Our Verdict on Each

One of the best value desktop processors of its generation, offering 95% of the i7-8700K's performance at a lower price and power draw.

Best for: Upgrading an existing LGA 1151 system for high-refresh gaming.

Read the full review

A legendary gaming CPU that introduced 8 cores to the i7 lineup. Its high clocks and unlocked multiplier make it great for enthusiasts, though it lacks Hyper-Threading.

Best for: For PC builders considering the Core i7-9700K today, it is only recommended if purchased used at a significant discount. It remains an excellent gaming CPU, capable of handling modern titles without bottlenecking mid-range GPUs. The unlocked multiplier allows for easy overclocking, extending its lifespan. However, the lack of Hyper-Threading limits its potential in heavily multi-threaded productivity tasks like video editing or 3D rendering compared to modern CPUs. Avoid this processor if you are building a new system from scratch, as the LGA 1151 socket is dead, offering no upgrade path. If you already own a Z390 motherboard and are upgrading from a lower-tier 8th or 9th Gen CPU, the 9700K is a worthwhile investment. For everyone else, an AMD Ryzen 5 5600X or Intel Core i5-12400F offers better value, modern architecture, and an upgrade path.
