It offers 18 cache and memory benchmarks for i386 and amd64 +machines, though 6 only for alpha ones. There are *mark benchmarks such as +INTmark, FLOATmark, MMXmark and SSEmark. They operate with linear (sequential) +data streams passed through ALU, FPU, MMX and SSE units respectively. +There are also *mem benchmarks such as INTmem, FLOATmem, MMXmem and SSEmem. +These are supposed to illustrate how fast is actual read/write memory +performance. There are also non-temporal versions of MMX and SSE benchmarks. +They have been coded with special instructions to minimise cache pollution on +memory reads and to eliminate it completely on memory writes. In addition, they +operate with a built in aggressive data prefetching algorithm. In some cases, +non-temporal MMXmark and SSEmark can deliver almost 100% of theoretical +bandwidth while reading. + +WWW: http://alasir.com/software/ramspeed/ |
