Intel Core i5-8600K vs Intel Core i7-12700K

Intel Core 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 i7-12700K

The Intel Core i7-12700K is a high end CPU for desktops based on the Alder Lake architecture. It was first announced in November 2021 and offers 8 performance cores and 4 efficiency cores. The performance cores (P-cores) support HyperThreading, leading to 20 Threads that can be processed at once. The performance cores can clock with up to 5 GHz (Turbo Boost Max 3.0), the efficiency cores can clock with up to 3.9 GHz. All cores can use 25 MB Smart Cache. The integrated memory controller supports up to 128 GB DDR5 with 4800 MT/s (dual channel).

Thread Director (in hardware) can support the operating system to decide which thread to use on the performance or efficiency cores for the best performance.

The integrated graphics adapter is based on the Xe-architecture and called Intel UHD Graphics 770. It clocks between 300 and 1.5 GHz.

For AI tasks, the CPU also integrates GNA 3.0 and DL Boost. Quick Sync in version 8 is the same as in the Rocket Lake CPUs and supports MPEG-2, AVC, VC-1 decode, JPEG, VP8 decode, VP9, HEVC and AV1 decode in hardware.

Performance

The average 12700K in our database is way ahead of the Ryzen 7 5800X and the Ryzen 9 3900X, as far as multi-thread benchmark scores are concerned. Which is a very, very impressive result, as of late 2022.

Power consumption

This Core i7 series chip has a Base power consumption of 125 W, with its highest Intel-recommended Turbo power consumption sitting at 190 W. It might be a good idea to get an AIO cooling solution for a chip this power hungry.

The i7-12700K is manufactured on Intel's fourth-generation 10 nm process marketed as Intel 7 for lower-than-average, as of early 2023, energy efficiency.
