PS6 and handheld rumored to feature full PS4 and PS5 backward compatibility

A new PlayStation 6 leak is pointing to one of Sony's most consumer-friendly moves yet, and it could redefine how the next-gen ecosystem works.

According to a leak shared by Moore's Law Is Dead, both the PlayStation 6 and its rumored handheld companion will support full backward compatibility with PlayStation 4 and PlayStation 5 titles. The information reportedly comes from an internal AMD presentation slide outlining Sony's next-gen plans built on the RDNA 5 architecture.

If accurate, this would give players access to a massive library of existing games at launch, something that has increasingly become a key expectation for modern consoles. Digging into the details, the leak highlights several technical pillars behind the PS6 platform. These include AI-driven upscaling features like Super Resolution, improved ray tracing with backward compatibility for PS5 titles, and dedicated engineering workstreams focused on ensuring seamless compatibility across generations.

There's also a focus on efficiency, with low-power media playback and specific optimizations to meet EU energy regulations. Notably, the PS6 handheld isn't being treated as a separate device; it's described as part of the same ecosystem, effectively functioning as a portable PS6. Even more interesting is the cost: the handheld's APU is estimated to cost Sony just $46.8 to produce, significantly cheaper than the PS5's chip, while still reportedly outperforming it.

If this leak holds up, Sony could be preparing a flexible, unified next-gen platform that spans both home and portable gaming, without leaving your existing library behind. Previous rumros indicate Sony's upcoming handheld will be more powerful than the Xbox Series S and the Nintendo Switch 2. More on that below.
