AMD Spreads Propaganda, Ex-Employee Speaks OutWritten by Sam (Insideris) on October 13, 2011

Launches a man with a shovel.
Back in old days, AMD has issued fake Barcelona CPU benchmark results to lure in some buyers. As we know, it did not turn out well for them.
Well, few years later and the history repeats itself, just check this AMD FX promotional video below:


Now, we did some digging and found out quite few interesting things. Here is a quote from the AMD ex employee himself, who posted few comments about the whole situation some time ago:

On paper bulldozer is a lovely chip. Bulldozer was on the drawing board (people were even working on it) even back when I was there. All I can say is that by the time you see silicon for sale, it will be a lot less impressive, both in its own terms and when compared to what Intel will be offering. (Because I have no faith AMD knows how to actually design chips anymore). I don’t really want to reveal what I know about Bulldozer from my time at AMD.

What did happen is that management decided there SHOULD BE such cross-engineering ,which meant we had to stop hand-crafting our CPU designs and switch to an SoC design style. This results in giving up a lot of performance, chip area, and efficiency. The reason DEC Alphas were always much faster than anything else is they designed each transistor by hand. Intel and AMD had always done so at least for the critical parts of the chip. That changed before I left – they started to rely on synthesis tools, automatic place and route tools, etc. I had been in charge of our design flow in the years before I left, and I had tested these tools by asking the companies who sold them to design blocks (adders, multipliers, etc.) using their tools. I let them take as long as they wanted. They always came back to me with designs that were 20% bigger, and 20% slower than our hand-crafted designs, and which suffered from electromigration and other problems.
That is now how AMD designs chips. I’m sure it will turn out well for them [/sarcasm]

BTW, you ask how AMD could have competed? Well, for one thing, the could have leveraged K8 and the K8 team’s success and design techniques instead of wasting years of time on a project that eventually got cancelled using people that had never achieved any success. It took Intel years to come out with Nehalem, and AMD could have been so far ahead by that point that they’d have enough money in the bank that they wouldn’t have to accept a low-ball settlement offer in the antitrust suit and they wouldn’t have to sell off their fabs.

Gives a totally different perspective on why Bulldozer failed, doesn’t?
Stay tuned.

这点没错，amd唯一象点样子的东西还是从DEC来的，amd自己搞的东西几乎都是垃圾

K6是来自收购的NexGen   K7以后的构架来源于DEC的Alpha,K8 K10修修补补...

94年的K5不知道算不算是AMD独立开发的，我当年买过一块K5 PR90和联讯主板

主要就是便宜...

全世界挖坟党们，行动起来！
曾几何时，按摩店公布了假成绩试图忽悠人们购买巴塞罗那，我们都知道，他们可耻地失败鸟。历史在几年后重演，请看下面的FX 宣传视频：


现在， 本蛋疼星人挖了一通坟，找到了一点有趣的东西，以下是一位有良心的按摩店前雇员在一段时间前发布的历史真相：
在纸面上推土机确实牛逼闪闪.哥还在按摩店打拼的日子里，推土机就在白板上了（甚至有人真的在上面工作）。现在哥能告诉大家的就是当你看到实际上市的芯片的时候，它就没那么牛逼了，不管是和它自己的宣传还是和INTEL的竞争产品相比（因为我不相信AMD 还有能力设计芯片）哥真的不想透露哥了解到的关于推土机的残酷现实
管理层决定应该有交叉工程，也就是说我们要放弃手工优化CPU，换到SoC（片上系统）设计模式，这意味着我们要牺牲大把性能、芯片面积、和能效。DEC Alpha 总是比同期对手牛逼的原因是他们每个管子都手工设计，Intel和AMD 至少对芯片的关键部分这么做，不过在哥逃离AMD以前，一切都变了——他们开始依赖合成器、自动布线工具等等。哥好歹也当了设计流程大哥好多年，还不知道那班卖IC设计工具的是什么玩意，不管给他们多少时间，做个加法器都能多出20%的面积，慢下20%的速度，还动不动就卖电子迁移之类萌。而AMD现在就这样设计芯片，至于你信不信他们能做好，哥反正是信了。
另外，你们问哥按摩店怎么才能雄起？哥觉得，把K8及其团队的成功和设计技术充分利用起来而不是在一个由一帮从来没牛逼的人进行的最终会取消的SX项目虚度年华。Intel用了好几年才拿出Nehalem,按摩店要这么玩，当时早就腰包鼓鼓，可以拿到更好的反垄断青春损失费，更不用卖厂了。

K5有2个版本，老的是486马甲，新的是Nx586,K6是Nx686

桑德斯手下的AMD早就不见了

486马甲的那个不叫K5，叫5x86，当年不少js当586在卖——或者说，这个才是AMD和Cyrix的本意？

5x86是Socket3的。
K5有标称PR和实际频率相同和 PR高于实际频率两种，貌似后面一种是Nx586

NX586加上FPU就是K6了，K5全系列都是标PR的。

即便是NVIDIA和INTEL得人也承认，撇开又是相当无脑的低级错误不谈，AMD的PPT整体制作质量属于极其上乘的。甚至在某些乏味的开发布会上可以提神醒脑~

AMD is already dead...
when I got job offer from AMD, the stock price was $35.
when I joined in AMD, the stock price was $17.
when I quit from AMD, the stock price was $8.
now AMD stock is only $5.

和股票价格没有关系，桑德斯离开后就堕落了～～～～～～恰恰相反我认为amd活的很好

早在旧时代，AMD已发出假巴塞罗那CPU基准测试结果，以吸引一些购房者。正如我们所知，没有变成他们。
好了，几年后，历史重演，只是检查这个AMD FX宣传视频下面：


现在，我们做了一些挖掘和发现，相当一些有趣的东西。这里是报价AMD前雇员自己，谁发布前一段时间对整个形势的几点意见：


在纸面上，推土机是一个可爱的芯片。推土机绘图板（人甚至在它的工作），甚至还当我在那里。我只能说是的时候，你看到出售的硅，它会是少了很多令人印象深刻的，无论是在其自身的条件相比，英特尔将提供，。 （因为我没有信仰的AMD知道如何设计芯片了）。我真的不想透露我的时间，我知道推土机在AMD。


没有发生的是，管理层决定应该有这种跨工程，这意味着我们不得不停止手工编写我们的CPU设计，并切换到SoC设计风格。在放弃了很多的性能，芯片面积和效率，这样的结果。 DEC的阿尔法总是速度远远超过其他任何原因，是他们设计的每个晶体管。英特尔和AMD一直这样做，至少在芯片的关键部位。改变在我离开之前 - 他们开始依靠综合工具，自动放置和布线工具等，在未来几年我一直在负责我们的设计流程，在我离开之前，我测试过这些工具，通过询问谁卖的公司他们设计块（加法器，乘法器等），使用他们的工具。我让他们走，只要他们想。他们总是回来给我的设计，20％和20％，比我们手工制作的设计慢，并从电和其他问题遭受。
这是目前AMD公司设计的芯片。我相信它会变成为他们[/嘲讽]


顺便说一句，你问AMD如何能有竞争吗？那么，对于一件事，可以有杠杆的K8的K8团队的成功，而不是浪费几年的时间，最终得到了使用，从来没有取得任何成功的人取消的项目设计技术。花与Nehalem的英特尔未来几年，AMD可能有如此超前​​，他们会在银行有足够的钱，他们就不会接受低球和解要约的反垄断诉讼，这一点他们也不会卖掉自己的工厂。


给出了一个推土机失败的原因完全不同的角度，不？
敬请关注。

这个给予希望的产品表现比intel的SB差距是大点。暂时没兴趣升级了。
