Power efficiency analysis
TFLOPS/watt and GB/s/watt — critical for data center TCO
NVIDIA RTX 5070 12GB
NVIDIA T4
TFLOPS/watt measures compute efficiency — how much AI throughput you get per watt of power consumed. For data centers with PUE of 1.2–1.5, a 10% improvement in TFLOPS/watt translates directly to lower electricity costs and cooling requirements. GB/s/watt measures memory bandwidth efficiency, which is the binding constraint for memory-bound LLM inference workloads.
When to choose each GPU
Choose NVIDIA RTX 5070 12GB for:
- Budget inference
- Small model serving
- Entry Blackwell compute
Weaknesses / Limitations
- 12 GB VRAM — only fits quantized models up to ~13B parameters
- No NVLink — cannot pool VRAM
- Consumer GPU — no ECC memory or enterprise support
Choose NVIDIA T4 for:
- Low-cost inference
- Edge AI
- Multi-tenant serving
Weaknesses / Limitations
- 16 GB VRAM limits model size to ~13B at INT4
- Low FP16 TFLOPS (65) — not suitable for throughput-sensitive serving
- Older Turing architecture — no Ada or Hopper efficiency improvements
