RAMspeed is a command line utility to measure cache and memory performance of
computer systems. 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.
