The Intel Core i5-12600K is a mid-range CPU for desktops based on the Alder Lake architecture. It was first announced in November 2021 and offers 6 performance cores and 4 efficiency cores. The performance cores (P-cores) support HyperThreading, leading to 16 Threads that can be processed at once. The performance cores can clock with up to 4.9 GHz, the efficiency cores can clock with up to 3.6 GHz. All cores can use 20 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 1.45 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 12600K in our database is way ahead of the Ryzen 9 3900 and the Core i9-10900K, as far as multi-thread benchmark scores are concerned. This is a very fast CPU that should have no trouble running triple-A games for at least a couple of years.
Power consumption
This Core i5 series chip has a Base power consumption of 125 W, with its maximum Intel-recommended Turbo power consumption sitting at 150 W.
The i5-12600K is built with Intel's fourth generation 10 nm process marketed as Intel 7 for lower-than-average, as of mid 2023, energy efficiency.
The Intel Core i9-11900KB is an Octa-Core-CPU that was used in the Intel Beast Canyon NUC. It is based on the Tiger-Lake-H45 series and was announced in the second quarter of 2021. The processor cores can clock from 3.3 to 5.3 GHz, all cores at once can reach up to 4.9 GHz. The CPU features 24 MB level 3 cache and DDR4-3200 memory. The integrated UHD graphics card is based on the Xe-architecture with 32 cores and clocks up to 1.45 GHz.
As with the slower Tiger Lake-H CPUs, the 11900KB has a partly integrated WiFi 6E and Thunderbolt 4 in the chip. Furthermore, the 11900KB supports 20 PCIe 4.0 lanes.
The TDP is rated at 65 Watt with 3.3. GHz base clock and can be configured to 55 Watt (cTDP-down).
