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.
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.
The Intel Core i7-12700F is a fast eight-core desktop processor based on the Alder Lake architecture, which was introduced in November 2021. The processor offers a base clock of 3.3 GHz and reaches up to 4.9 GHz in Turbo. In the same way, the Intel Core i7-12700K the Core i7-12700F is based on a hybrid architecture of 8P and 4E cores. The innovations of the Alder Lake-S processor compared to Rocket Lake, together with the smaller 10 nm manufacturing process, are clearly noticeable. The Intel Core i7-12700 does not offer a free multiplier, which means that overclocking is not possible.
Performance
Compared to the Intel Core i7-11700 , performance has been increased with a better IPC. The additional e-cores are also clearly noticeable in multi-threaded applications. Overall, this provides a noticeable performance boost, which also has an effect on all application areas. The 4 E-Cores provide the P-Cores with significantly more power. If all requirements are met, Intel Turbo Boost 3.0can increase the clock rate of the P-Cores to up to 4.9 GHz. The E-cores also offer a turbo and clock up to 3.6 GHz.
Graphics unit
The Intel Core i7-12700 is a processor with an integrated graphics unit. However, with the Intel UHD Graphics 770 there is only a simple iGPU which is only suitable for office use.
Power consumption
The TDP of the Intel Core i7-12700 is 65 watts, with the option to consume up to 180 watts in Turbo mode. If all restrictions are deactivated in the BIOS, the PL2 value can be achieved permanently. However, a high-quality and powerful cooling unit should be used for this.
