@Black_Pander It's highly probable that they will go with a 8-12 core processor especially if they use an IBM processor. Yes, graphics are important but the CPU is equally as important. Contrary to rumors, I think they will go with a modified 7950 or 7970, because they are planning on a 6-10yrs lifespan for the system and that's the standard of GPU required to run the Unreal 4 engine.

@Four_down_18 There needs to be some form of local storage.

@liam82517 That’s what they said about the RSX. BTW those cards aren't sufficient to utilize the full potential of the Unreal 4 Engine and the PS4 has to be powerful enough to live out its 6-10yrs lifespan.

@goldenboot76 That's for a PC.

I’m speculating that the Xbox720 will have:

1. A modified (8-12 cores) IBM Power7+ or AMD processor with APU features.

2. A custom GPU chip similar in specs/design to the AMD HD 7950.

3. 6-8 GB unified memory.

4. 500GB HDD and a Blu-Ray drive.

@RetroSEAL No, it’s what I’m expecting from the PS4. Yes people are going to say those components will cost over a $1000, but they are sold to Sony for far less. I’m expect initially it will cost somewhere between $500-$600+ and that's far less than the PS3 original manufacturing cost.

1. A modified 12 core IBM Power8 (or Cell processor) with enhanced APU features (Accelerators).

2. A custom GPU chip similar in specs/design to the Nvidia GTX 680. A modified (overclocked) 670 GTX would be good as it has similar graphics output to a 680GTX but cost less.

3. 2GB video memory and 4GB (XDR2) high speed main memory.

4. 500GB HDD and 8x Blu-Ray drive with BDXL support.

5. Wifi N (or AC), Bluetooth 4.0 and 2 USB 3.0 ports.

6. A $399 end-user price tag. (Single SKU like the PS2).

Those are the results of the original PS3 slim (45nm Cell CPU| 65nm RSX GPU) the newer model (45nm Cell CPU| 40nm RSX GPU) uses on average 18% less than that one.
