argonaut writes "Ace's Hardware has an in-depth article on Niagara -- Sun's upcoming parallel server processor with 8 cores and 4 threads each. The article discusses the chip's radical architecture and what kind of performance can be expected from it in traditionally thread-heavy server applications like web hosting, databases, and other multi-user applications. Given the recent cancellation of the UltraSPARC V, it seems this is going to be Sun's new direction for its in-house CPU design efforts. Furthermore, both Intel and IBM are working on other highly parallel processors and AMD is expected to eventually introduce a dual-core Opteron. So, will more threads prop up Sun's performance?"
