Is that total power, or power per GFLOP?
- valarauca1 10y agoAre you seriously asking me to do division for you? Do you own a calculator, cellphone or computer? Or are you actually that helpless? AMD RX 480 has 5.8TFLOPS @$200 ($37/TFLOP) @231Watt Peak (2.5GFLOPS/Watt) Nvidia GTX1080 8.9TFLOPS @$600 ($67/TFLOP) @318Watt Peak (2.8GFLOPS/Watt) See Furmark benchmark for wattage values [1] Typical KW-H in the US $0.12KW-H [2]. So the delta-cost of GTX1080 vs RX480 will be mitigated by GFLOPS/Watt efficiency savings in 4 years, 4 months. Which on a typical 2, 3, or even 4 year hardware replacement cycle the extra cost will NEVER be re-couped.
