Moto's 7457, 7447 G4s now shipping
By ron carlson, Insanely Great Mac

These are low-power chips designed for embedded apps
Motorola has announced availability of the newest and fastest members of the company's
G4 family of PowerPC processors, the MPC7457 and MPC7447. These chips run at speeds up
to 1.3GHz, making them the highest performing G4 host processors available for
embedded applications.
The MPC7457 and MPC7447 can run at 1GHz while consuming less than 10 Watts, making
them ideal for high-performance, power dissipation-sensitive applications, such as
network control plane processing.
The MPC7457 and MPC7447 provide industry-leading 32-bit RISC performance in concert
with highly efficient power consumption across virtually all clock speeds. These
newest PowerPC processors offer OEMs a "best-in-class solution" for a wide range of
apps, including high-performance network infrastructure, telecommunications switching
equipment and state-of-the art medical and industrial imaging systems.
Offered in a 483-pin ceramic ball grid array (CBGA) package, the MPC7457 processor is
footprint-compatible with Moto's award-winning MPC7455, providing an easy migration
path for OEMs. The MPC7457 is designed to reach speeds of 1.3 GHz with a core voltage
of 1.3V and includes 512KB of on-chip L2 cache (a 2X increase over the MPC7455's L2
cache), with support for up to 2MB of backside L3 cache.
The MPC7447 processor delivers the same performance and features as the MPC7457,
except that it does not provide backside L3 cache support.
Both of these new devices are manufactured using Moto's 0.13-micron HiPerMOS
silicon-on-insulator (SOI) copper interconnect process technology, enabling the
processors to deliver superior performance over bulk CMOS technology.
Editor's note: The 7455, which is one of the chips used in current G4 PowerBooks, and
the new 7457 are pin-compatible. This information taken together with the phrase "with
speeds up to 1.3GHz" and it's a fairly safe bet that we know what the next PowerBook
speed bump will be.
On the other hand, when was the last time Moto announced Mac-ready chips before Apple?
