AMD Rome Second Generation EPYC Review: 2x 64-core Benchmarked
by Johan De Gelas on August 7, 2019 7:00 PM ESTMurphy's Law
Anything That Can Go Wrong, Will Go Wrong
For those of you that may not know, I am an Academic Director of MCT at Howest University here in Belgium. I perform research in our labs here on big data analytics, virtualization, cloud computing, and server technology in general. We do all the testing here in the lab, and I also do launch article testing for AnandTech.
Undoubtedly, like most academic institutions, we have a summer vacation, where our labs are locked and we are told to get some sunlight. AMD's Rome launch has happened just as our lab closing started, and so I had the Rome server delivered to my home lab instead. The only issue was that our corresponding Intel server was still in the academic lab. Normally this isn't really a problem - even when the lab is open, I issue testing through remote access and process the data that way, in order to reboot the system and run tests and so forth. If a hardware change is needed, I need to be physically there, but usually this isn't a problem.
However, as Murphy's Law would have it, during testing for this review, our Domain Controller also crashed while our labs were closed. We could not reach our older servers any more. This has limited us somewhat in our testing - while I can test this Rome system during normal hours at the home lab (can't really run it overnight, it is a server and therefore loud), I couldn't issue any benchmarks to our Naples / Cascade Lake systems in the lab.
As a result, our only option was to limit ourselves to the benchmarks already done on the EPYC 7601, Skylake, and Cascade Lake machines. Rest assured that we will be back with our usual Big Data/AI and other real world tests once we can get our complete testing infrastructure up and running.
Benchmark Configuration and Methodology
All of our testing was conducted on Ubuntu Server 18.04 LTS, except for the EPYC 7742 server, which was running Ubuntu 19.04. The reason was simple: we were told that 19.04 had validated support for Rome, and with two weeks of testing time, we wanted to complete what was possible. Support (including X2APIC/IOMMU patches to utilize 256 threads) for Rome is available with Linux Kernel 4.19 and later.
You will notice that the DRAM capacity varies among our server configurations. This is of course a result of the fact that Xeons have access to six memory channels while EPYC CPUs have eight channels. As far as we know, all of our tests fit in 128 GB, so DRAM capacity should not have much influence on performance.
AMD Daytona - Dual EPYC 7742
AMD sent us the "Daytona XT" server, a reference platform build by ODM Quanta (D52BQ-2U).
CPU | AMD EPYC 7742 (2.25 GHz, 64c, 256 MB L3, 225W) |
RAM | 512 GB (16x32 GB) Micron DDR4-3200 |
Internal Disks | SAMSUNG MZ7LM240 (bootdisk) Micron 9300 3.84 TB (data) |
Motherboard | Daytona reference board: S5BQ |
PSU | PWS-1200 |
Although the 225W TDP CPUs needs extra heatspipes and heatsinks, there are still running on air cooling...
AMD EPYC 7601 – (2U Chassis)
CPU | Two EPYC 7601 (2.2 GHz, 32c, 8x8MB L3, 180W) |
RAM | 512 GB (16x32 GB) Samsung DDR4-2666 @2400 |
Internal Disks | SAMSUNG MZ7LM240 (bootdisk) Intel SSD3710 800 GB (data) |
Motherboard | AMD Speedway |
PSU | 1100W PSU (80+ Platinum) |
Intel's Xeon "Purley" Server – S2P2SY3Q (2U Chassis)
CPU | Two Intel Xeon Platinum 8280 (2.7 GHz, 28c, 38.5MB L3, 205W) Two Intel Xeon Platinum 8176 (2.1 GHz, 28c, 38.5MB L3, 165W) |
RAM | 384 GB (12x32 GB) Hynix DDR4-2666 |
Internal Disks | SAMSUNG MZ7LM240 (bootdisk) Micron 9300 3.84 TB (data) |
Motherboard | Intel S2600WF (Wolf Pass baseboard) |
Chipset | Intel Wellsburg B0 |
PSU | 1100W PSU (80+ Platinum) |
We enabled hyper-threading and Intel virtualization acceleration.

It's been a pretty good investment for me, bought at 8$ two years ago, seems like I'll keep it for a while longer.CheapSushi - Wednesday, August 7, 2019 - link
It's glorious...one might say.... even EPYC.abufrejoval - Wednesday, August 7, 2019 - link
Hard to believe a 64 core CPU can be had for the price of a used middle class car or the price of four GTX 2080ti.Of course once you add 2TB of RAM and as many PCIe 4 SSDs as those lanes will feed, it no longer feels that affordable.
There is a lot of clouds still running ancient Sandy/Ivy Bridge and Haswell CPUs: I guess replacing those will eat quite a lot of chips.
And to think that it's the very same 8-core part that powers the engire range: That stroke of simplicity and genius took so many years of planning ahead and staying on track during times when AMD was really not doing well. Almost makes you believe that corporations owned by share holders can actually sometimes actually execute a strategy, without Facebook type voting rights.

Sandy Bridge maxed out at 8c/16t.Ivy Bridge maxed out at 15c/30t.
Haswell maxed out at 18c/36t.
That means that a single socket Epyc 64c/128t can give you more CPU cores than a quad socket Sandy Bridge (32c/64t) or Ivy Bridge (60c/120t) and only a few less cores that a quad socket Haswell (72c/144t).

This is what we've all been waiting for!Eris_Floralia - Wednesday, August 7, 2019 - link
Thank you for all the work!quorm - Wednesday, August 7, 2019 - link
Given the range of configurations and prices here, I don't see much room for threadripper. Maybe 16 - 32 cores with higher clock speeds? Really wondering what a new threadripper can bring to the table.willis936 - Wednesday, August 7, 2019 - link
A reduced feature set and lower prices, namely.quorm - Wednesday, August 7, 2019 - link
Reduced in what way, though? I'm assuming threadripper will be 4 chiplets, 64 pcie lanes, single socket only. All ryzen support ecc.So, what can it offer? At 32 cores, 8 channel memory becomes useful for a lot of workloads. Seems like a lot of professionals would just choose epyc this time. On the other end, I don't think any gamers need more than a 3900x/3950x. Is threadripper just going to be for bragging rights?
quorm - Wednesday, August 7, 2019 - link
Sorry, forgot to add, 3950x is $750, epyc 7302p is $825. Where is threadripper going to fit?
