clpeak

clpeak is a synthetic micro-benchmark that measures the peak achievable compute performance of your device's GPU and CPU. It runs tight, hand-tuned vector / MAD / MMA loops to expose what the silicon is actually capable of in isolation — raw peak numbers, not real-world workload performance. Backends on Android: Vulkan, OpenCL, and a native CPU backend. Every available backend runs back-to-back on the same device, so you can compare how different compute stacks perform on the very same hardware. What it measures: • Single, half, double and bf16 floating-point compute (GFLOPS) • Integer throughput and INT8 dot-product • Matrix-engine / tensor throughput where supported • Global and cache / local memory bandwidth • Memory latency Source, issues and details: https://github.com/krrishnarraj/clpeak
