Being coy?
The conversation was specifically about AM4 boards and your objection was specifically that “If you want all that extra performance you’re going to need a new mobo anyways.”… that was about AM4.
You continued that by saying “Supported (via a list) and running at full throttle are 2 different things. This is even an issue with current MB chip combinations made for each other. The VRM’s simply aren’t good enough.”
Absolutely zero indication that you had stopped talking specifically about AM4.
Which, again, is a very separate generic statement compared to whether or not a CPU performs as it is advertiesed to according to the respective manufacturers.
AMD isn’t Intel. If you find a bunch of evidence that shows how AMD CPUs performs below the advertised speeds then I’ll consider that a valid concern for AMD users. If you don’t, then don’t assume the same problems Intel users ran into are going to be experienced by AMD users.
Again - we were addressing the recent Ryzen CPUs and them working on the AM4 platform on older motherboards. We were not having a hypothetical theoretical discussion using Intel as evidence.
