NVIDIA Tesla K40 Announced, Best Performance/Watt Solution

NVIDIA has launched its fastest GPU accelerator for computing servers. The Tesla K40 delivers up to 25% more performance compared to the Tesla K20X. AMD’s FirePro S10000 is still faster but with more power consumption…

NVIDIA Tesla K40 in numbers:
– 12GB of ultra-fast GDDR5 memory, 384-bit
– full GK110 GPU (Kepler) with 2880 CUDA cores
– core clock: 745MHz, boost clock: 875MHz
– TDP: 235W
– Price: around USD $5500
– Peak FP64 performance: 1.43 TFLOPS
– Peak FP32 performance: 4.29 TFLOPS

The Tesla K20X for the sake of comparison:
– 6GB of GDDR5 memory, 384-bit
