10 PCWorld OCTOBER 2020NEWS INTEL LAUNCHES TIGER LAKE CPU
There’s a possibly
significant difference in
operating power. Ice
Lake’s U-series chips
offered a 15W nominal
TDP and a 25W “up”
TDP, allowing for higher
frequencies and
performance
differences. The
information Intel
released doesn’t make
that distinction. Intel
hasn’t said whether the
12W-28W UP
processors indicate a nominal TDP of 12W, or
whether they’re 15W parts with a TDP “down”
option of 12W. Intel could be offering laptop
makers the option of buying a single processor,
and running it in either an upclocked,Lake’s Core i3-1125G4 (2GHz base, 3.7GHz
single-core turbo, 3.3GHz all-core turbo).
Actual performance will vary, and will need to
be established via testing.
Intel isn’t offering as much processor
choice as in Ice Lake,
as there are five UP
Tiger Lake
processors (versus
six Ice Lake-U chips)
and four UP4 Tiger
Lake processors
(compared to five
Ice Lake Y-series
chips). Intel may
identify the lower-
power UP4 chips
with model numbers
ending in zero.Last year, Intel showed a Tiger Lake motherboard at CES.Here’s the Platform Controller Hub, or chipset, for Tiger Lake notebooks. It will
enable the peripheral I/O and other options seen here.
