Nearly six months in the past, Nvidia’s spring GTC occasion noticed the announcement of its hotly anticipated Hopper GPU structure. Now, the GPU large is asserting that Hopper-generation GPUs (which promise better vitality effectivity, better energy and decrease TCO) are in “full manufacturing” and disclosed further particulars concerning availability — on-prem and in-cloud — of the brand new {hardware}.
The quick model: companion techniques that includes the Nvidia H100 GPU (from Atos, Cisco, Dell, Fujitsu, Gigabyte, HPE, Lenovo and Supermicro, amongst others) are slated to start transport in October — a slight slip from Nvidia’s Q3 transport estimate from that spring GTC announcement. PCIe-based techniques can be made obtainable first, adopted by NVLink HGX platforms later within the 12 months. (Nvidia attributes this delay to not part availability, however relatively to the complexity of the HGX answer relative to PCIe options.) In the meantime, DGX techniques that includes the H100 — which had been additionally beforehand slated for Q3 transport — have slipped considerably additional and at the moment are obtainable to order for supply in Q1 2023.

On that entrance, only a couple months in the past, Nvidia quietly introduced that its new DGX techniques would make use of Intel’s forthcoming Sapphire Rapids CPUs — a shift from the AMD Epyc CPUs that had powered their prior-generation (A100) techniques. These Sapphire Rapids CPUs have been much-delayed from their preliminary ship date projection (2021) and now look like slated for manufacturing ramp in Q1 of subsequent 12 months. Different targets for the H100 embody AMD’s forthcoming Epyc Genoa CPU (additionally slated for subsequent 12 months) and Nvidia’s personal Arm-based Grace CPU (you guessed it — subsequent 12 months). The H100 could also be in “full manufacturing,” however its major CPU counterparts can be racing to catch up.
Nonetheless, there can be different methods to make the most of the brand new Hopper GPUs. Nvidia introduced that the H100 (housed in Dell PowerEdge servers) is now obtainable on Nvidia LaunchPad, which lets customers check out Nvidia’s {hardware} and software program stacks in a short-term, hands-on trial surroundings. The H100s are additionally making their method to the cloud, after all, with Nvidia asserting that AWS, Google Cloud, Microsoft Azure and Oracle Cloud Infrastructure will all be “among the many first” to deploy H100-based situations someday subsequent 12 months.
On the analysis entrance, main supercomputers set to debut the H100 embody Alps (CSCS), MareNostrum 5 (Barcelona Supercomputing Heart), Venado (Los Alamos Nationwide Laboratory), the tentatively named Cygnus-BD system (College of Tsukuba) and the already-operational Lonestar6 system on the Texas Superior Computing Heart. A few of these techniques will incorporate the H100 by way of Nvidia’s forthcoming Grace Hopper Superchips, which can function tightly linked Grace CPUs and Hopper GPUs.
The techniques deploying the H100 will get pleasure from drastic enhancements over the already-popular A100, which has develop into the de facto commonplace of comparability over the previous couple of years amid fierce and rising accelerator competitors from established giants and specialist startups. The H100, Nvidia says, delivers 30 teraflops (FP64) of computing energy (examine: 9.7 for the A100) and affords 3.5× extra vitality effectivity and three× decrease TCO relative to the A100. (Be aware: the PCIe model of the H100 delivers 24 FP64 teraflops relatively than 30.)
“Nvidia is on observe to make Hopper essentially the most consequential datacenter GPU ever, partly due to the 5× efficiency increase for giant language fashions, however extra due to the ever-broadening array of software program for business and the enterprise,” commented Karl Freund, founder and principal analyst at Cambrian AI Analysis. “There are lot of corporations on the market simply attempting to match Nvidia’s efficiency; they haven’t even begun to handle the deep and broad software program stack that turns all these transistors into options.”
To Freund’s level, Nvidia additionally introduced at the moment that it has begun optimizing main massive language fashions and deep studying frameworks on the H100, together with Microsoft DeepSpeed, Google JAX, PyTorch, TensorFlow, XLA and Nvidia’s personal NeMo Megatron.
