Intel Core i7-12700K vs Intel Core i9-12900 vs Intel Core i7-12700F

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.

Intel Core i9-12900

The Intel Core i9-12900 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 8 efficiency cores. The performance cores (P-cores) support HyperThreading, leading to 24 Threads that can be processed at once. The performance cores can clock with up to 5.1 GHz, the efficiency cores can clock with up to 3.8 GHz. All cores can use 30 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 (most likely only using AVX2). 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 integrated graphics card is based on the Xe-architecture and called Intel UHD Graphics 770. It clocks between 300 and 1.55 GHz.

The CPU is rated at 65 W base power and 202 Watt maximum Turbo power. It is manufactured in 10nm, called Intel 7, process at Intel.

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.
