This one falls into the reasons-we-bought-ATI column: future AMD CPU architectures will employ higher levels of design automation and new high density cell libraries, both heavily influenced by AMD’s GPU group. Automated place and route is already commonplace in AMD CPU designs, but AMD is going even further with this approach.
The methodology comes from AMD’s work in designing graphics cores, and we’ve already seen some of it used in AMD’s ‘cat cores (e.g. Bobcat). As an example, AMD demonstrated a 30% reduction in area and power consumption when these new automated procedures with high density libraries were applied to a 32nm Bulldozer FPU:
The power savings comes from not having to route clocks and signals as far, while the area savings are a result of the computer automated transistor placement/routing and higher density gate/logic libraries.
The tradeoff is peak frequency. These heavily automated designs won’t be able to clock as high as the older hand drawn designs. AMD believes the sacrifice is worth it however because in power constrained environments (e.g. a notebook) you won’t hit max frequency regardless, and you’ll instead see a 15 - 30% energy reduction per operation. AMD equates this with the power savings you’d get from a full process node improvement.
We won’t see these new libraries and automated designs in Steamroller, but rather its successor in 2014: Excavator.

Vykon v int porastie, FPU, ale nevyzera to ruzovo. Ja to vidim asi az na Excavator, ale mozno tam bude len 1Fmac a 1MMX
Na druhu stranu tieto slajdy pochadzaju z legendarne babrackeho AMD marketingu, takze ja to vidim este na zopar odlisnych prezentacii ved do uvedenia maju casu dost.

spíš tam bude jedna 256 bit FMAC se sdílenou MMX unit
\\ Leda že by tu FPU konečně nahradili nějakým GCN2 SIMD ekvivalentem ....
