BX80684I59400

Debuted in 2019, the representative of the 9th generation of Intel processors is part of the Coffee Lake Refresh line and is positioned by the manufacturer as an affordable solution for creating an entry-level gaming computer. The model provides 6 cores with a clock speed of 2.9 GHz each. The proprietary development of Turbo Boost allows, under loads, to automatically increase the standard figure to 4.1 GHz for one of the cores.

The Intel i5-9400 BOX processor differs from the i5-9400F counterpart in the presence of an integrated video chip. In its role, the UHD Graphics 630 core is used, which supports 4K video and allows you to run popular multiplayer games such as Dota 2 or CS: GO at minimum settings. The processor is compatible with motherboards with an LGA 1151 v2 socket and is able to work correctly with 128 GB of DDR4 2666 MHz RAM. The model is characterized by low heat dissipation (up to 65 W) and is able to maintain performance when heated up to 100 °C.

Time for improvements

The Core i5-9400 is perhaps the most interesting processor in the Coffee Lake Refresh family. And it's funny, because his younger brother i5-8400 looked like the most interesting chip in the line of the last generation. The i5-9400 has the same 6 physical cores without multithreading, but the frequencies have slightly increased: in normal mode we now have 2.8 GHz, and in boost 4.1 GHz. In fact, the power has grown to the level of the Core i5-8500.

The price decides

So what's so interesting about it? As in the case of the younger new generation Core i3, Intel decided to shock the market with low prices, in fact, killing most of the previous generation processors. Why buy an i5-8400 for almost $200 when a more powerful new one costs $160? Here we don't know. Plus, Coffee Lake Refresh has a strange pricing situation: the same version of the processor with integrated graphics and without it can make a significant difference in price. The i5-9400 with and without graphics has the same price tag, so the UHD Graphics 630 can be seen as a small bonus that allows you to watch 4K videos or run CS:GO or Dota at minimum.

Perfect for the optimal gaming PC

Now let's move on and see what AMD has. And here everything is interesting and not so unambiguous, because you can find a six-core Ryzen 5 2600 a little cheaper on the market, which, due to multithreading and overclocking, looks preferable in resource-intensive applications. In turn, the Core i5-9400 in modern games produces a higher level of FPS. Moreover, not only in comparison with the six-core Ryzen 5, but even in comparison with the eight-core Ryzen 7. Based on this, it is worth making a choice. Such a chip can pair well with a GTX 1070 or Radeon RX 590 for the ultimate gaming PC.
