doing 3D modeling, but that doesn’t
change the numbers.
If it’s any consolation, 11th-gen Tiger Lake
with 4 cores is basically as fast as a 10th-gen
Comet Lake U with 6 cores. That either says
Tiger Lake is great, or it says that Comet Lake
U just did not age well.
We also ran V-Ray Next 4.10.7, another
rendering benchmark. The 8-core Ryzen 7
4800U comes in 48 percent faster than the
11th-gen Tiger Lake.
In the Corona renderer, the Ryzen is 54
percent faster than Tiger Lake. We could go
on with other rendering tests, but we’d be
wasting your time and our time. The truth is
that despite losing in lighter tasks, Ryzen
4000 simply crushes it in heavy, multi-
threaded tasks.
Despite Intel’s proclamations that no
one does 3D rendering on a 3-pound
laptop with a tiny 14-inch screen, the core

count advantage extends to other areas

too. We didn’t do advanced encoding

using the integrated video engines of the

chips, but we did do a file conversion

using an older version of HandBrake. You

can set HandBrake to use the video

engines in new chips, or you can use the

cores too. Many older applications still

use cores.

The result is no surprise: While Tiger

Lake easily beats its siblings, the Ryzen

crushes it again, taking about 34 percent

less time to convert our 1080p file. The

basic summary is that if you need core

count, Ryzen wins every time.

Intel would say the brave new world is about

AI, which can be used to upsample images,

or sort your terabytes of photos for you.
