[QUOTE="ronvalencia"][QUOTE="PS3FanMan4Life"] PS4 will be using the Cell 2 processor, as well as an AMD powered dedicated GPU with over 1GB ram. The graphics processing power will be shared with the Cell 2 in order to boost dashboard load times, as well as all other non-ingame processes. It's complicated, but unfortunately i'm not allowed to say a whole lot more. PS3FanMan4Life
AMD GCN negates the need for SPUs. AMD GCN supports C++ on hardware and X86-64 pointers.
Yes, but to for the sake of continuity and sheer processing power, Sony will stick to the Cell 2 processor, which has been upgraded to make it slightly easier to program for, but they fully expect developers to be familiar with the difficulties, but the sweat it worth it to tap into the sheer power of the Cell."Sheer power of the Cell" gets destroyed by ATI Radeon X1900.
Games that directly use NVIDIA RSX's instruction set (via LibGCM) would be another problem for BC.
Again, you have haven't negated Rory Read's "Our semi-custom APUs already have a number of confidential high-volume design wins in place" statement.

On transistors packing skills
At 28nm process tech, 32 core CELL would have a chip size about 284 mm^2 and it only delivers 4 times over existing CELL.
~230 GFLOPs x 4 = 920 GFLOPS.
Based on CELL's 115 mm^2 @ 45 nm process tech, 28 nm version of CELL would have a chip size of 71 mm^2. Density of ~3.34 million transistors per mm^2.
With 45 nm process tech, IBM Power 7, has a chip size of 567 mm^2 (packing 1.2 billion transistors). Density of ~2.12 million transistors per mm^2
With 28 nm process tech, IBM Power 7, has a chip size of ~352.8 mm^2 (packing 1.2 billion transistors). Density of ~3.40 million transistors per mm^2
IBM is consistent with inferior transistors per mm^2 skills.
For comparisons
With 28nm process tech, AMD Radeon HD 7870 has a chip size of 212 mm^2 (packing 2.8 billion transistors) and delivers 2560 GFLOPS. Density of 13.2 billion transistors per mm^2.
With 28nm process tech, AMD Radeon HD 7970 GE has a chip size of 352 mm^2 (packing 4.313 billion transistors) and delivers 4300 GFLOPS. Density of 12.25 billion transistors per mm^2. Notice AMD improves transistors per mm^2 within the same generation. Radeon HD 78x0 carries the revised AMD GCN design. The next flagchip Radeon HD 8970 would carry the design improvements from Radeon HD 7870.
With 28nm process tech, NVIDIA Geforce GTX 680 has a chip size of 294 mm^2 (packing 3.54 billion transistors) and delivers 3090 GFLOPS. Density of 12.04 billion transistors per mm^2. NVIDIA plans release it's own flagchip Geforce GTX 780.
With 22nm process tech, Intel Ivybridge has a chip size of 160mm^2 (packing 1.4 billion transistors) . Density of 8.75 billion transistors per mm^2.
There's reason why IBM CELL based add-on card was blasted from the PC market.
