Even though Don’s $1300 machine overclocked as well as my $1600 PC, Sandra's Arithmetic module reports that his overclock performance is less than my baseline. Since both Haswell-based processors have the same number of physical cores, I can only credit Intel's Hyper-Threading technology and a little extra last-level cache for allowing my CPU to outperform by such a wide margin.
Sandra's Cryptography routine shows closer performance scaling between the two quad-core PCs, while Paul’s little dual-core chip suffers from Intel’s disabling of various high-end features (including much of its cache and AES-NI).
Tired of my good-natured jabs over his previous memory benchmarks, Don Woligroski used DDR3-2400 to prove his machine’s metal in Sandra's Memory Bandwidth test, achieving 28 GB/s. Conversely, my lower-profile DDR3-1866 modules reach only 30 GB/s when manually configured to the same frequency and latency.
