Impossible to answer.  You need to benchmark the _specific_ program you are
interested on.  Each program can have a different "cache footprint".  The main
place this might help is in cases where the program's basic cache footprint is
>512kb, and < 1024kb.  Stretching the cache to 1024kb would allow the important
pieces of program to sit in cache where they could not on a 512K chip...
