What Just Happened?
Phoronix spotted a Linux kernel patch series submitted by AMD engineer Vishal Badole that introduces a third CPU core type for AMD chips. The patches extend Linux’s x86 topology code — which already handles Performance and Efficiency cores — to support this new Low Power classification.
According to AMD’s patch notes:
“A low-power core designed for minimal power consumption during background or idle workloads.”
Why This Matters for PC Gamers
1. Better Battery Life in Handheld PCs
This patch is strong evidence that AMD is building dedicated low-power cores for future chips. Devices like the ASUS ROG Ally, Lenovo Legion Go, and potentially the next PlayStation Portable or Steam Deck successor could benefit from dramatically better battery life during light tasks.
2. Smarter Power Management
The Low Power core type is distinct from regular Efficiency cores. These are ultra-low-power cores meant for background app updates, syncing in standby, lightweight music playback, and system idle states.
3. Linux Gaming Ready
The patches ensure Linux properly recognizes these new cores — important as more gamers move to SteamOS and Linux-based handhelds.
FAQ
Will the low-power cores affect gaming performance?
No. These cores are designed for background and idle workloads only.
When will we see AMD chips with low-power cores?
Real hardware likely arrives with Zen 6-based Ryzen processors, expected in late 2026 or early 2027.
Is this related to the PS6 handheld rumor?
Moore’s Law is Dead previously claimed Sony’s handheld PS6 would include AMD Zen 6 LP cores. These patches add credibility.
Will desktop Ryzen CPUs have low-power cores?
Probably not. Expect these primarily in mobile APUs, handheld devices, and console chips.
Final Verdict
AMD’s Low Power core is a smart move for the handheld gaming era. As Steam Deck, ROG Ally, and rumored PS6 handheld compete, battery efficiency is everything.
