AMD Ryzen 3 3300X CPU Review

Clock Speed Power and Temp

Before we dive into performance, let’s start by looking at the clock frequencies we experienced with the CPU, its full-load total system Wattage, and Package Temperature in Celsius.  Note that the ambient temperature of the room while testing was 71F.  The test bench is an open-air test system.  The cooling device used was a Corsair Hydro H115i closed-loop liquid cooler on the highest performance profile in Corsair Link.  The power supply in the system is a Seasonic 1000W Titanium.  Total system Wattage is taken at the wall.  Cinebench R20 is used for clock speed, temperature, and Wattage testing.

Clock Speed

The boost frequency on the Ryzen 3 3300X is 4.3GHz and the base is 3.8GHz.  Below you will see what we experienced while running Cinebench R20 on all threads.

Note that Precision Overdrive was disabled.  Our CPU reached a maximum of 4.342MHz.  In fact, HWiNFO says the CPU Boost Max is 4350MHz.  But this was only in a short burst, it was not sustained.  The actual sustained clock speed for each thread as you can see was 4.291GHz, which is right in-line with the 4.3GHz it should be boosting at.  We were actually reaching that frequency.

In this second clock speed picture above you can see it running full-throttle at 4.292GHz on all four physical cores in Cinebench R20, not over.


Ryzen 3 3300X Power Testing

In terms of total system Wattage at the wall, the AMD Ryzen 3 3300X consumed the most Wattage running Cinebench R20 at 124W.  This is 16% more power than the AMD Ryzen 3 3100.  We also see that the two Intel CPUs actually pull the least amount of power in our testing.  Keep in mind the Ryzen 3 3300X has the most threads supported and runs at the highest clock speed.


Ryzen 3 3300X Temperature Testing

For temperature, we are taking the package temp reading in HWiNFO.  Our Ryzen 3 3300X hit the highest temperature at 67c in Cinebench R20.  This was 5% higher than the AMD Ryzen 3 3100.  The two Intel CPUs were actually quite a bit cooler.  These temperatures are not bad or high though, these are respectable temperatures considering the thread count and clock speeds.
