THat is not what anyone who knows anything is saying.

Jesus you all jump to conclusions. People who understand this say there is still A LOT of unknown in this GPU. They will update when some more is understood, but right now its still way too unclear to be making ANY judgments.

 

Kinda why I haven't updated my comparison thread yet. They are actually getting even more help from chipworks to fully understand the many areas that are clearly something unique to Nintendo and not based on standard GPU construction.

We are talking about raw power... not about the other specifics hardware units in the chip.

Those other parts are part of the raw power.

How does it come with this: http://www.vgleaks.com/world-premiere-wii-u-specs/


You mean compare? God knows it doesn't even look like a GPU, it's like opening the hood of your car and finding something that doesn't look like an engine powering it.


So it's like a Volvo, LOL.

What would Sheldon Cooper say to all this?

God those idiots at NeoGAF can't even calculate something
8 rops + 20 Alu's make 160 Alus. 160 alus @ 550 MHz is 352 GFlops not 176 GFlops.
Still clockspeed and fillrate isn't really that impressive at all not that is says everything.

WTF?

1 AMD ALU do 2 operations per cycle... so 160 * 2 * 550,000,000 (550Mhz) = 176,000,000,000 = 176 GFLOPS .

And forget the ROPs because there are individual units... 8 CUs... 20 ALUs per CU... 160 ALUs.

They can have the number wrong but the maths are right for sure.

I scrolled entire thread looking for BlueFalcon post. He hasn't posted yet. Some one make sense out of this.

he's a PC person like me, so he'd prolly have the same response as me, this shit is not even in the PC territory, it's too damn customized lol.

I see. Thanks for the reply. So customized like PS2/3 and unlike 360/PC. Good or bad though? Better performance over time i assume. 

Can't say if it's good or bad, if it does have fixed functions combined with modern tech then at least the fixed function parts would be incredibly fast and uses very low power and take very little space on the GPU while the modern part would be for custom shaders and that'd also explain the low power usage we've seen from games so far. It'd be very efficient but at the same time, devs can't be bitches about it or it'd never work out, would new engines like UE4 be possible on it? Yes. Would Frostbite 2 run on it? Yes. Will they run as well as Nextbox or PS4? Hells no, but it can be done.

All i see, are some house/ranch roofs with dirt fields....

Well maybe this is what Nintendo meant when they said they would work with third party more. If they need help, Nintendo will give it.

Since its so custom... they'll have to.

That's actually quite funny, Lol.

Unless Nintendo pays the bills I highly doubt Epic will "waste time" porting the UE 4 to the Wii U.
