Gigabyte MC62-G40 vs ASRock WRX90 WS EVO

These are workstation boards from two different generations, and the gap is large. The ASRock WRX90 WS EVO is the newer platform: sTR5 socket, Threadripper PRO 7000WX support, PCIe 5.0 across seven x16 slots, DDR5 at up to 7600 MHz and a built-in BMC with dedicated IPMI LAN. The Gigabyte MC62-G40 is the older WRX80 board: sWRX8 socket, Threadripper PRO 5000WX up to 280W, PCIe 4.0, DDR4 up to 3200 MT/s and no management controller. Owners of WRX80 boards praise the platform's stability and the eight-channel memory, but it is a dead-end socket. Buy the ASRock unless you already own a 5000WX CPU or need a compact CEB board.

• Choose the Gigabyte MC62-G40 if you already have a Threadripper PRO 5000WX chip, need the smaller CEB footprint, or want a proven DDR4 platform with dual 10GbE and no management overhead.
• Choose the ASRock WRX90 WS EVO if you are building new, want PCIe 5.0 and DDR5 headroom, or need out-of-band IPMI management for a rack or remote lab.
