Sun Studio powers new Opteron Workstation to record SPEC INTrate and SPEC FP Sun recently introduced the so-called AM2 variant (the next-generation of AMD processors) of Sun Ultra40 Workstation. For details, see here. With this introduction, Sun also announced new World Records with this machine. I am particularly happy with this particular one (words from the product page, directly).
The Sun Ultra 40 M2 workstation, with two Dual-Core AMD Opteron model 2220SE processors, has reached a new milestone on the SPECint_rate2006 suite of the SPEC CPU2006 benchmark, by utilizing the most advanced features of Sun Studio 11 software and Solaris 10 OS.
Leading the x86 segment and surpassing competing workstations, the next-generation Sun Ultra 40 M2 workstation produced a SPECint_rate2006 result of 48.8. For a while now Woodcrest had retaken the SPEC INT lead held previously by AMD's Opteron chips. The performance of Woodcrest on SPEC CPU2000 has been particularly spectacular. So it is particularly pleasing to see that with CPU2006 INTrate, Sun has been able to reclaim the World Record here for the dual-core AMD Opteron model 2220SE processors. The rate measure is particularly important as we move into the dual- and quad-core world for the x86/x64 architecture machines.
In addition, Sun Ultra 40 Workstation continues to claim World Record performance for SPEC CPU 2000 FP with best numbers (Peak) of 3545 and a 4-core FPrate of 121. This beats the Woodcrest based numbers, handily, by about 40+%
The following table shows these comparisons:
SPEC CPU2006 INTrate (ratios, higher is better)

System	Description	#Threads	INTrate
Sun Ultra 40 M2	AMD 2220SE (dual-core 2.8GHz), 2CPU	4	48.4
	SuperMicroWoodcrest, Intel 5160 (dual-core 3.0GHz), 2 CPU	4	45.2
Dell Precision 380	Intel 3.73 GHz, Pentium Exteme Edition 965	4	23.1

SPEC CPU2000 FP(ratios, higher is better)

System	Description	#Threads	FPrate
Sun Ultra 40 M2	AMD 2220SE (dual-core 2.8GHz), 2CPU	2	121
Dell Precision 690	(Xeon 5160, 4cores, 2 chips, RHEL 4AS U3)	2	81.3
