GT 5.5? I hope not.
Lets face facts. PS3 is an obselete piece of kit.
1 3.2GHZ Power 5 CPU and 6SPUs that are non independent. All instructions are fed through the Power 5 core.
It has a crap (by2013s standard) GPU, an Nvidia 7800GTX GPU and split memory pools of 256MB XDR@3.2ghz and 256MB DDR3.
Its a mess, YET, Guerilla Games, makers of Killzone series ported their PS3 engine unto PS4. They had a press conferance today detailing it.
The PS4 has 8 Cores, each between 1.6GHz and 2GHz.
8GB GDDR5 ram at 176gb/s
and a HD7850 GPU.
What they did was basically emulate the PS3 instruction set on PS4 by having 6SPUs emulate by the 6CPU cores on PS4 to distribute the CPU loads. They used the remaining two PS4 CPU's to emulate the POWER PC Core, and then ofloaded the rest to the GPU.
SO, why didnt PD announce GT6 being cross-gen if its that simple to do????
The PS4 Graphics Card is literally 10× the power of PS3s AND, there is a unified pool of memory.
I am disappointed. I really am.
First GT I may skip.........
