Product Overview
AMD Ryzen Threadripper 3990X is the flagship 64-core, 128-thread desktop microprocessor based on AMD's Zen 2 architecture. The 3990X combines the I/O die with 16 Core Complex Dies (CCDs, each with 4 cores) while retaining comparable clocks with Ryzen 9 processors.
Like normal Ryzen processors based on the Zen 2 architecture, the 3990X comes with 64KB per core of L1 cache, 512KB per core of L2 cache, and 16MB per CCD of L3 cache. This sums up to 4MB of L1, 32MB of L2, and 256MB of L3 cache.
True to a Threadripper, the 3990X offers 64 lanes of PCI Express lanes, making multi-GPU, multi-NVMe setup (think RAID) uncompromised in performance. Unique to the Threadripper family amongst consumer desktop processors, the 3990X supports quad channel DDR4 up to 3200MHz.
The Threadripper 3990X is manufactured on TSMC's 7nm process and is designed for a TDP of 280W.
The two other Ryzen Threadripper processors in this series are the 24-core 3960X and the 32-core 3970X.

Reviewer score 63% (normalized by Neofiliac) AMD’s 64-core 3990X is limited. Aside from a few select instances (as mentioned, Corona, Blender, NAMD) the 32-core Threadripper for half the price performed on par or with margin. Unless you run those specific tests (or ones like it), then go for the 32 core and spend the money elsewhere. In the end, if you need more IO or more memory, get the EPYC, otherwise Threadrippers merits consideration.
Pros
- High core count
- Low power consumption
- Good performance
Cons
- Windows 10 Pro has issues
- Only 64 threads per core

Reviewer score 77% (normalized by Neofiliac)The 3990X is best suited for intense long-duration workloads, like VFX workloads that require 24-36 hours just to render one second of footage. If your render jobs typically finish in a few hours and you aren't running them 24/7, AMD recommends going with the Threadripper 3970X or 3960X. AMD's Zen 2 microarchitecture spreads the design across 8 eight-core 'core chiplet die' (CCD)
Pros
- Compact, high-contrast design
- Supports up to 256GB of DDR4-3200 memory
- Dual-channel PCIe 4.0
Cons
- No 48-core model
