Do you know that RTX 40 series with 5nm will consume more power than RTX 30 series? Being powerful doesn't really mean it will consume less energy. Currently, all graphic cards have issues with the power consumption as both AMD and Nvidia cant solve this issue.
Performing desktop RTX 3090 with only 120W is already revolutionary.
Beside, it's also about optimization. For video, PC cant even compete since Apple Silicons have media engines and ProRes Encodder/Decorder and M1 Max already beat RTX 3090 high end desktop.
Currently, Nvidia is dominating 3D world and that's because all of them are using CUDA. You might say AMD isn't powerful as Nvidia but it's not true. Halo Infinite proves that optimization is important. But Apple is the only company making both hardware and software for consumer and professional world. The level of optimization is totally outstanding and that's a huge advantage so who knows?
