The e600 core is virtually identical to the G4 core, but with enhancements to L2 cache and AltiVec implementation, and it is manufactured in 90nm technology. Software written for the MPC7447 and MPC7447A will run seamlessly on the MPC7448. MPC7448 can be a pin-for-pin compatible drop-in replacement for MPC7447A.
