Power efficiency on dedicated GPU hosting matters at two levels: the hosting provider’s operating cost (which feeds into your monthly price) and datacenter density. At 180 W TDP the RTX 5060 Ti 16GB is the most power-efficient AI card in our lineup.

TDP vs Real Draw
Specification TDP: 180 W. Typical draw under sustained load:
- Idle (persistence mode on): 15-25 W
- LLM decode (Llama 3 8B FP8 batch 8): ~150-165 W
- SDXL image generation sustained: ~170-175 W
- Peak burst: 180 W (rarely sustained)
Monthly power cost attributable to a single 5060 Ti at 50% utilisation: ~58 kWh. At UK industrial rates of ~18p/kWh: ~£10/month of power, before PUE overhead.
Tokens Per Watt
| Model | Draw | Aggregate t/s (batch 16) | t/s/W |
|---|---|---|---|
| Llama 3 8B FP8 | ~160 W | ~820 | ~5.1 |
| Mistral 7B FP8 | ~155 W | ~650 | ~4.2 |
| Qwen 2.5 14B AWQ | ~165 W | ~380 | ~2.3 |
| Phi-3-mini BF16 | ~145 W | ~1,100 | ~7.6 |
Images Per Watt
- SDXL Lightning 4-step 1024×1024: ~0.95 s at ~175 W = ~22 images per 1 W-hour
- FLUX Schnell 4-step: ~2.3 s at ~170 W = ~9 images per 1 W-hour
- SD 1.5 512×512: ~0.55 s at ~160 W = ~41 images per 1 W-hour
Density
At 180 W, four 5060 Ti cards fit a 1000 W PSU envelope with headroom for CPU, memory, fans, and PCIe risers. Compare to:
- Four 5060 Ti: ~720 W (typical) / 800 W peak
- Four 5090: ~2,300 W peak – needs enterprise PSU
- Four 5080: ~1,440 W peak – tight
For dense multi-GPU serving chassis, the 5060 Ti enables 4-8 cards per chassis. The 5090 tops out at 2-3 cards in the same envelope.
Lineup Comparison
| Card | TDP | t/s/W on Llama 3 8B INT8 |
|---|---|---|
| RTX 5060 Ti 16GB | 180 W | ~5.1 |
| RTX 4060 Ti 16GB | 165 W | ~3.0 |
| RTX 5080 | 360 W | ~4.0 |
| RTX 3090 | 350 W | ~2.8 |
| RTX 5090 | 575 W | ~3.2 |
Best-in-class tokens-per-watt in the 2026 lineup. The combination of Blackwell efficiency, moderate power envelope, and FP8 native support compounds the energy economics.
