If it's possible to find a laptop that can handle such a processor at max turbo, so far none of the options that house the 9880H can actually keep the processor from throttling, then that's great. But most options are enthusiast-grade and beyond what extremist payers are willing to pay imo.
I like the idea of this processor but as so many others have said, it doesn't matter how well you refine a 14nm processor with the same architecture, it can only get so efficient. If you run the older i7-8750H as per it's specs, not using the boost, as a 45w CPU, it sits at around 2.8GHz across all twelve threads! That's all!
Now you know why most laptops usually set the 8750H and 9750H at 55w, which pushes each up to around 3.5/3.6GHz, which is far better across the board. The issue is that most laptop heatsinks can handle MAYBE 140w for a combined CPU and GPU load, which is not much. Bob Of All Trades on YouTube makes a seriously good argument, which is where my statements are also coming from. He makes a good point.
Ultimately it boils down to whether or not this newer chip is worth its time and/or Ryzen mobile lineup coming out will bring the necessary competition to 'heat things up'. AMD is outselling Intel ten to one in desktop CPU sales around the planet, so here's to hoping we see better options cropping up in laptops and at least equal sales numbers when things get rolling.
