This test is just-for-fun test. It might not provide a real-world applications performance, anyone who read this shouldn’t take this into account for their sizing.

*Thread number is run according to CPU thread (16 – PS701, 8 – PS700, 128 – T3-1) except lusearch was done with 128T on every platform.

Results show that Power7 provides significantly much better performance in most of the tests. Sparc T3 shows better performance in Lusearch and Sunflow.
