PS6 Reportedly Won’t Feature Full RDNA 5 Architecture
It looks like Sony may choose a mixed hardware approach for its next console. While many expect PlayStation 6 to fully embrace AMD’s upcoming RDNA 5 architecture, a new rumor suggests things may not be that simple.
According to well-known leaker KeplerL2, the PS6 will not use a pure RDNA 5 design. Instead, it could once again use a mix of technologies rather than relying on a single architecture.
PS6 Will Not Feature a Fully RDNA 5 Architecture
“PS5 is just RDNA1 + Ray tracing, there is no magic Mark Cerny customizations,” the leaker wrote during a discussion on the NeoGAF forum.
“And btw PS6 isn’t full RDNA5 either,” KeplerL2 added, suggesting that Sony will once again adopt a mixed approach for its upcoming platform.
This would mean that, just like PlayStation 5, the next-generation console could combine elements from different AMD architectures rather than relying entirely on a single one.
The same source previously reported that both PS6 and a new PlayStation portable device will feature notable improvements in terms of memory. The next-generation console is said to be equipped with 30GB of GDDR7 RAM.
KeplerL2 also claims that the memory modules in PlayStation 6 will be configured to ensure a bandwidth of well over 640 GB per second, a value more than 11% higher than that of PS5 Pro.
It will also be interesting to see how the ongoing memory supply issues could affect the final price of the console. Sony currently has a plan to avoid price increases at least until the next fiscal year — but it remains to be seen whether the situation will stabilize by then.
In other news, former PlayStation CEO Shawn Layden discussed the possibility of the PS6 launching without a disc drive, stating that this would be challenging for Sony due to various market factors.

AMD’s RDNA 2 and 3 architectures into the Pro’s GPU, a combination referred to as RDNA 2.x, but had to be selective to ensure Pro games were still compatible with the base PS5 (which runs on RDNA 2.0). Cerny gives examples of RDNA 3 usage with the Pro’s boosted primitive processing capabilities.

PS6
8x Zen 6C + 2x Zen 6 LP cores
RDNA 5 with AI/RT acceleration (Project Amethyst)
52-54 CUs
34-40 TFLOPs
PSSR 2
3x times as powerful as the standard PS5 in terms of rasterization performance, and about 2x as powerful as the PS5 Pro
Saying its not RDNA 5 is a bit of a fetch. PS5 isnt even RDNA 1 or 2. Its Custom RDNA. And so is the PRO.
PS5 was based on RDNA 2 with custom features. It didnt need to be full RDNA 2. It wasn’t needed. PS6 same story it is and isnt RDNA 5. Also it could have more on top. We don’t know until we get announcement its all speculation. But going on history and Cerny it will have a very similar pattern.
