I´m thinking of upgrading my computer a little with a new graphics card. Right now I´m working with an old GTX 660 TI, which is regarding to its age, quite ok.
My preferred GPUs right now are a RTX 2060 and RX 5700, so 6 GB vs. 8 GB. I don´t want to spend too much money on it (I managed to work and play with my 660TI for 8 years now ), because it´s just one of many hobbies of mine! Perhaps a RX 5600 XT is also sufficient as it´s more or less a 5700 with only 6 GB.
RTX 2060 Super is faster than 5700 and features raytracing hardware. The non super variant is a little slower but again features raytracing hardware. As of right now there is absolutely no reason to go with AMD. Interesting to see if the next gen cards will change that.
So, got my RTX 2060 KO yesterday and intstalled it today. Here are my quick benchmark resuts:
BMW, Blender 2.83
GTX 660 TI (Cuda): 4min30sec
RTX 2060 KO (Cuda): 1min16sec
RTX 2060 KO (OptiX): 36sec
GTX 1650 (Laptop): 2min30sec
I´m pretty happy with the result! What do you think?
Even my laptop is ok for the renderjobs, but its CPU temperature rises very high during rendering (~ 95°C) and I dont want to torture it too much. Even if I only use GPU for rendering. Is this normal?
Awesome, the RTX cards are a lot of fun. Your CPU overheating sounds like you have cooling issues with your case or CPU cooler. Adding in the 2060 might have overwhelmed your current case cooling. You might want to look at a new CPU cooler or adding a fan or two to your case if it has room for them.
he is talking about a laptop there. Under a sustained load it’s not surprising. But yeah if it’s old enough it’s probably worth cleaning the dust out of it and changing the TIM.
You´re right, I was talking about my laptop. Well, it´s rather new. Just bought it about 6 months ago. So there shouldn´t be too much dust. I only wonder why the CPU load is at 100% during rendering, even if I only check the GPU in preferences. Perhaps I should start another topic for this!?
I´m going to render on my PC with the RTX now and keep modeling on my laptop, as it works pretty nice and smooth there
It might be the CPU is feeding data to the GPU, and if the frame is quick to render for the GPU then the CPU stays busy feeding new data to the GPU for the next frame.
I have the RX 5700. I am having massive issues getting cycles rendering to work. So far I can only get it stable in 2.80. 2.83 seems a bit better not tested it properly yet but it seems slower. Basic cube rendering at 48 seconds in 2.8 and 1.50 in 2.83. Not sure if it is my settings but it’s basically out of the box New file then render in both versions.
Generating render kernels for the first time crashes Blender pretty much every time in anything other than 2.8 so far. Just a heads up, might be just my system though, but I have seen this issue around the internet.
Better not to imagine things and report anyway. Or at least you look for some of those reports with similar problems and you participate there by providing data from your GPU, OS, driver version and the problem in general.

Thanks, like i said, laptops are not on my radar at all.
