Intel Core i5-9400F vs Intel Core i5-1340P vs Intel Core i7-9700K
Intel Core i5-9400F
► remove from comparison
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.
Intel Core i5-1340P
► remove from comparison
The Intel Core i5-1340P is a mid-range Raptor Lake-P (Alder Lake-P refresh) family CPU, a 28 W part meant for use in ultra-light, ultra-thin (yet actively cooled) laptops. This CPU was announced in early 2023 and it has 4 of the 6 performance cores (P-cores, Golden Cove architecture) and 8 efficient cores (E-cores, Gracemont architecture). The P-cores are Hyper-Threading-enabled and clock from 1.9 GHz (base) up to 4.6 GHz (single core boost) for a total of 16 threads when combined with the E-cores. The clock speeds of the E-cores ranges from 1.4 to 3.4 GHz and offer a similar performance as the old Skylake cores.
The performance should be similar to the old Core i7-1250P and therefore well suited for even demanding tasks.
The CPU still only supports PCIe 4.0 x8 for a GPU and two PCIe 4.0 x4 for SSDs.
The i5-1340P is rated at 28 Watt tDP (PL1, 64 Watt PL2 for short bursts). The CPU is manufactured in the further improved Intel 7 process (10nm SuperFin).
Intel Core i7-9700K
► remove from comparison
The Intel Core i7-9700K is a high end desktop processor based on the Coffee Lake architecture. It offers an open multiplicator for easy overclocking and integrates 8 cores (no Hyperthreading therefore also 8 threads) clocked at 3.6 - 4.9 GHz and it needs a new Z390 based mainboard.
Thanks to the two additional cores, the performance in multi-threaded applications is even better than the old Core i8-8700K with 6 cores and Hyperthreading. As a high end desktop CPU, the i9-9700K is suited even for very demanding applications and perfect for 3D gaming.
The integrated Intel UHD Graphics 630 graphics card is clocked at up to 1.2 GHz and offers no advantage compared to previous generations. As it is a very low end GPU, only some low demanding games like Hearthstone can be played with it (see GPU page for benchmarks).
Intel specifies the TDP at 95 Watt, so if the CPU is used in laptops a big and chunky cooling system is needed to avoid throttling and lower clock speeds under sustained loads. When overclocking the CPU, the power consumption can easily rise up to 200 Watt and higher.
