2. Critical Hardware Components

GPU Acceleration

  • VRAM Requirements:
    • 7B: ≥12GB (RTX 3090/4090)
    • 32B: ≥24GB (A100 40GB)
    • 70B: ≥80GB per GPU (H100 cluster)
  • Quantization Optimization:
    • 4-bit: Reduces VRAM needs by 75% (e.g., 7B-4bit runs on RTX 3060 12GB)
    • 8-bit: Balances precision loss (~3%) and cost savings

CPU & Memory

  • Multi-Core Requirement:
    • 7B: 4-core CPU (AVX2 support)
    • 70B: 32-core CPU (AVX-512 for matrix acceleration)
  • Memory-to-Model Ratio:
    • FP16 models: RAM ≥ 1.5× model size (e.g., 32B model needs 48GB RAM)
    • 4-bit models: RAM ≥ model size (7B-4bit requires 7GB RAM)

Storage & Network

  • SSD Speed:
    • Model loading: ≥7GB/s (NVMe PCIe 4.0)
    • Checkpointing: ≥14GB/s (RDMA-enabled NVMe-oF)
  • Network Bandwidth:
    • Multi-GPU setups: ≥100Gbps InfiniBand/RoCE

3. Deployment Scenarios & Solutions

Personal/Developer Setup

  • Budget: 500−500-500−1,500
  • Components:
    • GPU: RTX 3060 Ti (8GB)
    • CPU: Ryzen 5 7600 (6-core)
    • RAM: 32GB DDR5
    • Storage: 1TB NVMe SSD
  • Capabilities: Runs 7B-4bit models at 5-10 tokens/sec

Enterprise Research

  • Budget: 50k−50k-50k−200k
  • Components:
    • GPU: 4x A100 80GB
    • CPU: AMD EPYC 9654 (96-core)
    • RAM: 512GB DDR5 ECC
    • Storage: 4TB NVMe RAID 0
  • Capabilities: Handles 70B models with 0.5s latency

Cloud Alternative

  • Cost: 2−2-2−5/hour (AWS p4d instance)
  • Benefits: On-demand scaling for 70B+ models without upfront hardware investment

4. Optimization Strategies

  1. Mixed Precision Training:
    • FP16 for training, INT8 for inference (20% speedup)
  2. Memory Management:
    • Use accelerate library for CPU-GPU memory offloading
  3. Distributed Inference:
    • Split model layers across GPUs (e.g., 4090+3090 for 32B model)
