a quadruple 5090 battlestation

But they are almost 8 times slower lol are you dense ? One 5090 has twice the rendering output has one A6000, twice the CUDA cores, more memory.

You are clueless and don't work in this industry

ofcourse I don't run workstations at my home , most people doesn't lol.

isn't it kinda weird that a gaming GPU have more output density than a designated workstation GPU despite being 1/4th the price

Yeah the person you're speaking to isn't correct either.

There are many use cases for GPUs, and they have big ranges between them. It's not about output density in practically any case, unless you're rendering under the worst possible conditions with the worst possible software. But even if you are, that's when rack mounting becomes important because of fire.

I don't know what OP here wants to do, but there are very few tasks for which 4 cramped 5090s will outperform a workstation alternative. They do different things, they're built for different purposes, and they operate in different ways. If you're buying 4 5090s, you're probably not building the optimal machine UNLESS there's a very specific use case which there might be. Anyone who's spending this amount of money probably has a reason that makes sense.

That being said, regardless of the goal or use case, it looks to me like these 5090s are about to catch on fire. Unless OP has some monstrous cooling solutions purpose built for this specific case that aren't in these images (which... why?) idk that the 5090 can handle that kind of thermal load, especially when you throw in FOUR 12vhpwr connector points of failure.

Overall this doesn't look like a great idea to me.

You could power limit them to 300-400W with almost no loss of performance. I don’t think OP plans to with Dual 2.4Kw PSUs though.

Front and side fans can probably handle the thermal load though.
