compatibility and stability The processor works very stably with most motherboards on the Intel 100 series chipset. I had no issues with BIOS settings or drivers. This ensures peace of mind and reliability in long-term operation. High performance for the mid-range class. Low heat emission. Energy efficiency. Compatibility with many motherboards. Works well for office tasks and light gaming. -  Oleg: use Intel i5-6500 BOX more than year |
A monster processor, I’ve been rooting for it since 2016. Really happy with my choice. To finish it cold, a boxed cooler is enough, which allows you to finish it quietly. Energy-efficient (does little for its productivity). Productivity is guaranteed with self-regulation of frequencies and cores. Navigation 2023 has a current option.

Middle class
Intel Core i5-6400 is the youngest and, accordingly, the most affordable model of the Skylake generation Core i5 processor series. The i5-6400 at 2.7 GHz costs an average of $190, while the i5-6500 at 3.3 GHz costs $230. For this amount, in addition to the processor itself, you get a cooler, albeit not silent, but quite sufficient to remove 65 W of heat.
Four means four
All desktop Core i5 models are true quad-cores, while the younger Core i3s have only two physical cores and two more virtual cores. Therefore, the Core i5 is about one and a half times faster than the Core i3. Most of all, the difference is felt in professional applications and processor-intensive games such as Battlefield 4, Arma 3, Assassin's Creed Syndicate, etc.
Auto acceleration in addition
The nominal frequency of the Core i5-6400 is relatively low - 2.7 GHz, but the technology of guaranteed automatic overclocking Turbo Boost comes to the rescue. So, with a load on all cores, the processor accelerates to 3.1 GHz, and with a load of only one core - up to 3.3 GHz. As a result, we can recommend the i5-6400 for building an advanced gaming PC with a Radeon RX 480, GeForce GTX 1060 and more powerful graphics card.
