Details about Xbox’s next-generation processor surfaced on the YouTube channel Moore’s Law is Dead and concern an APU codenamed “Magnus” that AMD is reportedly building for Microsoft’s upcoming console.
According to the leak, the Magnus APU is currently in the design stage. Manufacturing is scheduled to begin in 2027, with the console’s launch expected in the second half of the same year.
The new chip is said to include 68 RDNA 5 compute units (CUs) and at least 24 MB of L2 cache. The CPU portion will combine eight Zen 6C cores with three Zen 6 cores. The memory controller reportedly supports up to 48 GB of RAM on a 192-bit bus, although the final amount of system memory in the retail console could be lower.
The source estimates the APU’s power draw at roughly 250–350 W, but those numbers remain provisional.
When compared to rumored details about the upcoming PS6, performance will depend heavily on clock speeds, yet Moore’s Law is Dead claims the new Xbox could be roughly one-third faster than Sony’s system. That performance advantage will likely come with a higher price for Microsoft’s device.
Earlier, the same source noted that neither the Xbox nor the PS6 is expected to match the performance level of RTX 5090 or 5080 GPUs.
