AMD R5 1600X & 1500X Temp vs. Time

Thermal testing on the R5 1600X shows that, using our Kraken X62 cooler, we are not in danger of encountering a clock throttle at any point during the test; this wasn’t true for some previous CPUs, like the 1800X and 1700X units that had higher vCore out of the box. The 1700 and 1600X, however, are able to keep a flat clock when under the thermal torture test. The sporadic lines at the front-end illustrate XFR prior to test execution, if you’re curious.

We’re still working on running a separate thermal piece on Ryzen and are working on collecting info, as the tests are not necessarily as straight forward as normally. Stay tuned for that standalone content.


As for voltages and power, the 1600X draws about the same power from the wall as all the other Ryzen chips, expectedly, as does the 1500X. Under a Blender multithreaded workload, the 1600X stock CPU clocks at 3.7GHz across all cores, running a voltage of about 1.7 to 1.2vCore. Power draw is 145W constant with this workload, compared to 123W constant on the R5 1500X with its 3.6GHz speed and 1.2 to 1.24 vCore. Comparatively, the 1800X drew about 185W in the same test, with the 1700X drawing 168W and 1700 Stock CPU drawing 133W, pre-overclock.

Let’s move to competitive benchmarks, starting with Blender, Premiere, and then gaming.

Steve started GamersNexus back when it was just a cool name, and now it's grown into an expansive website with an overwhelming amount of features. He recalls his first difficult decision with GN's direction: "I didn't know whether or not I wanted 'Gamers' to have a possessive apostrophe -- I mean, grammatically it should, but I didn't like it in the name. It was ugly. I also had people who were typing apostrophes into the address bar - sigh. It made sense to just leave it as 'Gamers.'"

First world problems, Steve. First world problems.
