Our Ivy Bridge review shows that Intel's next-gen of Core processors offers more power and greater efficiency.
Intel Ivy Bridge: Video transcoding
We used CyberLink's MediaEspresso application to convert 16 short clips of 1080p Blu-ray video into a format designed for viewing on an iPad. MediaEspresso takes advantage of Intel's Quick Sync Video technology, leveraging the power of the built-in graphics processor.
Here, the Core i7-3770K outperformed its predecessor by 45 percent, completing the task in 1 min 37 secs compared to the 2 mins 21 secs of the Core i7-2700K. This is a clear indicator of the improved performance of the new graphics engine found in Ivy Bridge.
Intel Ivy Bridge: Gaming
Intel's integrated graphics aren't really powerful enough for the gaming enthusiast, but the new Intel HD 4000 graphics do deliver a significant improvement. It allows more challenging games to be played smoothly and with better graphics.
We ran our Crysis benchmark at 1280x720 resolution, and measured a 15.2 percent performance boost in low-quality mode. This increased to an impressive 36 percent when we stepped up to medium quality.
Intel Ivy Bridge: Power consumption
We also measured system power consumption with each of the chips installed, first with the system idle and then when running the aforementioned CyberLink MediaEspresso test.
There's not much to be gained when the PC is idle, but the average power consumption dropped from 58W for Sandy Bridge to 55W for Ivy Bridge.
Once the processors are put under load, the advantages of the 22nm process and Tri-Gate technology come to the fore. We measured an average power consumption of 142W for Sandy Bridge and 113W for Ivy Bridge. It's important to keep in mind that the Ivy Bridge processor achieves this lower power consumption while simultaneously performing the task 45 percent faster.
