Nvidia unveils the HGX-2, a server platform for HPC and AI workloads | ZDNet

While "replacing 300 CPU-only servers on deep learning training" is hardly a benchmark, 15,500 images per second on ResNet-50 is – just a couple of years ago, training throughput would be 1-2 orders of magnitude slower. Also of interest is the approach that Nvidia is taking here – a single compute "node" will be capable of delivering both AI and HPC workloads with extreme performance (the reference implementation claims two petaflops).
