The Intel chip, as benchmarked, is 2.1 GHz. The same design is available in 3.6 GHz, as of Q2 '12. We're comparing a top-clocked, circa 2013 SPARC to a 2012 Intel product running at 60% of the commercially available clock rate, and the SPARC comes up short.

I used this poor comparison because that was what was readily available in SPEC's published results for single-processor (SPECcpu) and parallel (SPECcpu_rate) benchmarks.
