So if it is 8xxx, which I find odd because I think even Yoshida was talking 7850 in an interview I translated.
"GPU core architecture "Graphics Core Next" new generation of AMD (hereinafter, GCN) GPU core that has been found to be employed. I used to adopt an architecture called "Jaguar" CPU core (or Jaguar Jaguar), for here will be described later.
Well, GCN, the architecture that is employed but has been known GPU series codenamed "Southern Islands" as development (Southern Island), the Radeon HD 7000. Sony Computer Entertainment Inc. (hereinafter, SCE), which has been APU of PS4 is equipped with a "compute unit of the group 18", in the GCN, the compute unit "GCN Compute Unit" is a scalar floating-point processor 32bit (= Shader because the core) "Stream Processor" (hereinafter, four pairs are contained as a set group of 16 SP), the entire APU of PS4, will be equipped with a SP of group 16 × 4 × 18 = 1152.
Belongs to the 7800 series Radeon HD "Radeon HD 7850" number of 1152 based on this, it is calculated that the middle "Radeon HD 7870 GHz Edition" and the group (1024) group (1280).

In addition, there is the spec was released, and has the processing performance of 1.84 TFLOPS, assumption that group 1152 Number of SP, in the GCN architecture is the fact that SP that can perform (2 Ops) summing the product one on one clock Given, from the formula of "(1.84 TFLOPS ÷ 2) ÷ 1152", also derivable operation clock of about 800MHz. Close to the same Radeon HD 7870 GHz Edition 1000MHz and 860MHz rated for Radeon HD 7850, It's a number with a sense of reality."
Before the PS3 everyone was nice to me :(
