In testing of OpenBenchmarking.org and preparations for the release of Phoronix Test Suite 3.0-Iveland at the end of February from SCALE, a lot of benchmarks have been happening to test the various analytical features and other new capabilities of this open benchmarking platform. In fact, it is really an overwhelming amount of benchmarks; the power capacity in my office is maxed out as benchmark after benchmark and system after system there is all sorts of test scenarios being looked upon. The benchmarks coming out on Phoronix.com over the past two months have just been barely scratching the surface of what has been going into the OpenBenchmarking.org system. Recently a lot of OpenCL compute benchmarks were pumped in, and since we have only published a few OpenCL Linux benchmarks -- OpenCL on Linux vs. Mac OS X and OpenCL NVIDIA vs. ATI on Linux -- here's some more in this article.
This article encloses a number of OpenCL results for the NVIDIA GeForce 8600GT 512MB, 8800GT 256MB, 9500GT 1024MB, 9800GT 512MB, 9800GTX 512MB, GT 220 1024MB, GT 240 512MB, and GTX 460 768MB graphics cards. These OpenCL tests on the various generations of NVIDIA graphics processors were tested on a system bearing an Intel Core i5 750 CPU, an ECS P55H-A motherboard, 4GB of system memory, and a 500GB Western Digital SATA HDD. The software portion consisted of Ubuntu 10.10 with the Linux 2.6.35 kernel, GNOME 2.32.0, X.Org Server 1.9.0, NVIDIA 260.19.29 binary driver with OpenCL 1.1 / OpenGL 3.3 support, GCC 4.4.5, and an EXT4 file-system.
From Phoronix Test Suite 3.0 we used the JuliaGPU, MandelGPU, SmallPT GPU, MandelbulbGPU, and GluxMark benchmarks. Here are all of these OpenCL results from eight of NVIDIA's graphics cards for your reference.
