What reviewers say

Reviews find strong CPU video, effects and audio processing performance. Puget finds it competitive in After Effects and CPU video codecs; Scan’s DAWBench testing shows substantial capacity but weaker sample-library and routing performance at the smallest ASIO buffers. Higher-core models finish heavily threaded rendering and compilation faster.
