• 3D Rendering: 50% higher efficiency in Blender for complex models, significantly reducing time in architectural design and animation production;
• Code Compilation: 73% faster multi-threaded compilation, greatly improving debugging efficiency for programmers;
• Multi-Instance Gaming: Supports simultaneous background processes (gaming + live streaming + screen recording) without frame drops, a limitation of the i9-11900H.

(3) iGPU Performance: Casual Gaming Without a Discrete GPU

• The i9-13900HK's 96EU iGPU delivers 80-90 fps in DOTA 2 and 120+ fps in League of Legends at 1080p medium settings, fully meeting casual gaming needs;
• The i9-11900H's 32 EU iGPU only achieves 45-55 fps (DOTA 2), requiring a discrete GPU for smooth 3A gaming.

III. Power Consumption & Battery Life: Balancing Performance Release and Mobility

1. Power Control Performance

• Full-Load Power Consumption: In FPU stress testing, the i9-13900HK stabilizes at ~54W (81℃) with a peak of 65W; the i9-11900H runs at ~45W (85℃) but with a lower performance ceiling.
• Intelligent Power Adjustment: The i9-13900HK supports Intel Dynamic Tuning, automatically adjusting power based on thermal conditions:
  • Gaming Laptops (Strong Cooling): Maintains 80-115W for maximum performance;
  • Thin-and-Light Laptops (Weak Cooling): Limits to 35-45W, ensuring basic experience via E-cores.
• Battery Life: On an 80Wh battery, the i9-13900HK delivers 6-8 hours of office use (web browsing + documents), 1-2 hours less than the i9-11900H; however, the gap narrows to 0.5 hours in heavy-load scenarios (video editing) due to higher efficiency.

2. Thermal Requirements Difference

The i9-13900HK's 115W peak power requires a high-end cooling system (dual fans + 4+ heat pipes, e.g., liquid metal cooling in gaming laptops); the i9-11900H's 45W power draw results in lower thermal pressure, supporting more thin-and-light models.
