Test System Setup
Processor: AMD Athlon 64 X2 3800+ AM2
Memory: 2x 1GB DDR2-1066 Corsair (Supplied by Corsair)
Hard Disk: 500GB Seagate 7200.9 (Supplied by Seagate)
Graphics Card: nVidia GeForce 7800GT (SLI and non-SLI)
Cooling: Gigabyte NeonK8 (Supplied by Gigabyte)
Operating System: Microsoft Windows XP Professional SP2
Drivers: nForce Platform Driver 9.16, nVidia ForceWare 91.31 and DX9c
In our tests today we will be determining which nForce 500 series chipset is the fastest. Does the 590SLI have any advantages using single graphics over the rest of the pack? Does it perform better in SLI than the 570SLI in SLI?
We used DDR2-800 for stock clock speeds and ran the memory at 1:1 when we overclocked to get the highest FSB performance as possible. We kept the CPU speed as close to stock as possible to see just what happens.
Each test platform is tested at stock speed and overclocked - the 590SLI platform CPU was running at 2.25GHz (6 x 375MHz FSB), 570SLI and 570 Ultra platforms at 2.11GHz (6 x 352MHz FSB) and the 550 platform at 2.25GHz (10 x 225MHz FSB). Since the memory was running at 1:1 for the purpose of our overclocking tests, the higher FSB will result in greater performance. It's not a demonstration of the highest CPU clock speed but maximum FSB obtainable. When running SLI mode on 590SLI and 570SLI, it was running SLI and overclocked at the same time.

SiSoft Sandra (System ANalyser, Diagnostic and Reporting Assistant) is a synthetic Windows benchmark that features different tests used to evaluate different PC subsystems.
At stock speeds the memory bandwidth is all equal across the board. When overclocked we see that the NF590SLI with its higher FSB manages a slightly higher overall score.
