Earlier today, AMD's upcoming mobile CPUs leaked and now it's Intels turn, as its soon to be announced 12th Gen Alder Lake mobile parts in the H and U-series have both leaked, courtesy of VideoCardz. These will be Intel's first mobile CPUs with efficiency cores and every single SKU gets at least four of them. When it comes to performance cores, things are a lot more complex, as we're looking at everything from six performance cores, to a mere one for the Pentium and Celeron parts.

Starting with the H-series chips, Intel is set to release a pair of Core i9 parts, three Core i7 parts and three Core i5 parts. The Core i9's have 14 cores, divided between six performance cores and eight efficiency cores and a total of 20 threads. Intel is aiming for the same 5 GHz max turbo frequency as AMD, but Intel's max GPU frequency is a lot lower at a mere 1.45 GHz, compared to 2.4 GHz for AMD's parts. The Core i7's have two nearly identical SKUs, just with lower clock frequencies, but also a 10 core version, that loses four of the efficiency cores and gets a weaker GPU. The Core i5 parts start at 12 cores, of which four are performance cores, with the last SKU only having a total core count of eight. Oddly enough the two higher-end Core i5's have a more powerful GPU than the lowest tier Core i7. All H-series CPUs have a 45 W base TDP, with a boost TDP of between 95 and 115 W.
