AMD’s 64-Core, 128-Thread EPYC Rome to Impact Intel’s Server Dominance

Earlier this year, AMD’s 64-Core, 128-Thread EPYC Rome Server chips were announced with an expected release later this year. Most manufacturers receive an early sample for testing and apparently, several benchmarks of the upcoming EPYC Rome chips have leaked on public databases.

Over the past few months, there have been several submissions to SiSoftware Official Live Ranker with the ZS1406E2VJUG5_22/14_N product code. From the Result ID of the processors, we can infer that it has 64x512KB of L2 and 16x16MB of L3 cache memory. The processors seem to have a base frequency of 1.4 GHz with 2.2 GHz boost with all 3 of them having 128 threads.

The current generation EPYC 7000 series with 32-Cores and 64-Threads have 2.2 GHz base and 3.2 GHz boost frequency. This would mean that leaked benchmarks probably do not represent the flagship model and are probably an updated version of the EPYC 7251 or the 7281 chips which have a TDP of 120-155/170 W.

The new processors use AMD’s Zen2 architecture based on the 7nm process. This results in less than 1/2 the energy being consumed for any process over the current chips based on the Zen+ architecture.

Intel’s Xeon Platinum 8180 boasts 28-Cores (56T) with a 2.8 GHz base and a 3.8 GHz boost clock. Compared to AMD Rome, Intel’s Xeon 8180 loses by 19% in the scientific NAMD workload.


Moreover, there have been rumors about Google employing the Rome processors for their upcoming streaming platform, Stadia. Recently, AMD released a 2-page long white paper demonstrating the “Intel Tax” as extra for much-needed features and performance.

With the Ryzen 3000 processors coming in Q2 2019 and the 64-Core Epyc chips expected to follow shortly afterwards, AMD is set to leave a mark on both the domestic as well as the enterprise market.

According to DigiTimes, AMD EPYC will manage to squeeze Intel below the 90% server processor market share point by the end of 2020. This further paves the way for AMD’s rise in the server market and Intel will need to come up with products based on the 10nm process sooner than 2020.

I've damaged way too many processors than I'd like to admit. Music and Sim Racing keep me sane; that is until I get a strange itch to tinker with stuff again.
