AMD EPYC Series
Latest Flagship: EPYC 9004 Series (Codename Genoa/Bergamo/Genoa-X)
Architecture: Zen 4 (Genoa, Genoa-X) / Zen 4c (Bergamo)
Previous Flagship (Still Highly Powerful & Common): EPYC 7003 Series (Codename Milan/Milan-X)
Architecture: Zen 3 / Zen 3 with 3D V-Cache
AMD Ryzen Series
Latest Flagship: Ryzen 9000 Series (Codename Granite Ridge)
Architecture: Zen 5
Previous Flagship (Extremely Popular & Powerful): Ryzen 7000 Series (Codename Raphael)
Architecture: Zen 4
EPYC (Genoa/Milan): Strengths lie in multi-core performance, high memory bandwidth/capacity, platform stability, and reliability (ECC). Ideal for server workloads requiring massive parallel processing, high memory demands, and stability.
Ryzen (Zen 5/Zen 4/Zen 3): Strengths include exceptional single-core performance (high clock speeds) and potentially better cost efficiency. Best suited for single-threaded performance-sensitive applications or budget-conscious users seeking high performance.
Which one would be a better choice for a web stack: PHP+nginx+MariaDB?
Ryzen 7000 or Ryzen 9000 or Epyc Turin
Call it a conspiracy theory, but I don't think it actually matters whether its Epyc or Ryzen, at least when we're talking about VPS.
A stronger cpu means a larger room for overselling, i.e. more VMs can be packed on a single host. Because of this, I think performance - generally - will be the same.
Yes, but this could mean that we have greater degradation due to a higher VPS density..
Other that than, Ryzen Single Core it's faster.
Can this have some impact on the VPS performance?
doesn't matter as long as its AMD

Does it mean AMD has risen to the top and is no longer being held down by Intel?
Simple: they both are based on almost the same cores; it's just that with Ryzen AMD goes for speed while with Epyc they go for many cores.
And while I do like the very few Ryzen based VPS I have (because the offer was good, not because it was Ryzen) I'm still amazed that providers use Ryzen for VPS. But I guess there just are many out there who feel they need the fastest of the fastest for their web site, so it's a way to make money for providers ...
I myself would prefer an Epyc based VPS with 4 vCores and plenty memory over a Ryzen based one pretty much always. But I really really like my Ryzen desktop.
Ryzen are better for nodejs and python, epyc for go and rust, php it will not matter much between them, this observation is assuming you have more than 1 core
Ryzen is better for Wordpress websites, that's what I know for sure.
Wordpress websites need single core score so..
Really? AFAIK, both php-fpm and MySQL can and do use multicore.
No, php is definitively single thread.
I think the actual thing with Ryzen VPSes is that a general consumer connects Ryzen with high-end consumer desktop computing. So if a potential customer has to choose between an Epyc or Ryzen VPS (even though performance will be similar due to overselling) they'll still likely choose Ryzen because of this.
I think Epyc multi-core is better if you are selling VMs
Yes, something along those lines.
