3. Processor (CPU)

Intel Processor Categories:

• U series (Ultra-low power): Battery saver, lightweight laptops, less powerful. (e.g., i5-1235U)
• P series (Performance balance): Better than U, good for normal users.
• H series (High performance): Best for gaming, editing, heavy work. (e.g., i7-12700H)

👉 If you want performance → choose H series
👉 If you want portability & battery → U or P series

AMD Processors:

• Ryzen 3: Entry level, basic work.
• Ryzen 5: Mid-range, best balance (like Intel i5).
• Ryzen 7: High performance (like Intel i7).
• Ryzen 9: Extreme performance (like Intel i9).

👉 AMD Ryzen 5 & Ryzen 7 are best value for money (better multi-core performance, cheaper than Intel).

4. Graphics (GPU)

• Integrated (Intel Iris, AMD Radeon): Good for normal use, movies, study.
• Dedicated (NVIDIA, AMD Radeon RX): Needed for gaming, editing, 3D work.
  👉 For gaming/3D editing → NVIDIA RTX 3050 / 3060 or higher.
