AMD EPYC 9355P 32-core SP5

The EPYC 9355P is a 32-core server beast with a 99th percentile multi-thread score and 256MB of L3 cache. It's built for heavy parallel workloads, not gaming or casual use. Efficiency is the weak spot, but if you need this many cores, it's a strong pick.

The 9355P posts a PassMark multi-thread score of 96,603, which puts it in the 99th percentile for multi-threaded performance. That's top of the charts, best-in-class territory. Single-thread comes in at 3,747, which is solid but not earth-shattering, landing around the 89th percentile. The 256MB of L3 cache is a huge deal for database work, virtualization, and AI inference. The 280W TDP is no joke though, and efficiency takes a hit as a result. You'll need serious cooling and a board with an SP5 socket.

Against the Intel Core Ultra 9 285K, the 9355P wins on raw core count and multi-threaded throughput, but the Intel chip is a consumer desktop part with much better single-thread performance and lower power draw. The HPE Xeon P67080-B21 is a closer competitor in the server space, but the EPYC's 256MB of L3 cache gives it an edge for memory-hungry workloads. The other 'competitors' in our list, like the MSI motherboard and Thermal Grizzly paste, aren't really direct rivals, they're just adjacent products. The EPYC 9355P sits in a weird spot: overkill for most desktops, but a strong value for a single-socket server.

Value is tricky here because we don't have a confirmed price in our database. Listings show around $5,004 USD, 6,922 CAD, 4,178 EUR, and 3,901 GBP depending on region. For a 32-core EPYC with this level of multi-threaded performance, that's actually reasonable compared to older EPYC or Xeon parts. But if you don't need 32 cores, you're paying for silicon you'll never use. The efficiency score of 41.6 out of 100 is the weakest area, so factor in higher power bills and cooling costs.

The AMD EPYC 9355P is a 32-core, 64-thread monster built on AMD's 4nm Turin architecture. It's aimed squarely at servers and heavy productivity rigs, not your average gaming PC. With a 4.4GHz boost clock and 256MB of L3 cache, this thing is built to chew through parallel workloads without breaking a sweat.

We don't have a price in our database for this exact listing, but it's a server chip, so expect to pay server money. The specs are serious, and the benchmark numbers back that up. This is a workstation or data center part, not something you toss into a home build for fun.

Skip this if you're building a gaming PC or a general home office machine. The single-thread performance is fine but not worth the cost and power draw. If you need strong single-core speed and lower power consumption, look at consumer chips like the Ryzen 7 or Core Ultra series instead.

Buy this if you're building a virtualization host, a database server, or a rendering box that needs 32 cores and tons of cache. It's a productivity and server workhorse with best-in-class multi-threaded performance. If you're a gamer or casual user, this is not your chip. The power draw alone will make your electric bill cry.
