Best For WordPress: AMD Ryzen 7700 vs 7950x3D

Hi,
Looking to buy a dedicated server from Hetzner to host around 20 WordPress websites.
I know in theory, Ryzen 9 7950x3D is faster than Ryzen 7 7700.
But 7950x3D has the new split/hybrid cores feature, with a mix of 8 3D V-Cache cores + 8 performance cores.
So in "real world" usage for PHP applications, like WordPress were single CPU thread speed important, what CPU do you think will have better performance?
Thanks
Best CPU for WordPress (fast single thread)?

None. Go for cax line or simple vps. More scalable solution and more feature packed including snapshots and backups.
Thanks for the advice. But not interested in using ARM based CPU and also do not need the extra features like backups.
Just looking for the fastest dedicated server to host my WordPress websites.
AX52 should be enough for you, I don't think you have that huge traffic to load 7950X3D.
Performance in single thread it's very much similar to lower model of CPU (7700).

split 20 Wordpress sites across 2x Ryzen 7700
But really depends on your Wordpress sites and what they're doing and it they can fully leverage static HTML caching or if they're logged in member type sites which can't leverage static HTML caching and need more PHP grunt power.
PHP performance on CAX line is way worse than CPX line. Not sure why you recommend it, this CPU performs good just in Geekbench.
So what's the use case of CAX line? Good for Nginx or MySQL?
I'd say nginx performs better in CAX. Didn't really benchmark MySQL, but I'll try it out (I think disk is more important here perhaps?). And I'll try some simple go/node/python http stuff.
Use Phoronix Test Suite
nothing beats Ryzen for the price and power consumption.
I'd say M1 is better having experienced both in a laptop format.
(Haven't had hands on experience with M2s)
Did some test, ARM is a big win. for single core, it is ~1.2~1.6 times faster for most tasks and 2 times faster in some tests. For the same price (2 ARM cores vs 1 x86 core), the whole thing 2 ~ 3 times faster.
Better than AMD for PHP/Nginx/MySQL? That's amazing!
In what test did you get anywhere near "3x faster" and what instances are you even comparing?
CPX11 PHPBench 639535 points
CAX21 PHPBench 538642 points
Cores in CAX are way slower, in some edge cases even 10x slower (SVT-AV1).
Nginx is scaling well on CAX, but Redis is faster on CPX, so you'll see that ARM speed per dollar advantage on cached JSON responses, on anything else you're limited by IO. But it never reaches even 2x, so please tell me where you saw 3x.
2x more RAM and 2x more storage for same price is the real deal here, this ARM cpu itself is worse for pretty much anything except things that can be done in parallel like batch processing (but not encoding, every important library performs bad on ARM), compilation...
for CI/CD, websites that can be cached so CPU won't work that much its a great deal. But its not great deal in terms of computing power, I dunno where you saw 3x performance advantage, really curious.
2 and up to 3 times better? Where do you got this data / benchmarks from...? As @AXYZE already benched, the PHPBench, AMD won there. I also have some benchmarks. You can take a look and make conclusion. Based on my little benchmarks, i don't think ARM has a BIG WINS as you said.

Multicore score is lower than single core. Tafak is that?
CAX11 (€3.29) performs on par with CPX21 (€7.05) when used as WireGuard client.
CPX11 (€3.85) gets 900 Mbps download and 1100 Mbps upload at best. It is possible that ARM hosts are not as crowded yet as AMD ones while I see 0% steal.
CAX11:
CPX21:
strange indeed. but still a beast.
Thermal throttling
Is thos a thing on a enterprise grade servers? Insane.
Yes, it was a case even with 5900X that BuyVM used, his solution was to disable turbo boost.
Now, 7950X has default PPT of 230W. Yes, default. Unless you will go watercooling there's no way to prevent throttling in 1U, possibly not even in 2U.
With 2x 100W CPUs you have 2x more surface area so its way easier to dissipate heat.
EPYCs are server grade, way bigger surface area and option to use two of them.
Ryzen's are hella fast, but also hella hot, they are meant for bigass coolers that just don't fit in most server chassis and if you go 4U it isjust not cost effective with other limitation in mind (like 128GB ram limit).
is a AMD Ryzen 9 7950X3D a enterprise grade server? i guess not.
That's CPU. You can put desktop CPU on a chassis with decent cooling. But yea, we talking hetzner here. Budget and efficiency.
By the way, integrated GPU brings any benefit to web hosting apps? I mean, nginx, apache, *sql ?
Integrated GPU helps for transcoding videos and some machine learning stuff.
Zero improvement in things you mentioned.
Hi,
Thanks all for your opinions and advice. I think I will buy a Ryzen 7700 or a 9050X. 7950x3D is out / no go.
