System Builder Marathon, Q2 2013: $2500 Performance PC

Sandra's Arithmetic module demonstrate a Core i7 performance advantage in the new build that exceeds its clock difference. The costlier CPU also has more shared L3 cache, and Intel’s Hyper-Threading technology helps with utilization as well.

The new build slightly underperforms the old in one of Sandra’s Cryptography tests, but the difference is too small to cause concern.

The new build also has slightly less memory bandwidth, even at identical frequencies and primary timings. Eight-gigabyte modules are twice as dense as 4 GB modules, so the difference could be due to slower secondary timings.
