Detailed AMD Medusa Halo and Medusa Halo Mini APUs leak claims up to 26 Zen 6 cores and next-gen RDNA 5 iGPUs
After releasing the next-generation Zen 6 CPUs and RDNA 5 GPUs in the second half of 2026, AMD is expected to launch the Medusa Halo laptop APU in H2 2027. Mimicking the Strix Halo approach, the Medusa Halo APU reportedly employs a powerful Zen 6 CPU and a capable RDNA iGPU. Moore’s Law Is Dead previously revealed that the Medusa Halo’s iGPU could be based on the next-gen RDNA 5/UDNA graphics architecture with up to 48 Compute Units and a 384-bit bus.
The leaker has now leaked more Medusa Halo specs. Additionally, the leaker has also confirmed the Medusa Halo Mini, the smaller sibling of the Halo SKU with fewer CPU and GPU cores.
AMD Medusa Halo APU specifications
Starting with the more powerful Medusa Halo APU, MLID claims that the APU features 12x Zen 6 cores and 2x Zen 6 LP cores. There is a possibility that the APU could have an additional 12-core Zen 6 CCD, resulting in a total of 24 big cores and 2 low-power cores. The 12-core CCD(s) are expected to be based on TSMC’s cutting-edge 2nm N2P, while the IOD containing the LP cores is said to utilize the 3 nm N3P node.
For the memory subsystem, MLID alleges a 384-bit LPDDR6 or a 256-bit LPDDR5X memory controller. This is in line with the leaker’s previous reporting.
Medusa Halo’s iGPU is, perhaps, the most interesting part of the whole package. The iGPU is reportedly based on the RDNA 5 architecture with 48 CUs and, possibly, 20 MB of L2 cache. There is a chance that this 48-CU iGPU, however, is actually the same one that AMD plans to use in the discrete RDNA5 “AT3” desktop GPU.
AMD apparently plans to use the exact GPU chiplet die from a discrete RDNA 5 card, possibly the 1060XT. While the name of this discrete RDNA 5 board remains under wraps, MLID also alleges a ton of details about the GPU, which we have covered in a separate article.
AMD is also said to employ this strategy of using a desktop GPU die for a mobile APU in the Xbox Magnus APU.
AMD Medusa Halo Mini APU specifications
For the Medusa Halo Mini APU, AMD is allegedly planning a 14-core CPU with 4x Zen 6 cores, 8x Zen 6c cores, and 2x Zen 6 LP cores. This CPU is paired with a 128-bit LPDDR5X memory controller. The leaker claims that there is a chance that a wider 192-bit wide LPDDR6 could make the cut.
Finally, the Medusa Halo Mini, like its bigger brother, reportedly packs the “AT4” RDNA 5 desktop GPU chiplet as its iGPU. This iGPU allegedly brings 28 CUs and 10 MB of L2 cache.
Sadly, MLID hasn’t revealed any performance figures for the Medusa Halo and the Medusa Halo Mini APUs. However, the leaker has given some performance projections for the discrete AT3 and AT4 RDNA 5 GPUs, which could give some indication of the graphics capabilities of these Zen 6 APUs.
The Medusa Halo and the Medusa Halo Mini are rumored to show up in 2027, at the earliest. So, this should tell you to take the leaked specs with a healthy dose of skepticism.
