1. ***处理器
PS3使用 Cell微处理器(Cell Broad Engine),它是由一个3.2 GHz 基于PowerPC处理器架构的64位“电源处理单元”(PPE)控制核心和8个完全一样的向量协处理单元(SPE)运算核心。8个SPE核心中的第7个用于操作系统和安全方面,第8个是备用核心,用以提高工作效率。PlayStation 3游戏机的Cell处理器单精度浮点运算达到204 GFLOPS,双精度浮点运算达到15 GFLOPS。 The PS3 has 256MB of Rambus XDR DRAM, clocked at CPU die speed. As of firmware update 2.01, 32MB of the XDR memory is reserved by the PS3's XrossMediaBar user interface, more XDR memory is required for multiple XMB operations to function at one time .
2. 图形处理单元
图形处理单元, according to Nvidia, 基于英伟达 G70 (过去称为NV47) 架构. The GPU makes use of 256MB GDDR3 RAM clocked at 700 MHz with an effective transmission rate of 1.4 GHz [3] and up to 224MB of the 3.2 GHz XDR main memory via the CPU (480MB max).
3. 配置
至今,为了降低功耗、降低发热、降低噪音PS3进行了多次硬件修改。为此,不得不一步步从90nm到45nm缩小Cell的制程,RSXGPU也是如此。 This in turn results in production savings, lower heat production, lower cooling requirements and quieter running. Since launch, the Cell has had its process shrunk from 90 nm to 45 nm. According to rumors and early Sony plans the RSX GPU has also been shrunk, but that the actual switch would have happened has not been confirmed by Sony or third party disassembly.
PS3 slim更是进一步加强了对功耗的控制,45nm Cell比65nm Cell降低34%的功耗。Further improvements were introduced with the PS3 Slim, with a move to a 45 nm Cell which resulted in a further 34% reduction in power consumption over the 65 nm Cell
