AMD’s next halo APU for laptops is shaping up to be a desktop-class powerhouse. Codenamed Zen 7 Grimlock Halo, the chip is rumored to succeed the Zen 6 Medusa Halo and push integrated graphics performance to new heights thanks to an RDNA 5/5.5 iGPU that could challenge dedicated mid-range desktop GPUs.
According to information shared by Moore’s Law Is Dead, the Grimlock Halo iGPU will at least match the compute unit count expected for Medusa. Earlier reports pegged Zen 6 Medusa Halo’s integrated graphics at 48 CUs with 20 MB of L2 cache, closely related to a desktop RDNA 5 “AT3” GPU die. Building on that, Grimlock Halo is said to target 48 CUs at minimum and could scale as high as 64 CUs, delivering an estimated 20–35% uplift over Medusa’s iGPU.
The CPU side shouldn’t be lacking either. Zen 7 Grimlock Halo is reportedly configured with up to 36 Zen 7 cores, positioning it as a flagship-class APU for premium gaming laptops and creator systems.
What makes these leaks especially eye-catching is the potential graphics comparison. If the projected 20–35% iGPU gain over Medusa holds, Grimlock Halo’s integrated RDNA 5/5.5 graphics could rival or even beat a desktop-class RTX 5070 in some scenarios. For context, many benchmarks place the RTX 5070 roughly 28% ahead of the RTX 4070, so the math suggests a genuine shake-up for integrated graphics—though final outcomes will depend on clocks, power limits, memory bandwidth, and drivers.
Key points to watch:
– Zen 7 Grimlock Halo is the expected successor to Zen 6 Medusa Halo in AMD’s laptop APU lineup.
– RDNA 5/5.5 iGPU rumored at 48–64 CUs, potentially 20–35% faster than Medusa’s iGPU.
– Up to 36 Zen 7 CPU cores are reportedly on the table.
– The integrated GPU could challenge mid-range desktop cards, potentially reaching or surpassing RTX 5070 territory under favorable conditions.
– All figures are early and subject to change as silicon, clocks, and software mature.
If these projections materialize, Zen 7 Grimlock Halo could redefine what a single-chip laptop platform can do: smaller, lighter designs with longer battery life, yet capable of high-refresh 1080p and even solid 1440p gaming without a dedicated GPU. Handheld gaming PCs and compact creator notebooks would stand to benefit the most.
As always with early leaks, treat these numbers as provisional. Official specifications, performance targets, and release timing will determine how disruptive Grimlock Halo truly becomes once it lands in next-gen gaming laptops.
