The first microprocessor based on Mendocino core. This processor is marked as "300A/66", the suffix "A" is used to distinguish it from older Covington Celeron 300/66 CPU. New feature in this Celeron was integrated 128 KB L2 cache running at the processor speed. Addition of the L2 cache was the main reason why the performance of this CPU was much better than performance of older Covington Celerons. Like the older Celeron 266, the Celeron 300A was a very good overclocker. It was possible to run the CPU at 450 MHz by using 100 MHz bus speed. |
