See http://www.intel.com/performance/server/xeon/intspd.htm
In particular, look at:
  - Server benchmarks > Integer speed
  - Server benchmarks > Floating point speed
The blurb for SPECint_base2000 and SPECfp_base2000 states
  "System speed is measured by running single copy of the benchmark 
   which is an indication of the performance of single-threaded application"

I haven't actually tested a 51xx-series Xeon, and I too would like 
results from someone who has.
