Intel Core i7-4790 vs Intel Core i5-12400

The Intel Core i7-4790, based on the Haswell S architecture, was introduced in 2014 and was designed for mainstream desktop systems that required robust performance for productivity and entertainment.

This processor was manufactured using a 22 nm process and features 4 cores and 8 threads. It is equipped with 8 MB of Level 3 cache, without a separate Level 2 cache. The maximum memory bandwidth reaches 26 GB/s, and it supports PCIe 3.0. The integrated graphics solution is Intel HD Graphics 4600. The Intel Core i5-12400, on the other hand, which came to market in 2022 with the Alder Lake S architecture, targets modern desktop users who demand high efficiency and performance for a wide range of applications.

Manufactured using the more advanced 10 nm process, it offers 6 cores and 12 threads. This processor features 8 MB of Level 2 cache and 18 MB of Level 3 cache. Its maximum memory bandwidth is 77 GB/s, and it offers support for PCIe 5.0. The integrated graphics is Intel UHD Graphics 730. In single-core performance, the Intel Core i5-12400 significantly outperforms the Intel Core i7-4790, which is due to its newer architecture and higher Instructions Per Cycle (IPC).

In multi-core applications, the Intel Core i5-12400 also shows significantly better performance, driven by its higher core and thread count as well as the optimized chip architecture. These performance differences are noticeable in all more demanding workloads. For gamers, the Intel Core i5-12400 offers a significantly better experience.

Its superior single-core performance is crucial for frame rates in many games, and PCIe 5.0 support enables faster communication with modern graphics cards. The higher memory bandwidth of the Intel Core i5-12400 also contributes to a smoother display. Thanks to its more modern 10 nm manufacturing process, the Intel Core i5-12400 is more energy-efficient than the Intel Core i7-4790, which was manufactured using a 22 nm process.

This leads to a better performance-per-watt ratio and potentially lower cooling requirements. Regarding value for money, the Intel Core i7-4790 is only relevant for use in existing, older systems, where it can be acquired cheaply used. The Intel Core i5-12400, however, offers excellent value for money for current new purchases or system upgrades, as it delivers high performance for a reasonable price and is available new in retail.

In summary, the Intel Core i7-4790 is suitable for basic tasks on existing hardware. The Intel Core i5-12400 is the superior choice for all modern requirements, from gaming to demanding productivity and content creation, thanks to its significantly higher performance, modern features, and better energy efficiency.
