Pressed enter by accident. So I had a Zen+ CPU in my first build during summer 2020. I got a R5 2600 because the 3600 was sold out everywhere I looked (both Amazon and New Egg). By that time it easily ran DDR4-3200 with no issues (bought the RAM for Zen 2). From what I've read about Zen 1, many people couldn't get 3000 MT/s or higher without problems early on and I think people were fine with 2600 or so (looks like Zen 1 officially supported 2666). Either way all this improved months or years after launch. The same should be discovered with Zen 5 as far as overall performance.

I think you meant Zen 2 right? Also it's still early in the life of Zen 5. Wait a few months and it should settle into place and that's when we'll see how it really performs because right now it's just not optimized well enough and new motherboards aren't out yet either. I've heard the original Zen was not very good at launch (mediocre in games/single threaded work but still mostly good multi-threading and good prices) and it took a while before XMP was stable on it. Over time it got better. Zen+ had better stability and memory controller

Ddr 6000 is the sweet spot because not all chips can do 6200 let alone 6400. It's the same io die as Zen4. Some hit 6400 but most don't. The 3 7800X3D's I tested could not run 6200 stable enough. Most of the time it does not even boot. You need very customized settings to get it to boot. Maybe newer bosses can improve it a bit more. But I understand why amd recommendeds 6000.
And about pbo a lot of apps did not benefit and made it less efficient.
I'm very sad to say it because I would have loved to pay for a nice uograde over my 7800X3D. But Zen5 desktop is not that good. It's very good at certain server workloads and it will probably so well there.
But desktop Zen5 has some kind of bottleneck in most applications. Some show what the new arch can do but most do not and some even perform worse.
It's sadly not what we hoped for.
The only hope for gamers is a 9800X3D that can clock higher than the 7800X3D but looking at Zen5 so far I do not expect wonders.
I hope they can fix this scaling issue with Zen6 so am5 can have one good upgrade.
At this point they should release Zen7 on am5 as well since Zen5 did not give us a lot in terms of performance.
AM4 had 3 major uplifts. Zen3, Zen3 and Zen3X3D and one smaller one with Zen+. I don't think AM5 will come close after Zen5's disappointing performance.
