Dell PowerEdge XE9680 vs QCT QuantaGrid D74F-7U
Both are built on the NVIDIA HGX H200 baseboard, so their accelerator performance is identical rather than merely similar. The choice between them is chassis, cooling, expansion and supplier, not FLOPS.

Dell PowerEdge XE9680
6U rack server built on the NVIDIA HGX H200 baseboard. Two Intel Xeon Scalable sockets (4th or 5th Gen, up to 64 cores each), 32 DDR5 DIMM slots to a 4 TB maximum, and 2800W Titanium redundant hot-swap power supplies. The same chassis is also orderable with 8x H100 80GB, 8x AMD Instinct MI300X 192GB or 8x Intel Gaudi3 128GB; Dell does not list a B200 option. System-level power draw is not published, so only the baseboard figure on the HGX H200 reference page is authoritative.
Vendor product pageQCT 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.
