The IBM Personal Computer 300GL is a model designation that actually covered a pretty wide variety of different models. Machines were built with the 300GL designation with CPUs ranging from Pentium MMX to Pentium IIIs and everything in between. This particular one came with a 300 MHz Celeron (Mendocino). The Mendocino Celerons were essentially Pentium IIs with a small, on die cache. The cache was less than the Pentium IIIs of the time (128K vs. 256K) but it ran at full clock speed instead of half speed. The Celerons were also missing the new SSE instructions that Pentium IIIs had but they were highly overclockable. For instance, a 300 MHz Celeron could typically be easily overclocked to 450 MHz by simply changing the bus speed from 66 MHz to 100 MHz.
