Performance comparisons

TPC-C performance

The Transaction Processing Performance Council benchmark TPC-C results for Woodcrest,

Clovertown, Tulsa, Nehalem, and Dunnington processors are compared in Figure 14. TPC-C is

measured in transactions per minute (tpmC).

SPEC performance

The Standard Performance Evaluation Corporation (SPEC) CPU2006 benchmark provides

performance measurements that can be used to compare compute-intensive workloads on different

computer systems. SPEC results for Woodcrest, Clovertown, Tulsa, Tigerton, and Nehalem processors

are compared in Figure 15. SPEC CPU2006 contains two benchmark suites: CINT2006 for

measuring and comparing compute-intensive integer performance; CFP2006 for measuring and

comparing compute-intensive floating point performance. The performance results show that the four-

core processors—Clovertown, Tigerton, and Nehalem—performed better in the SPEC tests.
