The Intel Core i7-10700K is a high-end desktop CPU based on the Comet Lake architecture. The CPU offers 8 cores and 16 threads clocked at 3.8 - 5.1 GHz. The TDP is rated at 125 Watt (PL1) but the PL2 is set to 229 Watt for short term boosts (up to 56 seconds).
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.
The Intel Core i5-10400F is a mid-range processor for desktops with six cores based on the Comet Lake architecture (CML-S, 4th generation of Skylake). The processor clocks at between 2.9 and 4.3 GHz and can execute up to 12 threads simultaneously thanks to Hyper-Threading.
The processor is still manufactured on the old 14nm (14nm++) process.
The Comet Lake architecture is similar to Coffee Lake and offers the same features and is made with the same 14 nm process. Other than the improved clock rates, the memory controller now also supports faster DDR4-2666 RAM. More information on Comet Lake and all the models and articles on it can be found here.
Performance
The average 10400F in our database matches the Ryzen 7 4800U and also the Core i7-9700K in multi-thread performance to be a more than decent mid-range option for your gaming rig, as of early 2022.
Graphics
The CPUs with an "F" suffix do not feature an integrated graphics adapter. The Intel UHD Graphics 630 iGPU is deactivated.
Power consumption
This Core i5 has a default TDP (also known as the long-term power limit) of 65 W which is in line with most desktop chips.
The i5-10400F is built with one of the old 14 nm Intel processes for poor, as of mid 2023, energy efficiency.
