According to a new report, Switch games can use 3 out of 4 CPU cores and 3 out of 4 GB of RAM. Which means that 25% of the system resources (1 core + 1 GB of RAM) is reserved for the operating system and background tasks.

Over the weekend we spoke to a Switch indie developer, who confirmed the recent Switch hardware specs, and revealed to us who much of the system resources games can actually use. We’ll have the full interview up later this week.

The Wii U had 2 GB of DDR3 RAM, but half of that was reserved for the OS — the same amount that the Switch OS uses.

By comparison, the Xbox One has 8 GB of RAM, where 3 GB is reserved for the operating system. The PS4 reserves about 2 GB for the OS.

Both the Xbox One and PS4 are reported to use 2 cores for the OS as well (an update last year made the 7th core available for PS4 games, but only under certain circumstances).

Comparing the three systems and their RAM use, it would looks like this:

Switch: 4 GB RAM – 3GB for games

Xbox One: 8 GB RAM – 5 GB for games

PS4: 8 GB RAM – 6 GB for games

Overall, it seems that the Switch is roughly on on par with the other consoles in this regard, as all three use about 25% of the system resources for the OS (the Xbox One a bit more).
