AMD Ryzen AI Max+ Pro 395 spotted in the wild
AMD's fastest combined processor for notebooks and mini PCs combines 16 CPU cores with a powerful GPU.
An old Ryzen 4000U, which is still monolithic. The Ryzen AI 300 Max, on the other hand, should consist of three chiplets.

A first public benchmark of a previously unveiled processor indicates its imminent announcement. An AMD model with the rather unwieldy name Ryzen AI Max+ Pro 395 has appeared in the Geekbench benchmark – presumably the top model from the new Strix Halo family.
Its existence is considered an open secret; an announcement would be conceivable at the CES electronics trade fair in early January 2025. On January 6 at 20:00 German time, company boss Lisa Su will give a keynote speech to kick off CES.
Many arithmetic units with plenty of cache
Strix Halo is to be positioned above the previous Strix Point aka Ryzen AI 300. The Geekbench entry (via Videocardz) now further substantiates the various consistent rumors: Like the Ryzen 9000 desktop processors, the Ryzen AI Max+ Pro 395 is to receive 16 fully-fledged Zen 5 cores with a total of 64 MByte level 3 cache. The CPU cores are presumably distributed across two compute chiplets.
While a third chiplet in the desktop models only contains a mini graphics unit in addition to the memory controllers and I/O functions, Strix Halo is to receive a much more powerful GPU. There is talk of 40 compute units (2560 shader cores) with RDNA 3.5 architecture. Geekbench calls the GPU Radeon 8060S – closer to the standalone graphics chips. Stand-alone entry-level GPUs should therefore become superfluous. For comparison: The fastest Ryzen AI 300s to date have 1024 shaders.
The only weak point could be the memory transfer rate. The benchmark notes four DDR5 channels, so presumably a 256-bit wide interface. Fast high-bandwidth memory (HBM) is probably too expensive for notebooks and mini PCs with the Max processors.

Test result not meaningful
The Ryzen AI Max+ Pro 395 was put through Geekbench's Vulkan GPU test. The 67,000 points achieved are nominally below the result of the current entry-level graphics card Radeon RX 7600, which also achieves more than 90,000 points depending on the clock frequency.
However, the Ryzen result is not very meaningful: even the DDR5 4000 memory used slowed down the system. There are also question marks over the firmware version and the cooling system used.
