利用 1 MW = 1,000,000 J/s 且 1 焦耳 = 0.000239 食物卡路里，我们可以把功率效率换算成每卡路里的 token 数： 7,368 tok/s/MW = 0.007368 tok/J 0.007368 ÷ 0.000239 = 30.8 输出 tok/卡路里 鉴于普通人说话速度约为 ~3.3 tok/s，而大脑消耗约 ~20 W： 3.3 tok/s ÷ 20 J/s = 0.165 tok/J 0.165 ÷ 0.000239 = ~690 输出 tok/卡路里 这使得人类说话的能量效率大约是该并发 1 B300 配置的 22 倍！（2/4）
Using the fact that 1 MW = 1,000,000 J/s and 1 joule = 0.000239 food Calories, we can convert power efficiency into tokens per Calorie:
7,368 tok/s/MW = 0.007368 tok/J
0.007368 ÷ 0.000239 = 30.8 output tok/Calorie
Given that an average human speaks at ~3.3 tok/s while the brain consumes ~20 W:
3.3 tok/s ÷ 20 J/s = 0.165 tok/J
0.165 ÷ 0.000239 = ~690 output tok/Calorie
That makes human speech roughly 22× more energy-efficient than this concurrency 1 B300 configuration! (2/4)
