AMD "Siren Halo" APU Rumored to Pair Dedicated GDDR7 With LPDDR Memory
AMD's next big Halo APU might ship with two separate memory pools, if a new leak from Gotou_3rd on X is accurate.

AMD's rumored Siren Halo APU would feature dedicated GDDR7 memory alongside LPDDR system memory, according to a leak from November 12. This dual-pool approach differs from current Strix Halo and Gorgon Halo designs, which use a single shared LPDDR5X pool. The dedicated graphics memory would provide increased bandwidth for gaming performance compared to the unified architecture in existing models.
The shift to separate memory pools represents a significant change for AMD's lineup. Current Halo APUs like the Ryzen AI Max+ PRO 495 allocate up to 160 GB of their shared 192 GB pool to graphics, a configuration that has made these chips popular for local AI workload processing. The impact on AI performance with the new dedicated GDDR7 arrangement remains unclear.
Siren Halo would follow Medusa Halo in AMD's naming scheme, with the leaker suggesting the new designation reflects AMD's lack of a fully new Halo design planned for 2027. AMD added GDDR7 support to its Linux driver in September, a change previously associated with RDNA 5 graphics. The company has not officially confirmed Siren Halo, and no details on memory capacities, bus widths, or launch timing have been disclosed.
What happened
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.
