📊 Real-Time VRAM Mathematical Formulation & Derivation

How did we arrive at 82 GB? Below is the verified industrial infrastructure forecasting model.

The VRAM Forecasting Equation
Total VRAM = (Model Weights + KV Cache) × System Overhead
VRAM = ((Params × Bits / 8) + (Context / 1024 × 0.5)) × 1.25

1. Input Parameters & Constants Mapping

Model Variables
  • • Params (Model Size): 123 Billion
  • • Bits (Precision): 4-bit (Selected via slider)
Runtime Constants
  • • Context Window: 8,192 Tokens (Selected via slider)
  • • KV Cache Factor: 0.5 GB / 1K Tokens (Empirical baseline)
  • • System Overhead: 1.25 (25%) (CUDA Context & Activation buffer)

2. Step-by-Step Calculation Engine

[Step 1] Compute Model Weights Allocation:

Formula: (Parameters × Bits) / 8 Bytes per GB

➔ (123B × 4) / 8 = 61.50 GB

[Step 2] Compute Key-Value (KV) Cache Matrix Size:

Formula: (Tokens / 1024) × 0.5 GB Baseline

➔ (8192 / 1024) × 0.5 = 4.00 GB

[Step 3] Apply System Overhead Risk Buffer:

Formula: (Weights + KV Cache) × 1.25 CUDA Runtime Multiplier

➔ (61.50GB + 4.00GB) × 1.25 = 81.88 GB

[Final Step] Rounding Ceiling (Ceil):⌈ 81.88 ⌉ = 82 GB
