On the NVIDIA web site it is repeatedly stated that double precision is supported as of compute level 1.3. However, I can’t figure out what exactly “supported” means. I have read on other forums that only a fraction of the GPU’s resources support double precision operations. Can someone explain this to me?
To put this question into context: I’m in the market for a graphics card that will speed up the experiments I’m running as part of my graduate studies. The experiments involve a lot of matrix operations where all the values are of type double. Right now it takes about 2 days to run a single experiment and I’m hoping to trim that down. It’s not something that would be running constantly, more like once or twice a week. I was looking at the GTX 660 ti and heard it’s not very good for double precision operations but again I don’t know what “not very good” means.
