Okay, but let's know that my current i7 claims only 2.4 gigahertz clock speed on average but may go into faster speed as needed by turbo mode.  Your post mentions Turbo mode.  I am ignorant to that mode.  The usage I do with this older i7 7500 rarely even turns the fan on in the laptop so it has been sufficient.  Once in a while the fan will come on.  I figure that is some heavy duty download and automatic adjustments Windows 10 is performing.  I am not looking to put a new CPU in this laptop but to get a new device that is as least as fast as this one is.  I am wondering if average speed of the newer Inspirons with 11th gen i5 are equal or above in processing speed to my older 7th gen i7.  I recall a turbo setting I have on this i7 but it does not kick in till the going gets rough with big graphics files as in processing large RAW photos etc. which I do not need. I just need basics of streaming HD 1080 video from wifi, email, and searching the web for info from YouTube, loading graphics and text from public library sources, and text based sources.  I will look at your links but the Turbo confuses me.  Those speeds are impressive but I don't know if a stock i5, Inspiron would be in "Turbo," mode continuously.  I am hoping that the lower priced i5's at gen 11 are just as fast or faster than my gen 7 i7 which it is looking like they probably are although I can't get a simple straight answer to that question....yet. When I see the specs on the current 11th gen i5's it looks good.  I am asking advice here to back up that claim from an experienced user that yes, moving down from i7 to i5 with current machines will at least keep me at the speed I have with my older i7. Hope that makes sense.  Bottom line question:  "Is an 11th gen i5, as fast or faster in regular mode (not turbo) than a 7th gen i7?
My 5 year old i7 7500 Inspiron is computing fine, but it has a defective charging port.  I am thinking the cost of a fix may be better spent on a new laptop.  Its 7th gen i7 7500 has been declared not fit for Windows 11.  A new battery and charger did not help.  The charging port is damaged due to the pressure of the 2 in 1 screen pulling apart the left hand corner of the base of the laptop making the charging port not connect well to the plug of the charger.  The plug will easily fall out.  I should have returned it on warranty, but I have gotten by yet it gets worse. Looking at new Inspirons, my question is: Can I expect the 11th gen i5 to be as fast as the 7th gen i7 I have? The Dell site has an Inspiron 14, no touch screen, which is fine because I am done with this 2 in 1 touch screen. I never used that feature.  The listing at Dell is a 11th gen i5.  I am more concerned about speed than size of the SSD or RAM.  So, I wonder if that Inspiron 14 would be at least as capable as my 5 year old 7th gen i7 7500.  And, hopefully it will have no charging port issue.  My other choice would be go Mac Air...if my files will convert.  That would be a return to Mac after 25 years of Microsoft OS products.
What to expect from 11th gen i5 processor.
