Intel Core i7-11700K vs Intel Core i7-12700F vs Intel Core i7-12700

Intel Core i7-11700K

The Intel Core i7-11700K is a high-end desktop CPU based on the Rocket Lake architecture. The CPU offers 8 cores and 16 threads clocked at 3.6 - 4.9 GHz. The TDP is rated at 125 Watt (PL1, power limit sustained load) but the PL2 is set to around 250 Watt for short term boosts (up to 56 seconds). 

The Sunny Cove processor cores (known from the Ice Lake mobile CPUs) offer larger caches and an improved IPC (up to 19%). Furthermore, the chip also includes (partly) integrated WiFi 6E and Thunderbolt 4. The platform supports PCIe 4.0 and Intel DL Boost for AI acceleration.

The faster Rocket Lake-S CPUs also integrate a new Intel UHD Graphics 750 that is based on the current Intel Xe architecture (e.g. mobile Tiger Lake).

The CPU is manufactured on an old 14 nm process like the Comet Lake predecessors.

Intel Core i7-12700F

The Intel Core i7-12700F 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 4.9 GHz (Turbo Boost Max 3.0, 2.1 base), the efficiency cores can clock with up to 3.6 GHz (1.6 GHz base). All cores can use 25 MB Smart Cache. The integrated memory controller supports up to 128 GB DDR5 with 4800 MT/s (dual channel).

The 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.

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.

The F-series desktop models don't offer an integrated graphics card.

The CPU is rated at 65 W base power and 180 Watt maximum Turbo power. It is manufactured in 10nm, called Intel 7, process at Intel.

Intel Core i7-12700

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.
