What you need to know

  • The AMD Threadripper 3990x is now available.
  • The CPU has 64 cores and 128 threads to deliver high performance.
  • The Threadripper 3990x is avaialble now from NewEgg for $3990 (opens in new tab)

The AMD Threadripper 3990x is now available through NewEgg (opens in new tab). AMD's latest Threadripper CPU brings 64 cores and 128 threads to help you render the most demanding workloads and games. AMD announced the CPU at CES 2020, including its impressive spec sheet. The Threadripper 3990x costs $3,990.

The Threadripper 3990x has 64 cores, 128 threads, and a combined cache of 288MB. It has 88 total PCIe 4.0 lanes to accommodate large GPU and NVMe requirements. It also has quad-channel DDR4 with ECC support.

It has NVMe RAID support, meaning you can combine up to six NVMe disks with Threadripper processors. You can double that bandwidth with PCIe 4.0 on AMD's TRX40 motherboards.

AMD positioned the Threadripper 3990x as a value proposition when compared to more expensive Intel hardware. AMD stated at CES that the Threadripper 3990x is around 30 percent faster than a dual Intel Xeon 8280 configuration, which costs around $20,000. The Threadripper 3990x is geared towards high-end professionals, so a price tag measured in thousands is normal.

  • For nearly $4000 it damn well BETTER be a MONSTER.
    If you are building a custom video-editing workstation, or engineering/CAD/Solid-Modeling/FEA workstation, then, yeah. It would make sense.
    Or if you are building a custom server for AI/Simulation/etc. (get TWO for that!)
    But, for a home user, or gamer. Pfffft.
    The motherboards alone that could properly support it will all be over $400, then add in the high-speed memory (512 GB or more to take advantage of all those threads), power supplies (yes, plural), and the truck-load of storage and rack-space to support it all........
    I'm sure my engineers at work will be ******* after this already (but it's cheaper to rent Cloud space to run their stuff.)
    Well. Yeah. It's cool and all, but it's the Cloud Providers who will be purchasing these in bulk (and the Universities building custom SuperComputers.)
  • It's not designed for home users so why would they buy it, or even bring them up?
  • Just curious, how many months work will recover the investment in the new monster compute server
  • This is not meant for cloud providers or university supercomputers, AMD produces the Epyc line for that. This is for workstation users and enthusiasts with money to burn. It's a halo product: low volume, high cost, high performance. And it's best in class for that space by a mile.
  • OK, well, then were are the "marketing blurbs" about the top-end Intel Xeon processors? Fair is Fair. OR, you can just go read the detailed info on them at AnandTech.
  • Air cooling is out of the question I guess? The heatsink needed to cool a 280W monster like this would be HUUUUGE
  • You mean Yuuuuge
  • It's actually almost as easy to cool it as the other 3rd gen threadrippers, therefore if you don't want to overclock it, air cooling will be enough
