shot on a Kodak video camera and upscale it
from 720p to 1080p, using the app’s Gaia
HQ preset.
This upscale would typically be done on a
GPU, where it would be significantly faster, but
we ordered it to use the CPU cores for the
upscale. Topaz Labs uses Intel’s own OpenVINO
for the Deep Learning. Doing a frame-by-frame
upscale isn’t easy and still takes literally hours to
complete. The Ryzen 9 finishes with about a
five-percent advantage over the Core i9. Too
close for comfort, but a win is a win.

PERFORMANCE
Moving on to compression and
decompression performance, we first use
RARLab’s WinRAR. As with prior Ryzen CPUs,
the result is bad—a loss for the Ryzen 9 and a
big win for the Core i9. The Ryzen
architecture has long performed poorly here.
In the built-in benchmark, the Core i9 is 82
percent faster.
Switching WinRAR to single-core
performance, nothing changes except the
Core i9’s win grows to a 194-percent
advantage. We use WinRAR because it’s worth

It’s too close for comfort for the Ryzen 9: The Core
i9 comes within 3 percent of its performance.

No surprise, the Core i9 walks away with a big
win here because the Ryzen part just runs poorly
in WinRAR.
