RAMspeed SMP
This benchmark tests the system memory (RAM) performance. Learn more via the OpenBenchmarking.org test page.
Stream
This is a benchmark of Stream, the popular system memory (RAM) benchmark. Learn more via the OpenBenchmarking.org test page.
Tinymembench
This benchmark tests the system memory (RAM) performance. Learn more via the OpenBenchmarking.org test page.
MBW
This is a basic/simple memory (RAM) bandwidth benchmark for memory copy operations. Learn more via the OpenBenchmarking.org test page.
t-test1
This is a test of t-test1 for basic memory allocator benchmarks. Note this test profile is currently very basic and the overall time does include the warmup time of the custom t-test1 compilation. Improvements welcome. Learn more via the OpenBenchmarking.org test page.
CacheBench
This is a performance test of CacheBench, which is part of LLCbench. CacheBench is designed to test the memory and cache bandwidth performance Learn more via the OpenBenchmarking.org test page.
