Notes
Unveiled at GTC March 2024. 10 RU air-cooled chassis with 2x Intel Xeon Platinum 8570 (112 cores) and 2 TB system memory, configurable to 4 TB. Networking is 4x OSFP serving 8x single-port ConnectX-7 plus 2x dual-port QSFP112 BlueField-3 DPUs, each up to 400 Gb/s. Same eight B200 SXM parts as HGX B200; the 14.3 kW figure is the whole system, against 10.2 kW for the bare baseboard.
