NVIDIAもAMDも2009年下半期にDirectX 11対応の最新GPUをローンチしようとしている。

NVIDIAはGT300のEngineering sampleを9月に完成させ、最速で今年の12月に出荷開始とする。
一方、AMDはRadeon HD 5800（RV870）を9月後半にローンチし、出荷を10月に予定している。Radeon HD 5800はまずRadeon HD 5870と5850の2モデルが投入される。
　
さらにAMDはフラッグシップモデルとなるDual-GPUカードを2009年第4四半期に予定している。このカードは“Hemlock”と呼ばれていたものでRadeon HD 4870X2の後継となる。製品名はRadeon HD 5870X2となると思われる。Radeon HD 5870X2の詳細は明かされていないが、2GBのGDDR5を搭載し、出力としてDisplayPort, HDMI, DVIを搭載するといわれている。

RV870とGT300については過去の情報とそれほど変化はありません。GT300の方はまだ若干流動的要素がありますが、RV870は9月22日ローンチ・10月出荷の方向でだいぶ固まってきています。9月10日にはRV870に関するイベントもあるようで、その時に新たな情報が明かされることが期待されます。
Hardware-InfosにはRadeon HD 5800シリーズの価格が掲載されており、これによるとRadeon HD 5850が$279～299、5870が$379～399、5870X2が$599となっています。

NVIDIA and AMD in the second half of 2009 and the latest DirectX 11-capable GPU that is trying to launch.

NVIDIA GT300 is an Engineering sample of nine will be completed in January of this year's fastest 12 to begin shipping in January.

Meanwhile, AMD is Radeon HD 5800 (RV870) was launched in late May to September, the shipments are scheduled for July 10.

First Radeon HD 5800 and Radeon HD 5870 will launch two models in 5850.


AMD has also become a Dual-GPU flagship card 2009 has been scheduled for the fourth quarter.

This card is "Hemlock" in what was called the successor of the Radeon HD 4870X2.

Radeon HD 5870X2 product names will be considered.

Radeon HD 5870X2 has not disclosed details, 2GB of GDDR5 equipped with, as output DisplayPort, HDMI, DVI has been said that with.


GT300 and RV870 information about the past and do not change much. If there are elements that GT300 is still somewhat fluid, RV870 will launch September 22 and 10 come a long way in the direction of the ship this month finalized.Sun September 10 there will be events on the RV870, is expected to reveal new information at that time.

Hardware-Infos has the Radeon HD 5800 series on the price, according to the Radeon HD 5850 which is $ 279 - 299,5870 to $ 379 ~ 399,5870 X2 has become a $ 599.

Nvidia GT300 yields are under 2%
Just pathetic
by Charlie Demerjian
September 15, 2009


THE SAGA of Nvidia's GT300 chip is a sad one that just took a turn for the painful when we heard about first silicon yields. Nvidia's execution has gone from bad to absent with low single digit yields.

A few weeks ago, we said that Nvidia was expecting first silicon back at the end of the week, the exact date was supposed to be Friday the 4th plus or minus a bit. The first bit of external evidence we saw that it happened was on the Northwood blog (translated here) and it was a day early, so props to NV for that. That lined up exactly with what we are told, but the number of good parts was off.

The translation, as we read it, says there were nine good samples that came back from TSMC from the first hot lot. That is below what several experts told us to expect, but in the ballpark. When we dug further, we got similar numbers, but they were so abysmal that we didn't believe it. Further digging confirmed the numbers again and again.

Before we go there though, lets talk about what a good die is in this case. When you get first silicon back, it almost always has bugs and problems. First silicon is meant to find those bugs and problems, so they can be fixed in succeeding steppings.

By 'good', we mean chips that have no process induced errors, and function as the engineers hoped they would. In other words not bug free, but no more errors than there were in the design. 'Good' in this sense might never power on, just that the things that came out of the oven were what was expected, no more, no less.

Several experts in semiconductor engineering, some who have overseen similar chips, were asked a couple of loaded questions: What is good yield for first silicon? What is good yield for a complex chip on a relatively new process? The answers ranged from a high of 50% to a low of 20% with a bunch of others clustered in the 30% range. Let's just call it one-third, plus or minus some.

The first hot lot of GT300s have 104 die candidates per wafer, with four wafers in the pod Nvidia got back a week and a half ago. There is another pod of four due back any day now, and that's it for the hot lots.

How many worked out of the (4 x 104) 416 candidates? Try 7. Yes, Northwood was hopelessly optimistic - Nvidia got only 7 chips back. Let me repeat that, out of 416 tries, it got 7 'good' chips back from the fab. Oh how it must yearn for the low estimate of 20%, talk about botched execution. To save you from having to find a calculator, that is (7 / 416 = .01682), rounded up, 1.7% yield.

Nvidia couldn't even hit 2%, an order of magnitude worse than the most pessimistic estimate. Ouch. No, just sad. So sad that Nvidia doesn't deserve mocking, things have gone from funny to pathetic.

At this point, unless there's a massive gain in yields on the second hot lot, there might not be enough chips to do a proper bring up and debug. This stunningly bad yield could delay the introduction of the chip, adding to the current pain and bleak roadmap. If there aren't enough 'good' parts from the second hot lot, that might require running another set, adding weeks to the total. Q1? Maybe not.

It is going to be very interesting to see what Nvidia shows off at 'Not Nvision' in a couple of weeks. Will it give the parts to the engineers to work on, or show them off as a PR stunt? We will know soon enough. In any case, the yields as they stand are sub-2%, and the status of the GT300 is far worse than we had ever imagined.S|A

从“NVIDIAはGT300のEngineering sampleを9月に完成させ” ，到“NVIDIA GT300 is an Engineering sample of nine will be completed”，再到“The translation, as we read it, says there were nine good samples that came back from TSMC from the first hot lot”。

google的翻译器还是beta版。认了吧。
居然把NV9月出工程样品最快12月出货给翻译成#…*·（—%（）#%）（#
最后那段英文翻译过来更是…*（#￥—）·（））·—（）# 1.7%悲剧啊！

Edison

1.7% 倒是他自己的 "另一个 source" 打听到的，和 "9" 关系不大。

什么？

g300真实的良率有多少?

看英语太痛苦了

尽管不懂日语，不过凭借其中的汉字，还是能明白一点儿。

300mm晶圆，每片104片的话，gt300难道是300mm2左右的面积？

晶体管数量还是要堆到20亿的，难道gt300打算上高频？

google翻译的？那就对了～

原来老外的狗仔队也这么强！

Edison搞错了吧。。。怎么看翻译错误也不是文章的核心，如果他的料属实 这篇帖子的标题应该改成“NV的悲剧”或者“台积电的悲剧”才对

全文看下来，Charlie从某个渠道得到了GT300芯片良率低到不可置信的地步，416片里面核心只有7片是好的，所以他用了they were so abysmal that we didn't believe it，然后Charlie引用了翻译错误的文章，以为文章里提到了9片样品(汗 还自动增长了2片)。。。。

NVIDIA和AMD在2009年下半年和最新的DirectX 11功能的图形处理器是试图发起。

NVIDIA的GT300是9个工程样品将在今年最快在1月12日至1月开始航运完成。
与此同时，AMD的Radeon高清5800（RV870）成立于5月下旬至9月的出货量为7月10日举行。第一Radeon高清5800和Radeon HD 5870将推出5850两种型号。

AMD公司也已成为双GPU旗舰卡已被2009年第四季度举行。此卡是“铁杉”的是所谓的这款Radeon HD 4850的继任者。 Radeon高清5870X2产品名称将被视为。 Radeon高清5870X2没有透露细节，2GB的配备GDDR5作为输出的DisplayPort，HDMI，DVI和已经表示，。

GT300和RV870信息过去并没有太大变化。如果有元素GT300还是有点不流畅，RV870将于9月22日和10来在该船舶的方向很长的路本月完成。星期天9月10日将在RV870活动，预计将揭示当时的新信息。
硬件新闻电台的这款Radeon HD 5800系列的价格，根据这款Radeon HD 5850是279美元- 299,5870元至379〜399,5870 X2处理器将会成为599美元。

NVIDIA和AMD2009年下半年都打算ronchi做DirectX 11对应的最新GPU。
NVIDIA9月使之完成GT300Engineering sample，最快在今年的12月份大量出货。
另一方面，AMD9月半ronchi做Radeon HD 5800(RV870)，10月预定着出货。Radeon HD 5800首先Radeon HD 5870和5850 2款被投入。AMD2009年第4季度，预定着成为旗舰的Dual-GPU。这个卡由于被称呼"Hemlock"的成为Radeon HD 4870X2继任，产品名称一般认为成为Radeon HD 5870X2。Radeon HD 5870X2详细不明,不过，一般认为装载2GB的GDDR5，作为输出装载DisplayPort, HDMI, DVI。 与过去的信息并不是那么变化关于RV870和GT300有。GT300人还有若干变动的要素,不过，RV870在9月22日ronchi·10月出货的方向相当确定。好象9月10日也有有关RV870的活动。HardwareInfosRadeon HD 5800系列的价格刊载，根据这个成为Radeon HD 5850$279～299，5870$379～399，5870X2$599。
没有和良率有关，还是老新闻
