The
UltraSparc III is the
second-generation 64-bit processor put out by
Sun. It is supposed to be 5 times faster than the UltraSparc II, and it can automatically
scale to systems with hundreds of processors. The
CPU is completely backwards-compatable with
software written for earlier versions.
The UltraSparc III employs 29 million transistors, an 8Mb level-2 cache, and allows scalable shared memory and mixed-speed CPUs in a single system.
