Tim integrušama je najveći problem memory bandwidth. Da bi imali te PS4 performanse jednostavno moraju koristiti HBM, a što još nije službeno potvrđeno. Ako se krene spominjati da je klasični apu koji bi koristio ddr4 zaboravite na te performanse, bit će tek toliko da bude najjača igpu do sada (a onako bi trebala biti cca 3 put jača od sada najjačih igpu)
EDIT
International Solid State Circuits Conference (
ISSCC)
Citiraj:
In a separate paper, AMD said its upcoming Zen x86 core fits into a 10 percent smaller die area than Intel’s currently shipping second-generation 14nm processor. Analysts and even Intel engineers in the session said the Zen core is clearly competitive though many confidential variables will determine whether the die advantage translates into lower cost for AMD.
The paper detailed techniques AMD used to reduce switching capacitance by 15 percent compared to its existing chips. For example, Zen marked AMD’s first use of a metal-insulator-metal capacitor which helped lower operating voltages and provide greater per-core voltage and frequency control.
Engineers tracked on a weekly basis power benchmarks on high activity regions for more than a year to reduce switching capacitance. The company now has two eight-core designs running with simultaneous multithreading at 3.4 GHz.

Izgleda da je AMD fakat uspio male jezgre napraviti (manje od intelovih, na manje naprednom proizvodnom procesu). Nama userima možda i nije neki važan info, ali bi moglo biti važno AMD-u ako bi značilo manje troškove proizvodnje, odnosno veću zaradu.
