Is a PENTIUM-D actually 64-bit?

Question

I have a Pentium D 3.0GHz, and of course the D means Dual Core, and when I go to my Device manager it shows me that I have TWO 3.0 GHz processors...

So what I really want to know, is if I buy VISTA PREMIUM, can I run the 64-bit version???????????

Answer 1

no, a Pentium D is actually a 32bit processor. more important is if it has the instruction set EM64T implemented, this makes it capable to run 64bit applications.

as you can see on the following site, all Pentium D processors have the EM64T instruction set implemented, even the older 8xx series.
yes, you can run the 64bit version of Windows Vista.

Answer 2

Intel D processors are virtually have two CPU's, but not physically. The 64bit of Win XP works with if by always doesn't give much difference from solo CPU. Intel Dual Core processors have physically 2 CPUs but with less speed. Go for Dual core or AMD 64 CPUs.

Answer 3

yes pentium d is 64 bit

Intel® EM64T requires a computer system with a processor, chipset, BIOS, operating system, device drivers and applications enabled for Intel EM64T. Processor will not operate (including 32-bit operation) without an Intel EM64T-enabled BIOS.

You just have to make sure you have a 64-bit complaint motherboard, look in your motherboard manual or call the company that you bought it from and ask. My best guess is that you probaly do. goodluck on your 64 bit OS
