Microsoft has already spoken on v3, that is why Windows 11 requires Gen 8 I3, i5 and i7 and newer.

The push for raising the x86_64 baseline for RHEL and SLE came from the CPU vendors.
The above statement is not true, at least as far as SUSE is concerned.
That's what triggered the creation of the x86_64 subarch variants (-v1, -v2, -v3). From discussions I've had with people familiar with the matter, they have been pressuring their commercial Linux vendor partners to raise the baseline for a few years now.
For what is worth, I have been part of most of discussions between AMD and SUSE for the last eight years, I would have noticed and been asked to comment if AMD ever raised this. They never have. I repeat: they never have. In fact it was me personally who brought this to their attention after we had the huge thread about this in summer and their response was "do whatever you think will is best." I am not aware of anybody from Intel attempting anything similar either and again if there was concentrated effort I would. The fact is that -v3 baseline means better floating point performance out of the box. That is why many think it is the right choice for a new product that will be deployed almost exclusively on new hardware. No need to invent conspiracy theories to explain what is happening. Martin
