Oh common, twist it all you want. You said what you said. :P 
Besides, the video never mentioned the Wii, Nintendo or Xbox.

Twist? I'm saying that Sony GDDR5 + eDRAM tested approuch is not like the DDR3 + eDRAM found in Wii U lol... Cerny was talking about PS4 and not Wii U lol.

I'm no expert, but if the 360 managed just fine with 10MB of eDRAM, shouldn't 32MB be enough for a framebuffer with lots to spare?

32MB is what you need for a 1080p framebuffer... less than that should really be a bottleneck for 1080p.

So, Nintendo sacrificed horse power to the speed of caches and latency. They have only 320 Stream processors, when compared to PS4's 1152 and Xbox one 768 stream processors. They should have balanced the hardware atleast to the level of Xbox one.


The Wii U's "Stream Processors" aren't comparable to the Xbox One or PS4's GCN pipelines.
The Wii U is more than likely using a VLIW5 shader architecture which isn't optimal for next generation games for multiple reasons.

It's still a few multiples faster (Around 3x) than the Xbox 360 and PS3 GPU's and can do far better (and more) effects with little performance penalty, but it really can't compete with the other big white elephants in the room in any metric.

Ok, so let's assume Wii U's RAM is faster. It's still bottelenecked by nearly everything else. It's like putting 8GB RAM on a Sega Genesis. It just doesn't do much when its CPU and GPU aren't up to speed.

Could be good news to the Xbone against PS4, though, because it is overall more powerful than Wii U to take advantage of that RAM architecture's potential, like Cerny said.


The GPU is not the "gimped" component in the hardware. It's the underclocked, fairly basic CPU. The GPU itself is fine and perfectly capable of keeping up with next gen demands.



Actually, you'll probably find, given Nintendo's hardware history, that the Wii U is a balanced system. You have to remember that early reports of the CPU being 'weak' were on early dev kits and made by developers who hadn't really got their hands dirty.

Developers also only had access to 2 out of the 3 cores early on too.

We know that Expresso isn't suited to floating point work but the same can be said of the CPUs in the PS4 and One too. That's why all 3 platform holders have gone for GPUs with Compute functionality.

One advantage that Expresso has over the other two CPUs is a ridiculously short pipeline, just 4 stages. The PS4 CPU has a 17 stage pipeline as far as I remember which means that in comparison, along with the eDRAM setup, Expresso is going to be crazily efficient.

With regards to the OP you most certainly won't see throughput that high, probably not even a third of that...but in terms of real world performance it is going to be impressive, developers have done nothing but praise the memory so we really don't have that much to worry about.

I agree. Couldn't have said it better myself.
