For a more powerful system, an Intel Core i7 3770K "Ivy Bridge" setup was also benchmarked. The i7-3770K has a base frequency of 3.50GHz with four physical cores plus Hyper Threading. An SSD was in this system with its stock Ubuntu 12.04 x86_64 installation.
The system's AC power consumption, with the HD 4000 integrated graphics and SSD included, while idling on an Ubuntu 12.04 installation had a 41 Watt average power consumption.
The Core i7 3770K "Ivy Bridge" system produced 277 Mop/s for EP.C, which was more than five times faster than the 12-core ARM cluster.
The average power consumption for the Ivy Bridge system was 107 Watts under this load, which worked out to 2.58 Mop/s per Watt. The Ivy Bridge system for this workload was even more efficient than the PandaBoard ES at 1.78 Mop/s per Watt. The Ivy Bridge system was even with an SSD and other attached components requiring additional power than the ARM setup.
