AMD 4564P

The EPYC 4564P delivers a 64,443 PassMark multi-thread score, putting it in the 96th percentile. That's top-tier performance for a chip that fits in a consumer AM5 socket. The catch is a 200W TDP and an efficiency score of just 42.8/100. If you need 16 cores, 32 threads, and up to 2TB of ECC DDR5, this is a beast. Just be ready for the heat.

The 4564P is a monster when it comes to multi-threaded work. That 64,443 PassMark score is one of the best we've seen, and it translates to real-world speed in rendering, code compilation, and data crunching. The 16 Zen 4 cores and 32 threads at a 5.7GHz boost clock are the engine here. The 64MB of L3 cache helps keep those cores fed, and the single-thread score of 4,292 means even lightly threaded apps feel fast. This is a chip that doesn't really have a weak spot in raw compute.

Memory support is another highlight. You can stuff up to 2048GB of DDR5 ECC RAM in here. That's 2TB. For a consumer socket, that's absurd. The platform score of 88th percentile reflects that flexibility. PCIe 5.0 support is there too, so you can pair this with fast storage and GPUs without bottlenecking. The integrated Radeon Graphics is basic, but it's handy for troubleshooting or a headless server setup. Just don't expect to game on it.

The EPYC 4564P sits in a strange spot. The Intel Core Ultra 9 285K is a natural competitor, and it's a more balanced consumer chip with better efficiency. But the 4564P crushes it in multi-threaded throughput. The 96th percentile multi-thread score is the story here. The other listed competitors, like the CG CHIPS GATE EPYC and the Core i9 X-series parts, are either older server silicon or niche listings. The 4564P's single-thread performance of 4,292 is actually better than most of those older chips, which is rare for a server part. If you need ECC memory support and massive RAM capacity, the 4564P is the clear choice. If you want a quieter, cooler system for mixed use, the Core Ultra 9 285K might be a better fit.

Pricing is all over the place. In the US, you'll see listings from $768 to $935. That's a $167 spread for the exact same chip. Best Buy has it listed, and they offer a price match guarantee, so do your homework before you buy. In Europe, the range is €640 to €792 across four listings. The best deal we see is at the low end of those ranges, so shop around. For a 16-core server chip with this level of performance, even the high end isn't unreasonable. But there's no reason to pay $935 when $768 is available. The value proposition is strong if you need the cores and memory bandwidth, but the power draw means you'll pay more in electricity over time.

The AMD EPYC 4564P is a weird and wonderful chip. It's a server processor that slots into a consumer AM5 motherboard, and it brings some serious firepower. We're talking a PassMark multi-thread score of 64,443, which puts it in the 96th percentile of everything we've tested. That's not just good, it's top of the charts for raw CPU grunt. The single-core score of 4,292 is equally impressive, landing in the 95th percentile. So you get a chip that can chew through massive parallel workloads and still feel snappy in everyday tasks.

But here's the catch. This is a 200W TDP part with a 230W turbo. That's a lot of heat to manage on a consumer socket. And while the efficiency score of 42.8/100 isn't a disaster, it's the weakest area by a wide margin. You're buying raw performance, not power sipping. If you need a workstation that can handle heavy rendering, virtualization, or AI inference without jumping to a full server platform, this chip is a compelling option. Just make sure your cooling and power supply are up to the task.

Skip this chip if you care about efficiency or quiet operation. The 42.8/100 efficiency score is the weakest area, and a 200W TDP means your system will run hot and loud under load. If you're building a general-purpose PC for gaming, browsing, and light productivity, this is overkill. You'll pay more for power and cooling than you'll ever get back in performance. Also skip it if you need proven reliability in a production server. With zero customer reviews and a 2nd percentile social proof score, there's no track record to lean on. This is a chip for enthusiasts and tinkerers who know exactly what they're getting into.

The AMD EPYC 4564P is a niche product that nails its niche. If you need server-class multi-threading, ECC memory, and up to 2TB of RAM on a consumer platform, this is the chip to beat. The 64,443 multi-thread score and 4,292 single-thread score are both elite. The trade-off is power draw and heat. A 200W TDP on AM5 means you need a beefy cooler and a quality motherboard. The efficiency score of 42.8/100 is the one real blemish. But for a workstation or home server that's going to be under load constantly, the raw performance justifies the power bill. Just buy from the vendor with the lowest price.
