updates.
Due to time and other constraints, we ran
the boards with MCE and PBO set to Auto,
and 2nd-level XMP and AMP profiles
selected. While these factory settings are
beyond what is stock, we think it’s close to
what a consumer will see out of the box.

RENDERING PERFORMANCE
We’ll kick this off where we normally do:
Maxon’s Cinebench R20. It’s a 3D modelling
test built on the company’s Cinema4D
engine, and it’s integrated into such products
as Adobe After Effects. Like most 3D
modelling apps, more cores and more
threads typically yield more performance.
Our results for the Core i9-10900K and
Ryzen 9 3900X are fresh, but we decided to

sprinkle in results from previous reviews for

more context. Although those older results

are not using the latest version of Windows,

Cinebench is very reliable. The R20 version

uses AVX2 and AVX512 and takes about three

times as long to run as the older R15 version.

That means any boost performance should

matter less.

Remember these results, because for the

most part it won’t change too much as we

move through multi-threaded performance:

Cores matter. The Ryzen 9 3900X’s 12 cores

prevail over the Core i9-10900K’s 10. If it’s any

consolation, the latest Core chip fares

noticeably better than the Core i9-9900K and

Core i9-9900KS, which were both

handcuffed by their “mere” 8 cores.

Switching Cinebench R20 to

Cinebench R20 NT

The 10-core wasn’t expected to out-gun AMD’s
12-core but at least it’s closer.
