MikroTik’s CRS804-4DDQ-hRM provides four 400-gigabit Ethernet ports for desktop and local AI clusters.

The MikroTik CRS804-4DDQ-hRM is a four-port 400-gigabit Ethernet switch. ServeTheHome evaluated it as a desktop-class networking device that had been used for local AI clusters.

The product addresses network connectivity between systems rather than supplying compute itself: it is a switch, not a GPU, accelerator, server, rack, or cluster. Its four 400GbE ports provide the physical high-speed links described in the review.

The supplied source characterized the device as a comparatively inexpensive desktop 400GbE switch. It did not provide a price, aggregate switching capacity, power draw, port breakout configuration, or measured local-cluster benchmark in the supplied description.
