What the Industry is Saying...
"Microprocessor Report gave UltraSPARC III design the award for best workstation/server processor for year 2000 because, in addition to advanced internal features, it was designed expressly to enable large scale multiprocessing. You can see this reflected in the processor's on-chip memory controllers, data bus, interconnect design and a system approach that will enable more than 100 processors per box."

"Information technology (IT) managers must balance their desire for new, higher performance technologies with their need to preserve investments in already-installed hardware and software infrastructures. The UltraSPARC III's ability to run second generation UltraSPARC II software at full speed allows organizations to add UltraSPARC III-based systems to existing environments without any compromise to the integrity of the overall installation."

"Workstation and server processors, such as the UltraSPARC III devices, are clearly different than their embedded and PC cousins. In this market space, clock speed is not important, only total system throughput. With its powerful CPU core, direct memory interface, and high-bandwidth system bus, the UltraSPARC III processor delivers the performance, scalability, and reliability needed by demanding engineering and enterprise applications."
