Verdict

The Intel Core i5-6402P is a 6th Generation Skylake quad-core desktop processor featuring a base clock speed of 2.80 GHz and a max turbo frequency of 3.40 GHz. Built on a 14nm lithography with a 65W TDP, it includes a 6 MB Smart Cache and supports up to 64 GB of DDR4-2133 or DDR3L-1600 memory. Main pros include its solid quad-core performance for budget gaming and productivity, low power consumption, and compatibility with the LGA 1151 socket. Primary cons are its weak integrated Intel HD Graphics 510, lack of hyper-threading (4 cores/4 threads), and its status as a discontinued legacy component that lacks official support for modern operating systems like Windows 11.

What customers like about Intel Core i5 6402P?

  • Superior pure processor performance compared to the i5-6400, often cited as ~10-15% faster under heavy load.
  • Excellent value for budget-conscious gamers when paired with a discrete graphics card.
  • Efficient thermal performance, with users reporting it stays relatively cool (around 60°C) even under full load.
  • Higher base and turbo clock speeds than similar models in its price range during its initial release.
  • Remains capable of handling many older titles at stable frame rates on custom settings.

What customers dislike about Intel Core i5 6402P?

  • Weak integrated graphics (Intel HD Graphics 510), making it unsuitable for gaming without a dedicated GPU.
  • Significant bottlenecking in modern, CPU-intensive titles such as Assassin's Creed Origins.
  • Limited multitasking capabilities due to having only 4 cores and 4 threads without hyper-threading.
  • Noticeable performance lag when running more modern operating systems like Windows 11.
  • Inconsistent performance when attempting to maintain max turbo speeds across all four cores simultaneously.
