Talk:X86-64 microarchitecture levels

Was it really OpenSUSE developers who decided on v2 for 16.0, or was it really SUSE developers, or openSUSE developers? From what I remember of the long Factory mailing list thread, it was SUSE developers who provide the kernel and its infrastructure, who did the deciding, while openSUSE developers simply failed to "step up" to continue 15.6's v1 support.

All those neat tools for checking v level on an x86_64 CPU require access to a bootable computer. Those tools are at best negligible help for anyone shopping for an affordable replacement for a v1, or a (clueless?) seller who won't or can't boot something to run one of those tools to include those details among his product's specifications. In general, websites providing details about various CPUs generally omit the very information required to determine whether 16.0 is supported. I haven't found any as yet. If (a) site(s) with the required detail exists, it/they should be identified.

There is no problem at all when you search for a CPU replacement. All CPUs which you can buy since 2013 (over a decade ago) have v2 support. The CPU generations are described in this wiki and also the source links are provided at the end. No Problem at all when you don't buy a CPU which is a decade old. Hui (talk)

Searching for a PC replacement and a CPU replacement aren't the same thing, and "buying" for some doesn't mean new or freshly maufactured. There may be no way to know which CPU is inside, or when it was made, if it can't be booted before acquisition. I have an i5-660, and goto https://www.intel.com/content/www/us/en/products/sku/43550/intel-core-i5660-processor-4m-cache-3-33-ghz/specifications.html to see it says it's a Clarkdale, but the Wiki doesn't have Clarkdale on it anywhere. The only clue connecting to the Wiki on that Intel page is Q1'10, which is >15 years old, but newer than 2008/Nehalem. Only because I can boot Linux, I know it supports v2. OTOH, I have a big bunch of Core* (Duo, Quad; Wolfdale, Penryn, etc.) CPUs from 2008 & 2009, none of which are Nehalem, and all of which are v1 only. IOW, the terms "Core" and "big" don't go far enough. An explicit explanation that "Core" and "Core2" don't make the cut, while "Core i" does, ought be provided unless and until some better offsite database or guidance can be pointed to. I can deal with this personally, at least WRT Intel products, but I'm sure many with little or no money to spend "shopping" could easily be thwarted from making a suitable choice based on the criteria provided by the Wiki.
