Intel Core i5-13400F vs Intel Core i5-9400F vs Intel Core i5-13400

The Intel Core i5-9400F is a six-core desktop processor based on the Coffee Lake architecture introduced in October 2018 along with the flagship Intel Core i9-9900K. The processor clocks at 2.9-4.1 GHz and can process up to 6 threads simultaneously. The Intel Core i5-9400F is manufactured in the improved 14-nm process (14nm++).

Performance

Compared to the Intel Core i5-8400, the performance could only be increased slightly. Performance increases of up to 10 percent can be expected. Both processors (old and new) still do not offer hyperthreading. The performance increase therefore only adds up to small architecture improvements and a slightly higher basic and turbo clock rate. This CPU is suitable for everyday office use, which does not require large coolers due to the low waste heat. But games are also among the application areas, because in games the Intel Core i5-9400F clearly beats the Intel Core i3-9100F. Here the six cores are paying off in the meantime. 

Graphics unit

The Intel Core i5-9400F is a processor without integrated graphics unit. If you value an iGPU, you should take a closer look at the Intel Core i5-9400, as it offers the entry level Intel UHD Graphics 630.

Power consumption

Intel puts the Thermal Design Power (TDP) at 65 watts. This means there is no need for large cooling systems, which also allows installation in very compact housings.

The Intel Core i5-13400 is a top modern and fast desktop processor and belongs to the current Raptor Lake series. The processor was introduced early 2023 and offers a base clock of 2.5 GHz. It reaches up to 4.6 GHz in Turbo mode. As with Alder Lake-S, Raptor Lake-S is also based on a hybrid design that combines P and E cores. The Intel Core i5-13400 therefore offers 6 P-cores and 4 E-cores, which can process a total of up to 16 threads in parallel. The processor continues to be manufactured using the 10 nm production process (called "Intel 7"). The Intel Core i5-13400 does not have a freely selectable multiplier. The LGA 1700 socket introduced with the Alder Lake series serves as the basis. The Intel Core i5-13400 can be based on either a Raptor Lake or Alder Lake chip. Initially, however, Alder Lake chips will be supplied.

Performance

Compared to the Intel Core i5-12400, the IPC of the new Core i5-13400 has been increased slightly. Nevertheless, there are now also 4 e-cores, which support the processor in terms of multi-thread performance. This puts the Intel Core i5-13400 at the level of an Intel Core i5-12600K, which also offers a total of 16 threads.

Graphics unit

The Intel Core i5-13400 is a processor with an integrated graphics unit, but it is only suited for office use or very old and low demanding games.
