• Verdict: STRONGLY IN FAVOR OF LOCAL GPU

Cost Analysis:

• Local GPU: $0.002 (150W × 0.96h × $0.15/kWh)
• Cloud GPU (AWS g4dn.xlarge): $0.049 ($0.526/hr)
• Savings: 24x cheaper on local GPU

Performance Advantages:

• Zero network latency (instant iteration)
• Full debugging control (breakpoints, profiling)
• 100% availability (local machine)
