I have a very similar setup, 3x4090s. Depending on the model I’m training, the GPUs use anywhere from 100-400 watts, but don’t get much slower when power limited to say, 250w. So they could power limit the 5090s if they want and get pretty decent performance most likely.
The cat loves laying/basking on it when it’s putting out 1400w in 400w mode though, so I leave it turned up most of the time! (200w for the cpu)
- jiggawatts 2y agoMay I ask what you’re training? And why not just rent GPUs in some cloud?
- buildbot 2y agoAccording to Weights & Biases, my personal, not work related account was in the top 5% of users, and I trained models for a total of nearly 5000 hours - so if I rented equivalent compute to this machine, I’d probably be out 5-10k so far - so this machine is very close to paying for itself if it already hasn’t. Also, not having to do the environment setup typically required for cloud stuff is a nice bonus.
