Just wondering... is the 7457 already shipping? I saw an interesting article just now, dating from June:
Note that the date in the press release is wrong -- it was June, not May.
Synergy Now Shipping 7457-powered Boards,
Breaking GHz-plus Speed Barriers
Synergy is first embedded SBC vendor to deploy ultra-fast PowerPC7457 G4 chips, giving OEM customers time-to-market advantages with validated, next-generation SBCs.
May 27, 2003/San Diego, CA Synergy Microsystems, Inc. (Synergy) announced today that it is now shipping evaluation SBCs with single or dual, PowerPC 7457 G4 processors that deliver 1.3-GHz speeds while using under 15W of power per processor. Company executives said the new class of fully certified boards - the first to break long-held cycle-speed barriers without requiring additional power or generating higher heat profiles - will enable a new generation of defense and industrial applications.
"We moved very quickly because we believe this new Motorola chip is a break-through design," noted Thomas Powell, Synergys CEO. "It provides almost 12 GFLOPS of performance, yet actually lowers the power drain. When running at 1 GHz, it dissipates less than 10 watts - which falls well beneath the threshold for embedded power-sensitive designs."
