There were many users who left out Slot 1 as a processor platform for reasons of cost. Because as early as 1998 the next development was ready: Socket 370, for which there were two case variations - the PPGA and the FC-PGA. The PPGA was predominantly used in OEM systems because it was cheaper to manufacture. In the aforementioned, only the Celeron was used in the plastic package; the Pentium III CPUs came in the more expensive FC-PGA package. And there was one exception: The Celeron with Mendocino core could be used in both sockets. But there was also help: using an adapter, the PPGA CPUs could also be used in Slot 1; for the FC-PGA version there was no adapter.

For a long time, the CPUs for Slot 1 and Socket 370 were being made and sold simultaneously, although the Pentium III (Coppermine) from 1 GHz clock speed and up met its end in Slot 1.
The last core for Socket 370 was the Tualatin, which meant a transformation (shrink) from 180 nm to 130 nm. The Pentium III-S was made with up to 1.4 GHz and a 512 kB L2 cache. Moreover, this core had data prefetch expansions, which were the forerunner of the micro-ops of today's Pentium 4.
