Our Verdict on Each

A highly cost-effective 6-core CPU that delivers excellent value for 1080p gaming and general computing, despite its locked multiplier and older 14nm process.

Best for: The Intel Core i5-10400 is highly recommended for users building a budget to mid-range 1080p gaming PC or a general-purpose home/office computer. Its 6-core, 12-thread configuration provides excellent longevity for everyday tasks, light content creation, and modern gaming when paired with a mid-range GPU like an RTX 3060 or RX 6600. The inclusion of UHD 630 graphics means the system is functional even if a discrete GPU fails or is delayed in purchase. Because it is a locked processor, there is no need to invest in expensive Z-series motherboards or high-end cooling; a simple B460 board and the stock cooler are sufficient. This makes it an ideal choice for budget-conscious buyers who prioritize stability, reliability, and maximum value over enthusiast-level tweaking or extreme frame rates.

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.
