alt Hacker NewsPC desktop chips have 128 bit busses to right ? From what I know theoretical maximum memory bandwidth of chips is less than 100gbps - which is less than like base M5/M4 chips.
So no matter how much compute you stuff in there it's going to be shit for AI ?
PC architecture is not adapting to AI workloads at all, and no signs of that changing in years to come. I would not be surprised if your phone was more capable of running AI models than an average desktop - especially given gpu pricing.
Apple has their high-bandwidth chips, the rest of the commercial desktop market is effectively running Windows, and Microsoft has no incentive to move towards local AI, their ideal case is that you use their cloud-based services and pay for them forever (you being enterprise clients with thousands of PCs).
