PowerPC G4 copper

.2 micron 32-bit microprocessor
Future Motorola chip, aimed at the embedded market as well as the PC (including Apple Mac). Should go into production by the middle of 1999.
The G4 is the first PowerPC to feature Motorola's AltiVec graphic vector processing operations. Supports 512K to 2MB of backside L2 cache, connected via 64-bit or 128-bit buses. Multiple G4s can access each other's caches, offering much improved multi-processing performance.
Will offer 10-15 times the performance of the current PowerPC 750. Contains 10,500,000 transistors, consumes less than 8 Watts @ 400 MHz.
An information on the G4 could be found in articles "Motorola launches PowerPC G4" and "Second-stage PowerPC G4 details emerge" by Tony Smith, The Register.

PowerPC 620 64-bit RISC microprocessor

The PowerPC 620 microprocessor features a high bandwidth memory subsystem ideal for symmetric multiprocessing, transaction processing and numerically intensive computing. It is a superscalar design capable of issuing four instructions per clock cycle to six independent execution units. The PowerPC 620 microprocessor supports out-of-order execution with in-order instruction completion. L2 cache could be 1MB to 128MB in size. The target operating frequencies are 133, 180 and 200 MHz, estimated performance 8.0 SPECint95 and 10.0 SPECfp95 @ 200 MHz 4 MB L2 cache. Contains 7,000,000 transistors. Power demand is 40 Watts @ 200 MHz.
An informtion on 133 MHz PowerPC 620 could also be found at IBM "PowerPC 620 RISC Microprocessor" document.

PowerPC 750 (G3) .25 micron 32-bit RISC microprocessor
