No. Memory bandwidth is the important factor for LLM inference. 64GB/s is 4x less than the hypothetical I granted you (Gen7x16 = 256GB/s), which is 4x less than the memory bandwidth on my 2 year old pleb GPU (1TB/s), which is 10x less than a state of the art professional GPU (10TB/s), which is what the cloud services will be using.
That's 160x worse than cloud and 16x worse than what I'm using for local LLM. I am keenly aware of the options for compression. I use them every day. The sacrifices I make to run local LLM cut deep compared to the cloud models, and squeezing it down by another factor of 16 will cut deep on top of cutting deep.
Nothing says it can't be useful. My most-used model is running in a microcontroller. Just keep those expectations tempered.
(EDIT: changed the numbers to reflect red team victory over green team on cloud inference.)
