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.

An efficient and cool-running chip for its time, but severely outdated by modern dual-core standards.

Best for: If you are considering the Core i5-4570T today, it should only be for upgrading an existing LGA 1150 system where your current chip is failing, or for building a very basic retro or office PC using salvaged parts. It holds no value for new purchases due to its age and lack of modern feature support. If found cheaply, it can serve as a capable home server or HTPC processor, handling media streaming and basic network tasks adequately. However, its dual-core limitation will be a bottleneck for modern web browsing with heavy scripts. Do not spend more than a few dollars on this processor. Anyone building a new system should look toward modern 12th or 13th Gen Intel alternatives, or AMD's Ryzen series, which offer vastly superior efficiency and performance.
