Intel Pentium 4 6XX Sequence and 3.73GHz Extreme Edition Processors
64-bit Testing 3ds max 7
Next we ran through our 3D Studio Max tests again but within the Windows XP Pro x64 environment. Again, in these tests we'll can only compare the new P4 6XX series and Extreme Edition CPUs to their Athlon 64 counterparts, since these are the only chips capable of supporting 64-bit extensions.
As you can easily see, 64-bit OS-based performance with this native 32-bit application is just slightly slower than the 32-bit version of Windows XP at this time on either processor architecture from AMD or Intel. Furthermore, the Pentium 4 Extreme Edition and Pentium 4 660 maintain their positions relatively in the performance spread for this test.
