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.
