Performance difference between the 3 available CPU

hello everyone,

think thread 3 cpu options available important there lot of speculation on if little boys able sustain performances.

first here 3 cpu used apple.


wee can see, frequency , tdp selectable manufacturer, turbo boost chip independant.
@ end there 2 difference:

• with entry level, h5300 underclocked in comparison 2 other versions
• with cto option, chip has 2 security features may not been use apple (so point irrelevant).
• the entry level (core-m 5y31) has base frequency of 900mh tdp of 4.5w, has max base frequency of 1.1ghz (the base frequency of macbook) , inherit max base tdp of 6w. thus, the entry level cpu might produce heat (as other run on "mid-tdp" @ 5w).

let's talk how processor behave:
cpu not fan-cooled means dissipation made metal body (alu?) , thus, low tdp of 5w, case might go bit hot when there heavy tasks.
other point because of cooling method, cpu not able intensive task in turbo boost long period of time, super capable of everyday task. (internet, office processing, photo, video playback etc.)

on rmbp tried play heavy mkv see cpu usage: played 3 30gb+ movies @ same time , i5 2.6 whas not used @ 20%.
however, main concern when watching streaming videos in hd on verge: player in flash , simple hd video using 60-70% of cpu. rmbp super hot... in later scenario, core m might want go in turbo boost play give bad user experience computer go bit hot, , chip might not able achieve smooth playback experience?

should 1.3ghz cto? in opinion no:
normal price cto cpu between 83€ small bump , 190€ large 1 (in france @ least). apple following rule , ask around 100$ option.
when looking @ extremly few benchmark available, gain of 100mhz less 10% , under full cpu load! explained, cpu not able sustain full load long time (1 minute max if optimistic) , benefits not being seen in normal usage.
rather recommend people want best "bang buck" stay high non-cto model (1.2/512gb). choice!

hope post can create constructive discussion cpu capabilities main concern , have passed last few hours on reading products review using core m chips.

edited add third point list.

 

wouldn't higher cpu's cause more heat?
