Sandra's Arithmetic module shows that the $2550 PC gets roughly three times the performance of the $650 build, though it costs roughly four times as much. The middle-budget machine also scales to approximately the middle of that chart.
The benchmark's Cryptography test demonstrates similar performance scaling with one exception: Paul’s overclocked machine appears to experience a hiccup in the combined Encoding/Decoding test, perhaps corresponding to less memory bandwidth.
Ah, the joys of quad-channel memory controllers. The $2550 PC has a little more than twice the bandwidth of the $650 machine. Since its memory wouldn’t overclock, the bump in performance must be credited to other parts of the system.
Don’s overclocked memory data rates were lower than Paul’s, and with worse latency settings. Yet, his Intel memory controller shines compared to Paul’s AMD-based build.
