Intel Pentium III 400 - 80525PZ400512


400 MHz (133 MHz bus)
512 KB L2 cache
Single Edge Contact cartridge 2 (slot 1)

Produced later than the DC1EC501A400 CPU this engineering sample has very significant feature - 133 MHz front side. Increasing front side bus speed from 100 MHz to 133 MHz allowed to increase processor performance by 5% - 10% on average.

It's worth to note that this processor was manufactured almost 11 months before the release of first Katmai processors with 133 MHz bus speed.
