I am having problems getting posts and comments to go through. I will keep trying to get my actual question posted in a comment here.
It turns out the organization we got our sandbox from never used the water functionality and a quick check in the tower case explains why–whoever set up their system didn’t use a computer with a discrete GPU. So we need a graphics card. The computer guy we consult with recommended a card with these specs:
4GB, 128-bit, GDDR6
Boost Clock: 1620 MHz
Coprocessor: NVIDIA GeForce GTX 1650Will this card work?
I found this comment that may help for future GPU questions:
“As far as I am aware the only thing that matters is the number of cuda cores 1050ti has 768. Gtx 970 has 1664, 980=2043 980ti=2860 1060=1280 1070=1920 1080=2560, 1650=896 Cores. Other stuff does matter as 1080 is faster than 980ti but second hand cost means I have a 980ti”
If this is correct, your water simulation might go a little slow. But anyway it should work, as sean said.
Also, about memory differences:
“From my experience memory isn’t as important as pure processing power”In my case I’m using a 1060 3 GB instead of a 6gb without problems
Just to add another data point… Our sandbox has an Nvidia Quadro 2000. Released in 2010, it has 1 GB memory and 192 CUDA cores. The card was recovered from a campus CAD lab that was upgrading their hardware (i.e. free to us).
The only time I see slowness is when I flood the whole box with virtual water. Even four or five studens making rain does not burden the hardware.
Thank you for the additional info–I’ve added it to the documentation and that’s reassuring, Sean–our age range is elementary students so there’ll probably be multiple students at once as well.
Now if I can just get the driver installed…
Hello everyone.
I’m starting my second build in the next months and I’m evaluating the GPU.
For the first build I used a GTX 1060 with 6GB of RAM – 1280 CUDA cores.
Performance was ok, but i did notice some lag when a lot of water was simulated (big lake, broken dam, etc.)For this second one i’m considering a GTX 1660 Ti 6GB – 1536 CUDA cores.
Hopefuly it will run smoothly.Any thouhgts?
thanks!
Adnrei.
