Core i5-10400 Details

Ranked #524 in single-core performance with a score of 5539, the Intel Core i5-10400 stands out for its strong per-core efficiency, despite being a 2020-era processor. While its 6-core, 12-thread configuration may not seem impressive by today’s standards, the chip holds its own in single-threaded workloads, placing it ahead of several high-end mobile and desktop CPUs like the Core i7-9850HE and Core i7-6800K. This performance is driven by a base clock of 2.9 GHz and a turbo frequency of 4.4 GHz, leveraging Intel’s Comet Lake architecture on a mature 14 nm process node. The 65 W TDP ensures low power consumption and manageable heat output, making it a reliable option for mainstream desktop builds.

The Core i5-10400 features a robust cache hierarchy, with 0.061 MiB of L1, 0.244 MiB of L2, and a generous 11.444 MiB of L3 cache, which aids in reducing memory latency and improving responsiveness. It supports DDR4 memory up to 2666 MT/s via a dual-channel memory bus, delivering a memory bandwidth of 42.7 GB/s—adequate for general computing and light content creation. The processor uses the LGA1159 socket, which is compatible with a wide range of motherboards from the same generation, offering good upgrade flexibility for users.

On the integrated graphics front, the UHD Graphics 630 provides basic visual performance, suitable for office tasks, HD video playback, and casual gaming at lower settings. While not a replacement for a discrete GPU, it enables a functional zero-GPU setup for users on a budget. The chip supports a range of instruction sets, including AVX, AVX2, and AES-NI, making it capable of handling encryption and media processing efficiently. It also supports hardware virtualization technologies such as Intel VT-x and VT-d, which enhance virtual machine performance.

In multicore benchmarks, the Core i5-10400 achieves a score of 5055, placing it at #600 overall. This reflects its strong multi-threaded performance, particularly in workloads that can leverage its 12 threads effectively. It outperforms several older and mid-range processors, including the Xeon E-2224 and Core i7-8706G, though it trails behind more modern offerings like the Ryzen 3 4100 and Core i7-1185G7. Its overall score of 5345 positions it just ahead of the Core i7-9850HE and Xeon E5-1630 v4, indicating a balanced performance profile.

As of March 2026, the Core i5-10400 remains a practical choice for budget-conscious users, light content creators, and those building systems where integrated graphics suffice. While newer CPUs dominate the high-end market, this processor still holds value in its segment due to its efficiency, strong single-core performance, and affordability. It is best suited for everyday computing, office applications, and entry-level productivity tasks, though power users may find its performance limiting in heavily threaded scenarios.
