On October 10th, the source Moore's Law is Dead (MLID) released a video and shared a set of images yesterday (October 9th) showcasing the complete specifications of the "Magnus" APU, the core chip in Microsoft's next-generation Xbox console.
Microsoft's next-generation console revealed: 192-bit bit width and support for 48GB of GDDR7 video memory.
The console, codenamed "Xbox Next," is powered by a custom AMD APU codenamed "Magnus." Leaked information indicates that Microsoft plans to officially launch the new console in 2027, coinciding with the launch of Sony's PlayStation 6. In terms of graphics processing, the "Magnus" APU integrates a powerful GPU based on the RDNA 5 architecture, boasting up to 68 compute units (CUs) and at least 24MB of L2 cache.
According to previous leaks from MLID, the Sony PlayStation 6's GPU is expected to have 52 to 54 RDNA 5 compute units. Therefore, if the information is true, the next-generation Xbox will have a significant advantage in graphics core size. Furthermore, the new console will feature a 192-bit memory bus width and, for the first time, up to 48GB of GDDR7 memory. This capacity and bus width also exceed the rumored 40GB and 160-bit bus width of the PS6. Regarding the processor, the "Magnus" APU is expected to utilize AMD's future Zen 6 hybrid architecture, comprising up to three high-performance Zen 6 cores and eight energy-efficient Zen 6c cores, sharing a 12MB L3 cache.
To keep pace with the AI era, the new console also integrates a dedicated Neural Network Processing Unit (NPU). This NPU offers two power modes: delivering up to 110 TOPS of computing power at 6W, and 46 TOPS of computing power at a low power of 1.2W. The leaked spec sheet shows that the "Magnus" APU uses a dual-chip design with a total area of approximately 408mm², and the thermal design power consumption (TDP) of the whole machine is expected to be between 250W and 350W.
