When I installed XP SP3 on my VAIO a few months ago, I remember it said something in recommendations in windows like "Upgrade to a newer 64-bit Windows", but it also said "Upgrade to a newer 32-bit Windows"...

Basically I'm spun out, can my processor do both types or did XP SP3 just bug out on my VAIO?

Is there a way I can found out what my CPU can do in terms of "bits"?

Its always been a pain to really check, and I still have no idea.

Its not really a big deal. You probably won't feel much of a difference between the two versions. Unless you have more then 3Gb of RAM, 32-bit can only detect up to 3. Some programs don't work right under 64-bit.

You can double check what version of Windows XP you have (32 or 64) by right-clicking My Computer and selecting Properties.

I know I'm running Windows 7 on 32-bit, I just wondered if I could also use 64-bit OS's as well, oh well it doesn't matter, I was just curious :]

Get an applcation called CPU-Z here

This is an OS X port but looks the same:

Note the EM64T.

**Skyline34** · 03-20-2009, 01:37 PM

So that means it is 64-bit compatible?

**p0p0** · 03-20-2009, 04:26 PM

It looks like it. It shows EM64T on my 64-bit comp.

If it's 64-bit compatible, and you have like 2gb+ of ramish, and at least 2.2ghz dual core processor, you will notice a humongous difference between the two.

EM64T, an abbreviation for Extended Memory 64 Technology and now known more commonly as Intel 64 or the x64 (that is when including AMD64 too), is a 64-bit superset/extensions that is processed by the CPUs. It is widely used in Intel's processors, including Pentium 4, Pentium D, Pentium Extreme Edition, Celeron D, Xeon, Pentium Dual-Core, and in the Core 2 processors.

Originally codenamed Yamhill, the EM64T, was first "announced" in 2004, when the Intel chairman at the time, Craig Barrett, announced how it was underway. This technology went through quite a bit of name changing, as in the Intel Developer Forum (IDF) it was known as CT (possibly standing for Clackamas Technology, although it is uncertain); soon, it was referred to as the IA-32e and finally in March 2004, it was officially announced as the EM64T. However, in late 2006, Intel began to lessen the use of the name EM64T and began to refer to it as the Intel 64, potentially to rival AMD64.

The EM64T was originally implemented within the E revision (Prescott) of Pentium 4, supported by i915P (Grantsdale) and i925X (Alderwood) chipsets in June 2004. It is assumed that this occurred so as to compete against the Opteron and Athlon 64 lines, also known as the K8 core, from AMD. In Intel, the first processor that adopted the Intel 64 technology was Nocona (codename for a Xeon). Also, considering that the Nocona Xeon was made based off of Pentium 4, Pentium 4 also supports Intel 64 technology, although it was not initially enabled in the Prescott design. Intel officially launched the EM64T in desktop processors in the N0 Stepping Prescott-2M. This revision also included an eXecute Disable (XD) support for Intel 64 and remains included in the current Xeon (codename, Irwindale). The first Intel 64 for the mobile processors is the Merom of Core 2 processor released in July 2006. Unfortunately, none of the previous versions of the mobile processors supports the CPUs.

Real world benefits:
~10% faster in Crysis in XP x64

MASSIVE improvement in Adobe Audition, and other professional audio/video tools when you have more than 4GB RAM.

So that's it then, my CPU does support 32-bit & 64-bit, awesome.
