This article covers Intel Comet Lake Core i5-10400 2.90Ghz 12MB CPU.

Overview

The Intel Core i5-10400 is a desktop processor from the 10th generation Comet Lake family, launched in April 2020. It features 6 cores and 12 threads with a base clock of 2.9 GHz and a maximum turbo boost of 4.3 GHz. Built on the 14nm process, it has a 65W TDP, making it a power-efficient choice for budget and mid-range builds. The CPU uses the LGA1200 socket and works with Intel 400-series chipsets like B460, H410, and Z490. This processor is ideally suited for entry-level to mid-range gaming PCs, office productivity, and light creative work. It includes Intel UHD Graphics 630, so you can get display output without a dedicated graphics card. However, for modern AAA gaming or heavy video editing, pairing it with a mid-range GPU is necessary. The i5-10400 remains a solid value option for builders on a tight budget, especially when upgrading an older LGA1200 system.

Compatibility Guide

The Core i5-10400 requires an LGA1200 socket motherboard. It is fully compatible with Intel 400-series chipsets (B460, H410, Z490, Q470) out of the box. It also works with 500-series chipsets (B560, H510, Z590) after a BIOS update. Memory support is dual-channel DDR4-2666, with a maximum capacity of 128GB. The CPU supports PCIe 3.0, so you won't get the full speed of PCIe 4.0 SSDs or GPUs, but for most mid-range builds, this is not a bottleneck. For power, if you rely solely on the integrated graphics, a 300W PSU is sufficient. If you add a mid-range GPU like an RTX 3060, a 500W PSU is recommended. The CPU comes with a stock cooler, which is adequate for standard use but may be noisy under load. If you prioritize silence, consider an aftermarket LGA1200 cooler.

Product Info

The Intel Core i5-10400 was released in April 2020 as a mid-range offering in the Comet Lake lineup. It uses a 14nm process, has 6 cores/12 threads, 12MB of L3 cache, and a 65W TDP. The integrated GPU is Intel UHD Graphics 630 with a base frequency of 350 MHz and a maximum of 1.10 GHz. The original retail price was around $180, and today it can be found for about $130–150. Intel provides a standard 3-year warranty. In the market, the i5-10400 sits in the entry-to-mid tier. At launch, it competed with AMD's Ryzen 5 3600, offering slightly lower single-thread performance but better platform stability and a wider range of affordable motherboards. While newer platforms like LGA1700 have since taken over, the i5-10400 remains a viable choice for budget builds, especially when upgrading an existing LGA1200 system.

Best Use Cases

Budget 1080p Gaming Pair this CPU with a GPU like GeForce RTX 3050 or GTX 1660 Super for 1080p gaming at 60+ fps in most titles. The low cost of the CPU and compatible B460 motherboards makes it an excellent choice for first-time builders. However, for competitive shooters aiming for 144+ fps, a newer CPU would be better. Office and Home PC With integrated graphics, the i5-10400 handles office applications, web browsing, and video streaming effortlessly. It's also great for a quiet home server or HTPC. The stock cooler is adequate, but an aftermarket cooler can reduce noise further. * Secondary PC or NAS Its low power draw and stable performance make it suitable for a file server, home lab, or backup machine. Just be aware that PCIe 3.0 limits the speed of NVMe SSDs, though for NAS use, this is rarely an issue.

Things to Consider

The i5-10400 is now several generations old, and its single-thread performance and IPC are significantly behind newer Intel 12th/13th gen and AMD Ryzen 5000/7000 CPUs. If you want the best possible gaming or creative performance, you should invest in a newer platform. The CPU also lacks PCIe 4.0 support, so you won't benefit from the fastest SSDs or GPUs. Memory is limited to DDR4-2666 officially, meaning faster RAM won't give much improvement unless you use a B560 motherboard with overclocking support. Another consideration: the LGA1200 platform is dead-end, with no CPU upgrade path beyond Comet Lake. If you plan to upgrade in the future, you'll need a new motherboard. For a budget build that you don't plan to upgrade heavily, the i5-10400 is still a good value, but if you have any aspirations for high-end gaming or content creation, look at newer options. ## FAQ
Q: Can the Core i5-10400 run Windows 11? A: Yes, it supports Windows 11. You need to enable TPM 2.0 and Secure Boot in the BIOS. Most B460 and Z490 motherboards have this option. Q: Which motherboards work without a BIOS update? A: Intel 400-series chipsets (B460, H410, Z490) are compatible out of the box. For 500-series chipsets, you may need a BIOS update. Always check the motherboard's CPU support list before purchase. Q: Is the i5-10400 better than the Ryzen 5 3600? A: The Ryzen 5 3600 has slightly better single-thread and multi-thread performance, but the i5-10400 is often cheaper when you factor in motherboard costs. The i5 also has integrated graphics, w
