...which is why i prefer AM for hardware longevity.

I am speaking about in general. Newer faster CPUs are something worth being happy about.

This being said there is more to CPUs than raw clock speeds. A major component is IPC uplift. For example if a new cpu has a 20% IPC improvement over an older CPU when they both run at say 3.5Ghz the newer CPU will do things 20% faster. It’s pretty cool stuff.

In the case of the CPUs you mentioned it looks like there was a 16% IPC uplift over last gen and last gen had a 18% uplift over the 5xxx series. I would be happy to have my code compile 16% + 18% faster.

That would be great if that was the case. However you were probably mislead by the title - that IPC increase applies only to 9XXX beasts (Zen 5), not these two AM4 refreshes. At least that's how I understand it.

I was not in fact mislead. I actually went and found that article to help explain the concept of IPC uplift to you.

I was speaking of why new CPUs are a good thing worth being excited by in general. You were the one who said new CPUs aren’t worth being excited about in general.

As a bonus I showed how new CPUs even at the same speed have advantages. This all being said hey if you want to be a downer here go for it.

The new CPUs for AM4 socket. Aren't we talking about AM4 as per post title?

Edit: Probably I should have made it clearer...new new AM5 ones are of course welcome and cool.
