Have you got any compositing enabled?

Sorry I don't understand what you mean with that question. I loaded factory settings, and then I tried to render the default startup file's scene.

@mike w. (mikewazowski11) In properties Editor go to the Render tab and then Post Processing panel.
Disable the Compositing and Sequencer checkboxes.

Does that change anything?

Done. Still the same results, no object renders with gpu :/

Why is such a critical bug left unanswered for?

Could this be somehow related to T49620?

it actually looks pretty darn similar, the result, if there is, is simply wrong and not what it should be.

Try to check motion blur and then render again on GPU.

Tom, I tried checking motion blur as you said and GPU rendering worked as usual. That workaround seems to be doing the job.

What is your difference in rendering time with and without motion blur?

Well without motion blur the render time of a random scene is 19.28 seconds while the time with motion blur is 68.7 seconds. Although the low render time might be because of not rendering any object.

With motion blur it seems to work.

I downloaded the latest build (few days ago) and it works.
I can render with gpu. I am so happy :D Thanks!

Yes, but it doesn't work on new Relive drivers with 7xxx series.

I use the new (Relive) drive for the HD 7700 series because I reinstalled Windows.
