Care to explain why Nintendo went with a modified Tegra 1 instead of a Tegra 2 variant in the Switch?

Care to break down how much say a Vega. or Pascal / Ryzen based APU would cost compared to the current cost of the PS4's APU?

Care to mention how much "4x 18650's" cost vs the Switch's battery, how the size of the batteries compare, and if these 18650s require any additional shielding or protection circuitry to prevent portable PS4 portables from maiming their users if something goes awry?

No one's really questioning whether the technology is there. There's $1200 laptops less than an inch thick with X86 processors, and AMD GPU solutions that will eat the PS4's lunch and go dead within an hour. No one is disputing that. But now we need to make such technology less than half the size, less than half the price, and double the battery life. So please, sort out the feasibility of making such a solution less than say, $400.

Is there a reason why you are ignoring price? The person you responded to has repeatedly made it clear they arent just talking about whether or not such a device is possible but also if it can be released at a reasonable price.

Sure.
I don't think people realize how inefficient the Playstation 4 SoC is. - You don't actually need a chip that is identical to the PS4 chip to achieve the same outcome.
Ergo. You don't actually need a 1.8 Teraflop chip.

The Playstation 4 chip was outclassed even on it's release, all of these years haven't exactly been kind to the Graphics Core Next 1.0 architecture or those based upon it. It's old, it's slow, it's inefficient, it's hot, it's power hungry... Vega and Polaris are significantly more energy efficient, but still pale in comparison to say Maxwell or Pascal, let alone Volta.

CPU wise, Ryzen slaps Jaguar every day of the week, throw it down on 12nm, get aggressive with binning, consolidate some other parts of the system into the SoC, lower clocks and voltages... And bobs your uncle.

And then get aggressive with battery chemistry, LiCoO2 or LiMn2O4 are good candidates or maybe even LiNiMnCoO2.
The Switch's battery is good for 4,300mAh.
4x 18650's could provide 12,000mAh.

Well you know there would be people that would buy a PS4 portable with the same games just because it's portable. We have a lot of people in VGC that put games having twice the value because you can play HH and console, or that a game is made better simply by being portable, etc... so there would be some market for a portable PS4.

Possibly because I can only go by what is happening in the general marketplace? 

Besides... This entire thread is speaking in hypotheticals, which is why my stance is: You cannot gauge the pricing of a Playstation 4 Portable, but certain aspects (Battery and so on) can be improved over the Switch for minimal cost by looking at what is available on the Market.

I mean Shit. Even nVidia has better Tegra SoC's than the Switch and had them even when the Switch release.

How dare you say Nintendo is using a solution that was basically about ready? They are the sole inovators of the industry with everyone else playing catch up... also please ignore all other hybrids or the HH that could be played on the TV, they all don't count because only Nintendo made it right.

What the hell are you going on about? When did anybody say anything that even came close to what you just said?

If you are going to make posts that stupid, you might as well just say nothing at all.

You know you could just as easily have said that to everyone that was saying Switch was a fantastic new idea that only Nintendo could bring right?

Well that just means your whole post was irrelevant to what the person you were responding to was asking.

They wanted to know if a PS4 Portable was possible while maintaining a reasonable price, size and battery life.

That is your opinion and I wholeheartedly disagree with your sentiment.
If you don't like my post, you are more than welcomed to ignore it.

Hows about you try adding something constructive to the conversation instead of ridiculing everyone?

Im sorry for coming off rude in my last comment to you, not my intention, i just dont see how ignoring the main point of a question provides a relevant answer. Maintaining a reasonable price was the main point, not whether or not the tech exists.

What you said was interesting and its nice knowing such a device can be made but if its going to cost $600 than it might as well not even exist because its going to sell like the N-Gage.

As for the 2nd part, how are you going to call me out on being non-constructive when Don's post was mocking people for things that were never said? Thats just stupid on his part, no way around  it.

I find it precious when you get a problem to mock people that you claim doesn't exist, so who I was mocking? And then do two personal attacks. Do you talk from an alternative reality where mocking inexistente people is worse than direct personal attacks?

And we both know that if you have been following several of Switch threads there were person talking about how Nintendo was the only one that could do Switch, that the others don't count because they didn't had the same success, or that they weren't as straight... while ignoring that Switch is basically a personalized NVidia Shield.

But sure, let's forget the mirror and attack the boogeyman out there.
