Forums - Nintendo - "Wii U GPU is several generations ahead of current gen" Shin'en

So the lesson to be learnt here is that positive Nintendo news gets heaps of hits if it's tech-related? :p (Or new game announcements/trailers of course)

I'm interested to see whether Shin'en will continue to be one of the leaders in Wii U graphics, as they are now and as they were for the GBA, DS, 3DS, and Wii, or whether their lack of manpower will prevent them from matching the likes of Retro, Monolith, and Tokyo EAD in the long run.

Yeah sure. If current gen in your mind is a goddamn Pong console...

It is just semantics. They both share the same memory pool, both the processors can talk to each other via that memory pool, it's been well documented in the linux community where they develop there own graphics drivers, the difference is GPU's of today are far more progammable and can talk directly via it's own dedicated bus to the CPU instead of passing through the System Ram like with Intels Ring Bus.
But that doesn't mean it's not possible for a CPU and IGP not to talk to each other and provide assistance in older platforms via slower methods. (Which is the point of this entire discussion.)

That link you provided is also not in English, no idea why you would post it in another language when this entire conversation has been purely in English.
Here is the English version for those wanting to know: http://en.wikipedia.org/wiki/Non-Uniform_Memory_Access
Again, Intel had supported NUMA 5-6 years ago, starting with the Nahalem platform.
http://lse.sourceforge.net/numa/faq/

Intel will be taking it a step farther with Haswell with it's embedded DRAM that both the CPU and IGP utilise as a cache and can see what processor has what, much akin to what they do in System Ram, it is just another step up in the cache hierachy to hide the latency and bandwidth deficit that DDR3 has. (Only on the GT3e IGP's however.)

Now, I honestly don't see dedicated memory going away, how you came to that conclusion beats me.
For example, back on the Radeon Xpress/3000/4000 IGP's AMD included 32Mb - 256Mb of DDR3 (Or better) Ram dedicated to graphics. - http://www.anandtech.com/show/1537/17
Intel has gone with throwing a bunch of transisters for a large fast cache on the CPU die.

AMD will be introducing GDDR5 for Integrated graphics soon.

Lastly... As for PCI-E 3.0 bandwidth... It is 1GB/sec per lane in each direction, maximum of 32GB/s in total, PCI-E 4.0 will double that again.

 

Sorry for copy/pasting the wrong link I thought I copied the english version.

 

I am not sure we are talking about the same thing.

I never doubted this: "But that doesn't mean it's not possible for a CPU and IGP not to talk to each other and provide assistance in older platforms via slower methods. (Which is the point of this entire discussion.)"

This was never my point. I dont see how you took this from what I wrote.

 

I wrote: "I am refering to unified Ram which is just way more efficent and will come for PC in the future, also CPU GPU communication is better so in a sense they are ahead"

 

(I should've specified it that I dont mean just any normal unified RAM.)

 

You wrote: "PC had unified memory systems for decades, what do you think APU's are? What about any system with an IGP? The memory isn't split on such systems, the PC had unified memory systems far before the consoles, infact it was invented on the PC first."

 

Yes PC had unified memory systems but not HUMA thats different than what Intel did. It needs way less copying around data from pool to pool which uses CPU/GPU time, ram bandwith/space.

 

http://www.bjorn3d.com/2013/04/amd-huma/#.UarVu9jVb2s

"With hUMA, all processing cores (CPU and GPU, etc) share single memory address and operates at the same bandwidth. CPU and GPU caches both see the data stored in the memory and can access and allocate any location in the system’s virtual memory. Data no longer needs to be copied back and forth between the CPU and the GPU before they can be seen. The CPU can pass a pointer and its entire data structure to the GPU. The result from the GPU can be read directly by the CPU without the need to copy."


If its just semantics WHY are people excited (google it) why is anyone even talking about it. And how has this been done years ago ?

 

 

That dedicated Ram goes away is just a guess and the following just a personal opinion: I dont see why sending data between two pools of ram and CPU/GPU is benefitial for anything. I also think that HSA/HUMA is a natural progression. I think the unification of GPU and CPU is under way for years. And the design philosophy behind the consoles is what AMD/Intel ultimatively are aiming to achieve, on a broad scale on the PC market. This is obviously just a guess. But getting rid of GPUs and CPUs seems to be a long going trend. Intel with his Larrabee tried it before. Cell is the same basic idea. Now APUs. And using two pools is pointless anyway. I can see a (distant) future for Desktop PCs were you can just have a board with 1 chip and 1 Memory.  And if more power is necessary use two boards.

 

PC obviously will have the technology, but not on the same scale yet.

 

There are some things were Consoles are up to date and can expand on concepts due to not being tied to the modular PC Ecosystem. That is my whole point. Always was.

If you still think I am wrong please send me your answer per PM. I dont want to derail this thread anymore, if people see a problem with it.

At least 1st party games will be and look great I guess... Though, we won't see many 3rd parties taking advantage of this.


ZombiU already has, so I guess at least Ubisoft is already putting time into the hardware.

Really? I thought ZombiU looked very unimpressive myself. Certainly not even close to Trine 2: Director's Cut, Need For Speed Most Wanted U, or Nano Assault Neo.

Did you play it yourself, or just go by screenshots and vids? The graphical quality was pretty excellent from my standards. Granted, it didn't have the overly colorfulness Trine does, but colorful doesn't equal impressive graphics in my world. =)

I've seen it played by someone else. I don't see anything visually impressive about it myself; lighting and textures were mediocre, and character models and animations looked poor. It certainly didn't look like it was making use of the hardware.

I disagree somewhat, ZombiU may not indicate the full ability of the U but for a launch title developed in 7-8 months it's one of the better looking titles.

 

 

These are taken from Miiverse, character models and animations need work but overall the game looks good.



i think ZombiU looks cheap, but very good, the atmosphere created by the audiovisual presentation was actually the best part of the game.

I just don't see it as being in the same league as this:

This:

Or this:



I have ZombiU but I can easily say it doesn't look very good. Maybe if you are accostumed to Wii standards il looks good but it's quite poor to be an HD console title.



comparing late 100m$ games to ZombiU its pretty dishonest and unfair

compare it to Resistance
