Also called amd ryzen threadripper pro 9985wx, ryzen threadripper pro 9985wx, 9985wx, ryzen-threadripper-pro-9985wx
AMD Threadripper PRO desktop processor on Zen 5, with 64 cores and 128 threads and 65536 KB L2, 256 MB L3 at 350 W TDP on a 4 nm process and no integrated graphics.
What you need to know
Still a capable Threadripper PRO desktop chip.
AMD Ryzen Threadripper PRO 9985WX launched in 2025., It has 64 cores and 128 threads on Zen 5, dropping into the sTR5 socket. It is no longer the newest SKU in every store, but the chip is still useful when the rest of the PC keeps up.
- Still good?
- Yes, for most work this class is sold for
- Product age
- 1 year old
- Upgrade pressure
- Low
What this hardware means today
Age and usefulness are not the same number. This page keeps them separate.
- Performance today
- Excellent. Excellent for the class when RAM, storage, and the GPU keep up.
- Product age 1 year old
- Current generation. Launched 2025. Newer platforms exist. That does not make this chip unusable by itself.
- Support status
- Supported. Current Windows and current applications still run on this class of CPU. Platform BIOS support depends on the motherboard or laptop vendor.
- Upgrade pressure
- Low. Upgrade pressure is low unless you need a different platform feature.
Where does it sit?
Zen 5 sits on AMD's recent Zen desktop and laptop timeline. Later chips keep the brand and change the core.
Performance context
These are qualitative readings, not a fake 8.7 out of 10. Workload still wins.
Gaming: Very Good
Plenty for current games when the GPU is the limit, which it often is.
Productivity: Excellent
64 cores cover office, browser, and compile work in this class.
Multithreaded workloads: Very Good
128 threads. Heavy encodes still scale further on higher-core parts.
General use: Excellent
Everyday Windows use is not where most people notice this SKU first.
Efficiency: Average
Rated 350 W base power. That is a platform number, not a promise about your cooler.
Should you upgrade?
Probably not if this chip already matches your work.
Upgrade makes more sense if
- Your workload is strongly CPU limited
- You need a newer platform for memory, I/O, or chipset features
- You need substantially more multicore performance
- You need newer connectivity that your current board cannot offer
Upgrade makes less sense if
- The GPU is the real bottleneck
- Current applications are already responsive
- The CPU rarely limits your workload

Compatibility
| Socket | sTR5 |
|---|---|
| Board | A shared socket is not automatic compatibility. Check the motherboard CPU list and BIOS revision. |
| Memory | DDR5 |
| Graphics | Requires a discrete GPU. This SKU has no iGPU. |
A shared socket is not automatic compatibility. Boards often need a BIOS update before a newer chip in the same socket will post.
Cooler clearance, VRM quality, and power limits matter as much as the socket name.
Do not expect a display from the motherboard video ports. This SKU has no integrated graphics.
No display after install
This SKU has no integrated graphics. A machine with no discrete GPU will not show a picture. That is expected, not a dead CPU.
