Pretty much what one would expect from a ~22% increase in GPU clock speed, I guess.

For all things AMD; come talk about Ryzen, Radeon, Threadripper, EPYC, rumors, reviews, news and more.

I thought much of the performance increase came from using faster DDR5 RAM with the 780M, but this seems not to be the case, it's faster even with the same RAM.
My guess would be scaling. Off the top of my head and a brief Google search seems to lead to 680m vs 780m using slower 4800mhz and 5600mhz memory.
Which leads me to now think they both scale pretty equally at this RAM transfer speed. However at 6400mhz, the RDNA 3 780M could probably start scaling higher compared to the 680m. Guess we'll never truly know.
Don't trust random youtube videos.

the gaming performance of the Radeon 780M is comparable to what we got in the past on Radeon 680M platforms, with differences within 10% between generations.
Not random at all. Also quite hard to fin 2 notebooks with same RAM and TDP.
