Haha running OSS-120B on my 5090 with most of the layers in video memory, some in RAM with LM Studio, I was hard pressed to get it to actually use anywhere near the full 600W. Gaming in 4K playing a modern game generates substantially more sustained heat.

This looks like it’ll run easily on a Strix Halo (180W TDP), and be a little sluggish on previous gen AMDs (80W TDP).

I can’t be bothered to check TDPs on 64GB macbooks, but none of these devices really count as space heaters.

For the record, a typical US space heater is 1500 W. We're talking a small fraction of a space heater.

(Not that I'd want one in my office in the summertime, but I also wouldn't want the fan noise.)
