LLM inference decode is heavily dependent on memory speed, not just having lots of memory. You can't say "X amount of ram" because the memory bandwidth on an M1 is 68.3 GB/s versus the 614 GB/s of an M5 Max, or a 4090's 1.01 TB/s over GDDR6X.

This basically creates a bottleneck at the oldest/cheapest Apple Silicon machines, which are already crippled for context prefill.

Thanks for clarifying -- I was oversimplifying.

But honestly, obsoleting a huge number of otherwise great Apple Silicon machines is something Apple would moment consider a major "pro" of building a compelling local AI stack.

With how much speculation around the difficult time Apple has had getting people to upgrade from M1, I'm sure they'd jump at such an opportunity.

this might be a way for Apple to milk product revenue for many years.

- Please buy our new Macbook pro M5 that gives you 20 tokens/s on local 80B LLM

next year - Please buy our new Macbook pro M6 that gives you 25 tokens/s on local 80B LLM

milking product revenue in perpetuity by offering meaningful marginal improvements, while keeping same architecture will be the golden goose for Apple

+plus if it allows to segment market by wallet size into poor/middle/rich classes, thats even better
