If this thing only has as much gpu bandwidth as the spark, it’s kinda pointles
My M5 Max 128gb MBP decodes faster than one of my Sparks, but the Spark's prefill is so much faster it can often answer the same query before the mac's prefill is finished. If you have large prompts, low cacheability, etc., a spark might be a very good options.
Not to mention you get can get two sparks and the MBP will be 85%+ of the cost at half the RAM.
I'm kind of tempted to pick one up. Leave running big models to my dual dgx setup, and all the misc. random stuff on an rtx.
Seems niche to be both uncacheable and long context?
Anywhere where you might have a large backlog of data to work with can end up in this sort of situation.
