Intel Core i9-12900HX vs Intel Core i9-14900HX: Comparison
Core i9-12900HX vs Core i9-14900HX: the total cores difference
These two are close on paper, and total cores is the only measure that separates them at all: Core i9-12900HX 16 against Core i9-14900HX 24. Add l3 cache to that, 30 MB on the Core i9-12900HX versus 36 MB on the Core i9-14900HX, and the pattern holds. P-core base clock is not the same on both, 2.3 GHz on the Core i9-12900HX versus 2.2 GHz on the Core i9-14900HX. There is a split on e-core base clock as well, 1.7 GHz on the Core i9-12900HX versus 1.6 GHz on the Core i9-14900HX. There is a split on release year as well, 2022 on the Core i9-12900HX versus 2024 on the Core i9-14900HX.
