A recent Microsoft paper proposed that the "perfect" inference machine is a ton of large-ish, modestly clocked, SRAM heavy chips piped together on a motherboard.
There is no RAM. The model weights are split up between the chips, and operations are pipelined like they already are in llms that are split into "layers". And there is no expensive interposer, or crazy interconnect like Cerebras. The chips are just wired together on a cheap motherboard, as the bandwidth between layers is relatively modest.
...It seems like this would work for training too. But what do I know? If it doesn't, the next "ideal" architecture is probably Cerebras's wafer-scale machines. And I am thinking they make use of TSMC's TSV tech (like AMD's X3D chips) to cram more SRAM onto a single wafer.
Theres also some fuss asserting that doing a bunch of matrix multiplication is an inefficient way to emulate physical neural networks, so maybe future architectures will be radically different?
- nimish 3y agoCerebras' strategy is the winner then if hardware was all that mattered
- brucethemoose2 3y agoYeah, I guess in the reality the perfect hardware is "an Nvidia GPU with sufficient VRAM" because its everywhere and already works by default.
