From the Standard Performance Evaluation Corporation's web site :
CPU2006 is SPEC's next-generation, industry-standardized, CPU-intensive benchmark suite, stressing a system's processor, memory subsystem and compiler. SPEC designed CPU2006 to provide a comparative measure of compute-intensive performance across the widest practical range of hardware using workloads developed from real user applications.
CPU2006 tests a mix of application both for the efficiency of integer math test and for floating-point computation. The list of application in the float-point test (CFP2006) are listed here: .
