The new Maxwell 970/980 kit is very interesting from a compute perspective. 970: $329 for 3494 SP / 109 DP GFLOPS @ 145W TDP 980: $549 for 4612 SP / 144 DP GF

If the article is correct (saying that the memory bandwidth is very important) then a 780Ti is still interesting (336GB/s[1] vs 224GB/s[2]). They increased the memory clock but they decreased the memory interface width from 384 to 256-bit, for some reason.

  nVidia released the first level cutdown (GM204) as the "80" part, while it really should be the 960 at most - the full/big Maxwell core hasn't been released yet. Chances are the first fabbed version simply didn't work and they're waiting for the GM210.

Hmm. I am thinking about to get additional two GPUs for my configuration. 980 indeed sounds interesting, but the memory is too small. Any rumors about when NVIDIA plan to release a 6G+ card at similar price point as Titan?

  No rumors, but it would make sense to come out about a year after they released the Titan black, which itself was about a year after they released the original Titan.

Anandtech has some compute benchmarks for the 980: http://www.anandtech.com/show/8526/nvidia-geforce-gtx-980-review/20 http://www.anandtech.com/show/8526/nvidia-geforce-gtx-980-re... unfortunately I don't know which of these are representative of typical deep learning workloads, i.e. lots of GEMM calls, basically. A discussion about this is ongoing on the G+ Deep Learning community as well: https://plus.google.com/+SanderDieleman/posts/7ua9oCdRFV7 https://plus.google.com/+SanderDieleman/posts/7ua9oCdRFV7 This thread on the NVIDIA forums is also interesting, someone mentions they achieved > 6 TFlops for SGEMM on an overclocked GTX 980: https://devtalk.nvidia.com/default/topic/776043/cuda-programming-and-performance/whats-new-in-maxwell-sm_52-gtx-9xx-/2/ https://devtalk.nvidia.com/default/topic/776043/cuda-program...
