Amd epyc 'rome' 64-core has frequencies of 1.4 and 2.2 ghz

AMD's new 64-core, 128-wire EPYC 'Rome' processor has appeared in an online database, indicating that the first chips run on a 1.4 GHz base clock and can reach 2.2 GHz..

AMD EPYC 'Rome' will be released in the middle of this year and will offer 64 cores and 128 threads

AMD announced earlier this year that 64-core, 128-wire EPYC 'Rome' processors would hit the market in mid-2019, perhaps paving the way for a major victory against Intel as AMD moves toward a manufacturing process for 7nm, when its direct competitor remains at 14nm in the server segment.

Several submissions to the SiSoft Sandra database regarding the EPYC processor have come to light in recent months, most of which carry the descriptor "Z" at the beginning of the product identifier ZS1406E2VJUG5_22 / 14_N. This means that they are qualification samples, which means that the chip is very close to its final design.

Comparison chart

	Cores / Threads	Clock Base	Clock Turbo	L3 cache	TDP
AMD ZS1406E2VJUG5_22 / 14_N (early silicon)	64/128	1.4 GHz	2.2 GHz	256MB	?
AMD EPYC 7601	32/64	2.2 GHz	3.2 GHz	64MB	180W
Intel Xeon Platinum 8180	28/56	2.8 GHz	3.8 GHz	38.5MB	205W

The test system is listed on a dual-socket Dell PowerEdge R7515 server. By gutting the name of the product, the clock speeds, the number of cores, the threads and which has 64x512KB of L2 cache and 256MB of L3 cache are revealed .

Frequencies may seem somewhat low, but keep in mind that the chip has no less than 64 cores. By increasing the frequencies too much in such a large number of cores, the consumption and generation of heat would be excessive.

For example, AMD's 32-core, 64-wire 64-core EPYC 7601 has a base frequency of 2.2 GHz and a Turbo frequency of 3.2 GHz, which might suggest that duplicating Rome's cores required even more tweaking to Reduce heat, even with a smaller and more efficient 7nm process. AMD has not disclosed the TDP ranges for its EPYC Rome processors, but previous models range from 120W to 180W.
