In 2004 Freescale announced a new high performance core. Not much was known about it. It would be a multi core, multithreaded design using CoreNet technology, shared with the e500mc core. It would be a three issue core with double precisionFPU. Roadmaps showed a target frequency of 3+ GHz, manufactured on a 32 nm process and that the chips would be named on a MPC87xx scheme.
Freescale eventually released the e5500 core but it was not the same core even though they are very similarly speced.
