Motherboard makers are starting to roll out BIOS updates for AMD’s Raven Ridge APUs, which are based on AMD's Zen architecture, combining up to 4 Zen-based CPU cores with integrated Vega graphics. ASUS is one of the first out the door with BIOS updates for models ranging from the Prime X370-PRO to ROG Strix X370-F Gaming. AMD deserves kudos for not forcing users to upgrade their motherboards. Intel has taken the opposite approach with its Coffee Lake release, as even though Coffee Lake uses the same LGA 1151 socket as Kaby Lake, they require an upgrade to a Z370 chipset motherboard. To make matters even more frustrating, Intel has instructed motherboard makers not to support Kaby Lake CPUs in Z370 motherboards.
