Despite impressive efficiency results in our review, AMD has now semi-officially confirmed that RDNA 4 will not make it to mobile devices in any way, not even as Zen 6 iGPUs. The good news is that this suggests AMD may eventually port FSR 4 to older generations, as the AMD Ryzen Strix Halo APU still uses RDNA 3.5 for its RTX 4060-tier iGPU performance, and the upcoming Medusa Halo iGPU is slated to deliver even more performance.
