Our Verdict on Each
A capable HEDT chip with strong multi-threaded performance and ample I/O, but power-hungry by modern standards and best pursued used or for legacy X299 builds.
Best for: Upgrading or completing an existing LGA2066/X299 build at a low used price
Read the full reviewA powerful HEDT CPU with excellent multi-threaded throughput and massive I/O, but high power draw and an aging platform make it best suited for used workstation builds today.
Best for: Used workstation or HEDT build where 44 PCIe lanes and 16 cores are critical and platform cost is low.
