352 GFLOPS / 320 spu / edram until 550 Gbit /s (2 times gdr ps4p, and less latency) 

Wiiu have 2 screens.... 

That is a old thread from 2013, back before people really knew.

Now in 2016 we have people confirmed its 176 Gflops, after haveing looked at die shots of the GPU inside the wii u.

 

"The Rv770 has 180 lots of 5 shaders giving a total of 900 shaders of which only 800 were enabled on the full fat die as the other 100 were spares to increase yields. Looking at the latte die it appears to have 32 lots of 5 shaders which is 160 cores meaning 176 GLOPS is the correct answer." - Marlenus

 

160 x 2 x 550 mhz = 176000 flops  (176 Gflops)

 

Everything else beside what I just wrote above is wrong.

Now you know, stop spreading wrong information.

320 x 2 x 550 mhz = 352 Gflops

3-4 times the WiiU is fine. Horsepower is not what worries me about NX.
Nintendo consoles (expecially handhelds) should be easy to use and affordable.
According to most popular rumors the NX sounds like an overcomplicated expansive machine.

All that proves is Eurogamer was wrong too.

And there are more places that all say 352 Gflop is the answear.... but they are all old, and all come from the same wrong source.

Someone looked at something, came to a mistaken conclusion and said "its 352" and everyone everywhere on the web went "okay" and started writeing it was 352 Gflops. Very few sites go back to fact check on old stuff they wrote.

Neogaf thought it was 352 Gflops back then too. Now people there are saying its 176 Gflops.

Akeos look here:

320 SP theory:
"The issue with that Latte linked spec that you and OryoN discussed is that it has a serious flow in its numbers WRT the VLIW5 rumors: by the quoted numbers, Latte cannot be a VLIW5."

"Five CUs (compute units, AKA SIMD units) and 320 SPs (shader processors, AKA processing elements) means each CU should host 64 PEs. 64 is not a multiple of 5, and VLIW5 works with quintets of PEs. Not to mention the consensus is that there are 8 CUs on the die shot, and that's one of the few things there's a consensus about"

qoute - Blu Neogaf.


The problem is Neogaf has members that are devs, or nintendo people.
They know its VLIW5, a member (BG) that knows said it was so.
But that doesnt fit with the 320 number.
So it cant have those 320 cores (that is my understanding of reading this, maybe its wrong?)

the 352 gflop number you quote comes from:
320 stream proccessors (cores) x 2 x 550mhz = 352,000 flops (352 gflops).

But we "know" thanks to BG from neogaf that it uses VLIW5.
Which means that 320 stream proccessors isnt TRUE! (read blu's comment at the top)
So all those sites saying its 352 gflop are wrong.


I have looked through the last few pages on a 238+ page long thread on neogaf looking for some way to prove this. Theres probably some better than what I found but... yeah that ll take some time to look through.

If you feel up to it:
http://www.neogaf.com/forum/showthread.php?t=511628&page=238

 

Buttom line:

Eggs heads on Neogaf all agree its actually 160 stream proccessors (not 320), and that it thus only has 176 Gflops.

I believe them.

 

edit:

extra:

 

Supposedly the red ones are the ALUs (20 steam processors each) and the blue's the TMU.

It matchs up (from what I understand). 

20/5 = 4.

8 ALUs of 20 steam proccessors = 160

160 "cores" running 550mhz =  160 x 2 x 550 = 176,000 (176 Gflops)

Are you people mad? 3x-4x as powerful as Wii U is bad? You do know that it's essentially going to be a handheld, right? For me it's pretty amazing!

If Zelda Breath of the wild is the best they can create( wich it sure as hell wont be) then I and alot of Nintendo fans will be happy campers.

Starting to get tired of all this extreme power bulls**t that some of you in this thread spew out... I don't need it, I use my PC for that and so do alot of people.

I highly doubt Wii U is 176 gflops, it wouldn't be able to top 360 and PS3 graphics if it was 176, because 360 and PS3 were both 240 gflops. Multiple sources have it listed at 352 gflops and actual game performance seems to back that up.

Newer architecture.  Flops =/= flops.

Also bottlenecks, maybe the Wii U has area's its stronger in than the PS3 or Xb360, which means its 176 Gflops make its equal to the other two.

There's no point arguing with people who insist it's 320 SPs...way, way back on GAF there was talk about wavefronts (from leaked dev docs, IIRC) in WiiU's GPU and they came to conclusion it's only 160 SPs (plus TEVs from Wii, again, IIRC). With all other things pointing toward it as well, it really surprises me that so many people still stick to 352GFLOPS mantra.
