Perfomrance comparison of GPU boards from AMD as of Oct 2009
We have tested GPU borads from AMD with our test program implementing a simple N2 force evaluation algorithm. A nominal performacne of each board is shown in the following table.
| board | arch | clock | memory | No.SC | SPmul-add | DPadd | DPmul | BW |
| HD4850 | RV770 | 625 MHz | DDR3 662 MHz 256bit | 800 | 1040 GFLOPS | 208 GFLOPS | 104 GFLOPS | 63.6 GB/sec |
| HD4870 | RV770 | 750 MHz | DDR5 900 MHz 256bit | 800 | 1200 GFLOPS | 240 GFLOPS | 120 GFLOPS | 115.2 GB/sec |
| HD4770 | RV740 | 750 MHz | DDR5 800 MHz 128bit | 640 | 960 GFLOPS | 192 GFLOPS | 96 GFLOPS | 51.2 GB/sec |
| HD5870 | RV870 | 850 MHz | DDR5 1.2 GHz 256bit | 1600 | 2720 GFLOPS | 544 GFLOPS | 272 GFLOPS | 153.6 GB/sec |
The program is basically same to out demo program posted http://galaxy.u-aizu.ac.jp/trac/note/wiki/Astronomical_Many_Body_Simulations_On_RV770#DemoProgram here
