The leaks indicate that Siren Halo will feature Zen 6 processor cores and RDNA 5 graphics. These chips will reportedly include dedicated GDDR7 memory for the built-in GPU alongside LPDDR6 memory support. If the hardware matches AMD's rumored Magnus APU, it could reach up to 672 GB/s of memory bandwidth using 28 Gb/s GDDR7 chips and a 192-bit bus. The Magnus APU design features three full-size Zen 6 cores and eight dense Zen 6c cores.

Reports also link the silicon to next-generation Xbox Helix consoles, which may use 68 compute units out of 70 available on the AT2 GPU die. Concrete details on maximum core counts and memory configurations remain unconfirmed.
