Noticeable but there'a huge gap between between where NX/PS4 is and midrange pcs it's clear as day with multiplatform benchmarks in some games at 1080p, it's noticeable in GTA5 which is a last gen product. I'm literally saying it after that controller thread people wanting or thinking that we're getting some mega good cpu might want to tone it down.
I mention the SDK because by no means whether it's rumor or my source am I hearing this amazing shit this thread is implying either. If it's amazing then let one company pull off what factor 5 did with the GC games in terms of high tech being done in a few months. Otherwise for all intents and purposes it's hogwash. I don't care if you can port low end indie game, that's something the X1 can do. Let see this system handle something like witcher 3, which could utterly prove my point hypothetically.
Ok, now you're coming off as some whining brat who wants Nintendo to release a midrange PC in a console form factor, which is impractical unless you want $599 US DOLLARS to make its return?
If it surpasses PS4 by a noticeable amount that should be enough for 3-4 years, it's not like the NX is going to be locked in for the next decade like PS3 and Xbox 360 were.
If the difference is enough to get games that struggle to stay at or above 30fps to maintain a constant 30 fps (like fallout, Witcher 3, dragon age, etc) then that should be great.
If Sony and Microsoft were releasing the Xbox 4 and PS5 next year than I could understand your argument about Nintendo not future proofing enough. But that's not happening and the XB1.5 and PS4k are not going to be huge leaps that surpass the NX to the point it won't be able to run ports of those games, because the vanilla PS4 and XB1 are still going to get playable versions of those games too.
And, let's not forget that CPUs, while important to gaming, are hardly used to their fullest potential (look at the difference between i5's and i7's in benchmarks) devs aren't making the most use out of multiple threads and cores yet. It's the GPGPU and RAM amount that are gonna be the grunt, so if those are much more (let's say gpu 1.5x-2x more powerful, and useable ram in NX is full 8GB instead of the 5.5 of the PS4) then the CPU being only noticeably more powerful isn't bad.
