45nm工艺 八核心 32线程 IBM规划Power 7

在Power6发布一年多之后，IBM又开始规划下一代Power7了，无论生产工艺、核心数量、浮点性能都会大有提升。 最新的IBM内部文档显示，Power7将升级为45nm工艺和八核心，每核心四线程，且两颗构成一个芯片模块，即每模块16核心、64线程。IBM称，Power7每核心性能32GFlops，是现在Power6的两倍。

不过在Power6频率达到4.7GHz之后，Power7并不会迅速突破5GHz大关，反而会有所降低。根据文档，IBM将在2010年拿出4.0GHz的Power7，是否还有更高频率版本尚不清楚。

IBM将为客户提供2U Power7系统，内有四个双芯片模块，共计64个核心、256线程，最多支持128GB内存，浮点性能可达2TFlops。

power6 595已经到5G了。你的文档是ibm官方的吗，玩sun的不要在这种坛子里面乱说话。

说真的.我不大相信LZ的数字.:$

8core封装我不相信，说4core我信

power7还很远的事，把power6玩熟了先

可能也就是后年吧～;P

那可不一定，roadmap可能会延期。

怎么像是SUN说的？;P ;P ;P ;P

IBM将在2010年拿出4.0GHz的Power7

先声明一下，我不是玩SUN的！
非官方，要证实消息，恐怕得一年后！
IBM Power 7 – Eight cores to rock your world
The 4 cores that today's processors offer are a far cry from the single cores that we were so accustomed to some years ago. IBM on the other hand is developing the Power7 chip, which not only has 4 cores but also adds in four extra. The eight-core Power7 is being arranged in dual-chip modules. So, that's 16-cores per module. As IBM tells it, each core will show 32 gigaflops of performance, bringing each chip to 256 gigaflops. Just on the gigaflop basis, that makes Power7 twice as fast per core as today's dual-core Power6 chips, although the actual clock rate on the Power7 chips should be well below the 5.0GHz Power6 speed demon. IBM will ship Power7 at 4.0GHz in 2010 on a 45nm process. This system, funded by a $208m grant and meant to go up at the University of Illinois in 2011, will be the most massive machine ever created. IBM is also working on a 10 petaflop system (peak) comprised of 38,900 eight-core Power7 chips with each chip running at 4.0GHz. This monster will have an astonishing 620TB of memory and 5PB/s of memory bandwidth. IBM will rely on a 1.30PB/s interconnect to link the systems and will feed them with 26PB of storage. IBM will offer an Exabyte of archival storage just incase.

这玩意没有正式发布，很难预料。

一起期待...

还没有机会玩过Power6,
