I have a co-worker that designs antennas. He and I did a comparison of his Dell Precision T3500 vs my custom build. His computer has 24gb and Xeon 8-Core. The GPU is an ATI Card, but the software is Cuda enabled.
In our comparison his computer took 18.5 hours to complete the calculations, while mine to 7.2 hours. I enabled Cuda to run on my GTX 770.
We want to go to our boss and state the case for a GPU upgrade for his computer, but I wanted to check here for suggestions on the path to take.
Do we need to change the PSU, the dell site
says up to 2 GPUs for a total of 150 Watts. Also what GPU should we suggest? I am thinking a GTX 780 Ti or something similar to really boost his performance. The card will only be used for calculating and as the output to the screen nothing else.
The program does allow double precision floating point, but since he has never used it I don't think that is relevant.
This is the site
for the program.
