ביצועים של יישומי 32 ביט תחת מערכת הפעלה של 64 ביט:
In other words, the use of
64-bit operating system with the CPUs
based on x86-64 architecture doesn’t have any negative influence
on the performance in old 32-bit applications.
So, now the performance of our systems in 3D applications in
Windows XP Professional x64 Edition is comparable with what
we see in the same tasks in a regular 32-bit OS.
However, I would still like to stress that the performance of the
tested Athlon 64 and Pentium 4 processors in the 64-bit Windows
version is somewhat lower than the results obtained in 32-bit operating
system. Although, this performance difference doesn’t exceed 5%
that is why I decided to disregard it for now.

כלומר מעבר של יישום מ 32 ביט ל 64 ביט יכול להניב שיפור עצום, סדר גודל של 50%!
כמובן שתלוי באיזה סוג ל יישום מדובר. זאת המחשה טובה ליכולת של חומרת ה AMD64
בשילוב עם מערכת הפעלה ויישום של 64 ביט.
Again we witness a significant performance boost when we use the execution code optimized for 64-bit extensions of AMD64 and EM64T. In this case the performance increase by the CPU with AMD64 technology made 55%, while in case of a CPU with
Intel EM64T technology the performance in 64-bit mode grew up by 40%. In other words, we once again see that AMD’s implementation of 64-bit extensions appeared more efficient than 64-bit extensions for x86 architecture from Intel.
מסקנה
However, we have to state that the entire infrastructure necessary for successful transition to 64-bit era is almost ready. The operating system ready to be released works just fine, even though it is still an RC1 revision. Most drivers have also been almost finalized by now. All we can do now is wait until Windows XP Professional x64 Edition comes out, which should happen in H1 2005
