32 Zen 4 cores for a carefully planned professional workstation
32 cores / 64 threadsUp to 5.3 GHz boostSocket sTR5Tray CPU, 350 W TDP
The Ryzen Threadripper PRO 7975WX is a 32-core workstation processor for substantial rendering, simulation and software-build workloads. Its Zen 4 architecture combines a 4.0 GHz base clock with up to 5.3 GHz boost, alongside 32 MB L2 and 128 MB L3 cache. This exact 100-000000453 ordering code is the tray version.
Best For: Professional workstation builds that can use 64 CPU threads, registered DDR5 memory and substantial PCIe expansion.
Before you order: Requires an explicitly compatible sTR5 motherboard and BIOS, DDR5 RDIMM memory, a separate discrete graphics card and suitable cooling for a 350 W processor. It is not an SP6 or AM5 CPU. WRX90 unlocks the eight-channel platform; a supported TRX50 board has fewer channels and PCIe resources.
What's in the Box
- One AMD Ryzen Threadripper PRO 7975WX tray processor, order code 100-000000453.
- Thermal solution is not included. Motherboard, RAM, discrete GPU and other system parts are separate.
- Do not assume retail-box accessories or installation tools; confirm exact tray handling accessories with the supplier. The retailer reference photo is not a photograph of the specific supplied serial number.
What It Means in Practice
- Build a workstation for parallel CPU rendering, simulation or compilation where the application scales to many threads.
- Populate supported ECC DDR5 RDIMM modules according to the motherboard memory guide.
- Plan graphics, storage and expansion cards around the chosen motherboard lane routing.
- Select the cooler, chassis airflow and power supply for the complete workstation load.
What Will Not Work
- Maximum boost is workload and operating-condition dependent; 5.3 GHz is not a guaranteed all-core clock.
- Eight memory channels and full PCIe expansion require the appropriate platform, not just a matching socket.
- No integrated graphics output: a discrete graphics card is required.
- This tray SKU does not establish retail boxed accessories or the warranty terms of another seller.

Frequently Asked Questions
Is this the SP6 version?
No. AMD identifies this exact tray part as socket sTR5. Check the motherboard CPU support list and BIOS.
Is the cache 160 MB L3?
No. It has 32 MB L2 plus 128 MB L3, giving 160 MB combined.
Does it include cooling or graphics?
No cooler is included and a discrete graphics card is required.
Will any sTR5 board give eight memory channels?
No. WRX90 provides the eight-channel platform; TRX50 uses four channels and fewer PCIe resources.
Singular Expert Insight
Select the platform before the CPU cooler and RAM. WRX90 and TRX50 can support this processor but expose different memory and expansion resources. A confirmed BIOS, suitable RDIMM population and adequate cooling matter more than treating the peak boost clock as a sustained all-core target.
Buyer’s Guide
✓ Buy it if Your professional software benefits from 32 cores and you have a verified sTR5 workstation platform.
✕ Skip it if You need an AM5 upgrade, integrated graphics or a CPU supplied with a stock cooler.
→ Also consider Motherboard support, BIOS, RDIMM compatibility, lane routing, cooler coverage and complete-system power.
