Introduction

I’ve covered my self-hosting setup in a previous post. It has been a couple of months and the setup has mostly been fine. Sure, the power usage was pretty big under load, and yes, my internet did cut out every time I turned the VM on with all the services starting, but other than that, it has been rock-solid.

However, I soon realized that in most situations, the 12 CPU cores is a bit overkill. Performance was fantastic, but due to the case and the cooling solution that I’m using, the fans did have to ramp up to cool the CPU down. Due to the ongoing GPU drought driven by yet another cryptocurrency bubble, it also felt a bit wasteful to use an AMD RX 560 just to drive two 1080p monitors.

It just so happened that around this time, AMD released the Ryzen 5000 G-series APU-s to retail. Yes, you could buy the 4000 series “OEM-only” APU-s from certain online retailers as well, but with this release, it’s 100% official. The release date rolled around, and the reviews were good. A day later, the CPU was also listed at a local reseller and was actually in stock. After checking the street price for a used Ryzen 9 3900X and the Radeon RX 560, I decided to go for it, as it would be very close to a free “upgrade”.

Prep work

Before performing the purchase, I confirmed that the motherboard that I use (Gigabyte B450 I AORUS PRO WIFI) supports this CPU after a BIOS upgrade. B450 chipset lives in a bit of a gray area where the CPU support is determined by the motherboard manufacturer. No updates? No CPU support for you.

From my previous BIOS updating experiences, I remember that this particular motherboard had some buggy BIOS implementations. I ran into two issues:

  • PC would get stuck on POST if you reboot. It’s annoying when making changes to UEFI settings, but with my use case this is not that big of a deal.
  • If you remove a boot option, then it is impossible to get it back. Seriously, even a CMOS reset did not help with this one.

This time around, I decided to update the versions one by one to follow the happy path and not run into other types of issues. The bug did resurface right after the first version that I tried, so that was a bit disappointing.

Now would be the perfect time for a surprise power outage or a cat intervention.

Once I was all up-to-date, I carefully removed the old CPU and plugged in the new one.

Hold on, why would you intentionally downgrade your CPU?

It all came down to “use the right tool for the job”. The Ryzen 9 3900X is a good CPU, no doubts about that, but during my work, I kept an eye on my CPU usage quite often and found that even in the worst-case scenarios, such as IntelliJ IDEA performing indexing, I wasn’t using the CPU to the full extent. It’s great for those scenarios, but I wasn’t hitting them as often as I would have thought.

It also did not help that the CPU did not have an integrated GPU. When all you have to run is a basic desktop setup with 60Hz 1080p monitors, having a dedicated GPU to run them sounds so wasteful. This increased the power use of the whole setup and the GPU could be utilized better elsewhere.

The Ryzen 7 5700G is a downgrade in multi-core performance, mainly due to 4 fewer cores and only 25% of the L3 cache, but according to various reviews and benchmarks, you could actually expect a small single-core performance uplift. Nothing groundbreaking, but good enough for my use case.

Power usage

Because I don’t change my CPU-s too often, I thought I’d take the time to run some benchmarks and measure the power usage of the whole setup. This includes everything: the PC (with two spinning hard drives), standing desk, two 1080p monitors and peripherals.

Please note that these benchmarks are not very scientific and are simply my observations of the change you can expect when performing a switch like this on your own setup. I did my best to make sure that the running conditions are as close as possible by stopping the service VM, waiting until the background CPU usage was normal, running the memory at the same spec etc.

AMD Ryzen 9 3900X + Radeon RX 560

  • Idle, sitting on desktop: ~139W
  • Full synthetic CPU load using stress: ~253W

AMD Ryzen 7 5700G + integrated Vega 8 GPU

  • Idle, sitting on desktop: ~99W (generally between 85-100W)
  • Full synthetic CPU load using stress: ~166W

As expected, the change of the CPU and removal of the dedicated GPU results in a big drop when it comes to the power usage of the whole workstation setup. To go even lower, I’d have to switch out the core of the PC to something like the ASRock Deskmini X300 and replace the hard drives with two big SSD-s. I’d go for that as soon as bulk SSD storage became a viable option. Unfortunately, this is not the case, yet.

Performance

Reputable review sites, such as AnandTech, have already done a lot of benchmarks with better testing methodologies, so I instead went ahead and tested out something that I do quite often at work: running tests in poorly written Java projects!

For this, I have two Java projects that have their own test suites. Project A has 900 or so tests, which are mainly parallel in nature. Project B has 2000+ tests, where a good number of them are dependent on a single thread to do all the work.

To run the tests, I just call the “Run all tests” function in IntelliJ and let it do the work of running the tests and measuring the elapsed time. And as mentioned before: this is not scientific, there are probably some errors in here, but the actions performed here are in my opinion a pretty good reflection of day-to-day work, and that’s what matters the most to me. Tests were run twice with a short break between the test runs to let the CPU cool down a bit.

Project A: AMD Ryzen 9 3900X

Test run 1: 10.396s.

Test run 2: 10.494s.

Project A: AMD Ryzen 7 5700G

Test run 1: 15.561s.

Test run 2: 15.690s.

Project B: AMD Ryzen 9 3900X

Test run 2: 365s.

Project B: AMD Ryzen 7 5700G

Test run 1: 471s.

Test run 2: 480s.

The performance hit was somewhat expected for project A due to the parallel nature of the tests. However, for project B I expected better results than that due to the alleged improvements in single-thread CPU performance.

The Linux experience

I expected the APU to work as expected, with perhaps some small issues popping up here and there. I’m currently running Fedora 34 with all the latest updates installed and the kernel version at 5.13.6, which should be the best option when trying to get new hardware working on Linux.

The CPU portion of the APU is working relatively well for a CPU that was released just a couple of days ago. I have noticed that for some reason this CPU is constantly clocked at around 4.2GHz on all cores at all times, even if there isn’t too much going on in the system. sensors, the program I use to monitor system temperatures, is also having a small hiccup, as I cannot see the CPU temperatures at all, only the integrated GPU temperatures show up even after running sensors-detect.

vddnb:       999.00 mV

power1:        6.00 mW

The GPU seems to be a bit rough around the corners. I’m using the GNOME desktop environment, which means that I’ve learned to endure laggy user interfaces. I default to using Wayland, but I sometimes also use Xorg for those situations where the application I’m trying to run does not work properly under Wayland (looking at you, Slack and your screen sharing functionality…).

The integrated Vega 8 graphics are almost as fast as the dedicated RX 560 GPU under normal light desktop workloads. Once you run something very heavy, like Furmark, the GPU performance tanks and the desktop becomes almost unusable. This is not the case when running some WebGL workloads though, so it could be an isolated case.

The most serious issue I’ve managed to find is that Firefox has some issues with this GPU once you put enough load on the GPU. You may start to notice flickering and UI elements blinking when moving around. A good test case for this is to run Netdata in live mode and have a 1080p Youtube video in another window. I haven’t seen anything like that since running the Nvidia GT 710 with Nouveau drivers under Fedora 34. At least it does not crash the browser or the Wayland session, so it’s not a complete disaster. Still, pretty annoying, so I hope this gets resolved eventually. If I had to guess: the issue is probably related to the Webrender implementation that makes use of the GPU to speed up the browsing experience.

Closing thoughts

Overall, I’m happy that the APU actually works. I’ve had a couple of bad experiences in the past where the Ryzen 3 2200G had stability issues and had to be replaced, so this experience is already a step up from that. The PC runs cooler and quieter, the desktop experience is good enough for me and the CPU performance is acceptable.

I’m sure that the issues that I’ve had with this APU under Linux will be fixed eventually. Each kernel update usually brings lots of improvements to new hardware and I’m sure that this APU is no exception.

As for the BIOS issues, I’m happy that AMD and Gigabyte opted to support the B450 chipset well into 2021, but I’m sure that this choice has come at the cost of QA. If I had to choose between buggy support and having to buy a new motherboard for my new, shiny CPU, then I’d still pick the first one.

Update (2021-08-18)

I’ve had this CPU for a while now, and there have been a couple of kernel updates in the meantime. Here are my notes.

The idle power usage has recently been in between 65-70W for the whole setup. I’ve measured the desktop itself to take up 38W of that.

Although my motherboard does not seem to expose the cTDP option or have ECO mode available, I still managed to limit my TDP to 45W using this trick that /u/The-Stilt mentioned over at Reddit:

The potential lack of the ECO-mode does not prevent you from using it, 
since it is nothing but a preset of PPT/TDC/EDC settings.

Eco-Mode (95W): PPT = 128W, TDC = 80A, EDC = 125A

Eco-Mode (65W): PPT = 88W, TDC = 60A, EDC = 90A

Eco-Mode (45W): PPT = 61W, TDC = 45A, EDC = 65A

This had a great effect on the full load of the system: 3.8GHz all-core while the whole setup consumed 113W.

Precision Boost Overdrive settings that should result in a nice efficiency win. Target = 45W.

Update (2021-08-20)

Quick update on the GPU situation: Firefox seems to be fine now, I could not get the flickering to occur again even under worst case scenarios.

Here are the outputs for a couple of commands that I could think of.
