Temperature only lowers by 1 ☌ again during Handbrake. For another comparison, Core i7-2600K also draws around 150 Watts during video encoding when not overclocked but it takes close to twice longer than Ryto finish the task. Pretty much less efficient than Ryzen 7 1700. Overclock the Core i5-3570K to 4.5 GHz will make the CPU draws more than 150 Watts. While it sounds more efficient, it actually isn’t because Rycan finished the task twice faster than Core i5-3570K. My 5-year-old Core i5-3570K consumes about 120 Watts. However, 134 Watts during video workload is amazing for an 8-core processor. Undervolting only brings down the power consumption by merely 6 watts though. As you can see from the graph, power consumption during Handbrake video encoding is actually higher than during CPU-Z stress test.

Handbrake is a video encoding software and this software utilizes every threads and put a great balanced load across every thread. I choose Handbrake to represent real world power consumption. I can lower it a little bit more to 1.075 V but that’s unlikely to make drastic changes. So, I lowered to VCore on ASRock UEFI by 0.1 V which means the target VCore is 1.0875 V instead of the default 1.1875 V. Since Radeon R9 290 idle power consumption is rather inconsistent, I put out the card and switch it with Geforce GT 710 which turns out to much more consistent in power consumption. The specification of my system is as below : CPUĬooler Master CMStorm Sentinel Advance II I will measure the power consumption on 3 states : Idle, Load CPU-Z Stress Test, and Load Handbrake Test. I am not going to do any benchmark test here, I am just testing the processor power consumption and see how far low I can take it when undervolted. So, Rywill not likely become a bottleneck in gaming with this old Graphics Card. Mainly because I am still using a soon to be 4-year-old AMD Radeon R9 290. Gaming performance might seem disappointing for some people, but I am not going to talk about that. This processor isn’t going to beat Intel Core i7 6900K, but it is still a very fast processor. This is a nice and cheap Octa-Core Processor running at 3.2 GHz on all cores with precision boost enabled. I finally got my hands on AMD Ryzen 7 1700.

Update : I did a new test with lower voltage and AMD Wraith Spire Cooler
