Is this the new AMD Threadripper motherboard you need? Read our indepth analysis. When Gigabyte unveiled the X399 Aorus Xtreme motherboard we could see they were taking AMD 2nd Gen. Threadripper seriously.Gigabyte X399 Aorus Xtreme Review (w/ AMD 2990WX)
The new Threadripper WX models increased TDP from 180W to 250W so while it would be quite possible to install a 32-core 2990WX in a motherboard such as Gigabyte X399 Aorus Gaming 7 you wouldn’t be surprised if it struggled to supply the CPU with enough power. Gigabyte was clearly thinking along the same lines and has updated the VRMs from the 8+2 configuration used in the Gaming 7 to a 10+3 arrangement in the Xtreme. In addition to this hardware Gigabyte has put a significant emphasis on keeping the components nice and cool.
