Nvidia used this week's GPU Technology Conference in San Jose to reveal the most powerful GPU box that its R&D labs have cooked up.

The RTX Blade Server uses blade configuration to squeeze up to 40 Turing GPUs into an 8U enclosure, for as many as 184,320 CUDA cores. Multiple enclosures can be combined into a "pod", with up to 1,280 GPUs working as a single system.
