CELL 排除协处理器部分 那个单独的完整核心 和360设计是一样的.... 所以微软说整数是PS3的整整三倍 原因 ...

CELL是靠SPU的 单单去比较一个物理核心毫无意义 拿执行Deferred Shading来说 这些SPU在过程中受PS3的GPU也就是RSX控制 由RSX来发起渲染过程同时执行包括SSAO在内的其他全部工作 而所有涉及Deferred Shading的后效部分则完全交由SPU来完成


还有PS3 支援的HDR格式 是FP16 而360仅能支援到FP10 孰优孰劣一目了然

精神日本人

cell是不是已经死了，谁能回答我

我什么时候说 这些关于浮点运算的问题 360比PS3强了 我说的是中文吧？ 哥们 听的懂吧？ CELL 浮点更强 可以辅助GPU实现一系列效果 但是只能说CELL 是个出色的副显卡 就本职工作 CPU 该干的事情 他一个核心 干不过360三个核心的.....同样的游戏 360 能做承受更多的AI寻径、硬件资源的分配、弹道运算

看来很老旧啊，这颗CPU。

The PowerPC 740 and 750 (codename Arthur)[2] were introduced in late 1997 as an evolutionary replacement for the PowerPC 603e. Enhancements included a faster 60x system bus (66 MHz), larger L1 caches (32 KB instruction and 32 KB data), a second integer unit, an enhanced floating point unit, and higher core frequency. The 750 had support for an optional 256, 512 or 1024 KB external unified L2 cache. The cache controller and cache tags are on-die. The cache was accessed via a dedicated 64-bit bus.

The 740 and 750 added dynamic branch prediction and a 64-entry branch target instruction cache (BTIC). Dynamic branch prediction uses the recorded outcome of a branch stored in a 512-entry by 2-bit branch history table (BHT) to predict its outcome. The BTIC caches the first two instructions at a branch target.

The 740/750 models had 6.35 million transistors and was initially manufactured by IBM and Motorola in an aluminium based fabrication process. The die measured 67 mm2 at 0.26 μm and it reached speeds of up to 366 MHz while consuming 7.3 W.

In 1999, IBM fabricated versions in a 0.20 μm process with copper interconnects, which increased the frequency up to 500 MHz and decreased power consumption to 6 W and the die size to 40 mm2.

The 740 slightly outperformed the Pentium II while consuming far less power and with a smaller die. The off-die L2 cache of the 750 increased performance by approximately 30% in most situations. The design was so successful that it quickly surpassed the PowerPC 604e in integer performance, causing a planned 604 successor to be scrapped.

The PowerPC 740 is completely pin compatible with the older 603, allowing upgrades to the PowerBook 1400, 2400, and even a prototype PowerBook 500/G3. The 750 with its L2 cache bus required more pins and thus a different package, a 360-pin ball grid array (BGA).

The PowerPC 750 was used in many computers from Apple, including the original iMac.

难道现在没人用cell，自己玩非主流结果大家都不鸟让它自身自灭，市场是检验一切的标准，吹了半天了结果彻底被时代淘汰

呵呵

真yin人

硬件***随便问问，这个性能和PS3还有360比有啥优势有啥劣势？

那我简单点和你说吧 SPU 不是一个完整的核心 很多完整核心CPU的运算它们不能做 它们的功能是辅助显卡运算 OK？ 所以这点上胜于360 OK? 但是360 有三个完整核心 纯粹说CPU干的那些事情 PS3不如360  OK？ 主要问题是SPU 的工作显卡都能做 那个单独的核心的工作 显卡不能做

原来如此。

Gekko
Main article: Gekko (microprocessor)

Gekko is the custom central processor for the Nintendo GameCube game console. It is based on a PowerPC 750CXe and adds about 50 new instructions as well as a modified FPU capable of some SIMD functionality. It has 256 KiB of on die L2 cache, operates at 485 MHz with a 162 MHz memory bus, is fabricated by IBM on a 180 nm process. The die is 43 mm2 large.

Broadway
This Broadway processor is manufactured in East Fishkill, NY, but it's packaged in IBM's plant in Canada, hence the text on the metal cover.
Main article: Broadway (microprocessor)

The CPU in Nintendo Wii is virtually identical to the 750CL but it runs at 729 MHz, a frequency not supported by stock 750CL. It measures only 4.2 x 4.5 mm (18.9 mm2). This is smaller than half the size of the "Gekko" microprocessor (43 mm2) incorporated in the GameCube at its first release

那请你找一个06年之前比CELL更牛逼的民用CPU出来

CELL 强在意SPU上 可是SPU是用来纯粹浮点的... 真只比CPU的 AI寻径、硬件资源的分配、弹道计算 神马的 CELL 不强 是随便找个多核心 中端货就搞定它了
