The Xbox was using a Pentium/Celeron Hybrid. In that it used the same amount of cache as the Celeron, but it had the associativity of the Pentium 3, it also used the Pentium 3's faster Frontside bus of 133mhz when Celeron typically used 66Mhz or 100Mhz.

The GPU is also not a Geforce 2. The Geforce 2 was mostly a fixed-function design, the Xbox had programmable Pixel shaders.
It was infact a modified Geforce 3.

The Gamecube's GPU was made by a company called ArtX. That just happened to get purchased by ATI just before the Gamecubes release and thus an agreement also took place to throw an ATI sticker on every box.

Increasing a games resolution changes nothing about a games cost. Otherwise the PC would be the most expensive platform on Earth to develop for, which flies in the face that it has the most indie developers. (The PC has resolutions of 11,520x2160 if you so wanted, which makes 1920 x 1080 seem insignificant.)

What you are talking about is higher quality assets.

So you aren't actually disagreeing with me at all.

16nm is 20nm. 16nm is a rebranding of 20nm, but with the inclusion of Finfet.

It's also not a custom tegra. It is Semi-custom. - Even then I doubt the customization was anything more than an alteration to some minor logic.

The Switch has closer to 20GB/s of bandwidth due to the DRAM clock decrease.

However, it also has more bandwidth than the raw number imply due to hardware-based compression that the Playstation 3 and Playstation 4 do not have.

Plus, Nintendo is marketing it as both a handheld and a console. So it's both.

Actually, I think we're seeing more of Nintendo's creative side as time goes on. They're not using the same formulas and are finally creating new IP's and different concepts to freshen up existing series.

I would say Splatoon, Tomodachi Life, Super Mario Maker, Xenoblade Chronicles X, Star Fox Zero, Codename STEAM, Captain Toad: Treasure Tracker, Kirby and the Rainbow Curse were all creative games that released in the last two or so years.

Star Fox Zero is hell no uncreative. But the rest, yea. 

In fact - I'm going to go as far as to say that Nintendo is actually taking the criticism of the 2D Mario games and their unoriginality seriously and are trying to erase the "New Super..." series by making the plain 2D Mario a phone title and making the creative Super Mario Maker a dedicated console game. Will they release one on the Switch if the console is super successful? Probably...but I wouldn't be surprising if it was just like a small downloadable title that was used to hype up Super Mario Maker 2.0. 

Their RPG division in particular is legendary. 

With Star Fox Zero they tried to do something new with the controls and ability to have two seperate perspectives. It backfired but was creative thinking nonetheless.

I disagree. Gimmicks and creativity aren't necessarily exclusive from one another but in the case of Star Fox Zero it was them being so unimaginative that they thought the only way to make the game feel unique was use a terrible control scheme. Remakes of Star Fox 64? So imaginitive. 

But PS4 is 3 years old, besides that, it had a custom soc with the power of a mid range PC graphic card, not a tablet soc like Switch. PS4 pro just lauched this year with new AMD Polaris architecture and more than twice the graphic power built in 16 nm. And Scorpio will probably bring AMD VEGA.

And the main point is, Switch is mostly a tablet, so it really needs new transistor technology to bring power down on the go. So putting in it old Maxwell at 20 nm is not going to help. They went for cheap stuff, maximizing profits. Fanboys will buy anyway.

The Playstation 4's age is irrellevent. It is derived from half-decade old technology today.

Polaris is based on Graphics Core Next 4.0, which is an evolutionary update over prior designs, dating back... You guessed it. Half a decade.
Heck a large portion of AMD's 400 series lineup is rebadged older Graphics Core Next 1.0 and 2.0 parts destined for the OEM markets.

If Vega drops it will either be added on top of the 400 series stack or usher in the 500 series, again, mostly being rebadged parts stemming all the way back to Southern Islands/Graphics Core Next 1.0.

Tegra X1 is fabricated at 20nm Planar. Which is actually the same as TSMC 16nm, but has Finfet, Volta will be built on 16nm Finfet and double the performance.

However with architectural choices, you can reduce power consumption and increase efficiency. Two chips at the same fabrication level with the same amount of Transistors can perform vastly different and use vastly different amounts of power.

nVidia for instance takes a tiled based approach which has given them an efficiency edge over AMD since Maxwell, Tiled Based Apparoaches tend to be more effective at using minimal resources that are available like bandwidth and caches, so there is less wastage... Combine that with things like Colour Compression and the ability to execute two FP16 operations bundled together as an FP32 op and other architectural nuances and it's easy to see how nVidia manages to get such efficiency even on older fabrication process's.

And that isn't all either. Fabrication is only part of the story. - A chip built on an older and more mature fabrication node can not only be cheaper, but use less power on a newer node.

And even nodes like Global Foundries 14nm Finfet has wildy differing levels of performance/leakage, which greatly influences power consumption and clock rates.

And on Switch you'll still not get the same kind of games (and I could only use PSP that with a cable could be hooked to the TV and use PS3 control), still just being a little cheaper doesn't make it really a cheaper alternative. It isn't like Golf is the cheaper alternative to Ferrari, their purposes are completely different, even GT-R would have a hard time being sold as cheaper alternative even though it gets very close on performance.

Powerful and expensive handheld that can also double as weakish home console? That's PSV2! How could it fail?
