[Off-topic] Assessing CPU and storage power load

[Max Pyziur <pyz@xxxxxxxxx>]

Greetings, 

 

I'm trying to work to compute some processing metrics (one computation requires X amount of power) for CPUs and storage

 

Looking through this article (https://www.halfhill.com/byte/1998-3_deschutes.html) I see the last sentence of the fifth paragraph read, "Power consumption is only 23.7 W at 333 MHz, compared to 43 W for a 300-MHz Klamath."

 

Looking at Dell's specs for the processor (Intel(R) Core(TM) i7-8665U (8) @ 4.80 GHz) on my workhorse laptop (https://www.dell.com/support/manuals/en-us/xps-13-9380-laptop/xps-13-9380-setupandspecs/processors?guid=guid-d9ac4f8f-9667-43b7-ba1b-9610f8f0e613&lang=en-us), I see 15 watts.

 

But the power consumption isn't "apples to apples" in the sense of number of work units per power consumption

 

The same with harddrives (legacy spinning ones to the current SSDs).

 

For my Samsung 950 PRO NVMe M.2 512GB I see:
    Power Consumption (W)
    ***Average: 5.7 Watts, Idle : 70mW
    * Actual power consumption may vary depending on system hardware & configuration

 

with a variety of metrics describing throughput of 

    Interface:  PCIe 3.0 x4 (up to 32Gb/s) NVMe 1.1

    Sequential Read Speed: Up to 2,500 MB/sec Sequential Read**

    Sequential Write Speed: Up to 1,500 MB/sec Sequential Write**

 

For my circa 2006 Hitachi HDS721050CLA660 500GB HDD I see read speads of 
Maximum interface speed    600 MB/s
Maximum buffered read speed    294 MB/s
Maximum read speed    152 MB/s

 

I don't see any power metric for the Hitachi. 

 

Thank you in advance for any guidance here.

 

Max
