Windows tells me that I have a 64-bit processor:

However, checking in the Device Manager it says that my processor is 32 bit:

Why is that?

(I also notice that I have two duplicate processors?)

    it's a 64-bit processor. What makes you believe its not? ark.intel.com/content/www/us/en/ark/products/42809/… most modern Intel processors are of the x86 family with support for 64-bit instructions. Windows shows each processor for each core

  • @Ramhound "You are aware all 64-bit processors are just 64-bit x86 processors, right?" No, this is new to me. I have thought x86 is just another way to say 32-bit (of course until now that I learn something new). Many installation list their 32-bit versions as x86

  • @Ramhound Just to clarify, all 64-bit modern Intel processors are x86. There are 64-bit processors which are not x86.

    @Ooker x86 describes an instruction set (what commands are available for programmers to send to the CPU). There is a 64-bit extension to the x86 architecture called x86_64. A lot of people simply say "x86" to mean 32-bit nowadays, but that's not technically accurate - it's just that most software is compiled for the x86 architecture. There are other architectures in both 32 and 64-bit, such as ARM.

Your processor is a 64-bit processor.

I'm not sure why it's showing up as x86 in your device manager (as opposed to x86_64), but it's mostly likely because your 32-bit installation of Windows will use the x86 instruction set and thus treat your 64-bit processor as if it was a 32-bit processor.

The two "duplicate" CPUs are actually the two physical cores on the CPU - it is a dual-core processor.
