What is it with all the WiiU specs threads and PS3 fans coming in and flooding the threads with posts downplaying WiiU. Can't they go play their PS3s or post in some God of War of Last of Us-thread or something..? :s
Everybody and their grandma knows by now that you guys don't like WiiU and will probably never get one. We don't care. Get over it. -Nobody- is saying WiiU is an insane powerhouse, or that PS4/X720 won't be more powerful. Obviously. Get over yourselves. PS4/X720 will be -severely- underpowered compared to PCs as well.

Gosh, I don't see any PC fans going around flooding PS360 threads with countless posts of how sad those consoles' specs are, or having sigs touting the inferiority of said consoles compared to their obviously superior PCs.

 Bit sensitive, this if a internet forum for gaming discussion I fail to see what’s wrong with speculating the spec of a system a company has refused to show.

 

Nothing wrong with that. But there's a difference between what you're suggesting and what's happening on here. It's overkill.

neogaf and beyond3d are thinking it's 160 SP now and DF will run an article about Wii U being 160 sp or not.

Actually, during this time i did a little of research and found out a few things about the 160SPs theory.

 

First, let's say these 30% of unknown space in the GPU doesn't exist. Now, from my calculations, 30% of 156.21mm^2(Wii U total GPU die size) gives us 46.83mm^2, which is the size of the unknown space in Wii U's GPU based on the information we have. Combining this number with the size of the eDram module, which measures is 38.68mm^2, we get 70.81mm^2 free space for the actual GPU on the die.

 

Now, let's get a 160SPs Radeon GPU for die size comparisons. Radeon HD 6450 which has 160SPs,core clock of 750MHz and, ironically, is manufactured at TSMC's 40nm process, has a die size of 67mm^2, which fits inside the 70.81mm^2 on the Wii U. So, if we completely rule out the unknown space on the GPU, then, yes, we probably have a 160SPs Radeon HD 6450 downlocked on the Wii U. Actually, this GPU is quite a match with the Wii U, as it's TDP is only of 18W at 750MHz, which could be easily reduced by downclocking the GPU. And, based on the research i've done, only Radeon HD 69xx cards have the Double Precision extensions, so if Wii U's GPU is the HD 6450 we could rule out any possible way to increase SP density on the SIMD blocks from removing the DP extensions. However, there are still possibilities to increase SP density on SIMD blocks besides removing the DPs, so i can't confirm the GPU being a 160SP one nor a HD 6450 because there are still multiple factors that could change SP count similar die sizes.
