BD-based，你唔會想要

in fact too slow for this application
unless sony shorten the 10-year cycle

Maybe just Piledriver  + HD7770

Very slow

Which part is slow? CPU?

both

GPU: at least Tahiti / Kepler / Sea Island derivatives
CPU: at least 4GHz+ Bulldozer / 3GHz+ SB / IVB or equivalent class with 6+ threads

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 ...

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 + ~180mm^2 (90nm) GPU

你話會唔會有<350mm^2的PS4 / new xbox CPU+GPU combo?

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 AS ...

主要係cost down
