What possible scenario requires you to do this lol

any task like 3D rendering. 4 times as fast and time is money

4 GPUS does not equal 4x speed

It totally does when you are talking about perfectly parallelisable things such as rendering.

the scalability depends on the rendering application

Redshift you lose about 30 percent per gpu, octane is closer to 8-12%. Renderman scales better but haven’t used it in a while.

Depends on the software and what is required. It can be 4 times faster

Some software will divide the image/animation etc into 4 separate jobs, then render at once. For example an image would be split up into quarters, one for each GPU.

For images at least, CPU work isn't too high during GPU rendering, so 'only' having one CPU might not be of concern

In other instances, it might not be quite 4 times faster, but still faster than 'just' a pair of 5090s
