personally I hope they use a 7770 or higher - cards with that GPU begin at ~95€ at retail right now so that shouldn't be too costly for console manufacturers

A 7770 would be a nice fit IMHO, not just in terms of performance but features and power consumption too.
Microsoft/Sony would be buying the chips themselves (Not packaged on a PCB with large exotic coolers.) and in bulk, so they would get it far cheaper than $95.

Yea, that's what I meant. I guess I didn't phrase that too well.

Rumours are just fake news to me. Every week people talk about new rumours...

master zero... this is chinese to me... could you please translate this in english? and how tdoes it compare to wiiu if true?

You may laugh and I understand if you wish to defend Sony here, but the Operating systems & applications on all my Sony's gadgets is slow & bulky in respects to the type of hardware that they use. They never really take advantage of all their hardware. I'm talking about my Sony Erricsson interface, my Sony Blu-ray player interface (not PS3), my PS3 applications, my PSP games & applications, PSV applications. I feel that they don't provide the consumer with same amount of software quality that they try to give them with the hardware (I'm not talking about games here). I could go into detail with each one, but I'm not going to. If you own a Sony product, compare it to more popular ones and I'm sure you will notice why Sony lost their grip on the market.

Its like they try to sell you a car with a shinny beautiful exterior thats great, but when you get inside it, you realize that its missing many of the important perks that most popular commuters have. It's annoying.

I'm talking about my exprience with AMD/ ATI cards. When one plays games like Never Winter Nights 2 and realizes that it was optimized for Nvidia cards in mind, it sorta sucks that I can't turn on the shadows above low in the game because the FPS drop to 10-15. I still have my AMD card, and I primarly buy AMD cards, I'm not trying to bash AMD. What I am trying to say is that when a company has a good deal of influence in the market, they sometimes make partnerships with developers where the code is optimized for their products. If you don't believe me just take a look at game ports, not all of them a great.

You said, "Also, the reason why a super powerfull PC can't emulate a PS2 100% perfectly is simple. - It's not a PS2."

Good! That was exactly my point. PS2 game software was optimized for the PS2 in mind. A PC can't do it as well. That was my point. And to add to that, I'm going to argue that Sony and Microsoft don't need to have a high level GPU. They just need one that when optimized can do full 1080p with direct X with a hint of anti aliasing (maybe some Tessellation) at 45-60fps. Why pay for more? Please remember that they only need to meet 1080p screens; 2k & 4K screens are years aways before they become affordable alternative. They would be shooting themselves in the face if they try to place anything higher on their console because of the HDTV screen bottle neck.

Well. If they only wanted to do 1080P then the Xbox 1 GPU could do it, with included Anti-Aliasing. - Just don't expect amazing lighting, high quality textures, high polygon models and other effects, but it could still do it just as the PC equivalent could do it, that is... If you're only worried about resolution. (There is allot more to graphics rendering than just the resolution.)

The problem is... As developers start pushing a relatively low-end chip that's in the realm of integrated graphics performance-wise then they need to make sacrifices, one of those sacrifices this generation was in the form of resolution and framerate.
If they go with low-end chips then they will do the same thing, just much sooner because they will utilise the extra processing to make the game look nicer.
If they have allot of graphics processing head room, then you probably could enjoy gaming at 1080P@60fps for a couple of years.

Now if they dropped in a high-end card? Not only do they not suffer from massive performance hits when loaded with super fast memory when running higher resolutions, but they could handle allot of effects at once that will make your eyeballs have an orgasm.

Your forgetting something, the PS4 will be using an A10 apu and the 7670 gpu. The A10 contains a 4 core cpu PLUS a gpu on one chip, which will be able to work together with the 7670, in effect it will have 2 graphics cards.

Well I hope the 720/8 gets the 8800 and the 8GB Ram rumor.
