Which is better for 3D rendering?

The 5995WX. Renderers like Blender and V-Ray scale with cores, and 64 cores and 128 threads will finish frames far faster than 16 cores. The 5955WX is the value pick only if renders are occasional.

Is the 5955WX faster for CAD?

Often yes. Its 4.0 GHz base clock beats the 5995WX's 2.7 GHz, and most CAD operations are lightly threaded. The 5995WX only pulls ahead when the model or simulation uses many threads.

Do they use the same motherboard?

Yes. Both are Socket sWRX8, 280 W, DDR4-3200 with 8 memory channels, so a WRX80 board works with either. You can move between them without changing the platform.

Is the 5995WX worth the extra money?

Only if your software uses the cores. At $1,839.99 versus $699.00 as of November 3, 2026, the 5995WX costs about $1,140 more. For rendering, simulation or large data jobs that bill by the hour, that pays back; for CAD and office work it does not.

Which one supports ECC memory?

The 5995WX lists ECC support and up to 2 TB of DDR4-3200. The 5955WX specs given say no ECC support. If you run long unattended jobs where a memory error is costly, pick the 5995WX.

Do either have integrated graphics?

No. Both need a discrete graphics card. The 5995WX also offers 128 PCIe 4.0 lanes, which helps if you run several GPUs.

AMD Ryzen Threadripper PRO 5955WX Processor vs AMD Ryzen Threadripper PRO 5995WX Processor

Buy the 5995WX if your work scales with cores: 3D rendering, simulation, video encoding, or large data jobs. Buy the 5955WX if you need high single-thread speed for CAD and lighter multitasking and want to spend far less. The gap is wide: $699 at eBay versus $1,839.99 at Newegg.com, both as of November 3, 2026. Both are sWRX8, 280 W, DDR4-3200, 8-channel parts, so the platform cost is the same.

Today the AMD Ryzen Threadripper PRO 5955WX Processor costs $1,077.99 less at its best price.
