cpuwhat is a Nim library for providing utilities for advanced CPU operations. Features (and planned features) include:

• x86 Support
• ARM Support
• Querying CPU Name
• Querying CPU Vendor + Microarchitecture
• Querying CPU Cache Topology
• Testing Presence of CPU Instruction Set Extensions
• (WIP) Compiler Intrinsics (currently supporting MMX, SSE 1-3)

Query Example

import cpuwhat

echo(cpuName())
echo("has SSE2:     ", hasSSE2())
echo("has AVX512BW: ", hasAVX512BW())

Intrinsics Example

import cpuwhat / intrinsics / sse

let zero = mm_setzero_ps()
