Will Wii U be more powerful than the PS4? Detailed discussion inside...

Well let's see. Let's take a look at the leaked Wii U specs and compare them to the leaked Orbis specs.

CPU

Wii U - 4 Core Power 7 architecture @3.0 Ghz, each core capable of 4 threads for a total of 16 threads

PS4 - A8 3850 Quad core @ 2.9 Ghz, each core capable of 1 thread for a total of 4 threads, on die Radeon HD 6550 core

GPU

Wii U - Radeon HD 4890 - 850 mhz core clock, 800 Stream Processing Units, 40 Texture units, 16 ROPS, 1,360 Gigaflops, 1 GB GDDR5 memory

PS4 - Radeon HD 7670(same exact as 6670) - 800 mhz core clock, 480 Stream Processing Units, 24 Texture Units, 8 ROPS, 768 Gigaflops, 1 GB GDDR5 memory

PS4 2nd GPU - Radeon HD 6550 - 600 Mhz core clock, 400 Stream Processing Units, 20 Texture Units, 8 ROPS, 480 Gigaflops

RAM

Wii U - 1 GB for the GPU and 512 - 1GB for the CPU. Total memory 1.5 - 2.0 GBs.

PS4 - 1 GB for the GPU and 1 GB for the CPU. Total memory 2.0 GBs.

Disk Drive

Wii U - Proprietary disk = 25 GBs per disk

PS4 - Blu-ray disk = 25 GBs single layer, 50 GBs dual layer

Conclusion

These consoles will be very close. The Wii U has a better GPU but when you factor in the second GPU in the PS4 APU working in crossfire, then it's pretty much a wash.

However when it comes to CPU, the Wii U wins easily with a processor capable of handling 16 simultaneous threads vs the PS4's only 4 simultaneous threads.

What sort of advantages this translates into is very difficult to determine at this point. One safe assumption is that both will run multiplats pretty much identical. Maybe the Wii U will have better framerates due to the better CPU.

You may see exclusive games for the Wii U utilize all of that CPU power and give us great AI and Physics.

One thing is for certain, both consoles will be much more powerful than the current gen machines and this time the Wii U will not lag behind. Well, of course this is only compared to the PS4.

It remains to be seen what the Xbox 720 has under the hood.

Comparing rumours? That's nice.MonsieurX

I can't believe you took the time out of your day to do a long comparison with only rumors and no facts.

Start with being more powerful than a 6 years old ps3 then you can move to ps4silversix_

Both Wii U and PS4 will be a lot more powerful than the PS3.

[QUOTE="silversix_"]Start with being more powerful than a 6 years old ps3 then you can move to ps4Xplode_games

Both Wii U and PS4 will be a lot more powerful than the PS3.

You can't stuff a 4890 and x4 CPU in that small of a box at this point in time. Expect a 4650-level gpu.

From what I read from a "source", the Wii U will be stronger than the 720, Xbox4, PS4, and PS5....but oddly, the Wii U would be bested and topped by the PSOne and N64.

Darn sources! I need to make a comparison thread when I get the chance. ;) :P

So the PS3 is stronger than the PS4 then? Chrome-

The PS3 specs are trash. It has a ONE CORE processor that is an IN ORDER architecture. That means while it is clocked at 3.0 Ghz, it runs roughly equal to a 1.5 Ghz out of order processor. So the CPU in the PS3 is really similar to a 1.5 Ghz that can do a total of 2 threads. It also has 6 SPUs which are more for parallel processing tasks.

The GPU is equivalent to a 7800 GTX. That GPU had dedicated texture pipelines and vertex pipelines. It had 24 Pixel pipelines and 8 Vertex pipelines. The total theoretical performance was 165 Gigaflops.

Both the Wii U and PS4 crap all over it.

The only concern I have is whether it can handle X3/PS4 multiplats at 720p. I was hoping for a 4830-level GPU, but after the Zelda demo I have my doubts. Carmack said the HD Twins will basically be 1080p systems with a nominal step up in visual fidelity. If the HD Twin rumors are true, and they use 6670 DDR5, they can handle games like C2 at 1080p at max settings. Acceptable, but nothing mind blowing. Devs have the advantage of fixed hardware, though. Smoke and mirrors goes a long way on consoles. Look at the transition from Gears 1 to Gears 3, or Uc1 to Uc3. The games will look great. Hopefully Ninty doesn't get left out by 3rd-parties this time.

They're not going to just grab an off the shelf 4890, it will be customized to fit in the Wii U. It will also be built on a 28 nm manufacturing process which will give it huge benefits in power effeciency and heat dissipation.

Well let's see. Let's take a look at the leaked Wii U specs and compare them to the leaked Orbis specs.

Wii U hardware is rumored to cost $120 to manufacture and they said they had to cut corners to ensure shareholders that it will turn quick profits. Sony is so high in debt they could make a mountain and Orbis rumors are all over the place, with some sources saying it will be stronger than durango and others saying it will be a bit faster than Wii U. Latest Xbox rumors place durango as haveing some monster 16-core CPU POWER7 IBM, which would be future proof for long into the future. it will also have dual HD7970-8000 gpu's working not in Crossfire but independently. the same source of that rumor also said it expects Sony to have an even stronger machine which is hard to believe. sources at Crytek have said they had to halt production on PS4 games due to sony changing the architecture from a 24 SPU Cell to traditional AMD setup. to sum things up no Wii U wuill not be stronger or even in the same league as Orbis/Durango in fact the gap might even be worse with Wii u as it was this gen with the Wii.

That's consistent with the specs in my OP. The PS4 will not use a variant of the Cell processor. It will instead use an A8 3850 APU.

There is no way that Sony would make a console so expensive that it would be significantly more powerful than the Wii U after what happened with the PS3, especially with the losses that they are taking.

The Wii U most likely will *not* have a HD 4890 based GPU. It would be too hot and consume too much power. This conflicts with the recent rumours about a "economical CPU and GPU". It's rumoured be similar to a HD 5570 which is a pretty low-end GPU and even worse than the rumoured HD 6670 in next Xbox and HD 7670 in next PS. Also, it's questionable if it will have 1.5 gigs of RAM (786 megs are likely) and we don't know the details about the CPU either (other than it's supposedly better than what the 360 has).

No it wouldn't, that GPU would run Crysis maxed in 1080p and pretty much any other PC game in DX10 mode (with possible tessellation enhancements under OpenGL) if they sticked it in a console. Quit comparing console and PC hardware. You don't need the same horsepower a PC needs for good results on a console. There's no way the next-gen consoles could have the latest and best PC tech.

Nintendo isn't making the same mistake twice. I think they will be taking a minor loss on each console sold so that they can have a console that can handle next-gen engines. Don't forget that this console is for hardcore gamers that are willing to pay large amounts of money for a console. The Wii U will be very far from economical.

It's rumoured to cost 180$ to make and 50$ for the controller and it's supposed to sell for 300$. This means it'll sell for a profit since start. Nintendo isn't stupid to make consoles that would sell at a loss. It's what keeps them afloat. The target market for Wii U aren't "hardcore" gamers but the "casual" gamers and the people who buy a Nintendo console for Mario and Zelda. It'll get more 3rd party games this time due to better specs and more suitable controller but don't expect too much. As for the next-gen engines - it's GPU will likely support full DX11 functionality so you'll see tonned-down ports of those engines.

Yes, it is true that the Wii U will convert casual to hardcore, but Nintendo is also targeting existing hardcore gamers as well.

Really? I thought they might put a fullsize card in there. It would fit...

I swear my Wii gets extremely hot, no way Nintendo is going for a loss-leading, overheating deathbox 360...and keeping it all secret that's it's a powerhouse so they show 720p tech demos to deceive investors and consumers.

Too much heat. It's better to have more but lower Ghz cores.

Are these confirmed specs or just rumored leaks?

I see what you did there and I applaud you for your efforts, but comparing rumors isn't proving anything TC. Especially when those rumors are referring to PC components being used in consoles. The architecture in consoles is very different to that of a PC, you can't just slap on a 7850 to the Wii U and believe it will be that powerful. There's lots of negotiating that goes on and at the end of the day the manufacturers are left with a product that's very different than what's available in the market.

Crossel777

Rumored leaks, don't expect any PS4 confirmed specs for a very long time.

I'm sure we'll see Wii U specs at (or near) E3.

Why are things still being made with 3ghz processor speeds? My next comp is having 5ghz or I'm going to wait until that's obtainable.YoshiYogurt

Why would you need more than 3ghz speeds? Technology hasn't reached the point where games are utilizing all that power, you're thinking of clock speeds as a one dimensional process where a 3ghz i3 is equivalent to a 3ghz pentium. There's a lot more to it than just the "ghz" that determines how powerful the processor is, heck most games don't even fully use more than 2 cores yet. It's rare to see a game that actually requires a quad core processor to use, but even then it's all down to the architecture. AMD's A8 processors are quad core yet they're only slightly more powerful than an i3 dual core processor.

Why would a 4890 be hot and consume too much power? You don't think ATI knows how to make that chip much cheaper and cooler by now? A 28nm 4890 would be a very effecient chip with low temps. Remember, they are not going to take a big 4890 GPU from 2008 and stick it in the Wii U. This will be a customized version made specifically for the Wii U.

Wii u have no chance for this GPU, you recall.. The original dev kit used an r770 chipset, much better than the r730 you recall..

The latest leaks, say that nintendo changed GPU to a much newer model with lower heat and power consumption, but also performs better.

The only thing matters me.. is how many stream processors wii U got, if its 500+ then its a SUPERB machine, comparable in graphics with the other 2.. if its letss than 400, then is going to struggle after 2 years of time.. Either ways, the cpu power of wii U, is ALOT superior than the ps4 and xbox720 (if microsoft use an IBM cpu, then xbox is going to be better). And it is oficial! IBM announced that the new cpu of wii U, got 300% more emended ram inside the cpu and it can offer thrilling gaming experience. Also, wii U will have the virtual controller environments, I mean to turn around and see a different view of the game world, with the controller.. Also this information by IBM, rejects the rumors by anonymous, that wii U is not capable for AI and Physics.. its a faulty mean by fanboys, rumor... it may be better in AI and physics from PS4 and xbox 720.

While the ps4 is not capable for that, in the luck of cpu cores. The 4core cpu by amd, cannot handle that (virtual controllers), so if ps4 comes with screen controllers, is going to be like eyefinity mode, nothing else... but is going to be strong in graphics

(I dont speak about the anonymous rumors)..

I just go by what I'm seeing, and there's no way in hell it's packing a 4850/4890-level GPU in that tiny little box, and selling for a profit at $300. Look at the size of this thing...

Game demos:

ME3 on my 4830 at 1080p with AA vs Zelda tech demo on the WiiU at 720p no AA...

I'd be more than willing to step into System Wars Bets and make it more interesting. Below 4830, no question. I'd almost guarantee people expecting a powerhouse will be disappointed.

The Zelda tech demo looks to be Radeon HD 4650/4670 level. They could change it to 4770 i.e. 128bit wired VRAM PCB with GDDR5 support.

PS; I have Radeon HD 4850 test machine and it has better results than Wii U's Zelda tech demo.

800 stream processor + 128bit wired PCB VRAM Radeon HD can be fited into Wii U's case i.e. clock it down to 500Mhz and drop the voltage a.k.a. Radeon HD 5830M (25 watts, 40nm TSMC low power).

I have similar Wii U size box with DIY ViDock (i.e. DIY external GPU solution for my laptop). Without an optical drive and CPU, my old 5770 (factory overclocked to 6770 levels) is pushing the DIY ViDock's cooling limits. 500Mhz version 5770 is possible for Wii U size case.
