Having recently unveiled the 10th Gen Ice Lake-U and Ice Lake-Y processors for low power notebooks, today Intel launched eight additional 10th Gen Core processors under the Comet Lake family. These are all based on the Skylake microarchitecture and make use of Intel’s 14nm process node as opposed to the 10nm process node that the Ice Lake processors used. The key change here is that Intel has now provided up to 6 cores in the sub-15W segment bringing a lot more performance to the table for the smaller form factors.
Intel launched both U and Y-series of processors for the 10th Gen Comet Lake family. These include 3 Core i7 SKUs, 3 Core i5 SKUs and 2 Core i3 SKUs. All of them utilise the same Intel UHD 620 IGP which has been around since 2017 and packs 24 Execution Units in all SKUs except in the Intel Core i3-1011U which supposedly has 23 EUs.
Compared to their Ice Lake counterparts, the Comet Lake Y-series SKUs have a nominal TDP of 7W which is lesser than the more optimised 10nm Ice Lake SKUs. This can be attributed to the fact that Ice Lake has a much better IGP which have twice as much EUs and thus, consume more power. All U-series processors have a configurable TDP going up to 25W and with the Y-series, the OEMs can push it to 9W. Overall, the nominal TDP for the Y-series has increased by 2W because of the added cores. Previous gen Y-series processors would have a nominal TDP of 5W with fewer cores.
Another key difference is that the Y-series only support LPDDR3 memory owing to older silicon. The U-series has support for LPDDR4X memory. You can find the Ice Lake SKU stack below.
