For the record, this guy said that Sega would release Dreamcast 2. Never happened.
And about the PS4 processor, he says IBM Power7 which sounds unlikely. This processor is not a lot more powerful than any other. I just has a huge cache and is very easy to parallelize which sounds useless for a game console.
I think it's bullshit...

the Dreamcast 2 is coming damit stop lying.
why don't you think the Power7 CPUs will be not a lot more powerful than other CPUs IBM have demoed 8 cored Power7 chips running at 5Ghz (4Ghz would be the highist that would be used in the PS4) and it is capable of performing 4 operations per cycle. even 3 core variants would be over 10X more powerful than the CELL in the PS3 at floating point calcs, and that is what the CELL was designed to do and it was better at it than any other CPU of it's time. in other types of procesing the power7 should be upto 20X better than the CELL as it's a much more well rounded achitecture and much simpeler than the CELL to develop for. Sony thought that the CELL would be the wave of the future and take over the computing world but it had a lot of problems and CPU architecture has moved on some inovations will be used but not many.

Well, in raw power, the CELL is more powerful.
In terms of ease to program, the Power7 is probably easier because you don't have to deal with SPUs but once again, what really makes the Power7 chip great in the global shared memory space. Something that the PS4 won't ever care about.
The processor of the PS4 could be based on the Power7 architecture, but probably with a LOT smaller cache and without support of global shared memory space.
If that's the case, it's not such an impressive CPU anyway. I like Power processor for their clean instruction set and I would be happy if they go done this way but once again, that's not a major step in the CPU area.
