Intel announced that the 8th generation Core U-Series low-power processor, codenamed Kaby Lake-U Refresh, was in the process of de-listing, just two-and-a-half years after their release. In August 2017, Intel officially released the i5-8250U/8350U, i7-8550U/8560U processor.
Although they are only an upgrade to the seven-generation Core Kaby Lake, the manufacturing process is still 14nm, but this is the first time Intel has brought four core eight threads to a thin platform with a maximum acceleration frequency of 4.2GHz and thermal design power consumption at 15W.
the i5-8250U, i7-8550U quickly became the standard for a new generation of lightweight books, with products all over the street.
Due to product positioning issues, the Core U series did not have a ninth-generation sequence and then went straight into the tenth generation, including the 10nm Ice Lake-U and 14nm Comet Lake-U, which were less frequent, while the latter expanded to six core twelve threads.
According to the latest notice, the i5-8250U and i7-8550U will stop accepting orders after July 24, 2020 and shipping on January 22, 2021;
It is not uncommon for such a successful product to retire so quickly and stay for up to a year.
In fact, the Kaby Lake-U Refresh family also has two low-end products, the Pentium Gold 4417U and the Celeron 3867U, both released early last year, just over a year later, and will still be there for some time.
However, these two product specifications are very low, are dual core, Celeron 3867U does not support hyperthreading, frequency fixed at 2.3GHz, 1.8GHz, three-level cache only 2MB, nuclear display is only UHD 610, thermal design power consumption is 15W, so basically no product adoption, no sense of existence.
