Intel Core i7-9700

Our Verdict on Each

A highly popular, cost-effective 6-core processor that delivers excellent value for mainstream users, though lacking Hyper-Threading limits its heavy multitasking ceiling.

Best for: Upgrading an older LGA 1151 system on a budget, or building an office/HTPC machine.

Read the full review

A solid 8-core CPU that offers good productivity and gaming performance at a lower 65W TDP, though it lacks Hyper-Threading and overclocking capabilities.

Best for: The Intel Core i7-9700 is a solid processor for the used market, particularly for budget gaming or productivity builds. If you can find it at a good price, its 8 cores provide ample performance for modern gaming and multitasking. The inclusion of a 65W TDP means it runs cool and can be paired with cheaper motherboards and coolers, saving you money on the overall build. It is highly recommended for users upgrading an existing 8th or 9th Gen Intel system who don't care about overclocking. However, avoid this CPU if you need maximum multi-threaded performance, as the lack of Hyper-Threading holds it back in rendering tasks. For new builds, modern CPUs offer better price-to-performance ratios. Ultimately, the i7-9700 is best suited for practical builders who want reliable, efficient performance without paying for unnecessary enthusiast features.
