Intel was well aware of the poor reputation of the original Celeron and determined not to make the same mistake twice, with the result that the new Mendocino core Celeron was a good performer from the outset. Indeed, most industry analysts regarded the first Mendocino-based Celerons as too successful - performance was sufficiently high to not only compete strongly with rival parts, but also to attract buyers away from Intel's high-profit flagship, the Pentium II.

The key to the new Celeron's performance is cache. Where the old model had no secondary cache at all, the new part includes 128KB of L2 cache as part of the chip itself. Otherwise, it is identical. With a total of 19.2 million transistors (including cache) on a single chip, the Mendocino Celeron was difficult and expensive to manufacture, but Intel managed a flawless execution of an ambitious project.

The first Mendocino-core Celeron was clocked at a then-modest 300MHz but was almost twice as fast as the old cacheless Celeron at the same clockspeed. To distinguish it from the old model, Intel called it the 300A. Although the other Mendocino Celerons (this 333MHz part, for example) did not have an A appended, some people call all Mendocino processors Celeron-A regardless of speed.
