Power Consumption, Overclocking

Moving on to ability consumption and hither in Handbrake the results might look a bit odd, given the 12-core and 24-core parts are seen pushing total system consumption to like levels, there are nonetheless a few reasons for this. Firstly Handbrake doesn't utilize the 24 and 32-cadre parts very well, so they aren't existence pushed every bit hard equally they could be. The other reasons include clock speed and voltage. The 2920X maintained an all-core clock speed of 3.95 GHz at 1.212v while the 2970WX ran at just three.55 GHz using one.075v. That's a x% decrease in frequency and an 11% subtract in voltage.

Blender is a better test to testify maximum system draw. Hither the 2990WX pushed total system consumption to 345 watts while the 2970WX arrangement consumed 10% less ability. This time the 12-core model is seen reducing system consumption by 15% which is reasonable given it runs at college clock speeds with more voltage.

In the end when fully utilized the 2970WX only pushed total system consumption 8% higher than that of the 7980XE and remember it was 30% faster in our Blender test. Meanwhile the 2920X pushed full consumption to 264 watts which is basically what nosotros saw from the 2950X and 7960X.

Operating Temperatures

When it came to temperatures both CPUs ran extremely cool, with the Enermax Liqtech 360 TR4 in identify we were looking at summit temperatures of xl-45 degrees after an hour long Blender stress test which is insane.

Therefore I removed the liquid cooler and tried out a big air-cooler, I went for the Wraith Ripper. The 2920X maxed out at just 61 degrees after an hour and over again this allowed it to run at the same three.95 GHz using 1.212v on the MSI X399 Creation.

Unbelievably the 2970WX ran just two degrees hotter hitting 63 degrees, again using the Wraith Ripper air-cooler on the MSI X399 Creation using default BIOS settings, just XMP was loaded. So when it comes to overclocking yous likely won't be limited by thermals.

Overclocking

Speaking of which, I could get both CPUs into Windows at 4.ii GHz simply but the 2970WX was able to pass our stress tests at that frequency. The 2920X would lock upwards later about x minutes of Blender and in the time we had available I couldn't stabilize the overclock. That said, with 1.3v at iv.1 GHz it was stone solid and spat out a score of 2653 pts, a six% boost over the stock out of the box performance.
