Celeron 533A, the first FC-PGA Celeron, was running at the same frequency as the fastest PPGA Celeron processor. Having the same L2 cache size and running at the same bus speed, performance-wise this processor was not very different from PPGA Celeron. The only exception was increased performance in applications utilizing SSE instructions. The suffix "A" in "533A" was used to distinguish the new Celeron CPU from older PPGA processor.

Coppermine Celeron processors were produced in Flip-Chip Ping Grid Array (FC-PGA) package. In this type of package the microprocessor core was mounted on the printed circuit board upside down. Be careful when installing the heatsink as it is possible the damage the core. For example, this specific processor has lower-right corner of the core substrate damaged. If the damage is minor the processor may still work.

While all Mendocino Celerons required 2V core voltage, many Coppermine Celerons were produced with a few different core voltage requirements. This microprocessor, RB80526RX600128, could have 1.5, 1.7 and 1.75 Volt core. Faster processors (up to 850 MHz) were produced with core voltages ranging from 1.65 to 1.75 Volt, and top of the line Coppermine Celerons required 1.75 Volt core. Even at 1.75V Coppermine Celerons were much less power hungry than Mendocino Celerons. For example, Celeron 600 processor has the same maximum power dissipation as Celeron 366 or Celeron 400.

Almost all Celeron processors, with the exception of engineering samples and earlier chips, didn't have part number printed on the chip. Instead, Intel marked the chips with the most important parameters such as CPU frequency, bus frequency and core voltage. While this particular processor has part number RB80526RX700128, the actual markings on the chip are 700/66/1.75V. As with all other Intel chips, when you're in doubt use Intel s-spec number to find out CPU parameters. S-spec number is a 5-letter code that starts with 'S' for production chips, or from 4, 5 or 6 letter code starting with 'Q' for sample chips.

Celeron 800 is the first Celeron processor with 100 MHz bus speed. 50% increase in bus speed frequency helped Intel to better compete with AMD Duron CPUs, but even after this FSB increase the Celeron 800 was still slightly slower than Duron 800 in many applications.
