## 2. Value Index & Algorithmic Scoring Methodology

SpecsBureau calculates a composite Value Score on a 0.0 to 10.0 scale using a weighted multi-category model:

\text{Overall Score} = \sum_{i=1}^{5} (w_i \times S_i)

Where:
1. **{\text{perf}}$ (Performance & SoC / CPU)** — Weight: .30$ (30%)
   - For Laptops: Processor tier (Ultra 9/7/5, Ryzen 9/7/5, M-series), Dedicated GPU (RTX 4090 to 4050), Total Graphics Power (TGP in Watts), RAM generation (DDR5/LPDDR5X).
   - For Smartphones: Flagship/midrange SoC (Snapdragon 8 Elite/Gen 3, Apple A18/A17 Pro, Dimensity 9400/9300), sustained thermal throttle resistance.
2. **{\text{display}}$ (Display & Ergonomics)** — Weight: .20$ (20%)
   - Panel technology (OLED, AMOLED, LTPO, Mini-LED, IPS), Resolution (4K, 2.8K, QHD+, FHD+), Refresh Rate (120Hz, 144Hz, 165Hz, 240Hz), Peak Brightness (nits), Color Gamut coverage (100% DCI-P3, sRGB).
3. **{\text{thermals\_optics}}$ (Thermals & Acoustics / Camera & Optics)** — Weight: .20$ (20%)
   - For Laptops: Cooling configuration (Dual-fan, vapor chamber, heat-pipes, acoustic dB under full load).
   - For Smartphones: Sensor size (1-inch, 1/1.3-inch), OIS, Optical zoom (3x, 5x periscope), ISP video bitrate and dynamic range.
4. **{\text{value}}$ (Price-to-Specs Value)** — Weight: .15$ (15%)
   - Hardware package relative to market segment MSRP ($ USD & ? INR).
5. **{\text{battery}}$ (Battery & Power / Portability)** — Weight: .15$ (15%)
   - Battery capacity (Wh for laptops, mAh for phones/tablets), Wired fast-charging wattage, Wireless charging standard (Qi2, MagSafe), Battery life runtime hours.

### Score Interpretation Table
