Hi, from youtube, I read that i9 2.4GHz is about 10% faster than i9 2.3GHz. Given the thin chasis and thermal, do a machine with 2.4GHz i9 and AMD 5500M 8GB still perform better than 2.3GHz i9 with AMD 5500M with 4GB?

We don't have an. reliable benchmarks at the moment, but at least according to Geekbench 5 results the 2.4 CPU has a healthy lead over the 2.3 one (around 10% in multi-core scores). I have also seen some screenshots of a person benchmarking the laptop, and the CPU seems to be able to sustain around 60 watts of continuous power draw, which is a big difference over the 15" model (that one could only do 45-50W).

As to the GPU, I am not sure why you think that chassis will impact the difference between 4GB and 8GB VRAM. Both 4GB and 8GB GPU versions have identical performance, it's just that one of them has more VRAM and would need to swap less if your application requires large amounts of data to be on the GPU

Thanks. Is there a confirmation that Apple uses the same GPU on the 4GB and 8GB versions? i.e. The difference is only the amount of VRAM? In the Windows world, there are different watt versions of Nvidia GPU and Lenovo is not clear on which ones they use.

The closest we got to an official spec is here: https://www.amd.com/en/graphics/radeon-apple-5000m-series

I haven't seen any confirmation that the 4GB and 8GB have identical clocks though. I suppose for this we need people to look at the GPU tools in Windows. This is what TechPowerUp says: https://www.techpowerup.com/gpu-specs/radeon-pro-5500m.c3463 but it seems that they got at least the TDP wrong (the rest of spec seems to match what AMD say though).

I think we're talking about fractions of percentages points, does it really matter for real world usage?

Thanks. I guess we need to wait for the Bootcamp drivers to be available first.
