Ryzen 3 2200g Power Draw

Because of the Microarchitectural Data Sampling (MDS)[1] vulnerabilities in 2018, computers have a huge performance impact after mitigation. Apple suggests disabling hyper-threading (HT) for full mitigation.[2] My i3-370 (ThinkPad T410i), i5-6200u (ThinkPad L460), and i5-3210M (Mac Mini Late 2012) are all using HT. Maybe that's why they slowdown considerably since 2019.

On the other hand, J3455 is a quad-core processor. It's more responsive than the dual-core and the dual-core-quad-thread processors. I decided to build the next primary desktop with an AMD quad-core processor without simultaneous multithreading (SMT)[3].

Computer Parts

A summarized table of all the parts used to build the computer. More about the case, case fan, and power supply are in another post[4].

Implementation

Assemble

Because Jonsbo C2 is a small Micro-ATX case, I use an SFX PSU to leave more room to others. Although there is an extra 1cm for the CPU fan to breathe, it's still very close to the SFX PSU.

Use an APU and an SFX PSU could help both to breathe cool air from the bottom intake fan.

Both of the AMD fusion controller hubs (FCH)[17] A320 and the MX500 run hot without air circulation. Fortunately, they are closed to the intake fan.

The bottom case fan also improves airflow around FCH and SSD.

The original feet stand is 0.5cm height. I add another 1.6cm rubber feet stand to lift it off the table a little higher. The bottom intake fan may breathe easier now.

Combine with another rubber feet stand to lift the case further off the table.

Unfortunately, the self-drilling screws are too big. It huts the frame of the side panel. I have to cut down or replace it with others.

Ryzen Power Tech Terminology

CPB: Core Performance Boost a.k.a. Turbo Core

Automatically increase processor frequency in 25 MHz steps to improve performance when the average CPU power (ACP) is lower than the thermal design power (TDP). Similar to Intel's Turbo Boost which changes in 100 MHz steps. [18][19]

It's not governed by temperature.

XFR: eXtended Frequency Range

When the CPU cooling is better than the minimum spec, XFR uses the extra thermal headroom to push the average frequency higher and allow it to be sustained for longer for Ryzen X-series using FCH B450/X470[20].

Ready to overdrive Ryzen X-series when CPB is enabled on supported FCH.

PBO: Precision Boost Overdrive

Redefine new Package Power Tracking (PPT: socket power in watts) / Electrical Design Current (EDC: VRM current in amps when VRMs are limited by electrical capacity) / Thermal Design Current (TDC: VRM current in amps when VRMs are limited by temperature) values to replace the default for Ryzen X-series using FCH B450/X470.[21]

It doesn't change the frequency.[22]

cTDP: Configurable Thermal Design Power

Specify the power level of the processor.[23]

AMD Cool'n'Quiet

For desktop processors to decrease frequency and voltage to save power.[24] AMD PowerNow![25] is for laptop processors.

P-States: Performance State

The power-performance states of a processor. It's similar to SpeedStep, PowerNow!, and Cool'n'Quiet. P0 means maximum power and frequency. Pn is less voltage and frequency than P(n–1).[26]

Power Supply Idle Control

For older or cheaper power supply to work with a modern motherboard. The later draws less power than the former's turn-off level. Enable this feature to prevent the PSU to turn off itself when the motherboard goes to sleep.[27]

BIOS Configuration

The requirement is to allow working within the standard specification frequency. There is no need to overclock to prevent generating extra heat.

The location is for A320M-A PRO with BIOS version E7C51AMS.130 on 2019/11/8. It might change in the future update.

Temperature and Power Consumption

My Real-World Experience

I use the Psensor monitoring Tdie, Tctl[33], and GPU in Ubuntu 20.04LTS and a power meter plug for power consumption. The room temperature is 26.5°C.

• 32°C/23W after login and Psensor has been launched.
• Up to 52°C/59W while Chrome is loading 102 tabs.
• 37°C/25W after loading.
• 37 ~ 38°C/30 ~ 38W while checking emails and reading static pages.
• 37 ~ 38°C/31 ~ 36W while watching a YouTube video at 720p.
• 34°C/25W after closing Chrome for a while.

Here is the performance and power consumption summarize table comparing to others.

Reports from Others

1. "AMD Ryzen 3 2200G review – Power Consumption"[34] shows about 43 ~ 92W for benchmarking. Up to 101W for gaming.

Concerns

Temperature

1. I choose to manage the system temperature within 50°C. It is because Seagate suggests the operating temperature range for a hard drive is between 5 ~ 50°C.[35]
2. I use Ryzen on coding, testing, VirtualBox, web surfing, and graphics. The processor won't be busy continuously for long.

Processor

1. A Python and PHP benchmark report shows that Pentium G4400 (the 6th generation SkyLake architecture) is faster than Ryzen 3 2200G.[36] Wondering if the G4400 has the latest firmware mitigation.
2. AMD Ryzen has a better security design and fewer incidents.[37] The Intel processor got a 16% performance hit while AMD Ryzen is 3% after the default mitigation for Spectre/Meltdown/L1TF/MDS.[38]
