With four cores and 3.5 GHz maximum clock, the Core i5-7400 is the most basic CPU of the new Core i5 seventh-generation series, codenamed Kaby Lake. Let’s test it!
Recently, Intel launched the seventh generation Core i processors, codenamed Kaby Lake. At first, were launched the Core i7 and Core i5 CPUs, and soon after, the Core i3, Pentium, and Celeron models. Those processors bring small changes compared to the sixth-generation ones: new video decoder for 4K video, improved Speed Shift technology (that dynamically adjusts the CPU clock,) and support to Optane technology (which is a future kind of high performance SSDs.)
The Core i5-7400 features 3.0 GHz base clock, 3.5 GHz turbo clock, 6 MiB of L3 cache, TDP of 65 W, and locked multiplier. It is manufactured under 14 nm process.
In term of price, the direct competitor of the Core i5-7400 is the Ryzen 5 1500X, which we will be reviewing soon. In this test, we compared the tested CPU to the Core i5-6500, which is a similar model from the previous generation. We also included the Core i5-7600K and the Ryzen 5 1600X, which are CPUs from a higher price range.
Figure 1 shows the box of the Core i5-7400.

We used a GeForce GTX 1080 video card on all tests.
Let’s compare the main specs of the reviewed CPUs in the next page.
