48 PCWorld NOVEMBER 2020REVIEWS PREVIEW: INTEL 11TH-GEN CORE I7-1185G7 TIGER LAKE
told actually flips it over to OpenGL mode.
We ran all the laptops in this mode, which
actually gives the Ryzen’s Radeon cores the
edge. The results make sense mostly, as the
Xe does a decent job while the older Iris Plus
lags a good clip behind. Over in the parking
lot next door and not even on the field is the
Intel HD graphics in the Comet Lake U chip.
Our final AI test uses Topaz Video
Enhance AI to convert a 720p video shot on
an old Kodak FLIP-style video camera to 4K
resolution. For the test we used the Theia
model to AI upscale the image.
Our thought is someone with an SD card of
old family videos and a 4K TV might want to see
these videos blown up to modern standards.
You can read Joel Hruska’s obsession (go.
pcworld.com/joel) with using Topaz Video
Enhance AI to create his own remastered
version of Star Trek: Deep Space Nine and seejust how cool AI-based upscaling can be.
The 11th-gen Tiger Lake takes a little under
two hours to AI-upscale our video, while the
Ryzen 7 4800U takes a little over five hours to
complete the task. The 10th-gen Ice Lake
wasn’t able to run Open VIno in Topaz
Gigapixel AI, but it seems to work here,
taking a little over three hours. The 6-core
10th-gen Comet Lake U, though? Yeah, it took
more than 11 hours to AI upscale the image.BOTTOM LINE
We’ll break down our takeaways for the
11th-gen Tiger Lake into three areas that
matter most for the consumer.
The first category is gaming. While Ryzen
7 4800U actually does pretty well, the clear
winner is the 11th-gen Core i7-1185G7 Tiger
Lake CPU. When you’re talking 30 percent
faster in games, that’s simply nothing to scoffTopaz Gigascale AI
