Hi. I just did a reformat of my system, which has the following specs:
AMD Phenom II X4 925, MSI 785GM-E65 (785G + SB710), 4 x 2GB Apacer DDR3-1333, Sapphire ATI HD5670 1GB, TP-Link TL-WN781N Wifi adapter, WD Green Power 1TB SATA, a couple of LG optical drives, ACBel 610W Power Supply, Windows 7 x64 SP1.
Prior to reformatting, I was using Microsoft's built-in AHCI drivers. I was thinking it's been a while since AMD's AHCI driver issues were publicized and maybe it's about time they finally have good AHCI drivers for my SB710. To measure performance I used PassMark's PerformanceTest 7 64-bit. I once recorded my scores using MS's AHCI drivers, and now compare them with the results with AMD's AHCI drivers (I used the latest driver posted on game.amd.com).
PassMark PerformanceTest - Diskmark
Microsoft AHCI Driver - 536
AMD AHCI Driver - Range from 419 to 519
I wonder why the variance between the test runs are significant. Still, I remember having scores as low as 300+ with AMD's previous AHCI drivers, so I guess this is a huge improvement. However, I notice that games now take noticeably longer to start with AMD's drivers.
Any similar experience with AMD's current AHCI drivers? Thanks.
