The PS5 Power Saver Mode limits the console’s maximum CPU utilization to 4 cores in order to match the PlayStation handheld specs.
In his latest video, hardware insider and content creator Moore’s Law Is Dead (MLID) has claimed that the PS5 Power Saver Mode restricts the console’s CPU usage from 8 cores and 16 threads to just 4 cores and 8 threads to match the PlayStation handheld specs. “[These are] the exact specs of the PlayStation handheld,” he said. “Four [cores], so eight threads for the game.”
According to the insider, this limitation mirrors the expected CPU configuration of the console maker’s upcoming handheld device. Rather than being a simple power-saving feature, the mode allegedly serves as a testing ground or compatibility layer for running PS5 titles on less powerful hardware. He also pointed to earlier guidance given to developers. In late 2025, Sony Interactive Entertainment reportedly advised studios to ensure their games could run on as few as eight threads. Considering the PS5 normally operates with 16 threads, this guidance strongly implies preparation for a system with reduced CPU resources. “What they’re saying is they will soon have a PlayStation that uses a quad core to run games, not eight cores,” he explained.
Another key piece of evidence comes from Sony Interactive Entertainment’s handling of its Software Development Kits (SDKs). The insider stated that Power Saver Mode support has been implemented across all PS5 SDK versions, even going back to the original 1.0 release from 2020, something that didn’t happen in the case of the PS5 Pro. According to him, this level of backward integration means that the console maker is “really invested in developers supporting powers saver mode and [it wants the feature] to be in every SDK so that it is pretty much like flipping a switch for a developer to support it.”
MLID challenged the idea that limiting cores is an effective way to save energy, arguing that reducing clock speeds across more cores is typically more efficient than forcing fewer cores to work harder. He also claimed that the Power Saver Mode is being handled almost like a separate platform, even receiving its own asset and texture packaging under newer delivery systems, which would only be plausible if it represents a distinct hardware target.
