Power efficiency analysis
TFLOPS/watt and GB/s/watt — critical for data center TCO
NVIDIA RTX 4080
NVIDIA V100 32GB
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 4080 for:
- Budget fine-tuning
- Small model inference
- Consumer AI
Weaknesses / Limitations
- 16 GB VRAM limits model size — cannot run 34B+ models
- No NVLink — cannot pool VRAM
- Consumer GPU — no ECC memory
Choose NVIDIA V100 32GB for:
- Legacy ML training
- Budget HPC
- Mature framework support
Weaknesses / Limitations
- Volta architecture — significantly lower TFLOPS than A100 or H100
- 32 GB VRAM ceiling limits modern LLM workloads
- No BF16 support — less efficient for modern transformer training
