I managed to grab 5950X for a decent price, so I decided to upgrade my CPU. Comparison between my old and new CPU can be found here.

Test Setup

Disclaimer: Please keep in mind that I am not a professional reviewer nor I aspire to be one. Those are just the the tests I run for my own curiosity. Testing methodology is most likely flawed, especially when it comes to gaming benchmarks. I do not have enough experience to chose appropriate graphics settings.

Hardware configuration:

  • ASRock X570 Taichi (BIOS 5.00 AGESA 1.2.0.7)
  • GSkill F4-3200C14D-32GTZKW (2x16GB @ 3733MHz 16-16-16-32 1T GDM On)
  • PowerColor 7900XTX Red Devil
  • Plextor M5 Pro 256GB
  • Noctua NH-D15S
  • Seasonic Vertex GX-1000 1000W Gold

Used software versions:

Software Version
Windows 10 22H2
AMD GPU drivers 23.7.2
AMD chipset drivers 5.05.16.529
Cinebench R15 R15 (Build RC184115DEMO)
Cinebench R20 R20.060 (Build RBBENCHMARK281795)
CPU-Z 2.06.1.x64
CPU-Z Benchmark 17.01.64
3D Mark Time Spy v1.2
3D Mark CPU Profile v1.1
Shadow of the Tomb Raider v1.0 build 492.0_64
Metro Exodus Enhanced Benchmark v1.0.0.9 x64

Tests Results

The most important part of this post!

Cinebench R15

Cinebench R20

3DMark CPU Profile

We can see a solid bump in performance, in both single and multi-threaded benchmarks. Gains in range of 20% to 40% are nothing to sneeze at.

Time Spy

Time Spy shows smaller gains than previous benchmarks, but this is graphics benchmark after all. Still 15% gain in CPU score is worth noting.

Shadow of the Tomb Raider

Settings used for Shadow of the Tomb Raider (integrated benchmark):

Resolution 2560x1440
API DirectX 12
Vsync Off
Anti-Aliasing TAA
Preset High

Metro Last Light

Settings used for Metro Exodus Enhanced (integrated benchmark):

Resolution 2560x1440
Preset High
Shading Quality High
Ray Tracing Normal
NVIDIA DLSS Off
Reflections Hybrid
Variable Rate Shading 4x
Hairworks Off
Advanced PhysX Off
Tesselation Full

For gaming benchmarks I chose settings where system was limited by CPU mostly. 1440p and high settings in selected games is really nothing for 7900 XTX. In normal scenario every sane user will max graphics settings at 1440p with such GPU, differences between CPUs will be then smaller for sure.

Conclusion

5950X vs 3900X

One thing to note is that the results for 3900X are slightly lower than results presented in my previous test: Ryzen 9 3900X vs Core i7-4930K. I would attribute it to the fact that early Taichi X570 BIOSes had broken power usage readout, which resulted in CPU boosting bit higher than expected. This is not a big deal as the differences are really marginal.

Obvious conclusion is that 5950X is faster than 3900X. No surprises here, 4 more cores + newer arch do the job. Was it worth upgrading? Well, it is hard to say. I mainly jumped the 5950X ship, because I was able to get it cheaply plus I was kinda fed up with my CPU running 24/7 with LLC set to 1 (see: Strange issue with my 3900X).

Off to tweak memory on new CPU, so far, I only tried same RAM/Bus clocks as on my 3900X (although those worked without any issue)!
