What reviewers say

Reviewers find strong rendering and content-creation performance, often close to the older 32-core 3975WX while improving responsiveness. Puget Systems considers it a sensible alternative to the larger 5000 PRO chips for many editing applications. The costly motherboard and memory platform, and workloads that cannot use its resources, limit its appeal outside professional work.
