All AMD Zen 4, including the laptop 7x4x and 8x4x series support bfloat16 too.

The laptop models also include a separate ML/AI inference accelerator besides the CPU and GPU, but for now that has software support only for Windows.

If I recall correctly, these integrated "AI accelerators" from both Intel and AMD are actually rather underpowered in comparison to an actual GPU (even the iGPU), at least in their current forms. So they don't have any performance advantage, but was put in place for power efficiency.

The new amd agpus are on par.
