According to a benchmark, Sun's Niagara processor is over 4 times faster at serving dynamic PHP pages than a dual Xeon server. "We did real production benchmarks using different servers. Servers were put into production behind load-balancers, then weights on load-balancers were changed so we got highest number of dynamic PHP requests per second. It must sustain that number of requests for some time and no drops or request queue were allowed. With static requests numbers for Opteron and T2000 were even better but we are mostly interested in dynamic pages."

Making use of Intel's SMT implementation is not like having two processor cores. Comparing a dual-core Opteron to a single-core Pentium 4 with HTT might have some informative value but it is not a "fair" comparison. One approach attempts to schedule more work on the same number of functional units, while the other schedules work on twice the number of functional units.
That doesn't mean that a comparison betweena dual Xeon and the T2000 is necessarily unfair. Each core in the Xeon is considerably more complex than one core in the Niagara. The question you should ask yourself, is if instead the benchmark were stressing the strength of the Xeon and weaknesses of the T2000, if people would come out and say "YEAH TWO CORES SMOKED EIGHT OF SUN'S!" Sometimes people treat computers like sporting teams.
