I wonder why Intel doesnt release a 4c/8t chip clocked at 3,2ghz and 30w. It would still be very portable but wouldnt reach its power limit all the time like these chips. It sucks that the option is eithet ULV 15w chip or 8300h 4c/8t 3,9ghz 45w chip.
Intel released those processors 3 quarters ago: Coffee Lake-U (28W)
Core i7-8559U 4C8T base 2.7 turbo 4.5
Core i5-8269U 4C8T b2.6 t4.2
Core i5-8259U 4C8T b2.3 t3.8
Core i3-8109U 2C4T b3.0 t3.6
And most importantly all have Intel's best IG: Iris Plus 655 with 128MB eDRAM, making the iGPU on par with AMD's integrated Vega 8 or so. I don't know why more laptop SIs don't use these chips. Probably because of 28W when 15W makes for a lighter cooler & laptop and most people are ignorant of GPUs anyway.
Currently the biggest customers of these chips are Intel themselves with the current 4x4" NUCs and Apple with the 13" MacBook Pro.
