On the other hand, there is also mention of "putting it close to the rumored PS4K specs" if i read that correctly. It's a tad contradictory i think:
"My sources say it is marginally better than the PS4 and theoretically would be close to the "rumoured" PS4K specs."
The jump in GPU performance between PS4 and PS4K is supposed to be x2. So marginally better than PS4 yet close to PS4K... what does that mean? About 1.5x PS4 GPU? That's not 15-30% anymore.
Well, this is new info supposedly.
Also the 15-30% thing is a random guesstimate based off LCGeek's very vague estimation of the CPU power so I wouldn't take it so literally.
Eh, Imma just assume NX's graphics wil look generally the same as Xbone/PS4 to the casual observer.
