Single- And Multi-Threaded Efficiency
The total run time for all single-threaded applications doesn’t differ by a lot. In the end, though, Sandy Bridge's higher clock rate secures the victory. The power draw tests, however, favor Ivy Bridge.
Thread-optimized applications show us a similar picture. However, the Core i7-3960X and its six-core architecture exhibits dominant performance. Factoring power into the equation, though, gives Ivy Bridge another clear win.
