Forums - Nintendo Discussion - Tegra X1 successor Detailed by Nvidia (likely NX SoC)

CaptainExplosion said:

Well shit, looks like the NX is getting the downgrade. -_-

Nvidia reports FP16 performance, when they mention how strong their Tegra X1 is... why? cuz big numbers fool people.

Sony & MS 's consoles are useing FP32 (twice as demanding) (16 x 2 = 32). Also known as half or full floating points.

Thats why Tegra X1 is 1tflop fp16, but only 500 Gflops when you meassure it the same way as the PS4 or XB1.

 

Does that answear your question? in a head to head compairison it looks like this:

FP32 the tegra X1 is just 500 Gflops (0.5  teraflops).

FP32 the PS4 is 1840 Gflops (1.84 teraflops).

 

The tegra X1 is 512 Gflops(fp32)

The tegra X2 is 625 Gflops (fp32)

So its a upgrade, just not a gigantic one.

 

Basically 1/3 the power of the PS4.

If your generious and say flops arnt all equal, you can probably give it a 10-15% boost or so.

Point still stands, its closer to 1/3 than 1/2, of the power.

That is assumeing they dont make a custom chip, or throw 2 of these chips into it or some such.

Ok, makes sense. Always read about the fp16 number and thought to myself that 1Tflop aint that bad, and it fits right in to the Xbox One mold of performance especially if they went with X2's... but but but.. wasnt that good afterall :<

That's a little on the cheap side, the hardware would be really poor if its forced to be that cheap. 

People need to understand this device will do everything a Wii U AND a 3DS does. To buy both today will cost you $500. 

Even a Wii + DS back in the day cost $400 combined. 

I think something like $269.99 for the base NX and if they even make one, $119.99 for the NX SCD dock, would be more realistic. $269.99 is still way cheaper than the $349.99 that the Wii U started at, I mean shit it would be cheaper than the Wii U is right now. 

To be honest for what Nintendo is attempting to build even $299.99 would not be out of the question. This is way more functional than a Wii U, and if it can run a lot of the more popular Android apps, that's quite cheap, an iPad Mini 4 with 16GB of storage is $400 alone. 

Sorry, the ideal part would be the 199$ handheld, the docking station Imho should be at least 200/250$ , Nintendo really doesn't want to make a console that costs more than 200$ at launch after what happended with the 3DS.

Nintendo needs to break that distinction, the NX is not a rinky dinky little cute handheld. 

It will be a tablet sized device most likely (a Tegra simply would melt the inside of a 3DS XL even). It will be able to play games on the television and on the tablet. It may even run Android apps. 

This is a new product category guys, this is not 3DS-2. 

Even for 3DS, I would expect a "3DS Tablet" to cost at least $250. Anyone who sees the NX and thinks it should be $199.99 (the same price as a 3DS XL) is being ridiculous IMO. 

The PSP launched very successfully at $250 too ... 3DS and Vita both had issues because they aren't smart devices and launched in the era of the smart device, I think this is going to be the big change from Nintendo -- NX will be a smart device (as in it will be able to run Android apps, maybe just the Nintendo approved ones, but apps none the less). Both 3DS and Vita quite frankly also had poor launch lineups. 

Even the original DS struggled for a while, people don't remember that now but it was being outsold by the PSP which was double the price almost for a lot of 2005 until they started to break through with expanded audience games like Brain Training and Nintendogs and released the DS Lite with New Super Mario Bros. that's when the system finally really took off in North America/Europe but by then it was almost 1 1/2 years old.

In fact the DS sales were a bit too sluggish that Nintendo actually had to drop the price of it by August 2005 to from $149.99 to $129.99. Not a big cut, but sales weren't exactly lighting the world on fire in the West for the DS. 

That just goes to show ... it's hard to sell any device when you don't have a good library, even the DS, the best selling portable ever had a slow-ish start.

Not really, Nvidia is not going to say anything until Nintendo announces it. But even then you can see on one of the Parker/Pascal Tegra slides ... "Gaming Applications" are mentioned specifically aside from automotive. 

Now why does this Tegra need to have bandwidth for "gaming applications". Hmmm. 

Also it's not just Eurogamer, MCV, IGN, and Wall Street Journal all confirm with their own sources. MCV's source has even seen the system running apparently. 

The same Wall Street Journal source also called the PS4 Slim early, and that's pretty much now confirmed too. 

it wouldnt the first time people jumped the gun and ran with a false rumor. 

 

however ill say if eurogamer report is accurate. NX will do same or worse than Wii U did adn that will be the end of their console run

Is not like the AMD powered WiiU did amazing, either.

Miyamotoo said:

Well we can look from other perspective, 625 Gflops is 3-4x stronger than Wii U.

Also like people stating, comparing GFLOPs between two different architectures (AMD Vs Nvidia) isn't a good idea.

Okay, but why not?

Because in benchmark tests for Nvidia and AMD GPU its vere offer situation that some AMD graphic has same or higher GFLOPs than NVIDIA graphic but NVIDIA has better performance in tests. Thats why its widely accepted that NVIDIA Gflops "more valuable" than AMD Gflops".

Also Emily Rogers started when she talked about NX power, thats very hard to compare NX power with PS4/XB1 consoles, she said NX power is closer to XB1 but that really is like you comparing apples and oranges. That statment actualy perfectly fits if NX relly using Tegra X1 or X2 chip.

No its not cheap because here you have two devices that are part of same platform, you can use NX SCD dock stand alone, but you could use completely separate Wii U and 3DS or Wii and DS because they are totally different and stand alone products.

In case of NX, we could have NX handheld for $149-199 and base unit for $99 very easy.

The Parker has two Pascal Tegra chips on it (aka the Tegra X2), so that's why people are keying on it. 

It looks like Tegra X2 isn't a huge performance boost over X1, but there likely are decent energy savings, architecture improvements, and the big difference is Tegra X2/Pascal can have 50GB/sec of memory bandwidth on a 128-bit bus, whereas Tegra X1 only can do half that. 

Memory bandwidth is key for gaming. 

everytime nvidia speaks it makes eurogamers nvidia rumor less likely imo o.o

Nvidia relly can't say anything that will disproves eurogamers infos, maybe only if they say loud and clear, we dont have any involvement with Nintendo hardware. :)



Soundwave said:
I think there's a slide that claims 625 Gigaflop performance for the Parker/Pascal X2, but Nvidia has also apparently said 750 Gigaflop, I think the discrepancy might be that Nvidia wasn't including floating point performance for the CPU in one of their examples, I dunno.

It could be all of the above.
Gflop is Physical shader units * 2 * Clock speed, it may be accounting for clockspeed changes thanks to Turbo.

The performance jump from X1 seems like it will be more the on the CPU side

vivster said:
Good thing that Nintendo always uses high end cutting edge technology or else people might think this is NOT the NX SOC.

Yeah I'm only going on rumors Also if Nintendo were using the X1 then development kits would have been out early 2015 not this year.

Denver 2 should be able to out-bench Jaguar. But... And this is the big but. There is only 2 of those cores plus the other Quad Arm cores.
Jaguar has more cores which should make up for the single-core performance deficiency.
I would probably need to spend more time looking at the lower-level details to know how they stack up though...

But in the end, we need to keep things in perspective. Both Jaguar and Tegra X2 has Tablet levels of CPU performance which is ultimately nothing to write home about.

For a mobile chip it sounds like a pretty kick ass chip, likely the best in class (though Apple's A10x may have something to say about that).

For a home console chip though ... it's definitely no XB1 or PS4, so y'know I guess whether you are happy about this will depend on your POV.

Yeah if it uses this chip it will be a great portable console, but i think Mobile SoC's are still bandwidth limited which is probably one of the reasons Nvidia stuck with 256 CUDA cores

It's actually due to energy consumption, not bandwidth.

nVidia actually doubled the memory bus and improved bandwidth efficiency by roughly 20%.

However... Tegra X1 was built at 20nm, not 28nm.
Tegra X2 is actually being built at a "20nm FinFet" that has been branded as 16nm FF.

Basically there hasn't really been a geometric feature size shrink to reduce power consumption like what we saw on the Desktop PC.

Mind that mobile devices usually go for extremely high resolutions, with most high-end devices using 1080p or 1440p screens. As those are pretty expensive, I can see Nintendo using a 720p-900p screen to cut costs and also avoid taxing the GPU. It's more like what Vita did with a 540p, it has a bunch of games that still look better than current high-end mobile games.

Whilst correct that mobile devices usually have high resolution panels... It's another matter entirely natively running them at those resolutions, mobile devices usually upscale everything.

Soundwave said:

Yeah LCD displays are the least of Nintendo's worries. I see 1280x800 7-inch tablets for like $99 retail. They'll be able to get a decent screen for dirt cheap thanks to the mobile boom those components cost peanuts now. It might actually cost more money for them to find a screen that's lower resolution than that because no one makes them, lol. 

Needs to be a decent panel type though, if it's Twisted Nematic... Shoot me now.
Verticle Alignment panels I would be fine with...
In-Pane Switching panels I would prefer, if it has a high refresh rate.

dongo8 said:

I think we also have to keep in mind that there is a high probability that the chip(s) going into the NX is/are most likely custom chips, so while the specs are interesting to look at, they most likely don't match exactly what will be in the NX. I can't wait until we get some official details of the darn thing! Another month or so...jeeeeeeeez

The chips will be semi-custom at most. Not custom.. There is a very big difference between the two.

Stefan51278 said:

Not a huge difference in perfomance you say? With doubled memory bandwith?

It's actually more than doubled in the real world.

JEMC said:
Soundwave said:

I'm not saying this is what Nintendo is doing but if their philosophy is to have PS4 ports just at a lower resolution, they then may be forced to have to keep a reasonably powerful CPU, because CPU processing doesn't scale down nearly as well, where for graphics you can do things like reduce the number of pixels that need to be rendered by 1/3 (600p res) or even 1/4 (540p res) for portable play. 

Nintendo said that it wanted to appeal both casuals and core gamers, not that they wanted to get PS4 ports.

They can appeal to "core gamers" by, given that they won't need to develop 2 versions of several games (as always, if they go hybrid), develop new IPs that can appeal to that market like Splatoon or Xenoblade do.

If nVidia uses Transmeta's code morphing tech in Denver 2 successfully... Ports might actually be really simple and easy, still won't be optimal as building a game/engine natively for the hardware though, but certainly a better predicament than the Wii U is in.

Miyamotoo said:

I wanted to wrote that, Nintendo always uses custom chips, in this case most likely custom design of X2.

As chips grow in size, feature more transisters and become more intricate and do more... The less financially feasible it is to have custom designs.
It will be semi-custom at most, it will still be Tegra, but with a couple of minor changes to suit what Nintendo wants, but overall it's still Tegra.

JRPGfan said:

Yep 625 Gflops is the same number Ive read other places too.
Maybe the NX will have this when its docked and can use more power, than when its used as a handheld.

Still this means at most it ll be 1/3 of the PS4, in terms of power (when docked and not downclocked).

Pretty powerfull for a handheld. Not that great in terms of a home console.

No.

Werix357 said:

Yeah I get what you're saying but from a business perspective it would be smart to make an SoC that can be used for multiple purposes. CPU'S have always been a weak spot for portable consoles and from what I've read about the PX2 is that the majority of the drive focused stuff is external to the CPU and GPU portion of  the chip

To be fair though... CPU's have slowly becoming more and more irrellevent for gaming as time goes on.

If we were to go back to the early days of the PS1... Things like lighting calculations would have been done on the CPU, eventually they were moved onto the GPU.

Of course there will always be a need for CPU's as serialised processing is better suited to being done on the CPU with high levels of serial performance rather than parallel based processors like the GPU.

FunFan said:
History says Nintendo likes custom chips. For better or worse.

Things change though... Technology doesn't stand still for no one.

CaptainExplosion said:
Werix357 said:

If you look at discrete GPU'S and compare GFLOPs between AMD and Nvidia you'll notice it doesn't always reflect actual performance.

Do we have specific examples of this happening to games?

Yes. Go look up the benchmarks at Anandtech.com

Mbolibombo said:
So I was under the impression that the X1 chip was capable of 1TFlop ? How come the X2 is just 625 GFlop?

Or is this page just bonkers? http://www.anandtech.com/show/8811/nvidia-tegra-x1-preview/2

Because there are different types of Flops.

The X1 is indeed theoretically capable of that claimed number.

shikamaru317 said:
CaptainExplosion said:

But seriously, why would the X2 have only 625 GFlop instead of more than it's predecessor?

X2 is 625 gflop FP32, which is more than the 512 gflop FP32 of X1. I assume that FP16 will see an improvement over X1 as well.

625 gflops FP32 is kind of disappointing though, I was hoping for around 800 gflops FP32 for X2.

FP16 is usually double the performance of FP32 with Tegra.
So it should be 1250 Gflop for Tegra X2 in FP16 tasks.
Not that's actually that important anyway.

JRPGfan said:

Sony & MS 's consoles are useing FP32 (twice as demanding) (16 x 2 = 32). Also known as half or full floating points.

Thats why Tegra X1 is 1tflop fp16, but only 500 Gflops when you meassure it the same way as the PS4 or XB1.

FP16 is important because it's actually important for mobile, it's what the majority of mobile applications use due to the energy efficiency advantages it brings.
AMD's GCN 1.0 doesn't have native hardware support for it though because it's not a mobile centric architecture first and foremost.

AMD's GCN 4.0 does have Half Precision support with performance equivalent to single precision, which is likely what Scorpio and Neo will be based on.

Contrary to popular belief, it's not some conspiracy theory from nVidia to make it's hardware seem more capable than it really is... People just need to learn what floating point is all about.

nomad said:
If it hasn't been said yet, then I'll say it. That is not a mobile SoC.

It actually is though.

they've stated parker is for their automotive cars

https://blogs.nvidia.com/blog/2016/08/22/parker-for-self-driving-cars/?__prclt=loGXBCSr

The architecture scales depending on clock/voltage so it can go from Tablets up to Industrial or Servers.

zorg1000 said:

Sure it will, remember if the rumors are true than this is a successor to both 3DS AND Wii U. When combined those devices get a solid amount of 3rd party support from Japanese, indie & kid/family friendly games.

I think 3rd party support will come down to how successfull the device is.

It's one thing to scale your game downwards to suit weaker hardware... It's another thing entirely for it to be financially viable if you don't have a market.

The Xbox One is vastly superior in multiple aspects.


Soundwave said:

It will be a beast for a handheld, a little more moderate for a dedicated stationary gaming device though.

I think it will be a little more potent than some people realise... And a bit weaker than what some other people realise as well.
To me it's a good middle ground between the Wii U and the Xbox One, like a half-gen device, just with more modern graphics effects.

But they also said it would be a home console with a separate component that could be taken anywhere. This isn't the case if we're going off the tablet dock station rumor.

Thats basically same concept, based unit is home console and you can take with you handheld, ofcourse they didn't know all details year ago, but concept is basically same, hybrid platform.

But it says BOTH will recieve top end tech. There's no way they're going to put out a console that's over $400. With the console that has a andheld that can be bought seperately (which is what the link implies) it makes sense as you can upgrade as needed and wanted. With a handheld that docks you cannot, and would be absolute financial suicide.

It's the Wall Street Journal guy you're referring to right? He's since come out and stated what Eurogamer reported is basically what his sources are telling him. Odds are in that initial report he didn't quite understand the unit/concept. That older article (from last October) said the "exact shape of the NX hardware is not clear yet".

It's hard to take something that has info we KNOW is false and try to say a part of it is true. All I'm saying.

I really don't see what you try to prove here, from statment its obvious they were not sure about form factor or number of devices (very first sentence is "The exact shape of the NX hardware isn't yet clear") even they were right about concept, but they sound confident about that NX will use industry-leading chips.
