The effect of memory speed on AMD Trinity APUs 1 Attachment(s) In order to find out exactly what the influence of RAM speed is on AMD processors, we put an AMD A10 5800K processor on an ASUS F2A85-V Pro motherboard and ran a number of benchmarks at various memory speeds. The performance differences for 3D benchmarks and games, which really tax the integrated GPU, are significant. In 3DMark 11, DDR3-1866 offers almost a 12% increase in performance. In 3DMark Fire Strike it's almost 18%. In games it's even more, more than 20% in Tomb Raider, almost 25% in BioShock and Dirt and almost 30% in Hitman Absolution. Those significant differences are limited to games, however. In CPU benchmarks like Cinebench and the TechArp x264 video encoding test it's negligible. http://us.hardware.info/reviews/4372...d-trinity-apus |
Cheapest DDR3-1333 at Newegg.com is $18/2gb stick so building an 8gb setup would cost you $72 Cheapest DDR3-1866 kit at Newegg.com is $38/4gb kit (or $19/2gb stick) 8gb system would cost you $76 in short: go for highest rated DDR3 sticks if planning to use the integrated graphics on AMD systems. price difference between 1333 <> 1866 is negligible! |
