The next generation Celeron was the '' '[[Coppermine (microprocessor)|Coppermine]]-128' '' (sometimes known as the ''Celeron II''). These were a derivative of Intel's ''Coppermine'' [[Pentium III]] and were released on March 29, 2000.<ref>{{cite news |last=Hachman |first=Mark |title=Intel launches Celerons with SIMD instruction-set extensions |url=http://www.my-esm.com/digest/story/OEG20000329S0006 |publisher=My-ESM |date=March 29, 2000 |access-date=July 31, 2007 |archive-url=https://web.archive.org/web/20070927070052/http://www.my-esm.com/digest/story/OEG20000329S0006 |archive-date=September 27, 2007 |url-status=dead |df=dmy }}</ref> This Celeron used a Coppermine core with half of its L2 cache switched off, resulting in 128&nbsp;KB of 4-way associative on-chip L2 cache as on the Mendocino, and was initially likewise restricted to a 66&nbsp;MHz Front Side Bus speed. Despite the halved associativity on the L2 cache, which reduced hit rates compared to the full Coppermine design, it kept the 256-bit wide L2 cache bus, which meant an advantage compared to Mendocino and older Katmai/Pentium II designs, which all had a 64-bit datapath to their L2 caches.<ref>{{cite web|url=https://www.anandtech.com/show/519/5|title=Intel Celeron 600 "Coppermine128"|first=Anand Lal|last=Shimpi|website=anandtech.com|access-date=April 4, 2018}}</ref><ref>{{cite web|url=https://www.anandtech.com/show/568/2|title=Intel Celeron 700|first=Anand Lal|last=Shimpi|website=anandtech.com|access-date=April 4, 2018}}</ref> [[Streaming SIMD Extensions|SSE]] instructions were also enabled.

All Coppermine-128s were produced in the same [[FCPGA]] Socket 370 format that most Coppermine Pentium III CPUs used. These Celeron processors began at 533&nbsp;MHz and continued through 566, 600, 633, 667, 700, 733, and 766&nbsp;MHz. Because of the limitations of the 66&nbsp;MHz bus, there were diminishing returns on performance as clock rates increased. On January 3, 2001, Intel switched to a 100&nbsp;MHz bus with the launch of the 800&nbsp;MHz Celeron, resulting in a significant performance-per-clock improvement.<ref>{{cite news|last=Lal Shimpi| first=Anand| author-link=Anand Lal Shimpi | title=Intel Celeron 800: The first 100&nbsp;MHz FSB Celeron | url=http://www.anandtech.com/showdoc.aspx?i=1393&p=1 | publisher=[[AnandTech]]|date=January 3, 2001|access-date=July 30, 2007}}</ref> All Coppermine-128 CPUs from 800&nbsp;MHz and higher use the 100&nbsp;MHz front side bus. Various models were made at 800, 850, 900, 950, 1000, and 1100&nbsp;MHz.

In Intel's "Family/Model/Stepping" scheme, Coppermine Celerons and Pentium IIIs are family 6, model 8 and their Intel product code is 80526.
