46 PCWorld NOVEMBER 2020REVIEWS PREVIEW: INTEL 11TH-GEN CORE I7-1185G7 TIGER LAKE
When Intel first started talking about desktop
and laptop-based AI years ago, the actual
applications that used it were nowhere to be
found. Today, however, we’re in far better
shape. As much as AMD fanboys want to
dismiss AI performance, it is as valid to look
at as multi-core performance.
For our tests, we used three consumer
applications already on the market. The first is
Nero AI Photo Tagger. It’s currently free and
uses Intel’s open-source OpenVINO to
implement Deep Learning Boost on chips that
support it. To test it, we took 4,200 photos
taken with DSLR and camera phone and
tasked AI Photo Tagger to sort through them
and identify what’s in the pictures.
When it’s done, AI Photo Tagger spits out
two numbers: the total time spent to do the
job, and the total amount of AI time spent on
each recognizing each image. Total timeincludes loading the image, performing the
preview, and other housekeeping tasks. In
total time the 11th-gen Tiger Lake takes about
13 percent less time than the Ryzen 7 4800U
set to its 28-watt setting with Dynamic Tuning.
Give the Tiger Lake a little more power, and its
lead opens up to about 20 percent.
But as we said, the application also breaks
down how long it takes each CPU to recognize
the photo. The 11th-gen Tiger Lake actually
takes 40 percent less time than the Ryzen 7
4800U, and 57 percent less time than the
14nm, 6-core 10th-gen Comet Lake U.
The second AI task was Topaz’s Gigapixel
AI. The application uses AI to upscale images
in a manner that is generally superior to
simpler algorithms used in photo
applications. For this test, we took a single
picture of a P-38 fighter shot on an EOS 1D
Mk IIn DSLR. The camera is ancient and itIntel Ref 4/8 Tiger Lake (Core i7-1185G7/Iris XE) 41W PL1+ DT
