Wow that's high power consumption! Good thing you are running liquid cooling! Compare that to the AMD 3700X at half the power! Still, basic power consumption measurements never tell the full story – the Ryzen processors also dominate the renders-per-day efficiency metrics. That advantage really shines through when we take a look at power consumption during our HandBrake x264 and x265 workloads. As always, take power readings during overclocking with a grain of salt, as fine-tuning and motherboard firmwares have a huge impact here.Īs expected, the Core i7-10700K consumes much more power than the Ryzen 3000 chips, but that isn't surprising given their denser and more power-efficient 7nm node. We logged similar power consumption during our overclocking efforts, with the 10700K's fixed 5.1 GHz clock rate yielding a maximum of 211W under load, compared to the 9900K's 5.0 GHz overclock that pulled down 206W. The Core i7-10700K also draws less power than the 9700K, which has the same core count but doesn't come with Hyper-Threading. As you'll see in the application testing later, the 10700K delivers faster performance, meaning that, compared to its spiritual predecessor, it yields a comparatively solid increase in power efficiency in SIMD workloads. That's impressive given that both chips run at 4.7 GHz on all cores during the test. At stock settings, we logged an average of 147W of power consumption for the Core i7-10700K during the AVX-intensive multi-threaded y-cruncher workload, which is 9% less power than the similarly-equipped Core i9-9900K.
