After all, such a link is still likely to limit the peak memory speed, and DDR5 is already expected to scale past 7000 MT/s. Of course, AMD's aforementioned emphasis on Zen 4's ability to hot-clock DDR5 could just as easily be an indication that the Infinity Fabric clock on Ryzen 7000 processors ISN'T linked to memory speed anymore. Still, it's likely that Apacer was given these numbers by AMD, so we're ready to take them at face value. The slide is buried in an obscure page that outlines the benefits of DDR5 memory over DDR4, like higher transfer rates, higher density, and on-module power management, and it certainly isn't official AMD material, which means it's possible that AMD's Ryzen 7000 chips could be spec'd for lower or even higher DDR5 speeds. That's a fair whack faster than the DDR5-4800 officially supported by Intel's latest chips, although Intel's processors certainly aren't limited to just that. If you are jumping on the AMD Zen 4 bandwagon, the Ryzen 9 7900X processor blends the needs of both enthusiast and gamers into one fantastic CPU LGA Socket AM5.

EPYC Genoa can handle down to one memmory channel configurations while for this testing the focus was on 6 memory channels and above - simply for not being too memory constrained, reducing the testing burden with having a lot of different tests being limited by this lone EPYC Genoa server at the moment, and the low likelihood of users procuring a higher-tier EPYC 9004 series processor and running in such a RAM limited scenario.Image: Apacer Industrial, via point in the favor of that argument is the slide above from Apacer Industrial, discovered by Twitter leaker which clearly marks down Zen 4-based Ryzen and EPYC processors for DDR5 memory running at up to 5200 MT/s. All of the memory was 64 GB DDR5-4800MT/s Samsung M321R8GA0BB0-CQKEG memory modules, kindly supplied by AMD as part of the EPYC Genoa review kit. With the AMD Titanite reference server and dual EPYC 9654 64-core processors, I completed various (mostly real-world focused) benchmarks at 6, 8, 10, and 12 memory channels. So going for 12 DIMMs or even 24 DIMMs for a two socket AMD 4th Gen EPYC server can quickly add up. AMD has confirmed that it will be hosting the unveiling of its Ryzen 7000 'Zen 4' CPUs, AM5 platform & DDR5 EXPO memory on the 29th of August. The 64GB DDR5-4800 server memory modules are retailing for around $350. The transition to the LGA1718 Socket AM5 allows AMD to use next-generation I/O, including DDR5 memory, and PCI-Express Gen 5, both for the graphics card, and the M.2 NVMe slot attached to the CPU socket. Obviously though not all workloads are very memory intensive, so these benchmarks are intended both as a mix of benchmarks showing how the EPYC 9654 2P performance responded under a mix of workloads whether you are trying to gauge if it's worthwhile initially going for 12 (or 24) DIMMs or simply need some independent numbers to help justify the expenditure to your boss/management.įor those that haven't looked at DDR5 server memory pricing, as of writing the cheapest DIMMs I have seen are the Samsung DDR5-4800 16GB memory modules at around $100 USD or $183 USD for the 32GB version. With Zen 4, AMD is introducing a new instruction set for AI compute acceleration. Thus I set out to run some benchmarks over the holidays looking at the EPYC Genoa performance from 6 up through 12 memory channels with these Zen 4 server processors.įor memory intensive workloads the scaling up through 12 channels was there and the EPYC 9654 processors proved they could effectively make use of all twelve memory channels per socket. But the cost of populating all 12 memory channels - especially with initial DDR5 server memory pricing - may be too much to handle at once for some deployments and tougher to justify within organizations during these turbulent economic times.

This is a big upgrade over prior generations of EPYC processors with eight channels of DDR4-3200 memory and what is found with current Xeon Scalable 'Ice Lake' processors.

Zen 4 only makes sense for users looking to buy or build a new PC from scratch, but.

In this article is a wide assortment of benchmarks looking at the AMD EPYC 9654 performance across varying numbers of populated DDR5 memory channels.ĪMD 4th Gen EPYC processors support twelve DDR5 memory channels at DDR5-4800 speeds and can handle up to 6TB of addressable memory per socket. The companys 13th-generation processors support DDR4 RAM but let users upgrade to DDR5 whenever theyre ready. In addition to the big performance uplift from AVX-512, up to 96 cores per socket, and other Zen 4 architectural improvements, also empowering the EPYC 9004 'Genoa' processors is the support for up to 12 channels of DDR5-4800 memory.
