Geekbench is an essential cross-platform benchmark for Windows, Linux, and Android that you can use to measure your PC's processor and RAM performance.
You can access multi-threaded benchmarks that run in single-threaded and multi-threaded modes, letting you see the performance increase multiple cores (or multiple processors) bring to your system. It is available in 32-bit and 64-bit versions, so you can run both versions on a 64-bit operating system and see the overall increase 64-bit applications bring to your system.
Geekbench features benchmarks that utilize SIMD instructions (Altivec and SSE), allowing you to see performance increases SIMD-aware applications bring to your system. It can also be used in both Universal and Rosetta versions (Mac OS X). Run the Rosetta version on your Intel-based Mac to see how quickly it runs PowerPC applications or discover the performance advantages Universal apps bring.
