nVidia Titan X vs. nVidia Tesla K40 for programming.

[ace5968]

Ok so i'm looking for a new GPU and use also CUDA for programming. But does more CUDA means much faster GPU computing? By the way i'm not gonna use the gpu for gaming but instead use it for programming. So is tesla k40 better than titan x or is titan x better than the k40.

Is FP 64 compute important to you? The Titan X is not very good at that. Even the Titan Black is better at FP64 math from what I am hearing. What sort of programming are you doing?

R9 280X is the budget entry point for FP64 math. Tesla K40 is better if you want something with CUDA specifically designed for high compute scores although its more than double the price of a older Titan Black.

Maybe consider a cheaper Quadro K6000 compared to the crazy expensive Tesla card. There is a converation here on Tom's Harware about it all http://www.tomshardware.com/answers/id-2257445/quadro-k6000-tesla-k40.html

I would get a regular Titan as it is cheaper than a black, can be found for $500 used AND has higher FP32 and FP64 than the K40. The problem is I don't know how well nvidia supports development on non pro cards (aka any "gaming card"). The K40 is a Titan Black with also unlocked FP64 and 12GB of ram

The Quadro K6000 is a Titan Black I believe with ECC memory and Quadro Drivers

How about AMD Firepro series? You can get something solid in that range cheaper than a Titan.

Got to say though, the old cheap R9 280X idea might not end up being so bad.

7970GE was rebranded to R9 280X.

I think the k6000 is the best choice for my upgrade, thx btw
