That alone won't be enough. Strix Halo is not monolithic, and thus won't have good power efficiency, so you won't be able to compare it to the Pro lineup.
It may be able to match the M4 Max in raw multithread performance, but will loose in anything that requires memory bandwidth, GPU and power efficiency.
I am disappointed to find out that AMD used a 5nm process for Strix Halo
So for sure it will have worse efficiency than M4 series.
Regarding memory Bandwidth, the M4 Pro has 273GB/s (the M4 Max has +410 GB/s), compared to Strix Halo at 256GB/s (but includes 32MB Infinity Cache). AMD had a slide comparing rendering performance:
Not sure about GPU/gaming performance, but Strix Halo should be at least 2-3x faster than Ryzen AI 370. Which means it will also be faster than the M4 Pro in graphics.
Overall, this solution is still more efficient than having a separate CPU and dGPU laptop, and with such great performance AMD should be able to increase market share with Strix Halo against Intel / Nvidia / Apple.
