Which is better for 3D rendering?

The 7985WX. Its 64 cores and 128 threads roughly double the 7975WX's 32 cores and 64 threads, and CPU renderers scale with core count.

Is the 7985WX worth the extra money?

Only if your software keeps most cores busy. At $7,404.00 vs $3,592.99 on November 6, 2026, you pay about double for roughly double the multi-threaded throughput.

Which is faster in single-threaded tasks?

The 7975WX. It boosts to 5.3 GHz and starts at 4.0 GHz, against 5.1 GHz and 3.2 GHz for the 7985WX.

Do they use the same motherboard and memory?

Yes. Both are sTR5 parts with 8-channel DDR5 up to 5200 MT/s, ECC support, 2 TB max memory and PCIe 5.0, so they fit the same WRX90 platform.

Do I need a new cooler?

Yes for both. Each is a 350 W part and neither ships with a cooler, so budget for a Threadripper-class cooler.

Which holds its value better?

Hard to say. The 7975WX has swung from $1,899.99 on November 3, 2026 to $3,592.99 on November 6, 2026, so check its price history before buying.
