Power Consumption & Temperatures
For power consumption, it was no surprise that Haswell required a little more juice. With the higher TDP, under load, it used a little more power, but at idle, the power saving features did use less. For the CPU and GPU load, we used a GTX760 for graphics power load testing.
Looking at the results of the temperature test, we can see that Haswell was a warmer running processor. Even with a mild overclock, the 3770K topped at a 60.8c under load at 4.2GHz Even though Haswell was running 200MHz lower at 4.0GHz. Its temperatures were slightly higher than that. The highlight here is that at 4.4GHz, it topped out at 73.5c under load testing. Temperatures started to pick up quite a bit from its 1.30volts and up. As we mentioned in the overclocking section, the temperatures got quite up there with our higher overclocking attempts.
From the looks of this, for those who thought that the 3770K was a warm running chip, you will be in for a surprise with the 4770K, since it runs even warmer.
Now that we have covered all of our benchmarks with the Gigabyte Z87X-UD4H, let’s sum things up.
