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.

Being ignorant about something isn't the same as knowing about it. You apparently don't know enough about CPUs to know that worrying about instruction set differences isn't a real concern, but still want to handwave about it. Likewise, the motherboard comment is also handwaving, unless you can name a single popular motherboard maker that doesn't make motherboards for both AMD and Intel.

If you want to make decisions about tech based on not knowing something, that's fine, but at least make it about things that are arguably actual issues.

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.

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.

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.

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

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.

Well it was long ago that Intel added the extensions I'm thinking of but not long ago that AMD did. AVX-512, which Intel had since 2016 and AMD caught up with supposedly in 2022.

Yes it was Intel's own spec, so of course they're gonna implement it first, but that's exactly what I mean. One is the market leader, and this will be a recurring dance.
