Our Verdict on Each
A fast 10-core Comet Lake CPU that still performs well in modern games and multi-threaded workloads, but its high real-world power consumption, heat, and locked multiplier make it hard to recommend over newer or unlocked alternatives in 2026.
Best for: Used or discounted LGA1200 builds where you already have a strong GPU and a capable Z490/Z590 board and want maximum multi-threaded performance for the price.
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.
