ARM is boasting about performance and performance/Watt
advantages of A9 over first gen Atom.

Second gen Atom brings an integrated memory controller
to the table. A large part of the performance jump from
the K7 core to the K8 core for general scalar integer
workloads came from the change from FSB/northbridge
to IMC. This change will also significantly reduce active
power at the system level. As an example of this the
difference for SFF Atom desktops ("nettops") from first
to second gen is from 33W to 15W at the board level.
For mobile/handheld applications the benefit of going
from a FSB/northbridge architecture to SoC/IMC may be
even more substantial.

The second gen Atom is made in a low power process
that reduces transistor leakage current by several orders
of magnitude vs first gen. This will significantly reduce
power in idle and mixed power mode operations as well
as active power to a lessor extent.

Yeah, second gen Atom doesn't change the CPU uarch but
uncore and semi process technology changes likely mean
very substantial improvements in performance and major
reduction in both dynamic and static power consumption
at the system level.
