As you all know, ZEN3-based Ryzen processors should arrive later this year, according to a new leak, AMD is already testing at least three models, from which specifications now have surfaced.

A table of OPN info has leaked though Germany based Igors lab, these are interesting as with OPNs information such frequencies and core counts are listed. The slower model with 8 cores and 16 threads will have a base frequency of 3800MHz and boost at 4400MHz, while the faster 8-core model will have a base frequency of 4000MHz and boost at 4600MHz. Regarding the 16-core and 32-threads model, it will have a base frequency of 3700MHz and boost to 4600MHz.

AMD is testing the following engineering samples codenamed "Vermeer":

Name: Vermeer (VMR)
Family: 19h
Models: 20h-2Fh
CPUID: 0xa20f00

OPN 1: 100-000000063-07_46 / 40_N
OPN 2: 100-000000063-08_46 / 40_Y
OPN 3: 100-000000063-23_44 / 38_N
Revision: A0
Cores: 8
Threads: 16

OPN 1: 100-000000059-14_46 / 37_Y
OPN 2: 100-000000059-15_46 / 37_N
Revision: A0
Cores: 16
Threads: 32

One should realize that these likely are engineering samples, and with anything tagged ES, nothing is final. It will be interesting to see. Chatter on the web indicated an IPC increase as well, to 20%. Ryzen 4000 is expected to make a debut in September.
