Although they have only been around for just under three years, Intel is sending a handful of Kaby Lake-U Refresh CPUs off to early retirement. The chips in question are the 8th Gen Intel Core i5-8250U, i5-8350U, i7-8550U and i7-8650U.
Intel introduced these chips in August 2017, and they were among the first chips from Intel to bring four CPU cores to mobile platforms. This means that although they were a refresh of the 7th Generation Kaby Lake CPUs, they did offer significant performance increases over their previous-generation counterparts.
Despite a doubling of the core count, however, the chips kept the same TDP as their predecessors of 15W.
|CPU||Cores/Threads||Base Clock||Turbo Frequency|
|Intel Core i5-8250U||4 / 8||1.60 GHz||3.40 GHz|
|Intel Core i5-8350U||4 / 8||1.70 GHz||3.60 GHz|
|Intel Core i7-8550U||4 / 8||1.80 GHz||4.00 GHz|
|Intel Core i7-8650U||4 / 8||1.90 GHz||4.20 GHz|
All the aforementioned CPUs went into their discontinuance program as of yesterday. The final order date for the i7-8650U and i5-8350U's is October 23, 2020 with and a final shipment date of April 9, 2021. The i7-8550U and i5-8250U will see end-of-life slightly sooner on July 24, 2020 with a final shipment date of January 22, 2021.
Meanwhile, only two Kaby Lake-U Refresh processors remain on the market: the Pentium Gold 4417U and Celeron 3867U. However, Intel introduced these chips in 2019, so they still have some time to go before getting the axe.
