Although the Intel Core i9-13900 processor is not yet available, Chinese artisans have obtained a copy of it and have even removed its cover.
The Core i9-13900’s die area measures 257.04mm vs. 208.08mm . Core i9-12900K has a 24% larger crystal. This is natural, as the technical process has not changed. The number of small cores has increased by two-thirds, while the cache memory has increased by 24%.
According to the source, the Core i9-13900’s maximum power limit is between 400-420 W. This is a significant increase over the 300-320W of the predecessor. However, it does not indicate how much power the new CPUs will use in real life conditions. They should also consume more because they have more cores and faster frequencies, while still maintaining process technology.
