AMD Ryzen AI MAX 300-series processors, codenamed "Strix Halo," have been on in the news for close to a year now. These mobile processors combine "Zen 5" CPU cores with an oversized iGPU that offers performance rivaling discrete GPUs, with the idea behind these chips being to rival the Apple M3 Pro and M3 Max processors powering MacBook Pros. The "Strix Halo" mobile processor is an MCM that combines one or two "Zen 5" CCDs (some ones featured on "Granite Ridge" desktop processors and "Turin" server processors), with a large SoC die. This die is built either on the 5 nm (TSMC N5) or 4 nm (TSMC N4P) node. It packs a large iGPU based on the RDNA 3.5 graphics architecture, with 40 compute units (CU), and a 50 TOPS-class XDNA 2 NPU carried over from "Strix Point." The memory interface is a 256-bit wide LPDDR5X-8000 for sufficient memory bandwidth for the up to 16 "Zen 5" CPU cores, the 50 TOPS NPU, and the large 40 CU iGPU.

Golden Pig Upgrade leaked what looks like a company slide from a notebook OEM, which reveals the iGPU model names for the various Ryzen AI MAX 300-series SKUs. Leading the pack is the Ryzen AI MAX+ 395. This is a maxed out SKU with a 16-core/32-thread "Zen 5" CPU that uses two CCDs. All 16 cores are full-sized "Zen 5." The CPU has 64 MB of L3 cache (32 MB per CCD), each of the 16 cores has 1 MB of dedicated L2 cache. The iGPU is branded Radeon 8060S, it comes with all 40 CU (2,560 stream processors) enabled, besides 80 AI accelerators, and 40 Ray accelerators. The Ryzen AI MAX 390 is the next processor SKU, it comes with a 12-core/24-thread "Zen 5" CPU. Like the 395, the 390 is a dual-CCD processor, all 12 cores are full-sized "Zen 5." There's 64 MB of L3 cache, and 1 MB of L2 cache per core. The Radeon 8060S graphics solution is the same as the one on the Ryzen AI MAX+ 395, it comes with all 40 CU enabled.We now get to what will probably go down as the most popular processor SKU from the "Strix Halo" series, the Ryzen AI MAX 385. This processor comes with an 8-core/16-thread "Zen 5" CPU using a single CCD, all 8 of these are full-sized "Zen 5," share a 32 MB L3 cache, and have 1 MB of L2 cache per core. The iGPU is branded Radeon 8050S, and is configured with 32 CU (2,048 stream processors), 64 AI accelerators, and 32 Ray accelerators.

Lastly, there's the Ryzen AI MAX 380, the entry-level to this series. It comes with just a 6-core/12-thread CPU using a single CCD, but all six of these are full-sized "Zen 5," and have 32 MB of L3 cache on tap, besides 1 MB of L2 cache per core. AMD hasn't decided on what to call the iGPU solution, but it's configured with just 16 CU—the same number as the iGPU on the "Strix Point" monolithic silicon. Perhaps the advantages the Ryzen AI MAX 380 offers over the Ryzen AI 9 HX 370 is the fact that it has more full-sized "Zen 5" cores. The HX 370 has a 12-core/24-thread CPU, but 8 out of 12 of these are low-power "Zen 5c" cores that run in a lower frequency band than the "Zen 5" cores, and have a lower L3 cache share in their CCX.

We're not sure if all four processor SKUs get the 256-bit LPDDR5X memory interface, it's possible that the entry-level Ryzen AI MAX 380 comes with a narrower memory interface like 128-bit or 192-bit.
