MicroBenchX

Micro benchmarks CPU/GPU.

Basic IPC Tests

Assembler code is based on the great work by Nemes: https://git.nemez.net/nemes/ipc-tests. The code is not comparable because it was modified!

These tests do not represent the real world performance of a CPU. In practice the performance depends on branch prediction, caching and other things like out-of-order executions.

It is very important to set a fixed clock speed for the IPC tests. Disable all turbos, sleep states and AVX offsets. Set "High performance" power plan.

Core-to-Core Latency Test

Measuring inter-core latencies based on Clammicrobench: https://github.com/clamchowder/Microbenchmarks/tree/master/CoherencyLatency

It is recommended to set a high priority for the process in the task manager. Close all other applications.
