Recently I upgraded CPU, MOBO and RAM in my rig. I figured out it might be a good idea to compare upgraded system to old config. Especially, because I did not yet see a Ryzen 3000 review which directly compares new Ryzen CPUs to X79 antiques.

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.

AMD system:

  • Ryzen 9 3900X
  • ASRock X570 Taichi (BIOS 1.80 AGESA ABB)
  • GSkill F4-3200C14D-32GTZKW (2x16GB @ 3733MHz 16-16-16-32 1T GDM On)

Intel system:

  • Core i7-4930K
  • Asus X79-Deluxe (BIOS 4805)
  • GSkill F3-17000CL9Q-16GBZH (4x4GB @ 2133MHz 9-11-10-28 1T)

Shared components:

  • Samsung EVO 850 500GB
  • Palit Gamerock Premium GTX1080
  • Noctua NH-D15S
  • Corsair AX860

Used software versions:

Software Version
Windows 10 1903
nVidia drivers 431.60
AMD chipset drivers
Cinebench R15 R15 (Build RC184115DEMO)
Cinebench R20 R20.060 (Build RBBENCHMARK281795)
CPU-Z 1.89.1.x64
CPU-Z Benchmark 17.01.64
SuperPi mod1.5 XS
3D Mark Time Spy v1.1
Shadow of the Tomb Raider v1.0 build 294.0_64
Metro Last Light Redux Redux Benchmark v3.00 x64

For both systems Windows 10 1903 was used, however there was probably like a month between running tests on Intel platform and AMD platform, therefore Windows had more patches applied when AMD test was run. For AMD system “Ryzen high performance” power plan was used (the one which comes from AMD chipset drivers) and for Intel the default Windows one was picked.

4930K was tested at default clocks (3.9 GHz) as well as overclocked to 4.4 GHz. 4.4 GHz seems to be average OC, which most of 4930K can reach. 3900X was not overclocked at all. PBO was set to Auto during the runs, I don’t really see a point in overclocking Ryzen 3000 series CPUs due to the fact how well XFR2 works.

Tests Results

Cinebench R15

Cinebench R20

As expected 3900X slaughters 4930K in multi core runs, after all it has twice the amount of cores. It also beats the 4930K in single core performance in this bench, which again is not a suprise if you think about it. IPC of the CPUs increased quite a bit since X79 was released and 3900X actually runs around 4.5 GHz when only single core is loaded.


CPU-Z benchmark shows the same story as Cinebench R15 and R20. Ryzen 9 3900X is the clear winner.

SuperPi 32M

SuperPi was always Intel domain, but 3900X manages to beat 4930K at default clocks, when OCed to 4.4 GHz Intel CPU is still faster.

Time Spy

Time Spy is another win for AMD. I did not expect such big differences in overall score between different CPUs to be honest.

Shadow of the Tomb Raider

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

Resolution 1920x1080
API DirectX 12
Vsync Off
Anti-Aliasing TAA
Preset High

Metro Last Light

Settings used for Metro Last Light Redux:

Resolution 1920x1080
Quality High
Texture filtering AF 4X
Motion blur Off
Tesselation Off
Vsync Off
Advanced PhysX Off


Some comparison charts:

3900X vs 4930K @ 3.9 GHz

3900X vs 4930K @ 4.4 GHz

Looking at those we can see that 3900X is a huge improvement for every application which can use multiple cores (hardly a surprise :-)). Single core performance is also higher on 3900X, even when compared to overclocked 4930K. Gaming wise the performance gain is around 10% although only in 1080p. With higher resolutions performance boost will definitely not be that big (if any). Generally speaking I am quite happy with the upgrade.
