The most powerful NVIDIA datacenter GPUs and Superchips
In addition to popular customer segment video cards known under the brand GeForce, NVIDIA makes energy and space efficient GPUs intended for running in datacenters and powering training and inference of generative AI models. Space efficiency means that many GPUs are supposed to be installed in a single server and to make that possible, datacenter GPUs do not have fans and rely on server’s fans to cool them.
Datacenter GPUs boast a lot of memory and can be connected using NVLink, a technology that allows GPUs to exchange data lightning fast when many GPUs are used to train a single large model. Not all GPUs can be plugged into a motherboard of a PC or regular server. While there are some GPUs that have PCIe interface, usually only a pair of such GPUs can be connected using NVLink. NVIDIA has introduced an SXM (Server PCI Express Module) interface for powerful GPUs, which can be used to connect multiple GPUs using NVLink.
Furthermore, NVIDIA GPUs with SXM interface do not require an additional cable to provide them with enough power, they can draw all required power, up to 700 W from the interface. Also, horizontal mounting of the GPUs with SXM interface allows for easier cooling. The GPUs with this interface are intended for training of large models while GPUs with PCIe interface are intended more for inference workloads but can be used to train small models as well.
Understanding the type of the interface is important whether you rent datacenter GPUs or build your own workstation. If you need more than two GPUs connected using a fast link, your choice is renting GPUs with SXM interface. If you would like to install an older datacenter GPU which offers a good price for a gigabyte of memory into a regular server or PC you should shoot for a GPU with a PCIe system interface.
The GPUs in the list below are sorted by architecture from older to newer. To properly select a GPU you need to understand your memory requirements. Not enough memory won’t allow to fit a model and too much will lead to inefficient use of GPU and money. Newer GPUs have more and faster CUDA cores, higher memory bandwidth and offer faster computation involving smaller precisions such as INT8 or FP8. All GPUs in the list support FP64 also known as double precision, but it is used for scientific computations whereas AI and Deep Learning models rely on FP32 or single precision and smaller ones.

NVIDIA Superchips
In 2023 in addition to its GPUs NVIDIA introduced a high performance Grace CPU. The CPU is used as a part of NVIDIA Superchips and offers higher performance per Watt in comparison with conventional x86–64 CPUs. The Superchips fall into two categories, one that contains a pair of Grace CPUs and the ones that include a Grace CPU and one or two NVIDIA datacenter GPUs. The first Superchips were introduced along with Hopper GPU architecture and consist of one H100 or H200 GPUs and one Grace CPU. Blackwell architecture introduces Superchips consisting of one Grace CPU and two GPUs with Blackwell architecture such as B100.
NVIDIA Grace Superchip consists of two NVIDIA Grace CPUs connected via NVLink. In total the Superchip boasts 144 Arm Neoverse V2 cores and up to 960 GB of LPDDR5X with the bandwidth that can reach 1 TB/s and draws 500 W of power. Grace Superchip is intended for High Performance Computing (HPC) Applications such as fluid dynamics, numerical weather prediction, and DNA sequencing.
NVIDIA Grace Hopper GH200 Superchip features up to 480 GB of LPDDR5X CPU memory and up to 72 Arm Neoverse V2 cores. The Superchip variant with HBM3 has 96 GB of memory with the bandwidth of 4 TB/s. Another variant with HBM3e has 144 GB of GPU memory with 4.9 GB/s bandwidth. The CPU and GPU are connected via NVLink inside the Superchip.
The idea behind a CPU-GPU superchip such as Grace Hopper is to remove communication, computation, and memory bottlenecks. For example LLM inference requires a lot of memory to store model’s weights and biases along with intermediate results and data batches. One approach to solve memory requirements is to use multiple GPUs. Another approach is to offload some weights to the CPU memory. As the CPU and GPU in the Grace Hopper are connected via NVLink, not PCIe interface, a possible bottleneck to layer data offloading is removed.
