SiSoft Sandra tells much the same story - the 7850 offers little more than the 7750 at stock speeds, and overclocked breaks the 10,000MB/s barrier in raw numbers - almost twice as much as an Intel clocked to 4GHz. SiSoft indicates the unganged twin 64-bit K10 architecture affords far more multi-threaded bandwidth compared to the older K8 one though, although the latencies are again creeping upwards with clock speed.
