The SPECpower reports power consumption of servers at different workload levels, divided into 10% increments, over a period of time.
| The table shows the SPECpower_ssj2008 running on a dual socket 2.2 GHz Intel Xeon Platinum 8276L with 192 GiB of DRAM and one 80 GB SSD disk. |

Once again, to simplify the marketing of computer, SPEC boils these numbers down to a single number, called “overall ssj_ops per watt.” The formula for this single summarizing metric is
overall ssj_ops per wattwhere
= ( Σ ssj_opsi ) / ( Σ poweri ), where i = 0 .. 10
ssj_opsiis performance at each 10% increment, andpoweriis power consumed at each performance level.
overall ssj_ops per watt
= ( Σ ssj_opsi ) / ( Σ poweri ), where i = 0 .. 10
= ( 4864136+4389196+3905724+3418737+2925811+ 2439017+1951394+1461411+974045+485973+0 ) / ( 347+312+278+241+212+183+160+141+128+115+48 )
= 26815444 / 2165 = 12,385
