AMD's rumored Magnus APU to power next-gen Xbox, PlayStation 6: 11-core Zen 6 CPU, huge GPU

AMD is reportedly cooking up a new semi-custom APU codenamed Magnus, which will be used inside of the next-gen Xbox and/or PlayStation 6 consoles.

In a new video from leaker Moore's Law is Dead, we're hearing some information on a new mega APU dubbed "Magnus" that sports a huge 264mm2 graphics die on a 384-bit memory bus, and a 144m2 SoC die that's connected through a bridge die that connects the graphics die to the 11-core CPU die. The 11-core CPU die sounds weird (11 cores, right?!) which is split between 3 x Zen 6 cores and 8 x Zen 6c cores.

The purported new Magnus APU is a semi-custom chip made by AMD that should be for Microsoft's next-generation Xbox console, but leaker MLID says it could be used in the upcoming PlayStation 6 console. Another leaker chimed in to this post, Kepler_L2, noting that "that is probably the next-gen Xbox, the codenames that AMD uses for PlayStation SoCs are from Shakespeare characters".

As for the Magnus APU and its huge 264mm2 graphics die on a 384-bit memory bus, that's a wider memory bus than any current generation console, with the widest memory bus inside of a console being the 320-bit memory bus on the Xbox Series X console.

We should expect more details on AMD's purported Magnus APU in the months ahead, with the next-gen consoles not hitting the market until 2027-2028.
