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?

Noctua, for a cool quiet Threadripper

With the arrival of the second generation of Threadripper processors comes Precision Boost 2 and Precision Boost Overdrive which changes the testing process when it comes to heatsinks.  PB2 means that your processor will not let its self get above 68C and will reduce power and frequency to accomplish that.  This means that when testing, what [H]ard|OCP is looking for is clocks and power draw, not temperature.  Check out how they accomplished this, as well as the performance of these three Noctua coolers, as compared to themselves, the WraithRipper and the Silver Arrow.

"We take all three Noctua air coolers built for AMD Threadripper CPUs and put these to the test on both the 2950X and 2990WX. We run the NH-U14S, NH-U12S, and NH-U9 through the paces with both Precision Boost 2 and Precision Boost Overdrive using multiple fan configurations and compare these to the Silver Arrow and Wraith Ripper too."

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

Subject: Processors | October 5, 2018 - 04:42 PM |
Tagged: ryzen, Threadripper, 2990wx, 2970wx, 2950x, 2920x, dynamical local mode, NUMA, UMA

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!

AMD's Ryzen Threadripper 2950X now available for purchase for $899

Subject: Processors | August 31, 2018 - 10:36 AM |
Tagged: Threadripper, ryzen, 2nd generation threadripper, 2990wx, 2950x

Today, AMD's 2nd generation Ryzen Threadripper 2950X has finally reached retail availability. As you might remember from the launch a few weeks ago, the 32-core Threadripper 2990WX has already been on store shelves, but the 2950X was set to arrive on August 31st.

For those that need a bit of a refresher on 2nd generation Threadripper, you check out our full review of both the 2950X and 2990WX. Ultimately, we found the Threadripper 2950X is a great CPU for people looking to bridge the gap between content creation and gaming, with near top-level performance in both areas.

So far, we've spotted the 2950X on Newegg and at Microcenter, and Amazon.

ThreadRipper 2: Die Four Real

Tagged: Zen+, Threadripper, second generation threadripper, ryzen, Intel, Core i9, 7980xe, 7960x, 7900x, 2990wx, 2950x

The 2950X and 2990WX are both ThreadRipper 2 chips but are very different beasts under the hood.  The 2950X has two active die similar to the original chips while the 2990WX has four active die, two of which utilize an Infinity Fabric link to the other two to communicate to the memory subsystem.  The W in the naming convention indicates the 2990WX is designed for workstation tasks and benchmarks support that designation.  You will have seen our results here, but there are many other sources to read through.  [H]ard|OCP offers up a different set of benchmarks in their review, with a similar result; with ThreadRipper AMD has a winner.  The 2990WX is especially important as it opens up the lucrative lower cost workstations market for AMD.

"AMD teased us a bit last week by showing off its new 2nd Generation Threadripper 2990WX and 2950X packaging and specifications. This week AMD lets us share all our Threadripper data we have been collecting. The 2990WX is likely a lot different part than many people were expecting, and it turns out that it might usher AMD into a newly created market."

Widening the Offerings

Today, we are talking about something that would have seen impossible just a few shorts years ago— a 32-core processor for consumers. While I realize that talking about the history of computer hardware can be considered superfluous in a processor review, I think it's important to understand the context here of why this is just a momentous shift for the industry.

May 2016 marked the launch of what was then the highest core count consumer processor ever seen, the Intel Core i7-6950X. At 10 cores and 20 threads, the 6950X was easily the highest performing consumer CPU in multi-threaded tasks but came at a staggering $1700 price tag. In what we will likely be able to look back on as the peak of Intel's sole dominance of the x86 CPU space, it was an impossible product to recommend to almost any consumer.

Just over a year later saw the launch of Skylake-X with the Intel Core i9-7900X. Retaining the same core count as the 6950X, the 7900X would have been relatively unremarkable on its own. However, a $700 price drop and the future of upcoming 12, 14, 16, and 18-core processors on this new X299 platform showed an aggressive new course for Intel's high-end desktop (HEDT) platform.

This aggressiveness was brought on by the success of AMD's Ryzen platform, and the then upcoming Threadripper platform. Promising up to 16 cores/32 threads, and 64 lanes of PCI Express connectivity, it was clear that Intel would for the first time have a competitor on their hands in the HEDT space that they created back with the Core i7-920.

Fast forward another year, and we have the release of the 2nd Generation Threadripper. Promising to bring the same advancements we saw with the Ryzen 7 2700X, AMD is pushing Threadripper to even more competitive states with higher performance and lower cost.

Will Threadripper finally topple Intel from their high-end desktop throne?
