It would be VERY interesting if PS4 had a new AMD Gpu + old RSX. The RSX could be used for ps3 emulation, but maybe also for Physx-like technology.

As for the BC problem it doesn't elimated BC but makes it harder. If you remeber Xbox/360 BC was spotty, some games were not able to play, this is because of the optimised coding that used nVidia's propritary code (machine code). And they had to make the emulator work around it; the more optimized the game's engine made was, the harder it was to make work arounds in the emulator.

I don't remember but that is one of the reasons why they went through the trouble of offering the game online because they changed the engine, that contained the problematic codeing, instead of continuing to try to work around the machine code.

I doubt they will have an extra chip(s) on the PS4 since they will still have to pay nVidia for the use of it and paying two different companies for GPU's is a little steep and not that great of a business model.

Not necessarily. Xbox 1 was Nvidia, 360 is AMD, yet it is still backwards compatible with a lot of Xbox 1 games.

The 8th Generation of consoles is coming into motion. Everything is going according to plan.

Heh.

Hehehe...

MWAHAHAHA!

The Playstation 4 should just be a Blu-ray player. Sony should get out of console gaming.

PCs have AMD and Nvidia cards and the same game work on both... a emulator can handle this change with no problems... the real issue here is the CPU, because the CELL has a very specific architecture and that could be very difficult to emulate on a more traditional CPU.

There is a slight difference in making a game for a PC and a console. PC developers tend to rely on DirectX/OpenGL a little more because they default to the generic drivers on the OS. Though there are times that a developer will make its games to work better on certin manufacture's cards this is done by having modules that can switch depending on what card is being used. (Usually through the use of money hats on the manufacture's part. ;) The better proformance is done by using more machine code in the module that is used when the game detects the card (series) by that manufacture. (In this case machine code=the GPU's specialize extensions (it's assembly code))

With a console developers use a lot more machine code in optimizing their engines, especially as time goes one to squeaze more power out of them. This is why some games refused to work with the 360's emulator they used a lot of nVidia's propritary machine code. The emulator was made to try and by pass this as much as possible but for some games it was impossible to get it to work. So Microsoft used an engine they had already made for the 360 and did an engine swap out to offer their older  games online, especially ones that they couldn't get to work with the emulation.

Damn, you took my next thread title.

I guess that rumour that was floating around last E3 was correct and AMD has picked up the contract for all 3 consoles.
It makes sense considering how big hot and power hungry Nvidia GPUs have been lately terrible for a console.

Playstation console gaming is doomed if there isn't BC for next gen....C'mon how many of us would be playing ultra HD remastered versions of current games?...it wouldn't live up to the expectations howsoever. Btw to be on topic, with AMD lets hope the legendary John Carmack doesn't bull crap anymore about limitations.
