Intel Core i9-12900H Alder Lake CPU with 20 threads

Intel preparing 12th Gen Core H-Series for next-gen laptops.

It has been only 5 months since the launch of the 11th Gen Core Tiger Lake-H(45) series and we are already finding leaks on their successor, Alder Lake-P (H45). The new processors will be based on Golden Cove and Gracemont hybrid architecture with up to 14 cores.

The leak-over at Ashes of the Singularity Benchmark appears to confirm that the Core i9-12900H SKU will feature 20 threads. The software incorrectly lists 20 cores though, probably due to the fact that Gracemont (Efficient Cores) does not support hyper-threading. The Core i9-12900H features 6 Performance and 8 Efficient Cores (14 in total).

The CPU was paired with 16GB of memory, however, neither the clock of the processor nor the memory are listed. Therefore it is unclear if the CPU was using DDR5 or DDR4 technology.

Intel is now rumored to introduce its new Alder Lake mobile series in the first quarter of 2022, alongside its highly-anticipated Arc Alchemist discrete graphics. Interesting thought, the first leak with Alder Lake-P features NVIDIA GeForce RTX 3080 Laptop GPU, not even a SUPER variant which was also rumored to launch at a similar timeframe.

It is worth noting that the Alder Lake-P series will not represent the flagship performance in the next-gen Intel mobile stack. The company is also expected to introduce Alder Lake-S mobile with TDP up to 55W and 16 cores (8 Golden Cove and 8 Gracemont).
