I will use a simple example to answer you question Allen.Originally Posted by Audio Al
Opinions please re this
If a hifi ( CD ) player was made and first sold from 2003 and at the time was High end / cutting edge , Would that component still be HE / CE ? , or over time with technology moving on at a great rate and the evolution of chips would it now still be HE /CE , Also would older internal components still deteriorate as std models do
Caps need replacing ? along with resistsors / transistor's , dry joints on soldering etc ?
Even high end components change over time , don't they ???
In the early to mid 80's 286 and 386 computers with their green screens and MS-DOS were considered state of the art(SOTA), similarly the good old brick Nokia mobile phones (new tech at the time) was SOTA. Move forward only 10 years and 386's were defunct, 486 PCs had come and gone in 5 years, MS-DOS was dead really and no respecting PC did not run some version of MS - Windows, mobiles phones had shrunk in size, had better battery live and better facilities. Go on into the 00's and Intel chips had evolved through various versions of Pentium, by 97 Celeron was the new chip version, by early 2000's Pentium 4 emerged, Pentium Core came along in various guises and 64 bit processors. Along side this the iPhone came onto the scene which turned the mobile phone into a multi-media device, and all the competitors followed or the died.
So older components IMO would no longer be considered HE/CE although they were in their time. All chips deteriorate with time and use, whether processors of storage chips, they are effectively a very small but massive (in number) array of switches (on/off, 0 or 1 binary) with various other support circuits. So with use, and exposure to heat variations and atmospherics the switches decay and if it fails then so does the processor or SSD. I have tried to explain in easy to understand terms. This may help explain the sophistication https://www.extremetech.com/extreme/...microchips-are
