How it works

BenchD runs intensive WebAssembly (WASM) kernels directly in your browser. The final score is a weighted average of individual tests, scaled using log1p(x) to reward performance gains while preventing numerical explosion.

FP32/64: 30% (Floating Point math)
SIMD/Int: 20% (Vectorization & Logic)
Memory: 20% (WASM memory throughput)
Latency: 10% (32KB to 64MB random walks)
Multi-core: 10% (Scaling efficiency)
Advanced: 10% (Branch, Crypto, LZ77)

*If a test fails on your hardware, its weight is automatically redistributed to ensure a fair overall score.
