[GPU Computing] GPCBenchmark OpenCL Benchmark
Here is a new rough-and-ready GPU computing tool that comes to us from China. GPCBenchmark is an OpenCL based benchmark that evaluates the performance of OpenCL capable devices with a collection tests: global and local memory bandwidth, single and double precision floating point performance, common mathematics operations (256×256 matrix multiplcation – ouch!), image processing and encryption (SHA-1).
Here are some results. My system: Core i7 960 + GT 240 + GTS 250.
- CPU: 34.752 Million loops / sec.
- GTS 250: 122.666 Million loops / sec.
- GT 240: 81.496 Million loops / sec.
Local memory bandwidth test:
- CPU: 182.966 GB / sec.
- GTS 250: 742.682 GB / sec.
- GT 240: 421.841 GB / sec.
On some tests like single and double precision floating point or common mathematics, I got no results after several minutes.
