videocardz AMD patents GPU chiplets

[ENTERPRISE]

Quote

A new patent submitted to the US Patent Office on December 31 describing the AMD approach to potential GPU chiplet design. The manufacturer has outlined the problematic structure of such a design and explained how it would be possible to avoid them in the future.

According to AMD, the GPU designs have been kept in a monolithic state due to various problems with implementation. GPU programming model is inefficient to work with multiple GPUs (that also describes Crossfire configurations), as it is hard to distribute parallelism across multiple active dies in the system. It is also complex and expensive design-wise to synchronize memory content across multiple GPU chipsets, AMD describes.

Well it worked great for Zen, so why not a GPU !

Yeah, as discussed this before ( >here) ...Intel's multi-tile Xe HPG has shown a lot of promise already, and it doesn't surprise me one bit that AMD and NVidia will follow suit; multi-chiplet tech just makes way too much sense, also from a production yield cost / benefit pov. Never mind AMD's design lead via years of multi-chiplet Ryzens and InfinityFabric. The 'connectivity' between tiles and making them appear homogeneous to the rest of the system and apps is really the biggest challenge, but one which looks to be surmountable 

 

As you know, I have been using the undocumented 'proto Neanderthal' tile driver (CFR) wherever I can with my 2x 2080 Tis...not quite the same thing, but full of promise already !

Yeah I remember you calling it To be honest when going with a chiplet design, AMD should have this in the bag considering there experiences already with multiple generations of Ryzen. Perhaps there next gen will give Nvidia a real challenge.
