QCT QuantaGrid D74F-7U
The OCP-slot variant of QCT's 7U Hopper machine, carrying the same eight NVIDIA HGX H200 GPUs at 900 GB/s over NVLink and the same 1.1 TB of aggregate high-bandwidth memory as the D75F-7U. The differences are in I/O and packaging: one BlueField-3 DPU rather than two, ten OCP 3.0 TSFF PCIe Gen 5 slots, a shorter 886 mm chassis, and three-plus-three 4,000 W Titanium supplies. QCT quotes the same over 32 petaflops of FP8 figure, which is not shown here for the same reason as on the D75F: the basis is unstated and cannot be settled. Power figures are supply capacity, not draw.

Where a vendor states a basis, the figure shown is the dense one, and any figure it publishes is listed separately. Vendors commonly headline the sparse number instead: for NVIDIA's 2:4 structured sparsity that is exactly twice the dense figure, though other vendors' sparse modes do not all follow that ratio.

Frequently asked questions
How much does the QuantaGrid D74F-7U cost?
QCT sells the QuantaGrid D74F-7U on quote through OEMs and resellers, and nobody rents a whole one by the hour. Renting its 8 H200 accelerators separately at the cheapest live rate Flopper tracks, $2.09 per GPU-hour across 21 providers, comes to about $16.72 an hour for the equivalent capacity. H200 rental prices →
How much power does the QuantaGrid D74F-7U require?
QCT has not published a power figure for the QuantaGrid D74F-7U, 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 D74F-7U?
8. The QuantaGrid D74F-7U carries 8 NVIDIA H200 SXM 141GB accelerators in a rack form factor, and every throughput figure on this page is the total across them. H200 specifications →
