1840 / 397 = 4.64

Make it 5 Switch's just to be on the safe side.

Then give it x7 memory bandwidth of the switch, and double its ram amount.

Gonna need some good quality Duct tape.

The Xbox 360 and PS3 sure as hell cant run mariokart 8-deluxe at 1080p 60fps. 

Dark Souls Remastered will run 1080p 30fps with graphical improvements over the original, which was 720p

Fifa 18 for Switch is 1080p 60fps, with a sizeable graphical improvement over the last gen version, which also runs at 720p.

Yes, it obviously not as powerful PS4/XB1, but to say it is on merely on par with last gen consoles is plain wrong.

Always moving goalposts I see. 

Sony doesn't show any signs of releasing any kind of dedicated portable gaming hardware. ;) 

Also PS4 games take up way too much memory. Cartridges are expensive and so is internal memory. PS4 portable won't work unless the prices of cartridges drop dramatically. We already see many third party publishers releasing Switch games that you have to partially download (LA Noire, Doom, NBA2K18, etc.)

Then don't put power levels behind it. It's much closer to the xbox one. Just don't.

I will begin by responding to the main article. I think it will be a few more years until we get an SOC from AMD powerful enough and power-effecient enough to fit into a device like Switch. Although AMD has made major leaps with the new Ryzen 5 mobile (albeit those are still to constrained to fit into a device the size of the Switch, but the point is that the technology is moving quite quickly). On a personal level, I would love to see a portable version of the Playstation 4 because, as portable gamer (and one with a PS4 but with little free time to actually use it much), it would give me access one of the best gaming libraries anywhere. I really hope Sony does eventually make it happen, even if it ends up being a bit more expensive than the Switch is now (I would certainly buy it day one); though of course they have to look to see whether a higher price would appeal to the mass market.

This is such a flawed comparison. Just because those particular games are not on the Switch (4 of which are exclusive to Sony and so would never appear on the Switch; I could just as easily point to Wolfenstein 2, Doom, BoTW, SMO etc. to make a similar flawed argument) does not mean that the Switch is not capable of running such games. As SegataSanshiro mentioned, the vast majority of games that are available on both platforms (Skyrim, LA Noire, FIFA 18, Minecraft; Dark Souls and Bayonetta 1 remain to be seen since they have not been released yet) perform better on Switch. Based on these titles, one can assume that even the games you mentioned would at worst run on par with or, likely, even better if ported over (obviously though we will never know for sure because KillZone, Uncharted, The Last of Us, GoW3 are all exclusives; GTA V would be another interesting point of comparison if it ever comes).

the big thing you have to keep in mind is that mobile devices cost so much compared to consoles because they have extra components such as a built-in screen, which drives the price up. so there isnt really an exact science that can pinpoint exactly when a device fitting those exact criteria will be possible. but just from general observation and details, there are some areas that you can go off of. the first 8GB RAM smartphones have started appearing, and they are not cheap at all, costing over $1000, which is over twice the price of what you want. and that doesnt even consider the fact that it is a lower quality of RAM than consoles and PC use, so having that type of memory in a portable device doesnt even exist yet. and that doesnt even look at the processor type. mobile processors are actually up to par with console in terms of clock speed, depending where you look. my tablet has a 2.1 GHz processor, exactly the same as the PS4 Pro, but that doesnt factor in clock speed. and even that doesnt factor in the GPU. and all of that will be dependent on how much juice the battery can supply. and that all goes back to comparing battery types in high end smart phones... SO BASICALLY

given the standard rate for technology enhancements, being total power doubles every 1.5 years, i want to say such a device will be possible by 2025, and by 2028 it could be available at a $400 price tag

It's quite a bit better than PS360 when docked, but it's nowhere near to be compared to XOne.

I cant see how those 720p/30fps games beat for instance MK8D thats 1080p/60FPS game, ARMS thats 1080p/60FPS game, Mario Odyssey thats 900p/60FPS game, Zelda BotW 900p, Fifa 18 thats 1080p/60fps with noticeable graphical improvements over 720p PS3 version of Fifa 2018 game, Dark Souls 1 Remaster 1080p compared to 720p with terible frame rate...

I'm here for the nerdy talk.
