Hello!
Since someone was asking a few days back regarding performance of Kepler
GPUs, here are some benchmarking results. This is with the
Linux-x86_64-multicore and Linux-x86_64-multicore-CUDA builds of NAMD
2.9 as downloaded from the NAMD website, on a system with i5-3570 CPU
and Intel H77 chipset and a GTX-660 TI graphics card. Power consumption
with GPU acceleration is about 200 W.
The last three are from the Daresbury benchmark suite, download here:

Timing results in s/step.
NAMD NAMD-CUDA
ApoA1 (90K atoms) 0.187 0.038
F1ATPase (330K atoms) 0.537 0.136
STMV (1M atoms) 2.351 0.472
GlnBP (61K atoms) 0.140 0.030
EGFR-flat (465K atoms) 1.136 0.267
EGFR-tall (1.4 M atoms) 3.421 0.755
