Well the rumor is the Wii U is running an AMD 770 GPU, and it looks like those rumors might be absolutely true.
A stroll over to AMD website will show a list of all the HD cards they have right now. You can look at the specifications of each card, and there's a very consistent rundown of each card......except the 700 series (excluding the 790). It doesn't show how much RAM is in the card or the Engine Clock for the 700 series, but the information can be found on EVERY other card series.
Hum, sounds fishy.
There are 3 cards in the 700 series. The lower end 750, the mid tier 770, and the high end 790. From the looks of the three it seems Nintendo is deciding on whether they should go with the 750 or 770. One thing to notice is that these cards support DX11, so the Wii U may very well sport some high end graphics if the consoles CPU, Memory, and HDD are as capable as the GPU.
What do you guys think? Is the 700 series enough?
To me it's more than enough with what Nintendo plans to do with it, and for Nintendo's franchises. Although the GPU is already a generation behind (actually 2, but the 900 series is way too much right now), and it's age is going to show even more by the time the console actually launches. Also with PC upgrading each year and a PS4 and Nextbox rolling out not to far from it's release Nintendo is going to have a hard time trying to keep the 3rd party support that it seems like it's going to have at least early on. But as shown with the Wii all that doesn't matter. Nintendo is trying to carve out their own little world, and more than likely 3rd games will make their way to the Wii U thanks to a similar interface as the 3DS and PS Vita. The GPU is also enough, because Nintendo doesn't have any franchise that really need to push the graphical barrier except maybe Zelda (as it was demonstrated) and Metorid, everything else not so much. What Nintendo games would benefit most from with this new GPU is allowing game developers to make larger game worlds for better exploration (will Pokefan finally get their POkemon MMO?).
But this brings me to my thought. How much are these consoles going to cost. The 700 series GPU retails for around $150 on AMD's website, but a quick peak at wholesale sites has the GPU listed for just over $100 (750 = $105, 770 = $120). Either way that's expensive considering Nintendo standards, so a $250 Wii U is out the Wii-ndow (get it, oh well). A $250 price for the Wii U was gone as soon as Nintendo decided to sell a $250 3DS (which I still don't get to this day, it should be $199 at the most, and it's not like $50 is that big of a deal, but $250 is an ugly number to look at for what is practically considered a children's toy). My guess is this thing is going to be at least $349 upon release which based off what it has, $349 isn't as bad as it may seem, but $400 is too much (again with the $50 difference). Once again this leads me to a bigger question.
What kind of GPU is the PS4 and Nextbox going to use, and how much are those consoles going to cost. A $600 console would be doom for either Sony or MS, and they're going to try their best to prevent it. But if they really want to leap forward like they did with the previous generation they're going to have to use 900 series card with the lowest being priced at over $200 and the highest reaching almost $800 (4GB version), and I don't even want to think what the rumored 7000 series is going to cost O_o
(Just in case you don't know they are on the 6000 series which means the Big N is using a 6770/6750).
So it's safe to say we won't be seeing a PS4 or Nextbox until Nov. 2012 at the earliest, but more than likely 2013 no later than 2014. And if they come out in 2013 then they should be around the $400 - $500 price range, but should be sporting a fairly powerful GPU that will be a generation behind :) by that time, so is it really that much different from the Wii U whose GPU will probably be 4 generation behind even the the console would only be 1 year old......nevermind that. Just enjoy what you get.
