Now that you've had some time to digest Ken's look at the 2920X and 2970WX, take a look at how AMD's new silicon performed on other test beds.  Over at The Tech Report they ran the 2920X paired with DDR4-3200 and spent a fair amount of time testing workstation tasks including DAWBench VI tests.  There are also a number of games they tested which are not included in our suite so start your reading over there.

"While those figures may seem little changed from those of the Ryzen Threadripper 1920X, AMD's Precision Boost 2 technology promises a more graceful descent to that base clock as cores and threads become loaded down.""

Precisely what are AMD's XFR 2 and Overdrive?

Whether you have had a chance to play around with a new Ryzen processor or not, you might benefit from more information on what XFR2 and Precision Boost 2 are and what they are not.  [H]ard|OCP spent some time to write an article that dispels the rumours which have been spread, especially the fact that these are both unreleased at the moment.  Together they will provide support for Precision Boost Overdrive, which could be supported by Ryzen Zen+ CPUs on an X470 motherboard, at least in theory.  When enabled it will utilize the ability of the new Ryzen Master software to monitor your motherboards VRM usage and if it sees it is below it capacity it will relax the vCore limiter on your CPU allowing more juice to flow in which can be used to increase the frequency of your Zen + chip.  It will be interesting to see how effective this is, but for now all we can do is read about it.

"We wanted to put together a quick overview about what Precision Boost 2 and XFR2 are NOT about. It seems that slides leaked, and faked, earlier in the 2nd generation Ryzen's development have clouded some people's understanding on what features are included, but more important which features are not."
