Intel Details 10th Gen Comet Lake-H for 45 W Notebooks: Up to 5.3 GHz*

Two of the big announcements out of CES this year were both mobile related: Intel and AMD announced they would be launching new gaming laptop processors into the market in the first half of this year. 45 W parts, also known as H-series in the business, provide the basis for productivity and gaming notebooks that use additional graphics to give some oomph. These systems span from thin and light with GPU requirements, through 'luggables' that are just about portable, all the way up to desktop replacement designs. Intel's newest 10th Gen H-Series are based on the Comet Lake family, the fifth iteration of Intel's 14nm Skylake designs, and they're going all the way up to 5.3 GHz*.

The new CPU list from Intel starts with the Core i9-10980HK at the top, with eight cores, sixteen threads, and all the focus is on that 5.3 GHz turbo frequency.

*This CPU can hit this frequency on two cores. However this has some specific requirements: the system needs to be within its secondary power limits, and Intel's Thermal Velocity Boost also needs to be turned on. The latter of which means that there has to be additional thermal headroom in the system, and that OEMs have designed for this and enabled it within the system. This allows the CPU to go from 5.1 GHz to 5.3 GHz. Every Intel Thermal Velocity Boost enabled CPU requires specific OEM support in order to get those extra two bins on the single core frequency.

The base frequency of this chip is 2.4 GHz, and it has a regular 45 W TDP (sustained power), which can be run in cTDP up mode for 65 W. Two other plus points on this chip is that it is unlocked, for when an OEM provides more thermal headroom, and it supports DDR4-2933, which is an upgrade over the previous generation. Intel's recommended PL2 (turbo power) for the Core i9 is 135 W, and Intel says the recommended 'Tau' is set to 56 seconds for the i9, and 28 seconds for all the other CPUs. OEMs don't often adhere to these values for notebooks, but they are provided as a guide. It does mean that in order to hit 5.3 GHz, the Core i9 is by default allowed to take 135 W across two cores, or 67.5 W per core. Even at 60W per core, you're looking at 50A of current per core... in a laptop.

Hot, or not?
