The Everest benchmark is single-threaded, so the extra cores of the Lynnfield CPU won't help it. Regardless though, it puts a massive gap between itself and the newer Clarkdale CPUs - whether reading, writing or copying.

Compared to the previous generation LGA775 system, there's a notable jump in read and copy performance when you compare the identical DDR3-1333 setups, but write performance remains the same. Clearly the limiting factor here again is not the memory infrastructure - since DDR2-800 also commands the same result - so there is space for more commands fired from the CPU.

In terms of memory latency, we have the same result as Sisoft Sandra: the Clarkdale CPU is the slowest one to access DDR3, with the AMD AM3 socket and older X48 generation of Intel hardware offering more efficient access.
