QCT 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.

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.

Typical Use Cases
The QCT QuantaGrid D75F-7U runs 8× H200 GPUs over One NVIDIA HGX H200 baseboard connecting the eight GPUs at 900 GB/s over NVLink, which QCT notes is seven times the bandwidth of PCIe Gen 5; two BlueField-3 DPUs handle networking, delivering 15,832 TFLOPS FP8 dense.
