Performance of 64-bit vs. 32-bit Windows Dual Core

Posted by ScuttleMonkey on from the more-bits-about-bits dept.

mikemuch writes "ExtremeTech's Loyd Case has done extensive testing on the same dual-core Athlon X2 4800+ system to explore performance differences between Windows XP Professional x64 and good ole Win32. The biggest hurdle is getting the right drivers. There are a few performance surprises, particularly in 3D games."

    I can only conclude that they made no attempt to use the extra registers.

    Of course they didn't. You think these "ExtremeTech" guys have the slightest clue what a register even is?

    They tested a whole bunch of 32-bit apps on a 64-bit OS. They found that the 64-bit OS was slightly broken in a couple cases. That's about it.
