AMD's next big Halo APU might ship with two separate memory pools, if a new leak from Gotou_3rd on X is accurate. In a short post on November 12, the leaker wrote that "Siren Halo has dedicated GD7 VRAM." When asked whether that meant unified GDDR memory, like on consoles, or separate pools, Gotou clarified that LPDDR system memory would still be there. He also claimed that Siren Halo follows Medusa Halo, that Siren Point is basically a Medusa refresh, and that the new name exists because AMD won't have a fully new Halo design in 2027. There's no word on capacities, bus widths, or launch timing. AMD already added GDDR7 support to its Linux driver in September, a change widely tied to RDNA 5.

This would be quite a change for the lineup. Strix Halo and its Gorgon Halo refresh use a single LPDDR5X pool shared by the CPU and GPU, with the Ryzen AI Max+ PRO 495 supporting up to 192 GB, of which up to 160 GB can go to graphics. That shared pool is a big reason these chips are popular for running LLMs locally. Dedicated GDDR7 should give the iGPU far more bandwidth for gaming, though it's unclear how much memory AI workloads would get. The leaker also suggested Siren Halo could be related to Magnus, the AMD chip linked to Microsoft's Project Helix, though that is speculation at this point. AMD hasn't confirmed Siren Halo at all, so it's best treated as a rumor for now.
