Sisoft Sandra puts the boot on the other foot however and claims that AMD's K10 architecture has phenomenal raw bandwidth compared to the older K8 CPUs and both are still light years ahead of what the Intel CPU has access to.

Whereas Everest is entirely single-threaded still, Sisoft Sandra tests multi-threaded memory access performance - this is why the triple core Phenom at just 2.1GHz has more bandwidth than everything else. The latency is more GHz driven though, with the Phenom dropping down the table compared to the faster clocked Athlon K10s and K8s.
