Mysterious 10-Core AMD “Ryzen 9” CPU with 32 MB L3 Cache Appears on Plum Platform for Medusa Point APUs

AMD Medusa "Ryzen" Client CPUs Reportedly Feature Zen 6 CPU & RDNA 5 Integrated GPU Cores 1

A mysterious AMD Ryzen 9 CPU has been tested in the upcoming Medusa Point “Plum” location in a new leak spotted on Geekbench.

Is This The Point Of ES Medusa? AMD Ryzen 9 CPU with 10 cores and 32 MB L3 cache shown in Next-Gen Plum REVB

Last year, AMD began introducing its Plum “FP10” test platform designed around next-generation Medusa Point APUs. In a previous leak, the Plum platform was listed to include 45W SoCs, and from the new leak, it looks like AMD is indeed testing new things.

A new AMD Ryzen installation has appeared on Geekbench, listing a new mod with the ID “100-000001713-31_N”. This chip includes 10 cores and 20 threads, with a base frequency of 2.40 GHz, but due to the ES nature of this chip, it was running at around 2 GHz clock speed. The CPU is not grouped into standard cores and improved density, but that may be due to the original nature of this chip, Geekbench can identify two sets of core designs. The CPU is referred to as an AuthenticAMD Family 26 Model 128 Stepping 0 component.

An interesting part of this chip is the cache configuration. It looks like all 10 cores have 1 MB of L2 cache, and the L3 cache is a single 32 MB stack. Now, if we take the Ryzen AI 9 365 as an example, it has the same 10-core and 20-thread design based on the Zen 5 core architecture, it has 1 MB of L2 cache dedicated to each core, but the total L3 cache is 24 MB. This means that the mysterious chip offers 50% more cache than Strix/Goron processors.

If you look at the Geekbench log, the CPU is listed as part of “AMD Ryzen 9” and was running on the balanced profile while the system included 32 GB of memory. The type of memory is not mentioned.

One would think this could be the Medusa Point APU, but we will wait for more confirmation. What we can say is that the Plum platform is built for FP10 Medusa Point chips, and many such IDs have been spotted and seen by Planet3DNow forum members:

As for Medusa Point, we know that the next generation APU family will include the latest Zen 6 CPU cores, a mix of RDNA 5 and RDNA 3.5 GPU cores, and the latest NPU. The chips are expected to be unveiled at CES 2026, so the launch is still a year away.
