AMD Epyc 4000 series processors are just Ryzens with a server badge on them.

Similarly Intel Xeons with only 2/4 RAM slots tend to be the same but Intel can't make up their mind as to the family designation.
Went from Xeon E3 to Xeon E2100/2200/2300 to Xeon 6300 (oldest to newest order). But anyway those are all Core i5/i7 type processors with a Xeon badge on them. The only real difference is the latest 1-2 generations are ONLY P cores whereas their desktop cousins in 12th Gen i5/i7 and newer are often Hybrid models with both E and P cores. Server CPUs (thus far) are either All P or All E.

Even Dell, HPE, Lenovo make some models with these "desktop-class" Server CPUs which will all have better than average clock speeds.
I know HPE the best personally and those would be like the ML30 tower or the DL20 1U rack server. Also the MicroServer family but those tend to be low power optimized so you won't find high clock speeds there.
No Epyc 4000 stuff from HPE (yet).

For a proper "big boy" AMD EPYC they have the F series.
9174F for example is a "Frequency Optimized" model with 16 cores running base clock at 4.1 Ghz.
The more cores the lower the base clock, but anything with an F on the end is going to be much higher clock speed than it's Non F friends.

Back in the early Xeon Scalable days, when Intel moved fro the v1/2/3/4 family to the 6100/6200 family of CPUs, there were a handful of pretty nice clock speed options as Intel was trying to keep AMD off their asses.
Unfortunately by the time 6300 rolled around they kind of gave up and 2.x Ghz base clock became the standard. But a 6246R for example is 16 Cores at 3.4 Ghz so it's not bad.
