Hardware Nintendo Switch Technical Specifications Discussion

[Yil]

Pretty much yeah, however, I'd trust the WSJ more than EG. they did get the hybrid part of the switch months before anyone else.

1080p is not 66% of 1440p. At least for unreal, it would run at 1080p. But on the other hand, it might sacrifice a bit visual to run at 60fps.

Several other things to consider about Takashi's rumours is that usb 3.1 gen 1 aka usb 3.0 does not support display port or even hdmi (can be converted via other means, but not directly) for that matter. And where does 3ds's 128Mbps comes from? Wifi?
Edit: Double checked and type-c gen 1 can still do display port and better charging (3A, 60w max) or (5A, 100w max), like MacBook 12 or Pixel book. Hopefully 60w is enough to satisfy docked performance.

No the speed of its data lines.
when he says 1440p i think he means thats its max resolution

Pretty sure internal connection should be way past 5Gbps. Even the usb-c port on the bottom is faster. Gen 1 usb-c also cannot deliver beyond 12w of power.
3ds's data lanes are more feasible, but where did he even get those? Mostly it's hardware devs who look into those.

He reported what ace Yasuda had said and he is a pretty noteworthy insider.

I trust him for the most part but I think he might be a bit confused about usb 3.1 gen 1 (i.e. usb 3.0) vs usb 3.1 gen 2.

I still think the screen is going to be 720p.

 

[TheDarkGreninja]

I still think the screen is going to be 720p.

Its the most likely for now, yeah.

 

[Yil]

Its the most likely for now, yeah.

Technically 720p to 480p can also be considered 66%, but I doubt Nintendo would be that stupid. It seems super sampling is used for portable mode (considering percentage), and the power gap between console and portable mode is while noticeable, not too fat apart.

Indeed, lol a 480p screen in 2017 would be a novelty.

Seems the UE4 switch presets might be fake.

Only the master edition. Master edition has dedicated support team and many things ue4 don't offer.

If Wolf is Switch then how are the presets fake? Didn't they just list the presets under "Wolf?"

Only master branch with heavy monthly subscription and Nintendo's approval have access to them, so kind of hard of confirm, but my money is on them being true.

1.) Eurogamers weren't necessarily 100% trustworthy. A73, being the smallest high performance cpu available and most suited to save space for gpu while retaining high performance, should easily hit double the clock.
2.) The latest Master build of UE4, which is not rumour, has demonstrated the switch with great performance. That means it's much beefier than tegra x1.
3.) TSMC's 16nm is cheaper and better than 20nm (most importantly cheaper). Nintendo will be making the same mistake all over again to choose 28nm and if Nvidia wants a long term relationship they will want to make sure Nintendo is up to date.

1.) Eurogamer was first to leak the hybrid form factor of the Switch while it was still known as NX so unless that was a wild guess they DO have sources. I've yet to see a single credible source point to A72, let alone A73. Nvidia seems to be still using A57s on Parker, their own Pascal Tegra SOC.

We have a Pascal Tegra with dual channel LPDDR4 and 2 Denver 2 cores, but it still has only 2SMs and A57 cores, not A73s. Perhaps Switch will have Denver 2?
Remember, NVidia and Nintendo started work on this SOC 2 years ago, so they're limited to tech that had to at least be in the planning phase then or the tech becomes an endlessly moving target.
2.) Switch UE4 defaults are level 2 for docked mode, level 1 for handheld mode. XBone, PS4 and PC are around level 3 default, so to put this into perspective, handheld mode has 40% the clocks according to Eurogamer, therefore, wouldn't UE4 level 2 be ~40% under UE4 level 3? That should tell you the power right there as a:
3.) Pascal @16nm FinFet with even 4 A73 cores and 3-4SMs would be ~65-90% the power of XBone, with the ARM CPU being clearly superior, and would not need lower UE4 settings.

Nintendo seems to be heavily prioritizing battery life and stability at the expense of sheer performance for Switch, but we'll see in January if that's truly the case.

1) Denver 2 is huge and that's why the gpu is so small. It's designed to work with mxm gpu.
2) 720p(possibly 1080p super-sampling) level 1 is 40% of 1080p level 2.
3) A73 is currently the best cpu core arm can offer, it's the successor of a72 and smaller than both a57 and a72.

I'd like to point out that 1Tflop of maxwell is more or less equal to 1.67 Tflops of GCN, this puts the Switch between XONE and PS4

Well i can confirm wolf is switch but i cant find the ini file.

GCN gen 1, not Polaris/ Vega.
Are you at master branch?

Also achievable with a custom Tegra based on X1 that has 4SMs and 512 CUDA cores(768MHz clock speed), no? ~80% of XB1 power, just in terms of FLOPs. Not forgetting of course that UE4 is a newer engine, optimized for basically anything that can run x86. PS4, XB1, and Switch are all much closer to being PC hardware than even last generation was.

Battery life is only an issue in one of the modes, and I thought rumor was only ~5 hours. You could get 720p at medium settings for 5 hours.

Yeah, GCN gen 1, against Polaris im pretty sure its much closer and Vega will destroy maxwell.
I'm not at master branch i have a friend who is however.
