Athlon 3000G Overclocking: Is It Worth It?

Benchmark Results – Synthetic GPU Tests

Unigine Superposition (720p Low)

Superposition is Unigine’s latest benchmark and tech demo for their game engine. 720p Low is a sensible preset for a low-end APU. FPS numbers aren’t directly meaningful for synthetic benchmarks, but 720p Low was in the 20-30fps region. This shows it may be fairly representative of a more stressful game.

CPU OC did almost nothing, and both iGPU and memory OC showed solid gains. Most of the gains here came from pushing iGPU speed.

Unigine Superposition (8K Optimised)

For fun, a totally inappropriate preset. A more serious purpose is to see how massive memory requirements were handled. Forcing the tiny Vega 3 to render at 8K resulted in a sub-2-fps slideshow. This is hopefully not representative of the kind of gaming load anyone would run on this chip.

Interestingly, pushing the resolution up actually reduced the reliance on memory. Superposition at 8K is dependent mainly on iGPU speed.

3DMark Time Spy

A DirectX 12 benchmark for faster gaming PCs, Time Spy allows comparison with faster setups. The graphics tests got around 3fps, so this isn’t realistic.

3DMark Night Raid

Night Raid is a DirectX 12 benchmark aimed at laptops and integrated graphics.

3DMark Sky Diver

Sky Diver is an older DirectX 11 benchmark aimed at laptops and integrated graphics.

All of the 3DMark benchmarks we ran were similar – most performance by far came from iGPU clock, but memory also helped a lot especially once iGPU has been pushed. Memory performance feeds the iGPU, so the faster the iGPU the more the memory matters.

  1. I’m amazed by the fact that you got to DDR4 3800 CAS 18 on this combination of RAM CPU and Motherboard. I wonder if even faster RAM (if even possible) would make it go further.
    I’m interested in this chip not because I need a cheap PC, but cause I want a fun overclocking rig outside of my main PC.
    Although it wouldn’t make much sense monetarily, I was thinking on paring it with a mid range board, mostly for the SOC VRMs which might not be as stable as a 2 phase and would probably get quickly overloaded with higher power targets, also cause I’d like to use it with a Zen 3 APU down the line.

    • I managed DDR4-4000 CL18 using an MSI B450I GAMING PLUS AC with Crucial Ballistix Sport rated for 3000 CL15 (Micron “E-die”). Normally older gen AMD CPUs top out around 3600 with good memory so I’d be (even more) surprised if it has more in it than that.

      It’s a really fun CPU for overclocking and tweaking, but check compatibility carefully – sadly most X570 and B550 boards choose not to support the 3000G. This seems to be because it uses the older Zen 1 cores and is therefore classed as a “first generation” product – despite being numbered in the 3000 series!

      Unfortunately this creates a bit of a quandary when it comes to the upgrade path. I’ve written a bit about the compatibility situation at https://play3r.net/news/articles/b450-zen-3-compatibility-amd-bow-to-community-pressure/ but generally, a B450/X470 board fully supporting the 3000G has a lot of caveats when it comes to future processors. Hopefully that doesn’t put you off though, because it really is a fun chip to play around with.
