Power and Temperature and Frequency
On this page, we are going to investigate the Intel Core i5-14600K power draw, temperature, and frequency. This is a stress test, which means we are pushing each CPU to its maximum potential in all-core load in the Cinebench R23 multi-core test for 10 minutes.
Power
We use HWiNFO64 sensor data to record the results. We report on the sensor data for “Package Power” in Wattage.
This graph shows that the new Intel Core i5-14600K does eat more power than the Intel Core i5-13600K to achieve higher clock speeds and higher performance. At 170.9W it consumes 12% more power, or 18W more than the 13600K. That power increase doesn’t really scale linearly with the performance increase, therefore overall it is not very power efficient to gain the extra percentages of performance. Compared to the Ryzen 7 7700X it uses 23% more power and compared to the Ryzen 5 7600X it uses 48% more power. It’s friendlier than the Intel Core i9-14900K of course on power, but the AMD CPUs are still more power efficient, albeit slower on performance in multi-threaded/core workloads.
Temperature
We use HWiNFO64 sensor data to record the results. We report on the sensor data for “Tcidle” in Celsius.
Temperature is not a problem for the Intel Core i5-14600K, it hit only 78c at its peak on an all-core workload. This means it actually runs a lot cooler than the Ryzen 5 7600X and Ryzen 7 770X, by a wide margin. The Ryzen 7 7700X can get up to 96c, but the 14600K will barely even reach 80c. This makes it about 5 degrees hotter than the 13600K, but considering how low it already is, that isn’t much of a heat increase. Keep in mind that it is running at a much higher power demand than the 7700X and 7600X, but still remains cooler, that is pretty impressive for the 14600K.
Frequency
On the left screenshot, we are looking at the Intel Core i5-14600K maxed out on all-cores at a full-load. We can see that the P-cores hit a maximum sustained 5300MHz and the E-cores hit a maximum sustained 4.0GHz. These are exactly the specifications for the boost clocks that Intel specifies, so it is not throttling clock speed at all and can maintain this. In the right screenshot below we are running a single-core load. We can see that it again hits 5300MHz on the P-core and maintains this with no problem, hitting the Intel targeted speeds without throttling.
