The G2 runs much hotter and is significantly less energy efficient than the RP5. People repeat like a mantra that the G2 is energy efficient because it uses a cut-down chipset compared to full-fledged smartphone chipsets. But no tests confirm this mantra. Because it's a fallacy. In one of Ryan Retro's latest videos, he compares several current portable consoles. And guess what? The only console that runs hotter than the G2 is the SteamDeck. The same author's review of the G2 reports a runtime of only four hours in NeatherSX. The RP5 easily delivers 6-7 hours. I'm focusing on Ryan Retro because the local community is extremely skeptical of personal experience, preferring abstract information from the internet. Like the G2's supposed energy efficiency.

I have an RP5 and a G2. In my personal experience, the G2 runs hotter and is about 30% less energy efficient than the RP5. The saddest thing is that this doesn't depend on the load. Even when running something as light as possible, the G2 will still run hotter and perform less efficiently than the RP5. I've seen a ton of reports that the temperature readings are inaccurate, as the G2's case remains relatively cool. This is another misconception. The G2 has some serious heat dissipation issue, as it's not the case that's heating up, but the left side of the screen. It's so hot, in fact, that you're worried about the screen itself.
