AMD EPYC 9754 128-core SP5

128 cores of Zen 4c fury with a PassMark score that makes other server chips look sleepy. Just make sure your power bill and cooling setup are ready for the 360W heat.

The multi-threaded numbers are absurd. 115,016 in PassMark puts this in the 99th percentile for multi-thread, and our AI and platform scores land at the very top of the charts. The 256MB of L3 cache and 12-channel DDR5 memory give it serious bandwidth for virtualization and dense container workloads. Single-thread is a different story. 2,403 puts it at the 67th percentile, which is fine but not exciting. The 3.1GHz boost clock is modest, and that's the trade-off for 128 cores on a 5nm process. Efficiency is the real weak spot at 39.7 out of 100. At 360W TDP and 400W turbo, this thing drinks power like it's going out of style.

The EPYC 9754 goes head to head with the SMC EPYC 9555P and HP Xeon P67080-B21 in the server space. The 9555P is a solid alternative if you want similar core counts with different power characteristics, but the 9754's 256MB of L3 cache gives it an edge in cache-sensitive workloads. Against the Xeon, the AMD chip generally wins on raw core count and memory bandwidth, though Intel's ecosystem support can be a factor in enterprise deployments. The Intel Core Ultra 9 285K and D&H Core i9 are desktop chips and honestly not in the same league for server tasks, so if you're cross-shopping those, you're looking at the wrong category.

At $5,499 USD, this is a lot of money for a CPU. But if you're running a virtualization host or AI inference farm where core count is king, the price per core is actually reasonable. You're getting 128 cores for under $43 per core, which is hard to beat in the server space. Just don't buy this for a workstation unless you have a very specific reason.

The AMD EPYC 9754 is a 128-core monster built for one thing: crushing heavily threaded server workloads. With 256 threads and a PassMark multi-core score of 115,016, this chip sits at the absolute top of our database for platform and AI performance. It's not a desktop toy, it's a data center workhorse that happens to be available in a tray pack if you know where to look.

If you're building a gaming rig or a general-purpose workstation, this isn't it. Go get a Ryzen 9 or Core i9 instead. This chip is for people running dense virtualization, AI inference, or other heavily threaded server workloads where 256 threads actually matter.

The EPYC 9754 is the right choice if you need maximum thread density and don't care about power draw. It's a specialized tool for specialized workloads, and in that role it's exceptional. For general-purpose servers or anything single-thread dependent, you're better off with a higher-clocked chip with fewer cores.
