I know very little about imaging editing and I'm just using the selection tool in paint here so forgive me if I've got something wrong
But for me a Brazos block is measuring 124,614 pixels, vs 107,328 pixels for a Latte block:
Measuring just the shader logic in the same way comes out at about 74,586 vs 67,878:
When you take into account that Brazo is DX11 and SM5 while Latte's ALUs don't have the extra logic required for those things, it makes sense that Latte's ALUs would quite a bit smaller as well. You COULD fit 320ALUs in that block, or 256ALUs + extra logic for TEV. You also have to take into account that to scale, the 40nm process is likely more dense than Brazo, especially the advance one we think they used here.
As for Beyond3D, there is obviously people in the thread driving the thought process to the lowest possible performance while reaching xenos or slightly above it.
http://www.beyond3d.com/content/articles/118 I think this speaks for itself. Pay a lot of attention to the first paragraph in the conclusion:
"To conclude this article, we would like to emphasize, once again, that as usual with modern day Nintendo, very little is officially known on the technical side of their new console entry. Therefore,
the speculation presented in this article is not to be mistaken with other more factual Beyond3D entries."
Speculation is hopefully (on beyond3d it almost always is or is called out) an educated guess based on known parameters.
The problem with Wii U, a lot of those parameters we work on are not known, but the best guess at the time. Beyond3D's early e3 conclusion was that Wii U's casing wasn't big enough to offer much graphical performance over 360s. Which is at best very foolish to assume since it could easily of been a 32nm part for the GPU and offer 640ALUs or more and still fit under the assumed at the time TDP of 100watts.
What I mean to say about all of this, is that Beyond 3D is a tool, the experts there might have a bit more insight than experts here, although Blu, Wsippel and others from this very thread have all heavily contributed to that thread even more than some of the Beyond 3D members who don't post here. I would not be so quick to dismiss claims made in this thread just because they were not posted in Beyond3D first. In fact this thread has continuously been referenced there with information, Wii U's CPU benchmarks come from blu posting here first iirc. I personally think this thread has done more useful speculation of Wii U hardware than beyond 3D's though this one goes off topic more often.
