Power to computing can be measured in terms of a typical performance metric per Watt & for example FLOPS / Watt or input / output per second / Watt for computing and I / O respectively .

计算功率可采用标准的每瓦特性能形式来度量&例如，FLOPS/Watt或分别用于计算和I/O的 每秒/ 瓦特输入/输出。

Figure13d shows the performance per watt by taking the number of requests per second divided by the average power consumed .

图13d通过用 每秒请求数除以平均电能消耗显示“性能/ 瓦特”。
