Vista 32Bit vs 64Bit
Below is a chart demonstrating the performance of 32bit and 64bit applications
The exact same system was used to achieve these results.
The Yellow bars represent the system with 4 gigs of RAM on Vista 32Bit.
The Orange bars represent the system with 8 gigs of RAM on Vista 64Bit
PCMark05, 3DMark06 and 3DmarkVantage are all 32 Bit applications. Running these benchmarks in either the 32bit or 64bit system yielded almost identical results.
PCMarkVantage comes with both 32bit and 64bit versions.
Our tests would indicate that running a 32Bit application under Vista 64Bit and 8 Gigs of RAM does NOT increase performance.
However running a true 64Bit application under Vista64 yields almost 10% extra in performance results.
The above results are based on a P45 Motherboard - 2 Gigs RAM - E8400 CPU - GTX260
