I've ran a comparison benchmark for the smaller models https://gist.github.com/mhitza/f5a8eeb298feb239de10f9f60f841...

Comparing it against the RTX 4000 SFF Ada (20GB) which is around $1.2k (if you believe the original price on the nvidia website https://marketplace.nvidia.com/en-us/enterprise/laptops-work...). Which I have access to on a Hetzner GEX44.

I'm going to ballpark it between 2.5-3x faster than the desktop. Except for the tg128 test, where the difference is "minimal" (but I didn't do the math).
