I detected a sense of irritation at the discussion. You complained of a lack of professionalism and then you dissed the distinction between power and energy.
Yes, it could be assumed that the times were equal, I later stated that was the only case were your general statement about performance, power and energy, would be true.
Now you bring up processing speed! That brings with it all the same problems of your abstract 'performance' you brought up originally.
I really don't understand the nature of your comment.
Intel does not make displays, or touch screens, so they don't touch those pieces of a phone ... nor connectors, etc.
Last time I checked, Intel is trying to get involved in everything they can viably be involved in a phone with ... processor, memory, baseband, even an OS initiative with Samsung.
Short of building a phone, how are you expecting them to be involved?
At the end of the day, a phone (just like a computer), is nothing more than user interface, processor, memory and communications ... and something to power it.
Please explain how they have not left their old mentality and what they should be doing different?
In terms of a large battery, that means added cost, added expensive part that can fail, more weight, larger packaging, etc. .... all things consumers do not want.
The article was about comparing the processing power and power drain of two competing processors. Why would it discuss other areas of the phone design? We are engineers, I think we can figure out or research those areas separately.
The reality is that processor power still does come into play w.r.t. battery life. How many people hobble their phones as communications devices by limiting how often they check mail? That has nothing to do with the display, and everything to do with energy drain of RF and processor/baseband.
As people expect more out of phones/tablets, processor power becomes more, not less important.
I did not have to say time is equal, though I probably should have clarified that by performance, I meant processing speed, though I had thought that was understood.
As we were discussing the article and it showed both processing speed and current consumption (power) then we can easily calculate task energy which is what this article was really talking about .... equal performance (processing speed) at often significantly lower power leading to lower task energy.
Intel still treats the phone as a potential home for its processor, with the view that this home is focused on the processor, just like a PC or workstation or server. But a phone is a SYSTEM dedicated to displaying or broadcasting information, so other components besides CPU, GPU, memory are also important. So they haven't really left their old mentality. Which will be a problem for them.
Likely not a leap to expect the current drain was measured at the battery connection likely with very similar battery voltages. It would be difficult at best to isolate. Other power traces in a phone / tablet.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
