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?

    Re: Ice Lake GPU Underperforming? [soylentnews.org]

    15W/25W TDP laptop CPUs with integrated GPUs are clearly no problem at all if they can do stuff this. The 45W TDP laptop chips are often shipping alongside a discrete GPU.

    Some caveats apply. Intel's understanding of "TDP" is tortured at best, particularly on the desktop. And this CPU will be boosting to 5.3 GHz for... tens of milliseconds? It's mostly for marketing.

    If you want to compare performance-per-dollar, a desktop may be better than a "gaming laptop", although it might not be a huge win. You get a display with a laptop, and these laptop CPUs can hold their own against comparable desktop CPUs. Monolithic CPUs (such as Renoir) are more efficient than chiplets (Matisse), and there are results [wccftech.com] like the Ryzen 7 4800HS [wikichip.org] beating the Ryzen 7 2700X [wikichip.org], which is not that much older and has a much higher TDP.

    Intel is going to need these overclocked, overheating laptops if they hope to compete with AMD for the next couple of years.

    I'm not worried about Intel though. They have plenty of fanatics that will buy them anyway.

    Sure, I've had 125W notebooks that "worked" - but, why, today would you want such a beast?

    The fans suck in dust, the whole thing is super dependent on the cooling system, and you can get sufficient compute power for under 10W- so why would you make these huge real problems for a small edge in compute power?

    If you want to train neural nets, or compile giant API libraries from source, offload that to a 100W+ hardwired big box where it belongs. If you want a laptop, what do you value more: 50% reduced compile times, or 4.5x longer battery life?

      I would surmise (and 67% of all statistics are made up!) that most work laptops spend 85% of the time plugged in at a desk, 5% at starbucks and 10% in pointless meetings where the majority of participants would rather be back at their cubicles doing actual work.

      Give me a properly cooled quiet desktop any day but obviously that's incompatible with the hotdesking & take work home culture.

        Mine has spent probably 99%+ of the time on the desk plugged in. At least it's a high end laptop that gives desktop-like performance, but I'm tired of hearing the stupid fan spin up and down all day. Their solution to that is to change the office to an open plan layout, where there will be far too much noise around to hear something like a cooling fan.

        It's also one of the machines left still running Windows 7. It's old enough that I'm going to guess when IT gets around to upgrading everyone to Windows 10 they'll decide to just replace it instead. I'm planning on asking for a desktop.

        My laptops do indeed spend 95%+ of their time plugged in at my desk, sitting beside a real keyboard connected to a real computer with a real 25" or 30" monitor that I actually use 90%+ of the time. However, at home the laptop carries the "corporate approved" image with the VPN connection, and occasionally is required to make some of the corporate conferencing software work. And, at work, when it's time to look busy at a meeting, that laptop is indeed unplugged and run on battery for an hour or two, because schlepping a power brick and crawling around on the floor for an open outlet is... not fun.

    Even at 60W per core, you're looking at 50A of current per core...

    Aren't load bearing power 12 V? Shouldn't that be 5A of current?
