Sun Studio 12 patch performance improvements quantified for Core2Duo
My previous blog pointed at the first available Sun Studio patch. It mentioned that there were performance improvements for the Core2Duo architecture beyond what was in the released product.
This one quantifies the improvements we're seeing on SPECfp2000 (52%) and SPECfp2006 (34%). There are small improvements (0-3%) on SPECint2006  and 1-4% on SPECint2000 as well, but they are not as noteworthy. The system used here is a whitebox, 2 CPU, 4core 2.66GHz x5355 based system with 4GB memory. This run was a purely a comparative run and not done for a SPEC submission, so these arent official SPEC numbers (they are not numbers, anyway) but SPEC estimates, in that regard.

Benchmark: SPECfp 2000	%Change (over Studio12 FCS)
wupwise	30.3
swim	83.23
mgrid	39.10
applu	80.92
mesa	3.52
galgel	172.86
art	130.83
equake	14.05
facerec	2.44
ammp	65.74
lucas	13.86
fma3d	36.98
sixtrack	96.94
apsi	50.50
Overall Geo Mean	51.99

Benchmark: SPECfp 2006	%Change over Studio 12 FCS
410.bwaves	10.05
416.gamess	50.26
433.milc	12.99
434.zeusmp	50.34
435.gromacs	21.24
436.cactusADM	57.82
437.leslie3d	32.10
444.namd	62.20
447.dealII	9.00
450.soplex	4.58
453.povray	13.38
454.calculix	166.38
459.GemsFDTD	24.79
465.tonto	41.75
470.lbm	12.27
481.wrf	3.00
482.sphinx3	18.75
Overall Geo Mean	34.55

Now, you know, why I recommended that if you're using Sun Studio 12 for Woodcrest, Clovertown (Core2Duo) systems, then you MUST get the new patch.
