This is something truly...fun and exciting, and nowadays in the realm of laptops this is extremely rare. It's pricey, it's polarizing, but it's definitely different in many arguably good ways, and it comes from Asus, unsurprisingly.

That an extra ~150% TGP can only squeeze ~20% performance out of the current generation of Nvidia is quite shocking. They downplay Max-Q for years yet this suggests a good portion of thin&lights have the potential to reach a very high performance level, and in that light Apple's integrated graphics don't seem so pretty anymore. More like certain laptop manufacturers are artificially fragmentizing the market, intentionally reserving high performance graphics for thick and heavy models. A hypothetical XPS 15, at ~1.8kg and <20mm could come very close to 4080 performance with a hypothetical 4090MQ, yet the reality is such performance is reserved for >2.5kg, ~28mm devices.
