Now I'm really confused. That just doesn't make any real sense... the two are almost identical! Care to provide a link to benches?3dcgi said:As others have said HT works in Windows 2000, but it runs better with XP.
Sorry, this is false.pcchen said:WinXp Home is a special case. Intel wants the ISVs to use the number of physical CPUs for licensing. Therefore, WinXP Home was designed to support SMP only for HTT. On the other hand, Win2k was not designed this way. So if you use dual HTT CPU with Win2k Pro, you'll see only two CPUs, not four.

Indeed, Win2k Pro only supports up to 2 CPUs. I somehow wonder if it can detect the amount of physical and logical CPUs. In that case, the restriction could be 2 physical CPUs.Saem said:Does the OS actually use them? AFAIK win2k PRO only supports dual cpu configs, unless one of the SPs changed that somewhat.
I don't have any benches to link, but pcchen's explanation is probably accurate. My information came from my brother who is an applications engineer for Intel and while I don't exactly remember our discussion on this I think it had to do with XP having knowledge of HT as pcchen explained.The Baron said:Now I'm really confused.
