Three leading makers of motherboards on Friday disclosed specifications of yet-unannounced AMD Ryzen Threadripper 1920 processor. The chip has 12 cores, works at slightly lower frequencies than the model 1920X, but also comes with a lower TDP. Unfortunately, it is unknown when the product is set to become available.

So far AMD has publicly introduced three microprocessors in its family of CPUs for super high-end desktops/workstations: the Ryzen Threadripper 1950X (16 cores, 3.4 GHz), the Ryzen Threadripper 1920X (12 cores, 3.5 GHz), and the Ryzen Threadripper 1900X (8 cores, 3.8 GHz base). AMD has never made any announcements regarding any other members in the Ryzen Threadripper family, or if three would be the limit - and it appears there is at least one more incoming. According to CPU support lists of the ASUS ROG Zenith Extreme, ASRock X399 Professional Gaming/X399 Taichi as well as GIGABYTE X399-Gaming 7, which were published this week, the 1920 (without an X) will also make a showing.


From the GIGABYTE X399 Gaming 7 Support Page

The Ryzen Threadripper 1920 will have 12 cores with simultaneous multithreading, a 3.2 GHz base frequency, a 3.8 GHz turbo frequency, and the full 32 MB of L3 cache. The differences between the 1920 and the 1920X are lower clock rates and AMD’s XFR speed boost on the 1920: typically Ryzen CPUs without the X have half the XFR.

Another difference is that the AMD Ryzen Threadripper 1920 will have a 140 W TDP, down from 180 W of the higher-end models, due to the lower frequency settings. This is for similar reasons as the 95W/65W TDP differences between the 1700X and 1700. The lower clock speed of the 1920 should be indicative of a slightly lower level of performance than the 1920X, and should mean that it will be cheaper than the 1920X ($799), but somewhat more expensive than the Threadripper 1900X ($549).

The fact that the Ryzen Threadripper 1920 is already supported by motherboards probably means that one can expect its launch in the coming weeks or months, but perhaps not right after the Ryzen Threadripper 1920X and the 1950X that land on August 10. Meanwhile, an interesting point to add here is that the CPU support lists from ASUS, ASRock and GIGABYTE do not indicate they support the 1900X with eight cores, which is announced to be on shelves on August 31st.

    Fills in a big gap in the price range. I'm guessing $649 to $699 pricing for this, probably the latter. Reply

    Depending on how the specs fill out on the 1900x I wonder if the 1800x will get pushed down in price.Or how much this will eat into sales of the 1800x. $50 diff for 200mhz base clock bump, 44 extra PCI lanes, and quad channel! Still the L3 to consider as well. That's a heck of an upgrade. Plus if you're already in that territory $100 premium for TR board, yer talking 150$ total. That's not a lot of money for what you get in return. That's quite a deal Reply

    There will be a TR 1900 between the Ryzen 1800X and 1900X as well. Reply

    At $50, why even have something to slot in there? I'm not complaining. just curious. AMD is competitive again and that's great for my wallet :D Reply

    Perhaps the intent was to wait until it made sense to drop the price of the 1800X anyways and, rather than dropping the whole stack, use the 1900 to fill in the gap. The introduction of the 1900 may be good news for buyers of the mainstream platform. Reply

    If that's the case, then awesome. pushing down the price makes it even more competitive. Will force Intels hand. Win Win! Getting ready to build a couple of desktops, so starting to shop around and price stuff out. Reply

    & going upwards, its only about $70usd more than the top TR to a 24 core 1P epyc. Reply

    So far, TR looks like a good product release aside from the insane TDP. I can say the same of Vega so I guess AMD across their primary products just can't manage any sort of power efficiency on the high end. If you can stomach the TDP, you're getting a good processor. I think I'll wait until mobile APUs hit the market to get too judgemental about Zen. Their mobile processors are going to be a lot more important than desktop components since laptops represent a large majority of computer purchases. If AMD can get into laptop hardware with a competitive product stack, they the company will do fine. If not, the niche of desktop and HEDT won't matter. A CPU-centric company can't survive on selling processors that are chained to power outlets in 2017. Reply

    I wonder if it will be worth it to wait for 10nm Threadrippers. I don't particularly like water cooling or loud air coolers. Reply
