New hardware rumors around PlayStation 6 are picking up again. This time the conversation revolves around AMD’s RDNA 5 architecture.

During discussions on NeoGAF, leaker KeplerL2 suggested that Sony may not be planning to use a full retail RDNA 5 GPU inside the PS6. Instead, the console could once again rely on a custom variation built specifically for its needs.

Sony has not confirmed anything. There are no official specifications. What we have is forum chatter backed by a source who has been accurate before. That does not make it fact, but it does make it worth examining.

Not a Full RDNA 5: That Is Not Unusual

Hearing “not full RDNA 5” sounds worse than it actually is. Consoles almost never run untouched PC architectures. The PS5 did not simply drop in RDNA 2 as it existed on desktop GPUs. Sony combined elements from different generations and layered in its own adjustments.

That approach gives console makers control. They define power targets. They define thermal limits. They define cost boundaries. A retail graphics card has to function across hundreds of possible PC builds. A console lives in one fixed box. Different constraints, different priorities.

If PS6 follows the same path, Sony would likely integrate the parts of RDNA 5 that make sense and ignore the ones that do not. That is standard practice. It keeps the chip focused and keeps manufacturing predictable.

Memory Rumors: 30GB of GDDR7

The more striking claim involves memory. The leak mentions up to 30GB of GDDR7.

For comparison, PS5 ships with 16GB of GDDR6. Moving to 30GB and a newer standard would increase bandwidth and headroom. GDDR7 is designed to move data faster, which matters when games stream high resolution textures or handle complex lighting.

Still, big numbers alone do not guarantee smoother gameplay. You can load a system with memory and still hit limits somewhere else. Extra RAM gives developers more breathing space. It does not automatically remove bottlenecks across the board.

There is also the pricing reality. New memory standards cost more early on. A 2027 window would give supply chains time to settle, which makes a larger configuration more realistic. Even so, 30GB would be a bold move.

The Handheld Rumor

The same discussion points to a possible Sony handheld. The figure mentioned is up to 24GB of LPDDR5X memory, with support for PS5 titles.

That does not mean PS5 level performance in your hands. Portable systems operate under tighter power and cooling limits. Lower resolutions and adjusted settings would likely bridge the gap. A dockable design has been mentioned as well, which suggests a flexible role rather than a direct PS5 replacement.

Backward compatibility appears to be part of the broader idea. A shared ecosystem across PS5, PS6, and a handheld would strengthen the platform overall. Technical limitations remain part of the equation, especially in portable hardware.

Why Custom Chips Still Give Companies the Edge

Some ask why console makers do not install a top retail GPU and move on. The answer is simple: consoles are built around balance.

Desktop GPUs assume large power supplies and aggressive cooling. Consoles have stricter limits and fixed budgets. Semi custom silicon removes unnecessary overhead and integrates system level features more tightly.

The goal is not to win PC benchmark charts. The goal is stability, consistency, and a platform developers can rely on.
