Our Verdict on Each
A niche, high-clock quad-core for X299 that delivers strong single-threaded performance but lacks the PCIe and memory bandwidth of Skylake-X siblings, making sense only at low prices for specific reuse scenarios.
Best for: Reusing an existing LGA2066 board for gaming or general tasks when the CPU is acquired at very low cost.
Read the full reviewA powerful 10-core Comet Lake CPU that still delivers excellent gaming and creator performance, but its high power draw and lack of iGPU make it a tougher sell versus newer alternatives.
Best for: Used or discounted builds where high core count and high clocks are more important than efficiency or platform longevity.
