Here is the memcpy-Benchmark code: #define MEMCPY_SIZE 1048576 // 1MB unsigned int dobenchmark_memcpy() { unsigned char* pDataSrc = (unsigned char*)malloc(sizeof(unsigned char) * MEMCPY_SIZE); unsigned char* pDataDst = &#40...

Meanwhile, I did some memory tests which are quite interesting to look at: memcpy 10GB (10240 times 1MB) P4 2,8GHZ DDR1: 12024ms P4 3,4GHZ DDR2: 6234ms PS3 PPU: 5120ms PS3 SPU: 2736ms PS3 SPU 7 Threads: 781ms

Why is the Cell architecture fast, if at all?

Hi, I did some basic benchmarking on the ps3 against a P4 2,8GHZ both on the PPU and the SPU, and well, my P4 beats the ps3 in every test. Only when using 7 threads or more on the SPU, the ps3 beats my P4, but only with little difference. My Pentium D 3,4G would kill the ps3 again. Some tests: Calcu...
