Patents show AMD’s post-Navi GPU could use an nVidia-like architecture - Gigi je u nekoliko navrata spomenul Super-SIMD, a AMD bi u prijevodu lako mogel spremiti Ryzen GPU ekvivalent.

This is a new take on the stream processor for the GPU architecture to follow it, potentially in 2020. There has been speculation that AMD Arcturus would be the 7nm+ design on its current GPU roadmap, suggesting a 2020 launch for this whole new graphics processor design. The standard SIMD in the current Graphics Core Next architecture simply contains 16 arithmetic logic units (ALUs) and each compute unit (CU) has four of these SIMDs inside it. This is is essentially what gives us the 64 ‘cores’ that we talk about when we say the Radeon VII has 3,840 GCN cores in it, for example. In the GCN architecture the compute unit is the smallest, fully independent, unit in the GPU.

The new high-bandwidth stream processors seem to have far more logic packed inside them than just the old GCN-style of simple ALUs. The patent shows each stream processor looking more like a GCN compute unit of old, with each of them housing their own instruction queues, cache and buffers. This could result in each ‘core’ then becoming the smallest independently functioning part of the GPU as they will be more capable of carrying out tasks without having to wait to use the shared resources built into the standard compute unit. The previous application has a diagram of what the updated compute unit design would look like when housing four of the more complex stream processors, which can then farm completed tasks out to the scheduler and shared cache of the next-gen CU.
