Twenty-four Zen 5 cores for a dedicated workstation build
24 cores / 48 threadsUp to 5.4GHz128MB L3350W TDP
The AMD Ryzen Threadripper 9960X brings 24 cores and 48 threads to a high-end desktop workstation. Its Zen 5 architecture combines a 4.2GHz base clock with boost up to 5.4GHz, 24MB L2 and 128MB L3 cache. This is the tray part 100-000001595, designed for the sTR5/TRX50 platform with four-channel DDR5 registered memory.
Best For: Compatible rendering, video-production, compilation and engineering applications that can use many CPU threads and a workstation expansion platform.
Before you order: Confirm explicit Threadripper 9960X support and BIOS with the TRX50 motherboard vendor. Use supported DDR5 RDIMM memory, suitable sTR5 cooling for a 350W CPU and a discrete graphics card. Ordinary AM5 boards and DDR5 UDIMMs are not the specified platform. Tray supply does not include a retail cooling bundle.
What's in the Box
- AMD Ryzen Threadripper 9960X processor, tray/OEM part 100-000001595.
- Provide cooling separately. Hardware illustrations do not imply retail packaging, a motherboard or other accessories are included.
What It Means in Practice
- Match memory modules and population to the motherboard’s DDR5 RDIMM support list.
- Plan GPU and NVMe expansion against the actual board slot wiring and available lanes.
- Provide adequate case airflow, CPU cooling and power delivery for the whole workstation.
- Check application licensing and CPU-thread scaling before selecting a workstation configuration.
What Will Not Work
- CPU only; motherboard, memory, graphics card, storage and cooling are separate.
- This is the non-PRO 9960X; do not assume PRO-series features or eight-channel memory.
- Maximum boost is workload and system dependent, not a sustained all-core clock guarantee.
- 350W TDP is a processor design rating, not total system power consumption.
Key Features
24 cores, 48 threads
Parallel CPU resources for software designed to distribute work across threads.
Four memory channels
DDR5 RDIMM support up to 6400MT/s with ECC enabled by default; actual speed depends on the validated configuration.
Expansion platform
PCIe 5.0 support and 92 total / 88 usable native lanes; the motherboard determines available slots and routing.
Dedicated graphics required
Choose a separate GPU to suit the display, professional applications and their supported drivers.

Frequently Asked Questions
Is this the PRO 9965WX?
No. This listing is the non-PRO Ryzen Threadripper 9960X, tray SKU 100-000001595.
Can I use ordinary desktop DDR5?
AMD specifies registered DDR5 RDIMM memory. Follow the motherboard support list, capacity limits and population guidance.
Does it provide integrated graphics?
AMD specifies that a discrete graphics card is required.
Does it include a cooler?
No included cooler is claimed. Choose appropriate sTR5 cooling and verify the case and motherboard clearances.
Is 5.4GHz the base clock?
No. Base frequency is 4.2GHz. Up to 5.4GHz is the maximum boost specification.
Singular Expert Insight
Build around the complete platform rather than core count alone. The 9960X combines twenty-four cores with four registered-memory channels, but a compatible BIOS, adequate cooling and the motherboard’s PCIe layout determine how the finished workstation can be used.
Buyer’s Guide
✓ Buy it if Your software benefits from 24 cores and you are building a validated TRX50 workstation.
✕ Skip it if You need AM5 compatibility, ordinary desktop memory, integrated graphics or an included cooler.
→ Also consider Motherboard CPU list and BIOS, RDIMM compatibility, cooling capacity, GPU needs and software licensing.
