Blender has a benchmark page, and there are numbers all over the place, you can't tell what's a real benchmark.

These videos show people rendering using a 3070 etc., and you can see how long. 

Inspiration

This guys planets look awesome.  Sam Krug  He has some details on how he did these in blender also.

Reference

Here is a great reference of a spaceship done right.  Notice the details that give the ship a sense of scale, the running lights, the spotlights, the nurnie shapes.  The shot with pool window tells us something about the size, we know how big pools are.  The planet looks good and they have a lot of the blue atmosphere at the edge of the planet.  The rings are weirdly placed but look good.  The pod thing has great heat effects, and that's good compositing.
