會唔會係 第3 代既APU ?!

I am not sure

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

Maybe just Piledriver  + HD7770

我都仲係信佢用4C Cell2多啲。

Very slow

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?

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

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?

除非console lifespan縮短, 否則咁係合理估算
