Forums - Nintendo - Iwata Asks: Wii U (Hardware Devs + A look Inside the Wii U hardware)

Bloody hell, I love the design of the board, how they placed the CPU and GPU on a one, smaller board, the MCM. Less semiconductors, less consumption. It's just like "find a place to live closer to work, less time and money to reach each other" mindset.

Bad idea.  May as well keep it built in.

 

Besides, we have no idea how many layers the Wii U game discs could be.  It may be up to 3 layers deep.  Don't think I want to see the price tag on a 75 GB SD card based game.

If it's for backwards compatibility, it's a great idea. It leaves room in the consoles for future proofing by using the extra space for higher hardware performance.



A note on the minimalist CPU, from my understanding the vast majority of games are not CPU bound ...

It is entirely possible that Nintendo sees limited need to really develop a CPU that is (much) more advanced that the HD consoles because few games are really taking full advantage of what those consoles already provide.

^Don't know (understand) what that means...

Which part?

Well, almost everything... All I understand is that all the parts are really really small - smaller than most would have expected. But I don't know what that will mean for the games... Is it good? Is it bad? That part

Oh, it has nothing to do with graphics but with efficiency, lifespan of the console and cost. Chech the link to the digital foundry analysis and you'll understand some of the decisions.

Ok thanks :)



I'm on Twitter @DanneSandin!

Furthermore, I think VGChartz should add a "Like"-button.

How does that space equate to higher hardware performance?

Beef up the CPU/GPU. I know power efficiency is a big deal, but really would it be so bad if the console sucked 60W versus 35W? If they had done that they probably could've gone with more horsepower under the hood and flat out destroyed the PS3/360 without question.

I think Nintendo is too extreme with emphasizing the power requirements. Even if it is a big deal, you can always scale the power consumption down with later models.



No, it wouldn't because the devs would still be lazy and release pretty much straight port, some without optimizations. Also, even if the games showed tremendous leap, which they already have(Garden Demo, Zelda tech demo, Wonderful 101) people would still outright deny the improvements and says its not better than their preferred console while throwing calls to consoles that don't exist yet.

Assuming it could be put to use, adding more components in the vacant space. I'm not computer engineer, so correct me if I'm wrong.

I suspect this means that the Wii U (probably) is using between 40 and 50 Watts, and looking at it I wouldn't be surprised if the GPU is using 30 Watts. This could mean that the GPU could (at best) perform similar to the Radeon HD 7690M XT (TURKS core, 40nm, 25 Watts)

That would make it nearly twice as powerful as the X360 GPU. Seems spot on from what we've all seen, but the CPU looks like it could be a major bottleneck later on. I'm kind of worried about it. Hopefully they'll pull a F-Zero OK. I'm waiting for it for nine years now...


Looking just a GFLOPS, the Xenos pushed 240 GFLOPS while the Radeon HD 7690M XT pushes 696 GFLOPS, which would be (almost) 3 times as powerful; but still in the range that everyone was (realistically) expecting.

Nah. No way then. I must have mistook it for something else. Efficiency per watt of current transistor manufactuing methods doesn't come even close to that. A crude way of measuring how powerful a hardware will be but still. We're looking at 400-450 GFLOPS tops. 


But the 7690M XT is manufactured using a 40nm process, runs at 25 watts, producing 697 GFPLOPS, and averages (roughly) 25 GFLOPS/watt ...

While Nintendo could choose something else, it is entirely possible for them to use a GPU that is similar in performance running with similar energy consumption being that this GPU demonstrates it can be done.

First off, there's already plenty of extra space already that could be used for other componenets.  We haven't even seen the underside of the motherboard yet.

Secondly, to up the hardware performance, you only need to really worry about the CPU, GPU and RAM.  The CPU and GPU are on that square MCM with the 4 RAM chips around it.   Opening up all that space where the disk drive currently resides won't do anything all all for those 3 componenets.

It does certainly help build on the theory that they're off-loading a lot of the work normally reserved for the CPU.
