They now have Xilinx's AI cores since they merged (acquired?). https://www.xilinx.com/products/technology/ai-engine.html https://www.xilinx.com/products/technology/ai-engine.html seems to be a high-level overview. I think their latest APUs for laptops have this IP integrated. And they're blurring the line by adding more AI-focused acceleration instructions to their GPUs (maybe focused on their CDNA line rather than the consumer RDNA, but they're expanding their capabilities on both). There seems to be a bit of a philosophy difference between NVidia and AMD acceleration - NVidia add new specialised "cores", while AMD adds those similar capabilities as accelerated instructions to their shader units. Though this might just be marketing - I don't think we've got an open reference for the NVidia shader ISA like we do with AMD so difficult to compare, but the capabilities and integration in shaders of many of these acceleration paths seems to imply they might also be implemented as shader instructions, which stretches the definition of a separate "core" to me, and so might just be a marketing difference rather than anything technical. Same with things like the BVH acceleration used in ray tracing - AMD added shader instructions, while NVidia talks loudly about "RT Cores".
