AMD released 7nm “Rome” series of Epyc server CPUs, with up to 64 cores, 128 threads, 225W TDPs, and a maximum clock speed of up to 3.4GHz. While third-generation Ryzen is aimed at enthusiasts the server market is where AMD truly wants to play. AMD claims that Epyc sets no fewer than 80 new world records for CPU performance as measured in a wide range of industry-standard benchmarks.

Essentially AMD now offers far better price performance compared to Intel:
Dual CPU HPE DL385 Gen10 with AMD CPUs has SPECrate2017_int_base of 620:
Dual CPU HPE DL380 Gen10 with Intel Xeon CPUs has has SPECrate2017_int_base of 338:
Amazing that a 2 RU server has 128 CPU cores!!!:
*Note: Server has 32 DDR4 DIMM slots.
With commodity two CPU server in 2RU we have 128 CPU cores. With virtualisation assuming a 4:1 vCPU:pCPU ratio can have 512 vCPUs on such a server...assuming average VM is 2 CPUs then 256 VMs in small 2RU server.
Much more expensive IBM server with double the number of CPUs - Quad CPU IBM Power E950 with IBM Power9 CPUs has has SPECrate2017_int_base of 392:
HPE published record benchmarks using the new AMD EPYC Rome CPUs:
With commodity two CPU server in 2RU we have 128 CPU cores. With virtualisation assuming a 4:1 vCPU:pCPU ratio can have 512 vCPUs on such a server...assuming average VM is 2 CPUs then 256 VMs in small 2RU server.
When VMware and other software licencing is considered AMD AMD Epyc offers far better price performance than Intel Xeon for virtualisation.
