What reviewers say

Reviews find it well suited to mixed content creation and audio processing. Puget favours it in Premiere Pro and Resolve, while Scan reports high DAW processing capacity once buffer settings are relaxed. Sample-heavy work at very small buffers still exposes latency limits; higher-core models provide greater rendering and compilation throughput.
