New 344.48 WHQL driver released.
It is still using a 256bits bus, which I am not loving. It has less bandwidth than a 780Ti by a fair margin (224 vs 336). Even the 780 (not Ti), was running at 384 bits for 288GB/s of bandwidth.
Hopefully, since this is GM204, we will see a GM200 in the first Tesla product with a wider 384 bits memory bus.
384 bits would still be far short of the 512 bits memory bus of the GTX280!

Hi,
I have played around with CUFFT on both a titan black and gtx980, and the 980 is quite impressive.
I found some software called Nukadafft which includes a measure of time on gpu vs wall clock, you might want to check it out.
I am doing some work to improve the 3D FFT needed for molecular dynamics calcs, and so far the 980 is proving much faster than the titan black.

They expected 980Ti/Titan2 in Q4 2014.
I don’t know which rumors to believe, but there was one that hit the blogs a couple of days ago, and according to it, 980Ti/Titan2 shouldn’t be expected until 2016!
Nvidia's "big daddy" GM200 Maxwell chip is facing delays. Mainly due to TSMC's16nm manufacturing process, which has slipped 2 quarters so far

Hi Phil,
Could you share some more details on this? Im also very interested in 2d 32bit fft performance, but I see varying results. Some claim the smaller memory bus is limiting in cufft for Maxwell, resulting in much reduce performance (see: https://devtalk.nvidia.com/default/topic/782314/cuda-programming-and-performance/cufft-speed-on-gtx980/ ). But perhaps it depends a lot on the specifics?
I don’t have a Maxwell part yet, but could you share your findings in more detail?
