Intel Sandy Bridge (Core i5 2500K & i7 2600K) versus AMD Ryzen & Intel Coffee Lake: worth the upgrade?

Does your Sandy Bridge build need an upgrade? 86 tests provide the answer!

Power consumption

Last but not least - the power consumption. We measure the current flowing directly through the CPU power cables during various benchmark workloads. First of all, we measure the average consumption during the Cinebench 15 benchmark. We then measure the average consumption during the Adobe Premiere Pro benchmark. The last graph shows the idle power consumption.

Today's processors may be a lot faster, but the Sandy Bridge CPUs were a lot more economical. Under load, the i5 2500K and the i7 2600K consume 50 to 60 watts, while a modern Core i5 consumes 60 to 70 watts and an i7 870000K even more than 80 watts.

In idle, consumption has decreased considerably since the release of Sandy Bridge, when Intel CPUs are concerned.
