The Coppermine core then moved in at 533 MHz and brought with it a veritable flood of models. Intel managed to extract up to 1100 MHZ from this core technology, bringing a total of 14 processors onto the market and causing confusion primarily among private customers, since it was often not clear to the non-techie which processor worked at which FSB speed.

The Tualatin core gave a new lease on life to the Pentium III architecture. With 512 kB cache and various improvements, the Tualatin was able challenge the Athlon. The Celeron also benefited from this core, albeit with only 128 kB cache, and also with only the usual 100 MHz FSB instead of a possible 133 MHz. But Intel was concentrating all its efforts on the Pentium 4 - knowing very well that the route via the highest possible clock speeds could ensure domination.

The 2 GHz Celeron is essentially similar to the 1.7 and 1.8 GHz models, only the structure has been reduced to 0.13 µm. As a result the operating voltage falls to 1.5 V.
