AMD 3990X Threadripper

Announced at CES 2020, AMD’s 3990X Threadripper processor is a huge leap forward in processing power. The 3990X is designed for creators who need the best rendering performance to enhance productivity and work flow. With 64 cores and 128 threads, you’ll be able to run video encoding or rendering applications at blistering speeds and eliminate timeline lag.

Recommended CPU Cooling Solutions

While you can run an air cooler, such as the Noctua NH-D15S CPU Cooler, you may want to consider an All-In-One (AIO) water cooling solution with a 360mm radiator to maximize performance under heavy loads and minimize noise. We recommend the following for ease of maintenance and performance:

  • Corsair Hydro H150i Pro 360mm RGB Water Cooling Kit
  • EVGA CLC 360 360mm RGB Water Cooling Kit
  • NZXT Kraken X72 360mm RGB Water Cooling Kit
  • Corsair Hydro XC9 RGB CPU Water Block

Recommended RAM

For maximum performance, you need to feed all of those cores with a minimum of 64GB of fast RAM. Micro Center recommends the following kits:

  • Corsair Vengeance RGB Pro 128GB (4 x 32GB) DDR4-3200 Quad Channel Memory Kit
  • G.Skill Trident Z Neo Series RGB 128GB (4 x 32GB) DDR4-3200 Quad Channel Memory Kit
  • G.Skill Trident Z Neo Series RGB 64GB (2 x 32GB) DDR4-3200 Dual Channel Memory Kit
  • Other compatible options

Recommended Motherboards

  • ASUS TRX40 ROG Zenith II Extreme Alpha AMD sTRX4 EATX Motherboard
  • MSI TRX40 Creator AMD sTRX4 EATX Motherboard
  • Gigabyte TRX40 AORUS XTREME AMD sTRX4 ATX Motherboard
  • Other compatible options may require a BIOS update for optimal performance

1. Testing by AMD Performance Labs as of December 28, 2019 using the MAXON Cinema4D renderer via Cinebench R20.06 on the Core i9-9980XE, Core i9-10980XE, AMD Ryzen™ Threadripper™ 3970X and AMD Ryzen™ Threadripper™ 3990X processors. Results may vary. CPK-26

2. Based on AMD internal analysis, December 2019. CPK-24

3. Specifications of 3rd generation Ryzen Threadripper processors as of October 29th, 2019. The AMD 3rd Gen Ryzen Threadripper processors can deliver 133GB/s of concurrent device bandwidth. Intel’s competing high-end desktop processor, the Core i9-10980XE, can deliver up to 52GB/s of concurrent device bandwidth. CPK-14.

4. Max boost for AMD Ryzen processors is the maximum frequency achievable by a single core on the processor running a bursty single-threaded workload. Max boost will vary based on several factors, including, but not limited to: thermal paste; system cooling; motherboard design and BIOS; the latest AMD chipset driver; and the latest OS updates. GD-150.

5. AMD product warranty does not cover damages caused by overclocking, even when overclocking is enabled via AMD hardware. Visit www.amd.com/pb2 for more details. GD-26.
