PS4 GPU and APU: CrossFire?

[Aleschusta]

I was reading over internet that the PS4 will come with an AMD 8-core APU or similar, And a Radeon HD7850 comparable GPU (HD 7850: 1.76Tflops, PS4 GPU: 1.84Tflops). Since APU is a CPU and GPU combined in one chip, i wanted to know: PS4 will have one APU + GPU = CrossFire? Or the APU's gpu will be the HD7850? Also, PS4 will have 8GB GDDR5, so the PS4 GPU will need to be 512BIT, right?

That HD7850 comparable GPU is the APU's GPU portion. So far there is only 1 GPU in the PS4 as Sony have said. AMD went through some lengths to integrate as much as they can for Sony to lower production costs, so an APU approach makes sense.
