In the no-surprise category, we see the

12-core Ryzen 9 3900X simply demolish the

8-core Core i9-9900K to the tune of 42

percent. With 40 percent more threads at its

disposal, we kinda expected this. Still, this is

impressive performance and to be lauded.

Perhaps more important is the single-

threaded performance of the Ryzen 9 3900X.

With a boost clock of 4.6GHz on the Ryzen 9

3900X versus the boost clock of 5GHz on the

Core i9-9900K, that gives the Intel part about an

8 percent clock advantage in pure clock speed.

well. We’ll explore this in greater depth in
another story, but for now note that running
with MCE off tends to hurt Intel CPUs more
than running with PBO off on AMD CPUs.

MODELING PERFORMANCE
Up first is the old standby of Maxon’s
Cinebench R15. This benchmark is built on
the same engine used in Maxon’s Cinema 4D
modeling and animation application. Cinema
4D is also built into Adobe’s Premiere and
After Effects applications.

No surprise: 12 cores easily outguns 8 cores,
making the Ryzen 9 3900X the easy winner here.

The Ryzen 9 3900X essentially runs the Core i9 off

the field in multi-threaded performance.
