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.
