HD2900XT Toxic is water cooled.For now, if you were waiting for R600, it is a good thing you did. There are some really nice advances incorporated into the HD 2900XT and the Vista performance of the 1GB GDDR4 cards have made it the choice of boutique system builders (I just wish we had them in house). At $400 for the version we have in the lab, it is a good price as it has more to offer than the GeForce 8800GTS. The sweet spot is still the 320 MB version of the 8800 GTS but that could change as other versions of the R600 family emerge. Until then, if you were sitting on the fence, you can either keep riding or finally spend you money on something. Versions like the Sapphire HD2900XT Toxic will come factory overclocked with a stand-alone water cooling solution.
Overall, HD2900XT is more forward looking than GeForce 8800 and it should be; it took an extra six months getting it to market. If you are leaning towards longevity of a card, R600 looks more attractive with a dedicated tessellator, programmable filters, high-clock speeds and crazy amounts of bandwidth. It is a hot and a little loud. It is hot enough that a warning label might soon accompany cards and systems. We can only hope that it will become more cool and quiet as more cards hit the market.

Final Thoughts

   We are going to look a little more into the power consumption of the cards as we found some interesting behaviors within GeForce 8800GTX and R600. To wet your appetite, here are a few of the findings. For starters, R600 drew less overall system power than GeForce 8800GTX in the game tests. I personally want to try more applications and settings to see why this happened.

	No Cards - ATI	HD2900XT	HD2900XT CF
Boot	163	243	287
Boot 2		311	455
OS Idle		296	421
OS Idle 2		250	428
3DM06 HDR1 - GT3		358	549
3DM06 HDR2 - GT4		343	527
	No Cards - Nvidia	8800GTX	8800GTX SLI
Boot	164	254	292
Boot 2		266	296
OS Idle		217	230
OS Idle 2		227	233
3DM06 HDR1 - GT3		343	569
3DM06 HDR2 - GT4		347	519

There is a lot to discuss regarding R600 vs. G80/84/86. Does internal bandwidth affect the performance of Nvidia's texture units? "Does the five-scalar VLIW hinder performance because there is only one SIMD per block of ALUs? No, it should not, but this and many other questions are being answered through testing and conversations with the manufacturers. Our AVIVO testing needs an update and we need more cards to compare HD 2900 to. We will definitely have more on these subjects over the coming weeks.

只好我来献丑了。
大意：
"It's about time," 是我的第一反应。经过六个月的拖延才展现在消费者面前。我们当然希望ATI的产品可以抗衡GeForce 8800和新的 8600，现实是市场已经倾斜。Nvidia销售位居第一，而现在又占了先机。漫长的讽喻也使得一些ati fanboys 忍气吞声。
现在，我亲自感受r600拥有的先进硬件技术。我非常愉快的从音频控制器启动了AVIVO硬件，嵌入式HDCP和新的HDMI适配器。······（实在懒得思考了，略过。以下摘取重点句，别说我短章取句）。

Source（来源）: Sapphire Technologies（蓝宝石）HD2900XT Toxic 是水冷散热。当前，如果您等待R600，那您做的一件好决定。（接下来说）1GB GDDR4卡将能更好的展现“风景”，$400的蓝宝石HD2900XT Toxic 比GeForce 8800GTS有更好配件，独立水冷可oc，可编程序的过滤器、超高时钟速度和可观的带宽，但它是热了些，且噪音大了点。当更多的卡进入市场时，我们可以希望它将变得更加凉快和安静。

最后的想法
说了GeForce 8800GTX和R600功耗测试，结果见表格。

	No Cards - ATI	HD2900XT	HD2900XT CF
Boot	163	243	287
Boot 2		311	455
OS Idle		296	421
OS Idle 2		250	428
3DM06 HDR1 - GT3		358	549
3DM06 HDR2 - GT4		343	527
	No Cards - Nvidia	8800GTX	8800GTX SLI
Boot	164	254	292
Boot 2		266	296
OS Idle		217	230
OS Idle 2		227	233
3DM06 HDR1 - GT3		343	569
3DM06 HDR2 - GT4		347	519

有很多关于R600 VS G80/84/86 的谈论。如，内部带宽是否影响Nvidia的纹理单位表现？或者，five-scalar VLIW 妨害表现，因为ALUs仅有一个SIMD（看着晕，谁来解析）。不，不应该，但是这和许多其他问题通过测试和与制造商交谈被解答（费脑筋）。AVIVO测试的需要更新，HD 2900 需要更多的比较，我们确定未来将有更多的测试。

好累（占用率从100%降至50%），完成。

千呼萬喚始出來的AMD R600，終於走出制程轉換、GDDR4缺貨等陰霾成功登陸市場，為不少"A"卡Only的AIB合作伙伴燃起全新希望，儘管較對手推出時程慢上2季，但仍及時趕在DirectX 10遊戲面市前現身，由於大部份有著高階繪圖卡使用需求的玩家，目前對於DirectX 10產品皆抱持觀望態度，令DirectX 10繪圖卡升級潮尚未引爆，因此市場普遍預期，性價比表現相當不錯的AMD Radeon前景相當樂觀。

ATI Radeon HD 2900XT雖然未能在效能上，取代GeForce 8800 Ultra成為繪圖效能之皇，但$399美元漂亮售價，不僅與GeForce 8800GTS相約，效能亦高出5 ~ 30%，並直逼GTX，性價比令人十分滿意。

值得一提的是，R600繪圖核心加入HDMI支援，令其可輕鬆支援市面上大部份高清顯示器，對於影音玩家來說，絕對是一大賣點，G80目前暫時只能望其項背。

但令人擔憂的是，R600功耗相對較高，不少用家可能需要升級電源供應器，才能應付此吃食電怪獸，對此，HIS也提出解決方案，祭出「PowerUp! Edition」，附送400W VGA專用電源供應器，售價僅提高約$35 ~ 50美元，絕對是貼心的設計，可望吸引許多玩家眼球。

事實上，此次測試僅能為這些次世代繪圖卡，進行較準確的DirectX 9遊戲測試，無法完全反映其DirectX 10處理能力，因此R600與G80誰能成為最終皇者，目前仍言之過早。

但值得注意的是，NVIDIA與多家遊戲廠商的合作關係，相較AMD來得緊密許多，這是AMD現階段須急迫解決的一環，因為就算有著強大的硬件效能，若無法獲得軟件上的優化，始終得物無所用，而更重要的是，AMD必須拿出高功耗的解決之道，方能無懼迎戰對手擺下各路重兵。

雖然$399美元的高階繪圖卡市場，Radeon HD 2900XT輕鬆地拿下首勝，但也別高興得太早；以靈活反應見稱的NVIDIA勢必不會坐以待斃，近期是否會祭出削價戰或是推出超頻版本？已平靜無波一段時間的高階繪圖卡市場，將再次風起雲湧。

With all due respect, don't consider me as a picky person or anything else, but I really wanna pin something out from your translation to correct. Unfortunately there is too much for me to fix up, so I quit! Anyway it's always gonna be a pain in the ass trying to be a good translator.

R600基本上就是NV30再世，已经可以盖棺定论的事情

这说法有点搞笑:p
