ASUS ESC NB8-E11 vs Lenovo ThinkSystem SR780a V3 (HGX B200)
Both are built on the NVIDIA HGX B200 8-GPU baseboard, so their accelerator performance is identical rather than merely similar. The choice between them is chassis, cooling, expansion and supplier, not FLOPS.

ASUS ESC NB8-E11
A 10U eight-GPU server built on the NVIDIA Blackwell HGX B200 baseboard, with dual 5th generation Intel Xeon Scalable processors at 350 W and NVLink giving 1,800 GB/s directly between GPUs, twice the bandwidth of the Hopper-generation ESC N8-E11. It uses a dedicated one-GPU-to-one-NIC topology supporting up to eight NICs, and offers up to 11 PCIe slots, 32 DIMM slots, 10 NVMe bays and dual 10Gb LAN, with 5+1 80 PLUS Titanium supplies. Unlike many B200 platforms it is air-cooled, using dedicated CPU and GPU airflow tunnels, which is what accounts for the 10U height. ASUS publishes no FLOPS figure of its own, so the compute shown is NVIDIA's for the HGX B200 baseboard, including the sparse figures NVIDIA publishes for Blackwell. ASUS's detailed specification tab does not render server-side, so chassis dimensions, weight and power supply wattages could not be read and are deliberately absent.
Vendor product pageLenovo ThinkSystem SR780a V3 (HGX B200)
The Blackwell configuration of Lenovo's SR780a V3, ordered under base feature code C695 and built on a ThinkSystem NVIDIA HGX B200 180GB eight-GPU liquid-cooled board rated at 1000 W per accelerator, against 700 W for the Hopper board in the same chassis. That is the case for the design: sixth generation Lenovo Neptune water cooling on four loops takes CPUs, GPUs and NVLink switches, removing up to 75 percent of the heat in warm water, and eight kilowatt-class accelerators still fit in 5U where the air-cooled machines in this catalogue need 8U or 10U. The chassis is 447 by 219 by 942 mm at up to 92 kg, hosted by two fifth-generation Intel Xeon Scalable processors at 56 cores and 350 W, with eight hot-swap supplies in N+N redundancy. Lenovo publishes no system power draw, no accelerator memory total and no system-level throughput; the linked HGX B200 entry carries NVIDIA's figures.
