[GPU Computing] GPCBenchmark OpenCL Benchmark

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.

SHA-1 test:
– 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.

    I got +- 352 million loops / sec with my hd 4870 512mb/256bits 780/1000MHz, using a Q6600 @2.4GHz at the SHA-1 test!

    On my stock Core i7 860 ram @ 1600Mhz and stock 5850 I got,

    SHA-1 test:
    – CPU: 48.500 Million loops / sec.
    – Cypress: 585.942 Million loops / sec.

    Local memory bandwidth test:
    – CPU: 135.664 GB / sec.
    – Cypress: 237.277 GB / sec.

    I wonder why the GTS250 and GT240 got higher score. The 5850 has more bandwidth, that’s a fact.

    Is it only me, or the website really has disappeared altogether? (Even the chineese version)
