I'm lazy, so it's 99% for me. I don't even mess with AMD CPUs; I know they're not exactly the same instruction set as Intel, and more importantly they work with a different (and less mainstream) set of mobos, so I don't want em. If AMD manages to pull more customers their way, that's great, it just means lower Intel premium for me.



That's an interesting take. AMD mobos are no "less mainstream" than Intel ones are... When you choose a CPU you are also choosing a compatible mobo chipset. The companies that make motherboards are mostly the same, so there should be no big difference between those.

Also, while the CPU instruction sets are not exactly equal, the same is true for Intel processors of different generations too. And it doesn't matter one bit... Unless there is a bug in CPU you will never notice the difference, because it is taken care of at the compiler / kernel level.

Intel does have some advantages (and disadvantages too) over AMD, just not those.


I have no idea what you're talking about. Amd and Intel match on the isa in any case you'd see typically. Moreover, Intel is currently using AMDs instruction set. X86_64 was designed my amd and used to be called AMD64


It's never this simple. Their SIMD extensions differ for one, or at least did in the past.


How long ago is that past?

If we are talking about 3D-Now, that is long dead and buried. If we are talking about the latest AVX-whatever, not even Intel is consistent, with different processor families supporting different subsets and applying different clock policies.


AVX-512, which Intel had since 2016 and AMD caught up with supposedly in 2022, is probably what I was thinking of. So, long ago but also not long ago ;)

Yes it was Intel's own spec, so of course they're gonna implement it first, but that's exactly what I mean. This is a recurring dance, and I'll pay a little more for the one that sets the standard. If this weren't a thing, they'd both just be commodity.


What mainstream board company is intel only? Maybe a decade ago on AM3(+) but on AM5/AM5 I haven’t seen a main board partner not offer the same board SKU that works with Intel and AMD.


As an owner of some Sapphire Rapids parts, let me just direct you to: https://edc.intel.com/content/www/us/en/design/products-and-...


To see errata tracked by Intel is a good sign.


Forgot to also mention iGPU and other on-chip accelerators being different and Intel usually having the edge there.
