Introduction & Test System
AMD Ryzen 5 2400G Review: Zen, Meet Vega went in-depth on the Raven Ridge architecture and explored the flagship processor's performance. Today, we're taking a closer look at the power consumption, clock rates, and temperatures of AMD's Ryzen 5 2400G and Ryzen 3 2200G. We're also pitting the stock thermal solution against our high-end chiller in order to find a temperature-independent power limit for the Ryzen 5 2400G.
It is also interesting that AMD uses heat-conducting paste instead of solder between its Raven Ridge dies and heat spreaders. However, with an average power dissipation of less than 100W, this cost-cutting measure is probably tolerable for everyday operation. Of course, we also ran a series of more demanding workloads to tax both processors. It comes as little surprise that we figured out how to get the 2400G to throttle. We weren't expecting, however, to get its Radeon Vega Graphics engine stuck that way.
We’re using the same hardware for today's testing as what you saw yesterday: AMD's Ryzen 5 2400G and Ryzen 3 2200G, the Gigabyte AB350N Gaming WiFi with two 8GB G.Skill FlareX DDR4-3200 modules, and AMD’s Wraith Stealth cooler (an OEM part from AVC’s massive portfolio sporting an AMD label). Four screws hold the thermal solution in place, giving us a much more secure mounting mechanism than Intel's push-pin system.
In order to establish the limits of AMD's Raven Ridge-based processors, we need to push them as far as they can go. That's where Alphacool's powerful Eiszeit 2000 compression chiller comes into play. We combine it with the Alphacool Eisblock XPX, replacing AMD's Wraith Stealth heat sink. Motherboard components are cooled by 22°C air from a large fan blowing across them.
But before we dig into our findings, let's quickly recap the hardware used to test, the equipment in our lab responsible for our accurate measurements, and some of the software we run to monitor sensors:

The prices you chose to use here are bogus - the $99 and $169 MSRP are what they're actually going for.Reply

The prices from Amazon or NewEgg (or whatever) are usually inaccurate. I think Tom's should provide us with the MSRP and the internet price. That way, if the internet price is malfunctioning and showing a +50% markup, at least we know what it's SUPPOSED to sell for.
edit: minor fix
When I wrote this review, we had only the official MSRP from AMD. The availability in Germany looks ok and the prices in EUR with VAT are lower :)Reply
The prices (provided via direct link to Amazon.com) are now correct. Unfortunately, they are all sold out...lol.Reply
Best solution to put these in would be your stand alone calculators.Reply
These seem to be very efficient for the CPU and GPU performance they deliver. Nifty more options for budget PC's.Reply
I am left wondering if the 14nm process AMD is using, is having issues scaling to higher frequencies as it appears you keep Zen and Vega at lower clocks and they are very efficient.
I really like the new power management and it is finally nothing else as efficiency-orientated mobile technology for the desktop.Reply
Maybe the 2400G is so smart and powerful, that when it reaches critical computational capacity, it evolves to become sentient, and thus unruly. Only after it is rebooted, to have the sentience removed, will the system cease its rebellious behavior. (Actually, I don't think this..but it's all I've got).Reply
For the 2400G, bundling the better Wraith Spire could probably avoid the throttling bouncing around by preventing it from hitting the thermal limits under the more taxing loads.Reply
Eventually though they're going to have to find out what's causing it to get stuck in that loop.
Obviously 2400G wants to protect itself from some poor saps trying to use it for cryptocurrency mining.Reply
