Electrical Specifications
NOTES:
1. These are pre-silicon estimates and are subject to change.
2. Minimum values assume Graphics Render C-state (RC6) is enabled.
3. V
AXG
is a VID-Based rail driven by an Intel MVP6.5 compliant voltage regulator.
4. This specification assumes Intel Turbo Boost Technology with Intelligent Power Sharing is enabled.
