According to leaker Gotou_3rd leaks, AMD is said to be working on a new silicon variant, Siren Halo. This is significant because this hints towards a low cost gaming approach for next-gen. It's something consumers should be on the lookout for. How does this chip play a role in the RDNA 5 ecosystem.
Leaked AMD Siren Halo chip shares RDNA 5 silicon with next-gen Xbox Magnus
Siren Halo is said to be a rebranded Medusa Halo chip which was discussed earlier. This chip is made for next-gen Xbox consoles as well as PC platforms. This silicon is going to be used alongside Magnus for the next gen Xbox.
- Memory Support: GDDR7 and LPDDR6 (or LPDDR5X)
- Architecture: RDNA 5
- Relation to Magnus: Likely shares AT2 specification RDNA5 graphics units
- Target Platform: Next-gen Xbox / PC
It supports GDDR7 for video memory and LPDDR6 or LPDDR5X for system memory. This likely uses RDNA 5 for graphics, same as Magnus. This employs LPDDR as an additional memory pool for cost and bandwidth of AI.
We discussed earlier the AMD RDNA 5 Launch Delayed to Late 2027 as Only AT2 GPU Ships This Year report. Previously, we know that only AT2 GPU will ship this year. This means, we'll have to wait for Siren Halo to release.
When it comes to the Magnus chip, it comes with Zen 6 or Zen 6c CPUs. This also features 68 compute units of RDNA 5 with 48GB of GDDR7.
The latest reports are saying that it's highly likely that both Siren Halo and Magnus use the same silicon source. But according to leaker Gotou_3rd, there's no direct proof that they're using the same production source. And we still don't know which exact generation LPDDR will be used. Either LPDDR5X or LPDDR6.
