The complete Ice Lake 10th-generation Core lineup.

(go.macworld.com/dpdv) into the
architecture, and an early hands-on
performance preview (go.macworld.com/
pfpv). If you want a lot of detail about Ice
Lake, I suggest reading those. Here, we’ll
give you a high-level overview of what we
might expect if and when they end up in a
future MacBook.

CPU: LOWER CLOCKS, BUT
BETTER PERFORMANCE
Intel launched eleven new 10th-generation
processors. Five are Y-series processors,
with a nominal TDP (thermal design power)
of 9 watts. Note that this is an increase
from the 5-watt TDP of earlier Y-series
processors, though the only MacBook to
currently use one, the MacBook Air (go.

macworld.com/18ar), comes with a Core i

8210Y that has an unusual TDP of 7 watts.

Still, if the MacBook Air were to get a new

processor, it would almost certainly be a

Core i5 variant of one of these Y models,

with 4 cores and 8 threads.

There are six U-series processors, with a

TDP of around 15 watts (save for the top-end

Core i7 1068G7 model with a 28-watt TDP).

This is the class of chips that ship in 13-inch

MacBook Pros.

Intel’s new Sunny Cove CPU

microarchitecture features a number

of improvements over the Skylake

microarchitecture found in its CPUs for

the last few years. It’s designed to be

“deeper and wider” with new instructions

to speed up cryptographic and large
