Ryzen 9 9950X And 9900X Review: AMD’s Flagship Zen 5 Chips Tested
Running AI workloads natively on local hardware, or at the edge instead of in the cloud, is just now emerging into the mainstream on PCs. As a result, reliable, easily repeatable benchmarks for these workloads aren't prolific just yet, though UL has already built a few into its Procyon benchmark suite.
UL Procyon AI Machine Vision Benchmark

This was a somewhat quizzical result. This computer vision benchmark is affected not only by CPU processing throughput, but latency, memory bandwidth and memory capacity as well. Surprisingly, the Ryzen 7 9700X finishes on top, followed by the Ryzen 9 9950x and 9900X. We suspect latency between the dual CCDs on the Ryzen 9 chips negatively impacted performance versus the single, fully-enabled 8-core CCD on the 9700X, but are not certain. We've reached out to UL for some insight.

Blackmagic RAW Video Encoding Speed


The Blackmagic Speed Test liked the increased cache on the Ryzen 9 7950X3D, at least in regard to the more compressed 12:1 tests with both 4K and 8K footage, where the 7950X3D managed to outpace the Ryzen 9 9950X and 9900X. Ultimately, the new Ryzen 9s outran their previous-gen counterparts by a few frames per second, but the deltas aren't particularly large and Intel maintains an overall lead in this applications.

You'll notice there are only AMD systems in the chart above. Unfortunately, the MSI motherboard we used in our 14th Gen Intel test rig doesn't perform as expected when HPET (the High Precision Event Timer) is enabled, and HPET is required to run this test. HPET works properly on our Socket AM5 Asus mobo, though, hence all of the Ryzen results above.
As you can see, the Ryzen 9 9950X and 9900X outperform their previous-gen counterparts by a few percentage points, but even with Zen 5's IPC improvements, there's no making up for additional cores in a video rendering workload like this one.
Cinebench 2024 Rendering Benchmark

Cinebench 2024 loves these higher-powered Ryzen 9 chips. The Ryzen 9 9950X took the top spot, in both the single and multi-threaded tests and the Ryzen 9 9900X edged out the Core i7-14700K and clearly outran the previous-gen Ryzen 9 7900X.
POV-Ray CPU Ray Tracing Benchmark
Our results with POV-Ray are much more competitive. Here, the 14th Gen Intel Core processors put up the best single-threaded scores, but the Ryzen 9 processors scale better as core counts increase and the Ryzen 9 9950X ends up in the top spot once again. The Ryzen 9 9900X wasn't able to catch the Core i7, however.
Blender Rendering Benchmarks
Blender is a free and open source 3D creation suite that can handle everything from modeling, rigging, and animation to simulation, rendering, compositing and motion tracking. It has a purpose-built benchmarking tool that will track the time it takes to complete rendering a particular model (or models). We used the CPU-focused benchmark with all three models currently available...

All three of the models available in the latest Blender benchmark also ran well on the new Ryzen 9 9950X and 9900X. Once again, the Ryzen 9 9950X leads the pack, clearly outpacing the Core i9-14900K and its previous-gen counterparts. The Ryzen 9 9900X outguns the Core i7-14700K again as well, and nearly catches the 14900K.
Y-Cruncher Multi-Threaded Pi Calculator

The 24-core (8P / 16E) Core i9-14900K looks like a mid-range processor relative to the op-end Ryzen processors with the Y-Cruncher benchmark. The Ryzen 9 9950X and 9900X finish in first and second yet again, outperforming every other desktop processor we've tested.
