New UltraSPARC T2 CPU doubles threads from 32 to 64

As more than one energy expert has noted, efficiency plays an enormous part in power consumption, regardless of the context.

Sun’s three-family server strategy fits into this thinking quite well. Based on three separate chip sets designed for particular workloads, use of each member of the family for particular situations can go a long way in reducing power consumption while boosting computational performance.

Sun Fire CoolThreads servers based on UltraSPARC T1 chip multithreading (CMT) processors are ideally suited for massive transactional throughput — making them a perfect fit for managing large numbers of Web-based transactions. In areas that require the industry-standard x86 chip and demand both multithreaded and high floating point performance, AMD Opteron processor-based Sun Fire x64 servers might prove a better choice. And for heavy-duty database applications where single-threaded performance trumps throughput, UltraSPARC IV+-based Sun Enterprise servers deliver the necessary horsepower.
