Epyc 7h12, new cpu that increases the frequencies of the epyc 7742

AMD wants to get the most out of its second-generation Rome EPYC processors, and to that end they have announced a new EPYC 7H12 chip with clocks higher than the 64-core EPYC 7742.

EPYC 7H12 increases the base frequency of the EPYC 7742 by 350 MHz

AMD has officially announced the EPYC 7H12, a 64-core processor that offers users a 350 MHz increase in base clock speed compared to AMD's existing EPYC 7742 and 280W TDP.

With this new processor, AMD is targeting the high-performance computing market, while offering the memory bandwidth and PCIe connectivity that EPYC is famous for. When you look at the performance of the raw LINPACK, the AMD EPYC 7H12 offers a performance increase of around 11% compared to the EPYC 7742 thanks to this increase in frequencies. Not bad for what a server CPU overclock is effectively.

CPU	Cores / Threads	Base (GHz)	Boost (GHz)	L3 Cache	TDP	Price (USD)
EPYC 7H12	64/128	2.60	3.30	256 MB	280 W	???
EPYC 7742	64/128	2.25	3.40	256 MB	225 W	$ 6950
EPYC 7702	64/128	2.00	3.35	256 MB	200 W	$ 6450
EPYC 7642	48/96	2.30	3.20	256 MB	225 W	$ 4775
EPYC 7552	48/96	2.20	3.30	192 MB	200 W	$ 4025

The AMD EPYC 7H12 is designed specifically for HPC customers, and the chip's TDP requirements demand a slightly better cooling solution than the average EPYC chip. This will in many cases mean the use of liquid cooling, which will be worth it for customers who demand the highest possible performance.

Strangely, AMD's new EPYC chip ships with somewhat slower 'boost' clock speeds compared to the EPYC 7742. Although this is a small disadvantage, the important thing is that 7H12 increases the base frequencies, so it seems to compensate for the drop in the 'boost' frequencies in daily use. We will keep you informed.
