Ryzen 3000 Review: AMD's 12-core Ryzen 9 3900X conquers its past

With its ground-breaking 7nm process, AMD's Ryzen 9 3900X leaves very little room for Intel's best CPUs.

Ryzen 9 3900X 3D 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.

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 vs. 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.

That’s impressive single-threaded performance for the Ryzen 9 3900X.

Not all megahertz are the same, though. With AMD’s much-improved instructions per clock—essentially how efficient the chip is—the Ryzen 9 is but 2 to 3 percent slower than the Core i9.

Cinebench R15, however, is fairly old, having come out in 2013, so we also measured all three CPUs using the new Cinebench R20. Intel generally is a bit faster in this updated test—against older Zen+ cores.

Shifting to the updated Cinebench R20, the Ryzen 9 3900X actually pulls ahead in single-threaded performance.

The situation changes for the Zen 2 cores in the Ryzen 9 3900X, resulting in a 3-percent bump in single-threaded performance. That’s a nice shift for AMD.

The tables turn for multi-threaded performance. The 12-core AMD part smashes the 8-core Intel part by 42 percent.

No surprise: The Ryzen 9 3900X essential runs the Core i9 off the field in multi-threaded performance.

We also tested the chips using Chaos Group’s Corona Renderer benchmark. Corona is a “modern unbiased photorealistic renderer,” which refers to the precision in which it renders the scene—not unbiased based on the hardware it’s run on.

The Corona modeler likes 12 cores more than 8 cores.

In this multi-threaded test, we see the Ryzen 9 outrun the Core i9 by about 32 percent. And yup, the body blows keep coming.

We run V-Ray Next, which is another renderer from the Chaos Group. The result? About 31 percent in favor of the Ryzen 9 over the Core i9.

Bored yet? V-Ray Next reinforces what we’re seeing in other modeling apps.

What about the free and popular 3D modeler Blender 2.80, using the intensive Gooseberry test file? How about 43 percent in favor of the Ryzen 9 over the Core i9.

Dayum. The Ryzen 9 3900X is fast.

We’ll close off the 3D tasks with the oldie, but goodie POV-Ray 3.7 benchmark. The Persistence of Vision Raytracer is an open-source, free tool that has roots in the Amiga platform. Using the application’s built-in test, we saw the Ryzen 9 about 44 percent faster than the Core i9 in multi-threaded mode.

What a shocker: The Ryzen 9 mops the floor with the Core i9.

POV-Ray also has a single-threaded benchmark, in which the Core i9 and its 5GHz clock ekes out a 4-percent win over the 4.6GHz Ryzen 9. A win is a win, but most are likely to say big whoop.

The 5GHz boost clock of the Core i9 gives it a very slight edge over the Ryzen 9 in POV-Ray when set to test a single thread.

Viewport Performance

Before we jump to the next section we did want to explore a protest we had heard from Intel fans though. We'll summarize it as "We know the simple math of 12 > 8 is true, but for 3D artists, the time waiting for rendering (when you might take a potty or coffee brak) is not as critical as the seat time when you actively need faster responsiveness. That is, system "snappiness" when trying to do precise modelling is just as important if not more important. In that world, the math of 5GHz > 4.6GHz so Intel wins in that department.

To try to test that theory we looked to CGDrector.com's free Cinema4D Viewport Performance benchmark. CGDirector is an PC enthusiast site dedicated to helping 3D artists make the right computing purchase choices for their job.

For a better interface or "viewport" experience for 3D artists, CGDirector said the CPU is the chief bottleneck—and not the GPU. That means chips with higher frequency and higher IPC typically are more important.

"In this Cinema 4D Viewport Benchmark, we measure the FPS of a typical Scene that uses common 3D Objects from Cinema 4D Objects in a hierarchy," the website said. 

For this test, we ran the Cinema 4D Viewport benchmark with a demo version of Cinema 4D R20.

Some of the results the site has posted register a 7th gen Kaby Lake Core i7-7700K with a boost clock of 4.5GHz at 1,049 and a 16-core Skylake X Core i9-9960X with a boost clock of 4.4GHz at 1,045. A Xeon X5450 with a relatively low boost clock of 3GHz scores 418 in the test. So how do our three perform in this viewport performance test?

Using CGDirector's Viewport Performance test, the Core i9 has the win but the Ryzen 9 isn't too far behind is it?

Since this test is new to us, we're going to be careful putting too much weight in it, but this is CGDirector.com's jam and we're going to imagine its test is what an actual 3D animation nerd is going to care about in viewport performance. Based on that, the Core i9 does win and if there is some truth (we don't see why not) to the theory that a 3D artists needs UI responsiveness more than heavy rendering wait times, Intel has the edge.

However, as we've seen elsewhere, the good news for the Ryzen 9 3000 is that even in a loss, it's not that far behind. And frankly, if you're looking for the best of both worlds with slightly slower Viewport performance but much, much greater rendering performance, the Ryzen 9 comes out in front. It's really up to the individual tastes of the artist.
