CPU PERFORMANCE
With graphics out of the way, we move onto
the choppier waters of CPU testing. We have
no doubt that Intel wins graphics, but on the
other side of the aisle it’s more nuanced.
We’ll kick this off with the good news for
Intel: awesomely high clock speeds. With the
Core i7-1185G7 capable of hitting 4.8GHz on
boost, and 4.3GHz on all cores, it’s hands-
down the winner on lightly threaded tasks.
You can see this in one of the tasks that
typically leans on frequency more than core
count: Microsoft Office. When paired with
Microsoft Office, PCMark 10’s Applications
test runs the computer through Word, Excel,
PowerPoint, and Edge and measures its
response doing mundane office tasks. It’s
about as real-world as you can get because
you’re actually using Microsoft Office.
The 11th Core i7-1185G7 comes in about


24 percent faster than the lower-clocked
10th-gen Ice Lake Core i7. In a reversal, the
10th-gen Comet Lake Core i7 using the older
14nm cores actually outpaces the 10th-gen
Ice Lake chip. Why? We suspect the reason
the 6-core 10th-gen Comet Lake U is faster is
its higher boost clock compared to the
10th-gen Ice Lake. It’s not enough to beat the
new 11th-gen Tiger Lake, which has a
16-percent advantage over it.
Ryzen 7 4800U boasts more cores, but it
also can’t hit clocks like Intel can, which we
think is the reason the 11th-gen Core
i7-1185G7 comes in 30 percent faster than
Ryzen. That’s a hands-down win for the
11th-gen chip.
One thing we want to note: While it’s
demonstrably faster in the results, is it really
something you’d notice while you churn
through an email about TPS reports or work
on an Excel spreadsheet for corporate
accounting? That’s hard to say, but the
numbers, at least, give 11th-gen Tiger Lake
the win.

MAYBE CINEBENCH AIN’T
SO BAD, INTEL
Intel has long argued that Cinebench is
mostly irrelevant to those who use 13-and
14-inch laptops, because less than 1 percent
of people actually do 3D modeling on a tiny
laptop. That’s a fair point, but you can also use
Cinebench to measure single-threaded
performance. We use the newest version of
