A mysterious AMD Ryzen 9 CPU has been tested on the upcoming Medusa Point "Plum" platform in a new leak spotted at Geekbench.
Is This An ES Medusa Point? AMD Ryzen 9 CPU With 10 Cores & 32 MB L3 Cache Spotted On Next-Gen Plum REVB
Last year, AMD began rolling out its Plum "FP10" evaluation platform designed around the next-gen Medusa Point APUs. In the previous leak, the Plum platform was listed to feature 45W SoCs, and from new leaks, it looks like AMD is indeed testing out some new stuff.
A new AMD Ryzen entry has appeared at Geekbench, which lists a new mode with the "100-000001713-31_N" ID. This chip features 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 speeds. The CPU isn't clustered into standard and density-optimized cores, but that could also be due to the early nature of this chip, with Geekbench not able to identify the two sets of core designs. The CPU is mentioned as an AuthenticAMD Family 26 Model 128 Stepping 0 part.
The interesting part of this chip is the cache configuration. It looks like all 10 cores feature 1 MB of L2 cache, and the L3 cache is a singular 32 MB stack. Now, if we take the Ryzen AI 9 365 as an example, it features a similar 10-core and 20-thread design based on the Zen 5 core architecture, has 1 MB of L2 cache dedicated per core, but the L3 cache count is 24 MB. This means that the mysterious chip offers 50% more cache thab Strix/Goron processors.
When looking at the Geekbench log, the CPU is listed as an "AMD Ryzen 9" part and was running a balanced profile while the system featured 32 GB of memory. The memory type is not mentioned.
One can think that this could be a Medusa Point APU, but we will wait for more confirmation. What we can say is that the Plum platform is designed for FP10 Medusa Point chips, and more such IDs have been seen and spotted by Planet3DNow forum members:
As for Medusa Point, we know that the next-gen APU family will feature the latest Zen 6 cores for the CPU, a mix of RDNA 5 and RDNA 3.5 iGPU cores, and the latest NPU. The chips are expected to be unveiled at CES 2026, so we are still a year away from launch.
