iGPU Performance, Power Consumption
Before moving onto power consumption here is a quick look at iGPU performance. Basically. even at 720p you're going to have a hard time playing anything on the Pentium G5400 without a discrete graphics card. However, the 2200G is very respectable and when overclocked can beat the RX 550 in some titles. So if you're going to be making do without a graphics card for any period of time, the Ryzen 3 2200G is a must.
Remember the Pentium G5400 is a dual-core while the Ryzen 3 2200G is a quad-core, so you can expect the faster more powerful quad-core to consume more power. Looking at the Far Cry 5 results, we see that is indeed the case. Here the 2200G pushed total system consumption 29% higher but remember it was 32% faster so in terms of performance per watt the Ryzen 3 CPU actually does better.
The G5400 looks more efficient in Ashes of the Singularity though, in which the 2200G consumed 28% more but was only 18% faster. Not exactly a noteworthy margin but it does make the Ryzen 3 CPU less efficient here.
Finally we have the Corona benchmark and here the G5400 system consumed 43% less power while it was 32% slower, so again slightly better efficiency from the Pentium CPU but overall it was still much slower.
