Today we got our hands on the ASRock X670E Pro RS, which is the bigger brother of the ASRock B650 Pro RS we reviewed earlier this year that we quite liked.  The ASRock X670E Pro RS is available in the upper $200 range online currently, so it is quite an affordable X670E-based motherboard.  We are going to put this board to the test and see if it is worth the premium over its little brother. The ASRock X670E Pro RS is based on AMD’s X670E chipset, the current top-of-the-line chipset from AMD.
