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:

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)

"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.

No one actually cares about specs, they care about games and NX games will look near identical to PS4 games unless they got a decent CPU to double the FPS which would likely negate their price advantage over the PS4.

That would put it at at least Xbox One level, possibly between Xbox One and PS4, since Nvidia flops are better than AMD flops usually. 352 x 3 = 1056 gflops, 352 x 4 = 1,408 gflops. 

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.

Where they go wrong in their assumptions is all of the unaccounted for parts of the chip which no one on NeoGaf could tell what they did, besides being fixed function. If you believe them to be them to be fixed functions then how do you just throw those processing abilities away and not include them in the theoretical number?

I believe they said 35%- 40% of the chip they can't iron down exactly what it does, but they know the latte is more efficient than the previous 7th generation consoles... This was the main reason why the 176 Gflops was always being challenged.

So your saying why give a weaker console graphics, more cashe? and memory bandwidth?

I can understand that. But my reply is just maybe nintendo puts weight on differnt design philosophies than MS.

They make these machines based on what they need. Maybe some hardware engineer told them to give it alot of edram, because they would need it for a new mario game?

Also All flops arnt equal. Just like with the mhz of a cpu, a intel cpu at the same mhz is usually faster than the amd one.

It varies from architecture to architecture.

Everyone says 352 Gflops....... except the people that know that it is not that.

I explained to you why it cannot be 352.

320 cores doesnt work with VLIW5.

It just means alot of people are wrong.

And lastly..... theres more to being strong at graphics than just how many Flops of compute power a graphics card has.

The PS2 sold ~81.89 Million units after it had a price cut to $149 (more than half it's sales), so it was cheap in its own right.  It also had a lot of games and capabilities to satisfy most.  That generation likely had the least multi-console owners just by looking at the dominance of the PS2, but when both the Wii and PS3/X360 succeeded multi-console ownership probably increased a lot too.

The introduction of intermittent consoles like PS4 pro and looming Scorpio is likely shake up the traditional console cycle anyways and might influence a change in buying patterns.  If the NX can somehow entice people with something compelling when people are looking at new hardware then they might have a chance.

You are entirely correct.

The Wii U is based on the VLIW 5 architecture. (Very Long Instruction Word - 5 Way.)

But because the GPU is far more efficient, it is also far more capable than what the Gflop number implies, the Wii U can do more modern effects and lots more of them at any one time than the Playstation 3 and Xbox 360... And the games back that up.

If the NX is using Tegra... Then it is likely using Denver. And possibly Denver 2. The NX could give the Playstation 4/Xbox One a good run for it's money in CPU performance... As the latest Tegra uses a Big.Super CPU design. - The real kicker is if Nintendo has deviated from that.
We just have to wait and see.

No. nVidia's flops aren't any better than AMD's flops.
There is just so much more to a GPU's performance that people are associating a chips complete performance to flops and then thinking that nVidia's flops are magically better than AMD's, when that is entirely inaccurate.

You can doubt it all you wan't, it won't change anything. There is more to performance than flops.

The Wii U has a ton of cache and memory to hide bandwidth and latency deficits.

Plus one of the largest issues developers had last generation was the lack of memory, especially towards the end of the generation.

Even so, the unaccounted parts of the chip doesn't change what we do know about the chip.

The unacconuted parts do not have any parts resembling other parts of the chip, so it's likely logic, fixed function and specialized units and spare area.

The 5550 variant disabled one shader engine, so had only 320 stream processors (4 engines, 80 VLIW-5 units (in) each).

Wiiu have customised gpgpu...  You can't say VLIW 5  is a raison to don't have 320 cores... 

I dont know how to convince you, so I wont try too anymore.

There has to be someone better suited to this than me to explain it.

Neogaf guys say 176 Gflops, it is that, I trust those guys.

GAF have also been behind a number of the NX rumours so that's not saying much.

How you dare to say that from all mighty Neogaf?
