A 4090 280W limit will perform similarly to its unlimited configuration on CUDA workloads. As another commenter said blower style fans are fine for this. The segmentation around NVLink is what makes this worthless. And anyway, they could equip it with 48GB of RAM, like the L40 part. It's all bullshit.

Just tried this, it's 30% slower.

24GB of GGDR6X is $$$$. Especially if they are double density chips, to keep the RAM on a single side, important for cooling!

Again, NVlink is not required for 99% of people.
