DISCLAIMER -- I'm not a Sun employee but a very very satisfied customer.
This is a classic FUD-sample that misguides potential users. The Niagara line is known as the throughput-computing platform because of the multi-core architecture. Each core is not a metal-burning heat-generating monstrosity but moderately well performing (1 - 1.4Ghz). The advantage of running apps in this platform is those immensely multi-threaded ones, which can take advantage of the 4 or 8 threads that each core can handle (so instead of running 1 thread super-fast, you run 32 or 64 threads moderately fast). Sure, single-threaded performance is not comparable to the x86/x64 or other sparc procs, but end-result is more computing done faster.
It is very important to choose a right application to do the comparison (there are plenty of benchmarks out there that prove that the Niagara-based systems outperform comparable systems when the workload is appropriate. These are not "one size fits all" solutions, they are specific and highly effective solutions to specific problems.
