AMD Launches High-Frequency EPYC 7371 Processor
by Anton Shilov on November 13, 2018 10:12 AM EST
AMD has announced its new high-frequency EPYC 7371 processor designed for applications that benefit from high clocks. The CPU has 16 cores and is aimed at tasks like electronic design automation, high-frequency trading, and other. The EPYC 7371 can work in dual-socket configuration, thus offering up to 32 cores and 64 threads per box.
The AMD EPYC 7371 processor features 16 cores with SMT (spread across four eight-core Zen dies), 64 MB of L3 cache, an eight-channel DDR4 memory subsystem, and 128 PCIe lanes. The CPU features a 3.1 GHz default frequency, yet can run all cores at 3.6 GHz, or just eight cores at 3.8 GHz.
Being aimed at workloads that need a high single-thread performance, the EPYC 7371 takes advantage of its massive L3 cache along with its rather high frequencies. Meanwhile, its ability to work in dual-socket configuration is a major advantage that the EPYC 7371 has over other high-clock CPUs because the processor still enables 32 physical cores and 64 threads per system.

What is particularly noteworthy about the EPYC 7371 processor is that it is not officially listed over at AMD’s website. Perhaps, this part was initially offered to select customers only as an “off-roadmap” SKU, but demand from HPC vendors and traders encouraged AMD to expand availability of the chip to a broader range of its customers.
AMD plans to start selling its EPYC 7371 chip in Q1 2019, so before its next-generation EPYC ‘Rome’ chips will become available. The manufacturer did not touch upon pricing of its chip as it will naturally depend on volumes and other factors.

Here was one EPYC 7571 too.That one might also be a high clock part if the same rule applies

Great stuff. These are the SKUs AMD needs to supplant Xeon Ws in single socket workstations. Now for Dell or Lenovo to actually sell a workstation with such a chip.MrSpadge - Tuesday, November 13, 2018 - link
That's something I've always found missing since Threadripper, since this Epyc has the full memory bandwidth. Would be even better if it has up to 250 W TDP and was based on Zen+, mainly due to the more flexible boost. But given that Rome is appearing on the horizon it's understandable AMD is not validating the 12 nm chips for servers.CallumS - Tuesday, November 13, 2018 - link
This is great news and is something that I've been hoping that we'd see from AMD for a while now - a high frequency and relatively high core count EPYC SKU to provide solid single threaded performance for inventory/financial/ERP software usage and a better performance per core ratio for usage where software is licensed per CPU core/thread. I'm really looking forward to seeing this reviewed and available.diehardmacfan - Tuesday, November 13, 2018 - link
In an environment where licensing cores is the most expensive part of the datacenter, this was MUCH needed and now AMD is a viable alternative to Intel.drajitshnew - Wednesday, November 14, 2018 - link
The AMD EPYC 7371 processor features 16 cores with SMT (spread across four eight-core Zen dies==== 4x8 = 32. The processor is only 16 core. Likely an epyc version of 1950/2950lightningz71 - Wednesday, November 14, 2018 - link
No, its a true epyc processor. There are, indeed, 4 die with 8 cores each physically present in each of them. However, only 4 of those cores (likely 2 per CCX) are enabled per die, resulting in a 16 core processor with 8 channels of DRAM. Only enabling 4 cores per die gives a lot more power and thermal budget per core, per die, enabling the sustained frequency numbers listed.Forexmown - Monday, March 9, 2020 - link
