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.The U-series parts consist of two Core i7's, two Core i5's and one each of a Core i3, Pentium and Celeron branded SKU. Here we're looking at two, or as mentioned, a single performance core for the Pentium and Celeron SKUs. The Core i7's and i5's all get eight efficiency cores, whereas the remaining SKUs get four. The Core i7's boost to 4.8 or 4.7 GHz, whereas all the remaining processors, except the Celeron, boost to 4.4 GHz. The Celeron oddly enough doesn't support any boost speeds at all and is stuck at a mere 1.1 GHz for it's performance core and 900 MHz for its efficiency core. All the CPUs have a base TDP of 15 W, with a max boost TDP of 55 W, which oddly enough apparently also includes the Celeron part. The GPUs offer a max boost frequency of 1.1 to 1.25 GHz, depending on the SKU.

Admittedly the Gracemont CPU cores aren't bad performers and we expected Intel to take advantage of them for their mobile CPUs, but the U-series is looking a bit anemic compared to AMD's offering which includes up to eight "full fat" CPU cores even in its U-series of CPUs. Intel does have a lot more SKUs on its side though, as well as slightly higher clock speeds. It'll be interesting to see what the real world performance is going to be like, but it looks like Intel might be ahead with its H-series parts, assuming the performance is similar to Intel's desktop parts.
