ASROCK X399 Professional Gaming and X399 Taichi
Looks like AMD and Intel are ready to compete head to head with high-performance desktop platforms at Computex.
ASRock has just showcased its X399 motherboards: Professional Gaming and Taichi. Both ship with four PCI-Express slots and eight memory DIMMs. It also does appear that both X399 Professional Gaming and X399 Taichi also have WiFi antennas and two ethernet connectors. Unlike X399 AORUS Gaming 7 the duo from ASRock has only 8-pin power connector for Ryzen Threadripper.
