So which CPU will you choose: AMD Ryzen 9 5900HX or Intel Core i7 11800H?

5900HX is such a scam. Its core advertised feature is not present in it(overclocking). It's neither unlocked for overclocking or undervolting, which any unlocked chip should have. 11800h is ACTUALLY overclockable\undervoltable despite not being advertised as such. Can reach 15000 points in Cinebench R23 because of that in some laptops.

the iGPU in 5900hx is also 2 times faster than the Intel UHD graphics in 11800h. Ryzen is better for sure.

it's not better, it's a scam. It doesn't have the overclocking AMD advertised on the official presentation. Nor it is undervoltable. In fact, in best-cooled laptops and if undervolted, 11800h is faster than 5900hx. If I chose an AMD laptop for the best battery life though, I'd choose 5800h which is an actually good CPU and has all the advertised features, while also not overpriced like 5900hx.
