Different Experience index between Win 7 32 bit and Win 7 64 bit RRS feed

  • Question

  • Asus P6t DELUXE motherboard Core I7 920 running at 4.0 Ghz 3Gb ddr3 installed 5820 ATI Radeon Boot disk = 60Gb SSD Windows Experience Index on 32bit Win 7 Retail: Processor - 7.6 Memory - 7.9 2D Graphics - 7.8 3D Graphics - 7.8 HDD - 7.1 Windows Experience Index on 64bit Win 7 Retail: (rebuilt machine) Processor - 7.7 Memory - 5.9 2D Graphics - 7.8 3D Graphics - 7.8 HDD - 6.7 I ran 3dmark vantage and pcmark vantage on both builds and the results were similar to each other. Why does the Win Experience rating differ so badly in the Memory area?

  • I'm not sure what my guess would be it's due to the the amount of memory each operating system can access.  32 bit windows 7 can only access 3.5 GB of memory while 64 bit systems can access much more.  The difference in performance numbers is probably caused because the amount of memory you have and its speed is compared to one of optimal for that system.  In your case you are much closer to optimal for a 32 bit system and you are for a 64 bit one.

  • In my opinion, this kind of behavior is related to different algorithm and hardware landscape for 32bit and 64bit architectures in the real world. The scores are relative. There is no need to compare one measure to another. For more inforamation about Windwos Experience Index in Windows 7, please refer to the following website:
