[Beowulf] Benchmark/apps showing benefit from instruction set advances

I am searching an application or benchmark 
written in C, C++, or some ftn dialect. The 
benchmark must show that the more advanced 
instruction set enabled by the compiler, 
the  increased performance is achieved whilst running on a modern machine.

For example, using the Intel compiler and keeping 
the hardware constant, I would like to see a 
performance increase when compiling using -xK, 
-xW, -xP, -xT, and -xS. (SSE, SSE2, SSE3, SSSE3, SSE4).

The difference in performance must stem from the 
compiler's (or run-time's) ability to utilize the 
more advanced instruction set.

Any pointers appreciated.

Thanks, Håkon
