Intel Core i5-8600K vs Intel Core i7-8700 vs Intel Core i5-8400

Intel Core i5-8600K

► remove from comparison Intel i5-8600K

The Intel Core i5-8600K is a high-end desktop processor with six cores based on the Coffee Lake architecture and was announced in September 2017. The processor clocks at between 3.6 and 4.3 GHz and can execute up to six threads simultaneously (no HyperThreading). According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process. The i5-8600K is comparatively easy to overclock thanks to the unlocked multiplier.

Performance

Due to the two additional cores, performance has increased significantly compared to the Core i7-7700K when all cores are in use. Single-core performance has not improved since its Kaby Lake predecessor. As a high-end model, the i5-8600K is suitable for the most demanding applications and games.

Graphics

The integrated Intel UHD Graphics 630 iGPU is basically identical to the previous generation Intel HD Graphics 630. Only some low demanding games are playable with this graphics card (see GPU page linked above).

Power Consumption

Intel specifies the TDP with 95 watts. Therefore, well-dimensioned cooling systems should easily manage to deal with the created heat. We expect increased efficiency due to the higher performance.

Intel Core i7-8700

► remove from comparison Intel i7-8700

The Intel Core i7-8700 is a high-end desktop processor with six cores based on the Coffee Lake architecture and was announced in September 2017. The processor clocks at between 3.2 and 4.6 GHz and can execute up to twelve threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process. Compared to the slightly higher clocked Core i7-8700K, the i7-8700 offers a lower TDP and no unlocked multiplier (no easy overclocking).

Performance

Due to the two additional cores, performance has increased by almost 50% compared to the previous quad-core Kaby Lake models. Single-core performance has not improved much. As a high-end model, the i7-8700 is suitable for the most demanding applications and games.

Graphics

The integrated Intel UHD Graphics 630 iGPU is supposed to offer higher performance as its clock rate has been increased by 50 MHz. The build is identical to that of the Intel HD Graphics 630. We do expect a performance improvement, but as a low-end solution it will probably only display current games smoothly at reduced details - if at all.

Power Consumption

Intel specifies the TDP with 65 watts. Therefore, well-dimensioned cooling systems should easily manage to deal with the created heat. We expect increased efficiency due to the higher performance.

Intel Core i5-8400

► remove from comparison Intel i5-8400

The Intel Core i5-8400 is a mid-range 6-core CPU. The processor belongs to the Coffee Lake generation and was presented in September 2017. It does not support Hyper-Threading, which means it can run six threads simultaneously. The base clock rate is 2.8 GHz and the CPU can speed up to 4.0 GHz under high load. Despite belonging to the new generation of CPUs, the Core i5-8400 is manufactured in an improved 14nm process.

Performance

The processor offers a strong performance increase compared to the Core i5-7400 due to its two additional cores. Single-core performance has not improved significantly compared to its Kaby Lake predecessor. As a mid-range model, the Core i5-8400 should be suitable for demanding games and programs.
