The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles everyday productivity and multitasking without issues.
12 threads handle moderate workloads well, but slower than modern 8-core chips.
Gaming
Capable of smooth 1080p gaming when paired with a mid-range GPU.
Still holds up well for 1080p gaming, though newer CPUs pull ahead in CPU-bound titles.
Virtualization
Suitable for basic virtualization needs with 12 threads.
Adequate for basic VMs, but limited by 6 cores.
Efficiency
Power consumption is reasonable, though the 14nm process is less efficient than newer nodes.
14nm process is power-hungry under load compared to current architectures.

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.
