In brief
- Hardware leaker Gotou_3rd claimed on X on November 12 that an APU called Siren Halo has dedicated GDDR7 memory for its integrated GPU.
- According to the leak, the chip will still use LPDDR6 for system memory, suggesting a hybrid memory architecture.
- The leak suggests Siren Halo will replace the existing Medusa Halo design, while Siren Point is described as a refresh of Medusa.
- AMD has not officially confirmed technical details such as core count, memory capacity, or bandwidth.
A new model has emerged within AMD's "Halo" series of APUs designed for mobile and handheld devices. Hardware leaker Gotou_3rd, in a short post shared on X (formerly Twitter) on November 12, 2026, claimed that a chip called "Siren Halo" has a separate GDDR7 memory pool dedicated to its integrated RDNA 5 graphics unit. When asked whether this meant a unified memory architecture similar to consoles, the leaker stated that there would also be a separate LPDDR-based pool for system memory.
What does Siren Halo mean?
According to the leak, Siren Halo is the next-generation product set to replace AMD's existing Medusa Halo design. The same leaker claims that another chip called "Siren Point" is essentially a refresh of Medusa, and that this naming scheme was adopted because AMD will not have an entirely new Halo design in 2027. Previously, another leaker, Kepler_L2, had announced that Medusa Halo's name was changing without revealing the new name; it's now speculated that Siren Halo may be this renamed product.
Gotou_3rd also stated that Siren Halo could be related to the Magnus APU, reportedly being developed for Xbox's next-generation console. Both designs are expected to share AMD's AT2 RDNA 5 GPU architecture. The rumored configuration for the Magnus APU reportedly includes three full-size Zen 6 cores alongside eight dense Zen 6c cores, with the GPU side featuring 70 compute units, 68 of which would be active on the console side.
How might the memory architecture work?
Details such as capacity, bus width, or bandwidth have not yet been clarified. However, based on the figures discussed for the Magnus APU, it's estimated that using 28Gb/s GDDR7 chips with a 192-bit bus could yield approximately 672GB/s of memory bandwidth. On the system memory side, it's suggested that AMD may retain the 256-bit bus used in its current Gorgon Halo (Ryzen AI Max+ Pro 400 series) products. Earlier leaks regarding Medusa Halo had mentioned a 24-core Zen 6 configuration with LPDDR6 memory support; this increase in core density stems from Zen 6 architecture's CCDs (Core Complex Dies) housing 12 cores each (compared to 8 in Zen 5).
What does this mean for architecture and visualization workflows?
Such hybrid memory architectures, even as a design-stage leak, could eventually translate into improved integrated GPU performance in mobile workstations and compact desktop systems. If the claims are confirmed, architects and 3D artists using GPU-accelerated render engines like Blender, Twinmotion, or V-Ray could see thin-and-light devices with higher memory bandwidth, without requiring a discrete graphics card. However, this possibility is based entirely on a chip still in the design phase—neither a launch date nor final memory capacities have been clarified. Offices planning team hardware purchases are advised not to rely on this information for now and to wait for official AMD announcements.

The Siren Halo claim is currently based on a single leaker's post on X, and AMD has not offered any confirmation. Still, the hybrid memory architecture idea is interesting: dedicated GDDR7 memory for the integrated GPU could mean significantly stronger render performance in mobile workstations without a discrete graphics card. This could be an important development especially for architecture and visualization studios looking for thin-and-light laptops for field offices.
Offices in Turkey shouldn't rush on this point. Until launch date, pricing, and real-world performance figures are known, it makes more sense to base investment decisions on current hardware. While leak culture is exciting, it's best to follow such news for informational purposes only until a concrete product and official technical documentation emerge.
