Our Verdict on Each
A solid HEDT processor for users who need quad-channel memory and 44 PCIe lanes, but outclassed in efficiency and single-thread performance by newer mainstream and HEDT parts.
Best for: Used or discounted X299 workstation build where quad-channel memory and 44 PCIe lanes are critical and platform cost is low.
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.
