Preliminary Tests Of Intel Sandy Bridge & Ivy Bridge vs. Broadwell

Next up is the x264 video encoding test to just keep the CPU busy while giving the HD Graphics a rest.

The Core i7 X1 Carbon's power draw was 38% of the HP EliteBook with Core i5 Sandy Bridge CPU.

Even if factoring out the other component differences in a worst-case scenario, Broadwell is still a very healthy improvement over Intel's Sandy Bridge microarchitecture.

The efficiency of Broadwell is looking good compared to Sandy Bridge and Ivy Bridge, but again more laptops will be part of a comparison on Phoronix in the days ahead. On the following pages are a number of Linux benchmarks when running on AC power between these three laptops with the Core i7 5600U Broadwell, Core i7 3517U Ivy Bridge, and Core i5 2520M Sandy Bridge hardware.
