Today, Intel is launching a new series of 14nm notebook CPUs code-named Comet Lake. Going by Intel's numbers, Comet Lake looks like a competent upgrade to its predecessor Whiskey Lake. The interesting question—and one largely left unanswered by Intel—is why the company has decided to launch a new line of 14nm notebook CPUs less than a month after launching Ice Lake, its first 10nm notebook CPUs.

Both the Comet Lake and Ice Lake notebook CPU lines this month consist of a full range of i3, i5, and i7 mobile CPUs in both high-power (U-series) and low-power (Y-series) variants. This adds up to a total of 19 Intel notebook CPU models released in August, and we expect to see a lot of follow-on confusion. During the briefing call, Intel executives did not want to respond to questions about differentiation between the Comet Lake and Ice Lake lines based on either performance or price, but the technical specs lead us to believe that Ice Lake is likely the far more attractive product line for most users.

Intel's U-series CPUs for both Comet Lake and Ice Lake operate at a nominal 15W TDP. Both lines also support a "Config Up" 25W TDP, which can be enabled by OEMs who choose to provide the cooling and battery resources necessary to support it.
