I basically only find this online: https://en.wikipedia.org/wiki/SSE2#CPU_support

But it seems quite incomplete (i.e. where's Intel Core)?

Is there a list of processors that support SSE2? Or how much its used/supported right now?

  • on this forum, you'll find a list (better as in wiki) insanelymac.com/forum/topic/…

  • A list like this would contain hundreds of processors. Questions seeking "lists" are out of scope here at Superuser, I am not aware of any Stack Exchange community, where a question like this would be within scope.

  • why do you need to know that? All x86-64 CPUs support SSE2. And SSE2 support will never disappear in the future due to backward compatibility, unless Intel decided to change to a different architecture

  • @phuclv so only Intel and amd processor? And what about x86?

    you need to check whether the CPU supports SSE2 or not instead of comparing the CPU with a known list. You can't know thousands of the CPUs out there and even more in the future that supports SSE2. And how is ARM relevant here? x86 binaries can't run on ARM

The answer is literally the first 3 sentences at the point you linked in the Wikipedia article:

SSE2 is an extension of the IA-32 architecture, based on the x86 instruction set. Therefore, only x86 processors can include SSE2. The AMD64 architecture supports the IA-32 as a compatibility mode and includes the SSE2 in its specification

This means virtually every modern Intel and AMD CPU supports SSE2.
