ASUS Pro WS WRX90E-SAGE SE vs ASRock TRX50 WS Motherboard

Buy the ASUS Pro WS WRX90E-SAGE SE if you need maximum memory bandwidth and slot count: 8 DDR5 channels and 7 PCIe 5.0 x16 slots suit multi-GPU compute, large datasets and heavy virtualization. Buy the ASRock TRX50 WS if you want a simpler, cheaper-class workstation board with 4 channels, 10G plus 2.5G Ethernet and Wi-Fi 6E built in. The ASUS is the more expandable board; the ASRock is the easier one to live with. Owner reports on the ASUS include a board that would not power on and a BIOS flashback that failed, so test it early.

• Choose the ASUS Pro WS WRX90E-SAGE SE if you run Threadripper PRO with 8-channel memory and need seven full PCIe 5.0 x16 slots for GPUs, capture cards or NVMe arrays.
• Choose the ASRock TRX50 WS if you want Threadripper PRO power in a 4-channel board with onboard Wi-Fi 6E and dual Ethernet, and you do not need eight memory channels.
