Key Takeaways
1. The AMD Zen 7 Halo APU’s integrated GPU (iGPU) may match or exceed the 48 Compute Units (CUs) of the Zen 6 Medusa Halo iGPU, potentially reaching up to 64 CUs.
2. The performance of the Zen 7 Grimlock Halo iGPU is speculated to be 20-35% better than that of the Zen 6 Medusa Halo iGPU.
3. The iGPU in the Zen 6 Medusa Halo is expected to perform comparably to the RTX 4070 desktop GPU, with the Zen 7 Grimlock Halo iGPU possibly outperforming the RTX 5070.
4. The Zen 7 Halo’s iGPU shares the same die as the RDNA 5 desktop “AT3” GPU, hinting at advanced graphics capabilities.
5. The article mentions available purchase options, including the GMKtec AI Mini PC featuring the Ryzen Al Max+ 395 Strix Halo APU on Amazon.
Earlier this month, a major leak from Moore’s Law Is Dead gave us insight into AMD’s Zen 7 specs and performance, covering everything from Zen 7 EPYC to the Zen 7 “Grimlock” AM5 desktop CPUs. The leak also included some information about the Zen 5 Grimlock Point and Grimlock Halo mobile APUs. During a recent episode of the Broken Silicon podcast, MLID hinted at the final performance and configuration of the AMD Zen 7 Halo’s integrated GPU (iGPU).
Potential Performance of Zen 7 Halo iGPU
According to MLID, the iGPU in the Zen 7 Halo might at least match the Compute Unit (CU) count of the Zen 6 Medusa Halo iGPU. Back in August, MLID reported that the Zen 6 Medusa Halo APU could come with a 48-CU iGPU along with 20 MB of L2 cache. Interestingly, it is expected that the iGPU in the Zen 6 Medusa Halo will share the same die as the RDNA 5 desktop “AT3” GPU.
This means that the iGPU in the Zen 7 Grimlock Halo APU could have 48 or even more RDNA 5/5.5 CUs. MLID speculates that the CUs could reach as high as 64. While no specific performance metrics were provided, it is suggested that the Zen 7 Grimlock Halo iGPU could perform 20 to 35% better than the Zen 6 Medusa Halo iGPU.
Comparing Performance to Current GPUs
By doing some rough calculations, MLID suggested in an earlier leak that the performance of the AT3 RDNA 5 desktop GPU might sit between the RTX 4070 and RX 9070 (which is available on Amazon). Given that the iGPU in the Zen 6 Medusa Halo will be power-constrained, let’s consider the performance of the iGPU to be at the lower end of MLID’s projections, comparable to an RTX 4070.
From our testing, the RTX 5070 desktop GPU is about 28% quicker than the RTX 4070 desktop GPU. Since MLID anticipates the Zen 7 Grimlock Halo iGPU to be 20-35% ahead of the Zen 6 Medusa Halo iGPU, the iGPU in the Grimlock Halo could potentially outperform the RTX 5070 desktop. However, as always, MLID’s figures are preliminary and not final, so our calculations could be significantly inaccurate.
