An official Linux kernel patch has given credibility to the previously leaked specs of the rumored PS6 handheld.
Back in August, 2025, leaked PS6 handheld specs shared by hardware insider Moore’s Law Is Dead (MLID) revealed the unannounced portable device will feature a 6-core CPU composed of four primary Zen 6 cores and two additional Zen 6 Low Power cores. It was mentioned that the latter will primarily handle OS and background tasks, though there was no official information from AMD regarding the existence of Zen 6 Low Power cores at the time. However, new details have surfaced with the arrival of a new official Linux kernel patch (via JohnBarry_Dost on Reddit).
The aforementioned details from the recent official Linux kernel patch can be seen below.
“This series extends the x86 topology cpu_type classification to support a Low Power core type, in addition to the existing Performance and Efficiency types.
AMD heterogeneous parts report the core type via CPUID Fn0x80000026EBX[31:28] (Extended CPU Topology, Core Type). Value 2 identifies a low-power core designed for minimal power consumption during background or idle workloads.”
The mention of a “low-power core designed for minimal power consumption during background or idle workloads” essentially confirms the existence of Zen 6 Low Power cores, giving credibility to the PS6 handheld specs previously leaked by MLID. The portable device’s CPU configuration is said to be paired with a 192-bit LPDDR5X-8533 memory controller supporting up to 48 GB of RAM. On the graphics side, the device is said to house 16 RDNA 5 compute units, clocked at approximately 1.20 GHz in handheld mode and up to 1.65 GHz when docked. Performance estimates suggest rasterization will reach around 55 to 75 percent of a PlayStation 5 in docked mode, with ray tracing capabilities projected to surpass the PS5 by a significant margin.
Other listed features include backward compatibility with PlayStation 4 and PlayStation 5 titles, a microSD slot, M.2 SSD storage expansion, haptic vibration, dual microphones, and a touchscreen.
