The NVIDIA DGX supercomputer using GH200 Grace Hopper Superchips could be the top of its class. Learn what this and the company’s other announcements mean for enterprise AI and high-performance computing.
On May 28 at the COMPUTEX conference in Taipei, NVIDIA announced a host of new hardware and networking tools, many focused around enabling artificial intelligence. The new lineup includes the 1-exaflop supercomputer, the DGX GH200 class; over 100 system configuration options designed to help companies host AI and high-performance computing needs; a modular reference architecture for accelerated servers; and a cloud networking platform built around Ethernet-based AI clouds.
The announcements — and the first public talk co-founder and CEO Jensen Huang has given since the start of the COVID-19 pandemic — helped propel NVIDIA in sight of the coveted $1 trillion market capitalization.

NVIDIA’s new class of AI supercomputers take advantage of the GH200 Grace Hopper Superchips, and the NVIDIA NVLink Switch System interconnect to run generative AI language applications, recommender systems and data analytics workloads (Figure A). It’s the first product to use both the high-performance chips and the novel interconnect.

NVIDIA will offer the DGX GH200 to Google Cloud, Meta and Microsoft first. Next, it plans to offer the DGX GH200 design as a blueprint to cloud service providers and other hyperscalers. It is expected to be available by the end of 2023.
The DGX GH200 is intended to let organizations run AI from their own data centers. 256 GH200 superchips in each unit provide 1 exaflop of performance and 144 terabytes of shared memory.
Specifically, NVIDIA explained the NVLink Switch System enables the GH200 chips to bypass a conventional CPU-to-GPU PCIe connection, increasing the bandwidth while reducing power consumption.
Mark Lohmeyer, vice president of compute at Google Cloud, pointed out in an NVIDIA press release that the new Hopper chips and NVLink Switch System can “address key bottlenecks in large-scale AI.”
“Training large AI models is traditionally a resource- and time-intensive task,” said Girish Bablani, corporate vice president of Azure infrastructure at Microsoft, in the NVIDIA press release. “The potential for DGX GH200 to work with terabyte-sized datasets would allow developers to conduct advanced research at a larger scale and accelerated speeds.”
NVIDIA will also keep some supercomputing capability for itself; the company plans to work on its own supercomputer called Helios, powered by four DGX GH200 systems.
Another new service, the NVIDIA AI Enterprise library, is designed to help organizations access the software layer of the new AI offerings. It includes more than 100 frameworks, pretrained models and development tools. They are appropriate for the development and deployment of production AI including generative AI, computer vision, speech AI and others.
On-demand support from NVIDIA AI experts will be available to help with deploying and scaling AI projects. It can help deploy AI on data center platforms from VMware and Red Hat or on NVIDIA-Certified Systems.

NVIDIA wants to help speed up Ethernet-based AI clouds with the accelerated networking platform Spectrum-X (Figure B).

“NVIDIA Spectrum-X is a new class of Ethernet networking that removes barriers for next-generation AI workloads that have the potential to transform entire industries,” said Gilad Shainer, senior vice president of networking at NVIDIA, in a press release.
Spectrum-X can support AI clouds with 256 200Gbps ports connected by a single switch or 16,000 ports in a two-tier spine-leaf topology.
Spectrum-X does so by utilizing Spectrum-4, a 51Tbps Ethernet switch built specifically for AI networks. Advanced RoCE extensions bringing together the Spectrum-4 switches, BlueField-3 DPUs and NVIDIA LinkX optics create an end-to-end 400GbE network optimized for AI clouds, NVIDIA said.
Spectrum-X and its related products (Spectrum-4 switches, BlueField-3 DPUs and 400G LinkX optics) are available now, including ecosystem integration with Dell Technologies, Lenovo and Supermicro.
In more news regarding accelerated performance in data centers, NVIDIA has released the MGX server specification. It is a modular reference architecture for system manufacturers working on AI and high-performance computing.
“We created MGX to help organizations bootstrap enterprise AI,” said Kaustubh Sanghani, vice president of GPU products at NVIDIA.
Manufacturers will be able to specify their GPU, DPU and CPU preferences within the initial, basic system architecture. MGX is compatible with current and future NVIDIA server form factors, including 1U, 2U, and 4U (air or liquid cooled).
SoftBank is now working on building a network of data centers in Japan which will use the GH200 Superchips and MGX systems for5G services and generative AI applications.
QCT and Supermicro have adopted MGX and will have it on the market in August.
NVIDIA announced a variety of other new products and services based around running and using artificial intelligence:
There aren’t many companies or customers aiming for the AI and supercomputing speeds NVIDIA’s Grace Hopper chips enable. NVIDIA’s major rival is AMD, which produces the Instinct MI300. This chip includes both CPU and GPU cores, and is expected to run the 2 exaflop El Capitan supercomputer.
Intel offered the Falcon Shores chip, but it recently announced that this would not be coming out with both a CPU and GPU. Instead, it has changed the roadmap to focus on AI and high-powered computing, but not include CPU cores.
