Quoting IBM "The target operating frequency is 500+ MHz, estimated peformance is 30+ SPECint95, 70+ SPECfp95. The POWER3 processor will be at the heart of a 4096-processor RS/6000 SP super computer. When the system is upgraded with POWER3 processors in 1998, it will deliver a whopping 3.0 teraFLOPS." A recent BYTE article discussed the POWER3. I was impressed by the aggregate cache and memory bandwidth. For example, the chip has a 256-bit L2 cache bus (compared to 64-bit for PCs and Macs). See http://www.ssd.sscc.ru/library/cpu/ for good info on new chips.
