AMD claims its core as modular. They could mod their "modular" architecture in order to fit Sony's requirement maybe.

Anyway, if there is no customized core, I would bet it is Steamroller-driven. As you can see, the first iteration of GCN APU is using Steamroller core. But I won't think that console designs will be the same as AMD's APU. The software stack is built from zero and they should have planned some unique features which require some special hardware blocks. Let's say... tile-based rendering with a big piece of eDRAM for less main memory bandwidth expense. It is commonly seen on console, isn't it?

Very slow

Which part is slow? CPU?

PS2: ~240mm^2 (250nm) CPU + ~280mm^2 (250nm) GPU
PS3: ~220mm^2 (90nm SOI) CPU + 260mm^@ (90nm) GPU

XBOX (short life): ~100mm^2 (180nm) CPU + ~140mm^2 (180nm) GPU
XBOX 360: ~180mm^2 (90nm SOI) CPU +  ...

你用呢個角度睇既話，都可以話未必會有既。Console 要 High-performance Graphics 嘛。如果 console platforms 無打算整件 heterogeneous computing SW stack 既話，咁繼續 dGPU + CPU，幾年後 shrink 做 SoC 係個合理既 ...

除非console lifespan縮短, 否則咁係合理估算

咁講再諗下，APU 既重點只係 communication overhead 短左... 當 Sony 唔打算用 eDRAM，睇翻 RSX 係 4 GDDR3 chips + 1 Logic Chip 既 MCM... Pitcairn- or Tahiti-class GPU 咪最少要 8-12 粒 GDDR5 既 MCM... 好似 ASUS Immensity 咁搞都得既

無可能

雖然話的確無乜可能，但係 RSX 無 eDRAM 啊。

PS4 will probably use silicon interposers with wide I/O memory (say a quad-channel 512-bit DDR data bus per memory chip)
sosad

Perhaps we will see such feature in APU products in 2014/15...
