@JayN, did you know that electricity is not free? Intel Xeon Platinum 8260Y vs AMD Epyc 7742: 14.

I want to run 4 MPI jobs on 2 x AMD EPYC 7742 processors in the most efficient way. The EPYC 7742 seems to be a force to be reckoned with when the battle takes place on even ground. EPYC 7742 is definitely peerless in 2-CPU servers (comparable to quad 8280 which cost $$$$$). While it is true that you cannot use the Intel Optane DCPMMs with AMD EPYC, you can use their standard NVMe form factor.

And since we would more likely than not be piecemeal replacing/adding additional servers in the future versus a forklift replacement, the pain involved from running VMware on split AMD/Intel isn’t work the headaches (no live vMotion.). 00 For example, the results of lscpu indicate that each node organizes the threads in two groups. Intel is getting some limited traction with the Xeon Platinum 9200 series at up to 56 cores, but that is not socketed meaning Intel supplies both chips and the motherboard. One can configure the cTDP up to 240W.

This tool uses JavaScript and much of it will not work correctly without it enabled. I did not see a 4x 16 core Intel Xeon topology map in our CMS, but here is a 4x 12 Intel Xeon Scalable topology map from our Supermicro SYS-2049U-TR4 Review: As you can see, there are more NUMA domains and PCIe devices sit on different sockets which can hammer inter-socket bandwidth over UPI. However long it takes AMD to move up from Rome’s AVX256 to AVX512 AMD still has its GPU accelerator products for massive DP FP workloads but is that AVX512 market large enough to go after at this point in time for AMD on CPUs. “The other thing is that the person who makes the purchasing decisions isn’t interested in even looking at AMD’s cost/performance. This is what we’ll be doing, for sure. We wanted to focus on the cache and NUMA advantages of these 64 core chips for a moment. If you want a socketed platform, you are limited to the Platinum 8200 series today. Next, let us look at our performance benchmarks before getting to market positioning and our final words. The Xeon Platinum 9200 series systems will not have features such as iDRAC and HPE iLO.

A single job runs about 4 times more efficiently than running 4 jobs simultaneously. Here is what the lscpu output looks like for an AMD EPYC 7742: Cores are easy to point to as being more. And with the only question remaining to be answered is concerning the Zen-3 CCD-DIE’s actual Fabric Topology and will that be a Ring BUS(CCD Die Only) with inter CCD-DIE Infinity Fabric On Package interfacing or some more complicated topology with lower latency as well. With architecture, performance, and security leadership, our approach to processor design accelerates the pace of innovation so that you can break through years of data center stagnation. There is 256MB of onboard L3 cache. According to this article, Cooper Lake has been sampling since May. Patrick is a consultant in the technology industry and has worked with numerous large hardware and storage vendors in the Silicon Valley.

Would AVX512 be nice to have? Each job uses 64 threads. Even the Platinum 9200 series enumerates each die in a CPU package separately more similar to how the AMD EPYC 7001 series did than the EPYC 7002 series. Glad to see Tyan on the bench. Also, the Platinum 9200 uses significantly more power making it a less eco-friendly solution for general-purpose workloads.

This is an exact parallel to how accelerators like the NVIDIA Tesla V100S, Intel’s next-gen Xe HPC GPU, Intel’s Nervana NNP-T, Intel’s new Agilex FPGAs, Xilinx Versal AI Core ACAP, Habana Labs Gaudi AI training accelerator, the Graphcore C2 IPU, and even the Cerebras Wafer Scale Engine AI chip are designed. Mouse clicks don't always register. AVX 512 is no necessity in todays workloads (except AI HPC and other niches of course) Then you’re left with bfloat16, which is probably not utilized by anyone exept the HPC and AI guys, and Intel is left with the position AMD had when they launched Bulldozer for Server – funny how things changed.

Also, am I the only one wondering why nobody says to these 99% intel discount arguments that giving discounted prices for high volume orders is not illegal for AMD either? Slow going. If you count the PCIe lanes and bandwidth in the platform, Tyan is offering more PCIe I/O than a dual-socket Xeon server in a single socket AMD EPYC 7002 server. The 28 core Intel Xeon Platinum 8280 has 66.5MB of L2 plus L3 cache. AMD's Rome platform solves the concerns that first gen Naples had, plus this CPU family is designed to do many things: a new CPU microarchitecture on … In order to minimize potential conflicts, would it be helpful to specify what threads are used by each job. You have entered an incorrect email address! Now having to re-run everything which means swapping processors. We were going to use a dual AMD EPYC 7002 series platform for this review, but the single AMD EPYC 7742 is closer to two Xeons and we have an acceptable, at best, quad Xeon 6200/ 8200 data set.

In their mind, Intel is king and AMD is nothing but compatibility trouble.”, Nobody ever got fired for buying Intel eh? By opting-in you agree to have us send you our newsletter.

My MSP seemed a little surprised I was asking about EPYC, too.

AMD Epyc 7742 vs Intel Core i9-10900X: 18. Please turn JavaScript back on and reload this page. https://www.oracle.com/corporate/pressrelease/oow19-oracle-intel-partner-optane-exadata-091619.html. sure, but for the few workloads that really benefit a couple of GPU’s can handle the bulk of the use cases better for less $$$. All this is achieved using a single AMD EPYC 7002 series CPU. Now we see one domain for 64 cores or two for 128 cores.

Intel Core i7-8700K vs AMD Epyc 7742: 19. That has an important impact on another area: NUMA domains. One cannot specify one server model and run from a single socket low-end SKU to a dual-socket high core count SKU.

AMD’s yearly Zen based CPU hardware/micro-architectural update cadence is now in full swing with no signs of any rough patches currently and TSMC’s 5nm apparently progressing faster than was expected. Epyc/Milan is sure to improve performance once that CCX Unit construct is supplanted by just the 8 core CCD-DIE that shares among its 8 CPU cores the CCD-DIE’s total allotment of L3. Thank you! You are going to see more about this platform, but this is a PCIe Gen4 single-socket platform from Tyan that has 16x front U.2 NVMe bays, 10x front SATA/ SAS bays, two rear 2.5″ SATA OS SSD bays, six expansion slots on risers and an OCP mezzanine slot. Absolutely needing AVX-512 or optane dimms is about the only reason. I want to run 4 MPI jobs on 2 x AMD EPYC 7742 processors in the most efficient way. Thanks for not getting bogged in the weeds.

AMD has other SKUs in its stack which may work better for organizations (e.g. Really, a 60-70% Intel discount isn’t a good enough reason to stay with them. Save my name, email, and website in this browser for the next time I comment. Quad Xeon servers currently have lower inter-socket bandwidth which adds to that stress. Big fast caches, close to the compute resources. For most of our charts (except the dual-socket virtualization testing) we are using the Tyan Transport SX TS65A-B8036. With that, the AMD EPYC 7742 has about 4.5MB of L2 + L3 cache per core. Not sure what the issue could be caused by so I'm trying to ask everywhere. We see them “promised” with the updated gromacs code for many reviews now, but nothing so far, or am I overlooking something? Most in the market will continue buying what they bought before. While on-prem hardware is no longer the flavour of the month where I am (and hasn’t been for some time) it’s still exciting for me to see how well AMD is doing. So basically the only reason you should even consider Intel is if they discount you 60% or you need AVX-512? 256MB of L3 cache is an enormous number in the current x86 ecosystem. Even if you get a 60-70% Intel discount you’re still getting it basically at what AMD charges, but you’re not getting the lower NUMA node count, lower TDP (hence lower electric/cooling costs), rack space savings, PCI gen4, etc, etc.

If you want a general-purpose x86 server today that can offer huge consolidation ratios over Intel Xeon E5 V1-V4 and even Xeon Scalable servers, the AMD EPYC 7742 is simply the way to go.
