The upcoming Intel Alder Lake-S desktop processors are expected to be released at the end of third quarter of 2021. Recently, Igor Wallossek has published a datasheet for the upcoming 12th Gen Core Intel processor – Intel Core-1800, could be the upcoming flagship i9-12900K.
The CPU has a relatively low base clock of 1800 MHz. The datasheet confirms that the Core-1800 sample will boost up to 4.6 GHz with two cores, up to 4.4 GHz with 4 and 4.2 GHz with 6. An all-turbo boost is 4.0 GHz. The datasheet does not mention Atom cores clock speeds, but it is said in the article that it will boost up to 3.4 GHz, but only with half of the cores (this sample has 8 in total). Igor claims that these specifications were reported with a voltage of 1.3147V.
