ASRock introduced the W790 WS R2.0 motherboard for workstations powered by 4th Gen Intel Xeon W-3400 and W-2400 series processors in the Socket LGA4677 package.
Although its model name suggests that it is a revision of the W790 WS, the new W790 WS R2.0 appears to be a lite version of the original, which removes several I/O features.
While the CPU VRM appears unchanged, the VRM heatsinks used on the R2.0 are of a simpler design. The design effort behind both these changes appears to be to make the board friendly to certain kinds of rackmount chassis.
