Power and Temp
We are testing power at the wall and the package temp with HWiNFO. The temperature in our testing area was around 72c at the time of testing, we have an open-air bench system. Cooling was with a Corsair H115i. Our Power Supply is a 1000W Seasonic Titanium power supply.
In terms of power, the Intel Core i5-10600K did consume the highest amount. It pulled 163W at the wall and 103W package power. Next to it was the AMD Ryzen 5 3600X at 143W at the wall and almost 90W package power. The Core i5-9600K was the lowest power draw at 109W at the wall and almost 70W package power.
This can be looked at in two ways. There were some tests that showed the Intel Core i5-10600K on top of performance. It certainly was while gaming. Therefore the extra power is warranted since it was faster in those places. However, the reverse is also true because there were other tests, more multi-threaded tests that put the Ryzen 5 3600X on top in performance. In that case, since the Ryzen 5 3600X uses less power than it would be the more efficient CPU in those workloads.
Ultimately though, the extra power demand of the Intel Core i5-10600K over its predecessor, the Intel Core i5-9600K cannot be ignored. Power increases on the package by almost 50%. Power at the wall increases by also 50%. That’s a big power increase from generation to generation. The Ryzen 5 3600X seems to be sitting in a good position of balance between power consumption and performance.
Even though the power is way up on the Intel Core i5-10600K the temperature is still lower than the AMD Ryzen 5 3600X. In fact, it is the Ryzen 5 3600X that hits the warmest temps at 67c in our testing. Yet the more power-hungry Core i5-10600K actually runs cooler at 59c. This is with the exact same AIO cooler. Intel’s marketing about improving thermals is not hogwash with the 10th Gen series it seems. AMD needs to look into ways of improving thermals such as Intel has done at every layer, substrate to IHS.
