AMD has now disclosed the availability date for the two additional members of its 2nd Generation Ryzen Threadripper family. The AMD Threadripper 2970WX for extreme workstations as well as the AMD Threadripper 2920X for high-end desktops will be available for purchase globally on October 29.

The AMD Ryzen Threadripper 2970WX processor is similar to the 2990WX, which uses four eight-core Zeppelin dies on a single piece of substrate, but with one core disabled within each CCX (two per die). The CPU thus has 24 cores with SMT technology and running at 3.0-4.2 GHz, 64 MB of cache, a quad-channel DDR4-2933 memory subsystem, and 60+4 lanes of PCIe Gen 3. The chip has a 250 W TDP and therefore greatly benefits from the latest AMD X399-based motherboards with enhanced VRMs as well as high-performance coolers designed to dissipate such a vast amount of thermal energy.

Designed for high-end desktops for enthusiasts, the Ryzen Threadripper 2920X uses two Zen+ dies with two cores disabled within each of them. Running its 12 cores with SMT at 3.5-4.3 GHz, the chip offers 32 MB of cache, a quad-channel DDR4-2933 memory subsystem, and 60+4 lanes of PCIe Gen 3. With a TDP of 180 W, the “baby” Threadripper 2 is compatible with any AMD X399-powered platform with a proper BIOS. Meanwhile, since such chips are made to be overclocked, a motherboard with a reliable VRM and a robust cooler are highly recommended since power consumption and TDP tend to skyrocket on overclocked processors.

AMD is also noting today that these parts will feature a 'Dynamic Local Mode', designed to arrange the NUMA such that cores with direct access to memory have priority, although we will have to look deeper into this feature.

The AMD Ryzen Threadripper 2970WX processor will retail for $1,299, whereas the Ryzen Threadripper 2920X will cost $649. Both will be available on October 29 from leading retailers.

    You do not understand how mathematics work, and therefore you have no business making any attempt to correct someone.

    The sum of 24 and 12 is 36, any third grader can tell you that.

    24 / 32 = .75 or 75%. Better luck next time!

    Put simply, 32 is 33.3% more than 24, or 4/3. Conversely, 24 is 75% of 32, or 3/4. Just shift the numbers either side of the /. Reply

    woops. I was so annoyed by the dishonest TDPs that I didn't read the right numbers in the table in my rush to post!

    looks like the era of alternative facts has even infected basic arithmetic though! anandtech comments currently debating basic fractions!

    Dishonest? How so? I saw a graph somewhere that showed the new AMD CPUs boosting just enough to stay within a watt or so of the TDP when properly loaded, and not going over.

    If you increase the power limits, it's another thing entirely - namely overclocking, and then the CPU will consume more than 250 W.

    The TDP isn't set based on what a particular CPU model is capable of. Instead the manufacturer comes up with only a few convenient TDP points and assigns products to them. Then systems and cooling equipment can be designed based on few predetermined configurations, instead of each CPU needing specially designed hardware. Imagine if each of AMD's current CPUs had different power and cooling requirements!

    I wonder if there will be any improvements at all from the Windows scheduler, power management and certain applications for the particularities of 24 and 32 core Threadrippers.

    Comparisons of the same applications on Linux and Windows by two outlets (Phoronix and Techspot) show a gigantic difference.

    Users have also reported that some of the issues (but not all) involves bad power management on Balanced profile. The AMD profile released a year ago is equivalent to the current balanced and is still borked. Only High Performance Profile (or manual OC) resolves the issue of Windows taking too long to detect load to boost the CPU. So for bursty loads where a thread would consume cpu for a short period, then wait for i/o, and repeat, the cpu isn't turbo'ing and may not even reach max clock. Somehow this is more pronounced on Threadrippers than Ryzen.

    I guess you can add memory management into the mix as well, since where you allocate memory is tied to where you schedule your threads to run optimally Reply

    OS can now automatically migrate processes to the most appropriate cores. Reply

    two with direct access to local memory, and two with access to memory via the Infinity Fabric.

    sounds like a combination of trying to get as much raw speed out of the "active cores" as possible while the other ones are not dealing with as much load level so even if they run "at a slower clock" that is ok because they are not being tasked quite so hard so a bit more latency or lower speed will not "hurt" as much.

    AMD IMO is SERIOUSLY looking on how to make the experience better and better with worthwhile changes, whereas their 2 direct competition (Intel and Nv) are more focused on FUD to dismantle AMD stock price and/or putting stuff in there that is not ready for primetime, just so that they can jack the price as high as they possibly can (so early adopters being 100% legit guinea pigs)

    I do not "hate" Intel as much as I vastly despise Nv actions.

    12c/24t @ $649? Where do I sign for one of those... seems to be a pretty good sweet spot between price and performance. Reply
