ASRock TRX50 WS Motherboard vs ASRock W790 WS R2.0

Both are ASRock workstation boards for people who need many PCIe lanes and lots of memory. The TRX50 WS is the pick for a new AMD Threadripper 7000 build: sTR5 socket, four DDR5 slots up to 1 TB, and Threadripper PRO support. The W790 WS R2.0 is the pick if you already own or want an Intel Xeon W chip: eight DIMM slots, up to 2 TB, and four PCIe Gen5 x16 slots. Build quality is comparable, both are EATX-class boards with 10Gb LAN, and owners of both report stable operation under sustained workstation loads.

• Choose the ASRock TRX50 WS if you are building around an AMD Ryzen Threadripper 7000 or Threadripper PRO 7000 CPU and want a current-generation platform.
• Choose the ASRock W790 WS R2.0 if you need Intel Xeon W, eight memory slots, or the maximum memory ceiling for a large-memory workstation.
