A new leak suggests AMD’s Zen 7 Halo iGPU could bring serious heat, boasting up to 35% faster speeds compared to the Zen 6 Medusa Halo APU. If that holds up, AMD’s next-gen laptop chips might be ready to bully some desktop GPUs.
AMD Zen 7 Halo iGPU might beat desktop mid-rangers
According to Moore’s Law Is Dead, the Zen 7 “Grimlock” Halo APU may pack up to 64 RDNA 5 or 5.5 compute units. That’s a big jump over the Zen 6 Medusa Halo, which was rumored to top out at 48. Even if the CU count remains the same, MLID expects big efficiency gains thanks to architectural tweaks. That means better raw output, even at the same configuration.
There’s no official benchmark data, but projections point to a performance boost between 20% and 35% over the previous generation. If true, this could put Zen 7 Grimlock’s iGPU within striking distance or even slightly ahead of the RTX 5070.
Honor’s budget-friendly Watch X5 packs GPS, 120+ sports modes, and a 14-day battery all for just $63 in China.
Zen 6 Medusa iGPU was already strong
Earlier reports claimed the Zen 6 Medusa Halo’s iGPU would use the same die as AMD’s RDNA 5 desktop “AT3” GPU. That model was expected to slot in somewhere between an RTX 4070 and RX 9070 in terms of performance. While mobile parts are naturally power-limited, the Medusa Halo APU wasn’t exactly weak.
That context makes the rumored Zen 7 leap even more interesting. AMD appears to be shrinking the gap between high-end mobile and mid-range desktop graphics.
What the specs reveal about Zen 7 Halo iGPU
Based on leaked specs and commentary, here’s what we might see:
- Up to 64 RDNA 5/5.5 CUs
- 20 MB L2 cache (if same as Medusa)
- 20–35% performance boost over Zen 6 Medusa
- Possible desktop-class performance in a laptop form factor
That last point matters most. If AMD can deliver this level of GPU power in an integrated chip, it could reshape what’s possible on notebooks in 2025.
Zen 7 Halo iGPU may go beyond the RTX 5070
By comparing past numbers, MLID’s “napkin math” puts Zen 7 Grimlock’s iGPU above an RTX 5070 at least on paper. That’s a bold claim, and far from final, but not impossible. AMD has been steadily closing the gap in integrated graphics for years. Now it might leap ahead.
Final stretch before benchmarks drop
Leaks can only go so far. But if AMD’s Zen 7 Grimlock Halo iGPU really hits that 35% mark, we’re looking at a laptop chip that could threaten more than just last-gen desktops. The spice flows soon.
