Crack a PB 2 with AMD

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.""

A quick refresher and Dynamic Local Mode

In general, the rollout of AMD's second-generation Ryzen Threadripper processors has been a bit unconventional. While the full lineup was announced back in August, there has been a staggered release period.

Later in August, we first got our hands on the Threadripper 2950X and 2990WX, the 16 and 32-core variants. Even though both of these parts were reviewed at the same time, the 2990WX was available first, with the 2950X coming a few weeks later.

Now more than two months later, we are taking a look at the 12-core Threadripper 2920X and the 24-core Threadripper 2970WX which were announced alongside the Threadipper parts that have already been shipping for quite a while now.

Will these new Threadripper processors be worth the wait?

AMD Announces Threadripper 2970WX, 2920X Availability, New Dynamic Local Mode Feature

AMD has provided an update to their continued rollout of 2nd generation Threadripper CPUs, including the 12 and 24-core variants.

Both of these new Threadripper SKUs will be available starting on October 29th, for a price of $649 for the 12-core 2920X and $1299 for the 24-core 2970WX.

The more surprising announcement comes in the form of a new software feature for the Threadripper WX-series processors called "Dynamic Local Mode" which aims to address some of the performance issues caused by the non-traditional memory structure of these processors, where not all CPU cores have direct access to a memory controller.

According to the blog post on AMD's website, Dynamic Local Mode will run as a Windows 10 service and measure how much CPU time each thread is utilizing.

This service will then begin to reallocate these demanding threads to the CPU cores which have direct memory access until it runs out of available cores. In that case, the service will start to assign threads to the remaining cores.

This dynamic operation ensures for applications that aren't consuming all 48/64 threads on the WX-series processors, that direct memory access will be available when needed. In particular, this should provide an advantage to gaming, which typically takes up less than eight cores, but is dependant on fast memory access.

Users will be able to enable and disable this feature on the fly through the Ryzen Master, and it will not require a reboot unlike the existing Dynamic/Local mode toggle for the Threadripper X-seres processors.

AMD is claiming that they've measured up to a 47% increase in performance with Dynamic Local Mode enabled while gaming in certain titles.

Dynamic Local Mode is set to be enabled with a new version of AMD's Ryzen Master software, available alongside these new Threadripper SKUs on October 29th. We hope to have hands-on this software beforehand to test how this fixes some of the issues we saw in our initial review of the Threadripper 2990WX. Stay tuned for more info!
