The Core i9-12900H for laptops

In 2022, Intel will roll out its Alder Lake generation for laptops. These new processors will also be based on the Golden Cove and Gracemont hybrid architecture with up to 14 cores. The top of the line of this twelfth generation will be represented by the Core i9-12900H . It should offer 14 cores and 20 threads (6 performance cores and 8 efficient cores).

Alder Lake H

You will note that the 12900H is the top of the range Alder Lake P but another series promises higher performance, Alder Lake-S with 16 cores and 24 threads but a TDP of 55W. The leak released by VideoCardz gives some information from the Ashes of the Singularity benchmark. It is difficult to draw any real conclusions from it except to see that a portable platform associated with an RTX 3080 is in circulation. We also note that the processor is poorly recognized by the test (20 cores / 20 threads) and that it is associated with 16 GB of memory. However, neither the frequency of the processor nor the characteristics of the memory are listed. Therefore, it is not known whether the platform that accompanies the processor uses DDR5 or DDR4 technology.

i9-12900H

From a performance point of view and taking all the usual caveats on these leaks and the use of the AotS benchmark, we see a score of 107.6 FPS. Wanting to compare, we have to look for a similar score. In these figures we find a configuration consisting of a Core i7-11700K desktop paired with an Nvidia GeForce RTX 3080 and 64 GB of RAM. So if these figures are true, we would get almost the same result with a portable platform as on a desktop system. This Alder Lake-H processor with a TDP of 45 to 55 W would therefore be able to match a high-end gaming desktop PC that is a few months old…That requires verification.
