Dell PowerEdge XE9680 vs QCT QuantaGrid D75F-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 D75F-7U
QCT's 7U Hopper machine, with two fifth or fourth generation Intel Xeon Scalable processors and eight NVIDIA HGX H200 GPUs linked at 900 GB/s over NVLink. Storage is eighteen small-form-factor all-NVMe bays for GPU-Direct Storage plus a boot drive, and two NVIDIA BlueField-3 DPUs offload networking. QCT gives 1.1 TB of aggregate high-bandwidth memory. It also quotes over 32 petaflops of FP8, which is not shown here: QCT does not say whether that is dense or sparse, it is close to double the dense figure NVIDIA published for this baseboard, and NVIDIA no longer lists the H200 on its HGX page, so there is no way to settle which column it belongs in without guessing. Power is four-plus-two 4,000 W Titanium supplies, which is capacity rather than draw.
