Earlier this month, I found a new Chrome OS baseboard dubbed Drallion that had chipset references to CML. Comet Lake chipsets and I see updated Chromium code recommends
Let's turn to Intel's Comet Lake information before discussing what it wants to bring to Chromebooks. AnandTech has a 14-nanometer process, which are officially 10th-generation processors but still use a 14-nanometer process. Intel's Previously Announced IceLake Chips, by comparison, use a 10-nanometer process:  More Regardless, Intel says, "It helps to reduce power consumption."
U-Series chips. Chromebooks built on the Drallion baseboard:
The 8th-gen chipset is used in recent high-end Chromebooks and the Pixel Slate , there are both U- and Y-Series processors. Power consumption appears to be a little bit lower on the new Comet Lake chips and some variants have more processor cores and threads than the previous generation. Unfortunately, Comet Lake processors do not get Intel Iris graphics;
Regardless, as I previously noted, Comet Lake paired with Intel Harrison Peak Wi-Fi brings Wi-Fi 6 for faster wireless data transfer speeds, provided you have a Wi-Fi 6 router. The chipset supports LPDDR4X memory which can transfer data at 4266 Mbps. There's no guarantee we'll see this speed in Chrome OS devices, but at least the baseboard and chipset are capable of using them.
this month, I'd be shocked if I saw the end of the Comet Lake Chromebook by next summer. My thinking: It's a second-half of 2020 device.
