AMD 4564P

The EPYC 4564P posts a PassMark multi-thread score of 64,357, good for the 96th percentile, and a 4,292 single-thread score in the 94th percentile. It's a 16-core, 32-thread server chip on a desktop AM5 socket with ECC DDR5 support up to 2,048GB. Efficiency is the weak spot at 45.3/100, and affordability is even worse at the 10th percentile, so bring a big cooler and a bigger budget.

Let's talk numbers, because this chip has plenty. The PassMark multi-thread score of 64,357 is the headline act. That's 96th percentile territory, meaning it outmuscles nearly everything else in our database for parallel workloads. Video encoding, 3D rendering, compiling large codebases, running multiple VMs, this thing chews through them. The 16 cores and 32 threads are backed by 64MB of L3 cache and 16MB of L2, so data-hungry tasks don't stall out waiting for memory. And with DDR5 support up to a frankly absurd 2,048GB, you can build a memory monster if your wallet allows.

Single-thread performance is equally impressive. The 4,292 PassMark single-thread score puts it in the 94th percentile, which means everyday responsiveness and lightly-threaded apps feel snappy. The 5.7GHz boost clock is doing real work here. The integrated Radeon Graphics are a nice bonus for a server chip, giving you display output without a discrete GPU. PCIe 5.0 support rounds out the platform. The one caveat: all that performance comes with a 200W TDP and 230W turbo draw. You'll want a beefy cooler and a board with solid VRMs. This is not a chip you drop into a cheap B650 board and forget about.

The EPYC 4564P sits in an odd competitive space. Against the Intel Core Ultra 9 285K, you're looking at a different philosophy: Intel's chip is a consumer flagship with strong single-thread and efficiency, while the EPYC is a server part crammed into a desktop socket. The EPYC's 64,357 multi-thread score and 96th percentile ranking give it a clear edge for heavily parallel server and workstation tasks, but the Intel chip will likely sip power by comparison. The MICRO CENTER 9950X3DMAGX870ETMKWF bundle is another interesting alternative, pairing a high-end Ryzen with a motherboard for a potentially better overall platform value, though the EPYC's ECC memory support and 2,048GB ceiling are things that bundle can't match. The G.Skill Trident Z Neo is memory, not a CPU, so that's not a direct comparison, but it's a reminder that this chip needs fast DDR5 to shine. If you need ECC memory and server-grade reliability, the EPYC is the pick. If you want efficiency and a more balanced desktop experience, the Core Ultra 9 285K is worth a hard look.

Value is where the EPYC 4564P gets complicated. The affordability ranking sits in the 10th percentile, which is about as bad as it gets in our database. US prices range from USD 768 to USD 935 across two listings, a spread of USD 167. That's a meaningful chunk of change for the same silicon. If you're in the US, the lower end of that range is the obvious move, but you'll need to hunt for it. European buyers see a similar story, with EUR prices spanning EUR 640 to EUR 812 across four listings in Germany, Spain, France, and Italy. That's a EUR 172 gap. The cheapest EUR listing is the one to chase if you're on that side of the Atlantic. For what you get, 16 cores of EPYC-class performance in a desktop socket, the price isn't unreasonable. But it's not a bargain, and the efficiency hit means you'll pay more over time in electricity and cooling. If you're building a 24/7 server, factor that into the total cost.

The AMD EPYC 4564P is a weird and wonderful chip. It's a server processor that slots into a standard AM5 desktop socket, and it brings serious firepower: 16 cores, 32 threads, a 5.7GHz boost clock, and a PassMark multi-thread score of 64,357. That puts it in the 96th percentile for multi-threaded work in our database, which is basically top of the charts for anything you can drop into a consumer board. Single-thread performance is no slouch either, with a 4,292 score landing it in the 94th percentile. If you need a workstation that can also moonlight as a server, this thing is a statement piece.

But it's not all sunshine. The efficiency score sits at 45.3 out of 100, which is the weakest area by a wide margin. A 200W TDP and 230W turbo draw mean you'll need real cooling and a power supply that isn't messing around. And the affordability ranking is brutal: 10th percentile. This is not a budget chip, and the price spread across vendors proves it. Still, for raw productivity, it scores a perfect 100/100 in our testing, with server workloads at 95.4 and AI/LLM tasks at 88.1. It's a niche monster, but within that niche, it's hard to beat.

Skip the EPYC 4564P if efficiency matters to you. The 45.3/100 efficiency score is the chip's biggest weakness, and a 200W TDP with 230W turbo draw means higher electricity bills and more heat to manage. If you're building a quiet home server or a small form factor workstation, this is the wrong tool. Gamers should also look elsewhere: the single-thread score of 4,292 is strong, but you're paying a premium for ECC support, a 2,048GB memory ceiling, and server validation that games simply don't use. And if you're on a tight budget, the 10th percentile affordability ranking should be a dealbreaker. There are cheaper ways to get 16 cores of desktop performance without the server tax.

The AMD EPYC 4564P is a specialized tool, and it's unapologetic about it. With a 100/100 productivity score, a 95.4 server score, and multi-thread performance in the 96th percentile, it's one of the best options we've seen for anyone who needs serious parallel compute in a desktop form factor. The 5.7GHz boost and 4,292 single-thread score mean it's no slouch for everyday tasks either. But the efficiency score of 45.3 and the 10th percentile affordability ranking are real trade-offs. You're paying a premium for server DNA, and you'll pay again on your power bill. If your workload justifies it, rendering, compiling, virtualization, AI tinkering, this chip delivers. If you're just gaming or browsing, you're buying a race car to drive to the grocery store.
