The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles everyday productivity and multitasking without issues.
The high boost clock makes everyday office tasks feel extremely responsive, though DDR4-2666 limits heavy data crunching.
Gaming
Capable of smooth 1080p gaming when paired with a mid-range GPU.
Slightly better single-core speed than the 10320, but still requires a discrete GPU and is bottlenecked by PCIe 3.0.
Virtualization
Suitable for basic virtualization needs with 12 threads.
8 threads are usable for a light VM setup, but the 65W TDP limits sustained virtualization performance.
Efficiency
Power consumption is reasonable, though the 14nm process is less efficient than newer nodes.
Average efficiency for 14nm. AMD's competing chips at this price point draw less power for similar or better multi-core output.

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.
Read the full reviewA niche OEM stopgap that offered slight clock improvements and newer chipset support, but it was quickly outclassed by 11th-gen alternatives.
Best for: Buying an Intel Core i3-10325 for a custom PC build in today's market makes very little sense. If you are purchasing a pre-built desktop or a barebones system that already includes this processor, it remains a solid performer for office work, homeschooling, and general home use. The 4.7 GHz boost clock ensures that snappy day-to-day responsiveness is present. However, if you are sourcing parts individually, you should absolutely opt for the 11th-generation Core i3-12100 or the i5-11400. Those processors offer significantly better IPC, DDR4-3200 memory support, and PCIe 4.0, often at similar or lower price points. The i3-10325's DDR4-2666 memory limitation is its biggest liability, holding back both CPU and integrated graphics performance. Only consider this chip if you are upgrading a locked OEM system that specifically requires a 400 or 500-series compatible CPU with these exact power characteristics.
