Quite a lot if you play HD content, especially on slower CPU/APUs. The best thing the 'standard' version has is VAAPI in this regard. But that doesnt work well.
For example i have a bdrip 1080p mkv that uses ~60-80% CPU with software decoding (AMD A8-5500 APU with 12.12 release driver). VAAPI uses ~40-50, but i get artefacts, its unwatchable.
Xvba gives ~28% (give or take 1%, very small variations), works perfectly. For that matter, i get ~28% for any 1080p clip i play and ~20 for standard ones. Idle is at ~10%.
EDIT:
As of 12 RC3, idle usage is at 2-3% CPU, 1080p playback with Xvba ~19-20%. Nice.
