"perform better" doesnt mean anything.
do your application require specific feature? do they benefit from scaling up or sideways (do your apps need clock speed?) Next, what are your IO needs? the Xeon part has 40 lanes of gen4 PCIe; the Epyc has 28 lanes of gen5. Next- power considerations- the Intel part is 95W, AMD is 65W (this will dictate how much power it will consume and how much heat it generates; more heat means potentially louder.)
If this is for homelab use, both are fine.

in that case, the only difference is in load calculation. Since Zen4 and Rocket Lake have similar IPC performance, its a simple matter of:
Relative Performance, Xeon E-2388G (3.2GHz base, 8 core)= 25.6
Relative Performance, AMD EPYC 4244P (3.8GHz base, 6 cores)=22.8
On paper, sure looks like the Xeon has more potential, right? well, not so fast. Turbo availability (which depends on cpu cooling infrastructure) will mess with those figures. it also depends on whether your total load is constant or bursty; INDIVIDUAL vms may perform better on the AMD nodes, but total package load may tilt toward the intel. Then there's the matter of RAM speed- the Epyc is a DDR5 part; the Intel DDR4. depending on what modules speed and count installed in the individidual servers the performance different can be substantial just on that account.
In the final analysis- if you dont know how much load you have, and what your bottlenecks are, you're shooting in the dark.
