Core i5-6402P Details

For users seeking a capable mainstream desktop processor with integrated graphics and efficient power consumption, the Intel Core i5-6402P offers a balanced solution built on the Skylake architecture. Released in 2016, this CPU is now over seven years old, placing it in the category of older, mature hardware. While no longer competitive with modern processors, it remains a reliable option for basic productivity, media consumption, and light multitasking in systems where discrete graphics are not required.

The Core i5-6402P is a quad-core, four-thread processor based on Intel’s 14 nm Skylake microarchitecture. It features a base clock of 2.8 GHz and can boost to 3.4 GHz on a single core, providing a modest performance uplift under load. It is built on a 14 nm CMOS process and operates at a 65 W TDP, making it suitable for standard desktop cooling solutions. The processor uses the LGA-1151 socket and supports both DDR3L-1600 and DDR4-2133 memory, with a maximum capacity of 64 GiB and a peak memory bandwidth of 31.79 GiB/s.

Cache-wise, the i5-6402P includes 0.25 MiB of L1 cache (0.125 MiB for both L1i and L1d), 1 MiB of L2 cache, and a shared 6 MiB L3 cache. It supports a range of modern instruction sets, including SSE, AVX, AVX2, AES-NI, and Intel’s Turbo Boost 2.0 technology, which allows dynamic frequency scaling based on workload and thermal conditions. The processor also supports virtualization technologies such as Intel VT-x and VT-d, making it suitable for light virtualization tasks.

Integrated into the CPU is Intel’s HD Graphics 510, featuring 12 execution units and a maximum frequency of 950 MHz. This GPU supports up to three displays and can decode common video formats, making it suitable for office applications, web browsing, and standard-definition media playback. While it lacks the performance of dedicated graphics cards, it provides a functional graphics solution without requiring additional hardware.

In benchmark testing, the Core i5-6402P achieves an overall score of 5144, ranking it #756 of 2060 processors. Its single-core score of 5356 places it at #685, indicating relatively strong per-core performance for its era. However, its multicore score of 4825, ranking #815, reflects limitations in parallel processing due to its four-core design and lack of modern optimizations. It outperforms some older dual-core and lower-tier processors but trails significantly behind current-generation CPUs, especially in multi-threaded workloads.

As of March 2026, the Core i5-6402P is best suited for entry-level desktop systems, small office environments, or as a replacement in older machines where upgrading to a modern platform is not feasible. While its age and limited performance make it unsuitable for gaming, content creation, or high-performance computing, it remains a dependable choice for general computing tasks in systems where cost and power efficiency are priorities.
