QCT QuantaGrid S74G-2U
QCT's Grace Hopper machine, and its entry in the first generation of NVIDIA's MGX modular architecture, which QCT says it partnered with NVIDIA to introduce. A single GH200 Superchip pairs 72 Arm Neoverse cores with a Hopper GPU over NVLink-C2C, giving one coherent memory pool across CPU and GPU rather than a host and a device that copy between them. QCT lists up to 480 GB of embedded LPDDR5X alongside 96 GB of HBM3 GPU memory, four E1.S NVMe drives by default, and three full-height full-length dual-width PCIe 5.0 x16 slots in a 2U chassis 900 mm deep. The memory figure here counts the HBM only, since the LPDDR5X is the Grace side of the pair. Power is one-plus-one 2,000 W Titanium supplies, which is capacity rather than draw, and QCT publishes no throughput figure.

Frequently asked questions
How much does the QuantaGrid S74G-2U cost?
QCT sells the QuantaGrid S74G-2U on quote through OEMs and resellers, and nobody rents a whole one by the hour. Renting its 1 GH200 accelerators separately at the cheapest live rate Flopper tracks, $2.75 per GPU-hour across 2 providers, comes to about $2.75 an hour for the equivalent capacity.

How much power does the QuantaGrid S74G-2U require?
QCT has not published a power figure for the QuantaGrid S74G-2U, and Flopper does not derive one from the accelerator count because the rest of the system draws power too.
How many GPUs are in the QuantaGrid S74G-2U?
1. The QuantaGrid S74G-2U carries 1 NVIDIA GH200 96GB HBM3 accelerators in a rack form factor, and every throughput figure on this page is the total across them. GH200 specifications →
