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.

COMPRESSION

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

Cinegy Cinescore 10.4

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.
