GPUs

I need to purchase a GPU workstation for my lab.  Could you share your views on the following two options? I need to pick one for the ordering. Thanks, -- Hong

I did a little bit of investigation.

https://www.notebookcheck.net/Quadro-RTX-5000-Laptop-vs-GeForce-RTX-2080-Ti-Desktop_9852_9526.247598.0.html (performance about representative benchmark problems)

Please see the above links, which compare RTX 5000 with RTX 2080Ti. Seemingly 2080Ti outperforms 5000.

Therefore, I prefer Option 2.

One machine uses Quadro-branded GPU and the other uses GeForce-branded GPU. According to the following wikipedia link:

https://en.wikipedia.org/wiki/Nvidia_Quadro

"The GPU chips on Quadro-branded graphics cards are identical to those used on GeForce-branded graphics cards. The Quadro cards differ substantially in their ECC memory and enhanced floating point precision, which tremendously reduce the risks of calculation errors. " So it seems that Quadro has better performance in satisfying high requirement on computation accuracy than GeForce.

Also, on the same page, it says

"A Geforce card focuses more on texture fillrates and high framerates with lighting and sound, but Quadro cards prioritize wireframe rendering and object interactions."

Maybe that's why GeForce is listed more suitable for gaming, as shown in Usage Specific GPU on this page
