"up to 16 helpings of Cortex-A57 clocked at 2GHz"

Going by the name of "Seattle" and scheduled for launch in the second
half of next year, it'll be built around ARM's 64-bit Cortex-A57 in
either 8- or 16-core configurations, which will likely be clocked at a
minimum of 2GHz. ...we're told that this design has the potential to
deliver 4x the performance of AMD's current Opteron X processors, with
improved compute-per-watt. ...[AMD will] use Seattle to up against
Intel's little Atoms, but will continue to sell its own x86 designs
for higher-power applications.
AMD announces its first 64-bit, 8- and 16-core, ARM-based server SoCs
New SoCs are Cortex-A57-based and are "expected to run at or greater
than 2GHz."

...today it announced the first major details for the new ARM-based
chips, which begin sampling in the first quarter of 2014 and shipping
later that year.
The new SoC, codenamed "Seattle," is based on ARM's upcoming
Cortex-A57 architecture, meaning that it will be fully 64-bit, just
like AMD's x86 processors. Seattle will support up to 128GB of RAM,
integrated ten gigabit Ethernet, and AMD's "Freedom Fabric" tech,
which groups low-power CPU cores together into clusters to feed them
with data from the network more efficiently. AMD expects the eight-
and 16-core SoCs to run at speeds of at least 2GHz.
AMD says that the ARM SoCs will offer two to four times the
performance of the just-announced x86-based low-power Opteron CPUs,
though this performance figure would appear to come from the boosted
core count (eight or 16 compared to four). Given that they have
similar clock speeds, then, it would appear that AMD is expecting the
Cortex-A57 architecture to perform as well as its "Jaguar" CPU
architecture while using less power overall.
