Sandra’s Arithmetic benchmark slaps my $2400 PC around with a dose of reality. Of course, I should have expected it. Because the top-end and mid-level systems use the same Core i7-4770K CPU, they fare comparably. As consolation for what appears to be a waste of cash, the expensive machine’s higher-end cooling subsystem facilitates a slightly higher overclock. I can also be glad that pure synthetics aren't included in our final value calculation.
The $750 PC only has two physical cores, and even then it fails to produce half the Dhrystone performance of its rivals. Its lack of overclocking capability is also significant, though Intel recently offered hope for future low-cost machines.
The bandwidth-sensitive Cryptography module punishes Don's $1600 PC, since he effectively ran the stock configuration with underclocked memory. In contrast, it rewards the $2400 PC’s memory overclock, even though both systems employ the exact same CPU.
That same difference in memory bandwidth is vividly exposed in the Memory Bandwidth module, where even the $750 machine outperforms Don's baseline configuration.
