Core i9-12900HK Alder Lake A Powerful Notebook CPU

Intel Alder Lake Core i9-12900HK CPU Specifications

The Intel Alder Lake H series processors feature the Core i9-12900HK as the flagship CPU, offering up to 14 cores, 24 MB of L3 cache, and a clock frequency of 5 GHz. The lineup is also going to be up to 40% faster than the previous generation, offering a big boost to content creators and gamers alike. In a Core i9-12900HK performance slide, the CPU can be seen beating both the Apple M1 Max and Ryzen 9 5900HX by offering much higher performance at the same wattage. It really shows that Alder Lake is going to give AMD and Apple a beating in the overall efficiency game and further extend the performance with a max turbo power of up to 115W.

As for overall performance, the Intel Core i9-12900HK is up to 28% faster in gaming and up to 44% faster in content creation versus the Core i9-11980HK and also easily beats the Ryzen 9 5900HX & Apple’s M1 Max / Pro chips. There are tons of options to select from too as these chips will power enthusiast-grade laptop designs.

As for thermals and power consumption, you are without looking at one power-hungry and a hot chip. Since thermals and power consumption vary from notebook to notebook and no model has been mentioned here, we think this might not be the best-cooled variant. The CPU hit a max temp of 99C while the average temperature was reported at 69C for the core and 76C for the package. The power consumption peaked at 113W but averages around 63W.

We also have to remember that the Intel Core i9-12900HK and Core i9-12900H are almost identical chips with the latter offering the same performance at a reduced power limit & with better temps. Also, Intel is giving away its efficiency by reaching for those 5 GHz clock speeds which sound good from a marketing standpoint. One thing is for sure that Intel’s Alder Lake-H laptops will easily beat AMD’s Zen 3 (Ryzen 5000H) and Zen 3+ (Ryzen 6000H) laptops with ease.

AMD had the guts to compare their Zen 3D CPU to Intel’s Alder Lake CPUs but they didn’t even compare their Ryzen 6000 APUs to Intel’s mobility lineup and their H-series was almost missing from the show (in terms of performance benchmarks). Even the Ryzen 6000U benchmarks were deceptive in comparison as they used a 15W (Ryzen 5000U) APU against a 28W (Ryzen 6000U) APU. AMD’s Zen 3+ might make for some nice mainstream and entry-level designs but Intel has a really strong notebook line with Alder Lake that will target them aggressively at all segments.
