The Race for a New Game Machine: Creating the Chips Inside the XBox 360 and the Playstation 3


by David Shippy (Author), Mickie Phipps (Author)

这是IBM开发部门的主管写的书, 讲的就是PS3跟x360的CPU.

有爱的人可以去看看.

主机比游戏好玩哦~~~~~~~~~~~~~··

There's one company that's getting rich out of every video game system you buy. IBM chips are at the heart of all three home consoles, from Wii to PS3.

While PS3's unique Cell processor is well-known for its supercomputing power, a new book from one of Cell's designers explains how R&D spent on PS3's advanced chip was used in making the Xenon processor for Microsoft's Xbox 360.

Sony approached IBM to create the Cell processor in 2001, with plans to target a Christmas 2005 launch for the PS3. Microsoft approached IBM in 2002, and it appears Sony agreed to let Microsoft not only see early prototypes of Cell, but purchase components as well. "All three of the original partners had agreed that IBM would eventually sell the Cell to other clients. But it does not seem to have occurred to Sony that IBM would sell key parts of the Cell before it was complete and to Sony's primary videogame-console competitor. The result was that Sony's R&D money was spent creating a component for Microsoft to use against it," the Wall Street Journal book review summarizes.

While the end result for Cell and Xenon are both quite different, it's ironic to think that Sony may have inadvertently aided its primary competitor. Of course, console success stories are always based on quizzacle corporate decisions. Let's not forget that Sony's first console, PlayStation, was originally a collaboration with Nintendo to make an extension to the SNES.

以下仅是翻译

------------------------------------

01年Sony, Toshiba和IBM联合开始研发Cell, 02年MS和IBM联合研发Xenon.

后来, Xenon还是部分参考了Cell, 因为sony,Toshiba都同意IBM最终将Cell处理器卖给别的客户, 但是Sony要求IBM在Cell开发完全之前不能卖, 而且附加了条件, 要去IBM不能将Cell卖给Sony游戏机的竞争对手.

但是Sony同意MS参考了Cell的原型处理器, 并且还卖给了MS部分component.

虽然最终Xenon和Cell区别很大, 但是讽刺的是Sony还是帮助了自己的主要竞争对手MS...

当然了, 我们不要忘了, 当年Sony的Playstation, 本来是要和任天堂合作制作Super Nintendo Entertainment System的..后来出现分歧后才有了Playstation

去年的火星帖，大意是360的3核CPU都是CELL的主处理器

不是, 360的Xenon是参考了Cell原型而已

但是最终产品是截然不同的.

性能也差不多.

Sony原计划也是05年圣诞发售Ps3的, 但是倒霉出问题了, 于是PS3延期06年底发售.

X360于是就早发售了一年.

.......

不清楚，我只知道CELL是IBM的主推CPU，Xenon没怎么了解。
一个传统的多核，一个是***性的....

Cell的PPU弱这,但是SPU很强.
但是CELL的SPU执行多分支的代码时性能会大幅下降.要获得最大性能就需要把执行过程尽可能的缩短,简单,减少分支判断.同样的东西在360上开发,程序的结构不需要有太大的变化.而在PS3上,为了适应Cell的特性,需要将那些相对冗长,复杂的过程尽量分治成简单,线性执行的过程,这是比较复杂的事情.

另, PS3的内存和显存是分开了, 分别都是256MB, 而X360是cpu和显卡share共同的512MB内存, 这也导致主机之间的差异.
