A small corner of the AMD 486DX2 microprocessor die is revealed in the digital image presented below, which is enhanced by oblique illumination with red and blue filters. Portions of the die that feature high relief and are perpendicular to the red gel filter appear bright red in the image, while those details that are perpendicular to the blue gel are blue.

Chipmaker Advanced Micro Devices (AMD) continued to manufacture Intel-designed chips following the 286, 386, and 486DX processors, subsequently releasing the AMD 486DX2 in 1992 and the 486DX4 in 1994. The introduction of internal clock doublers and triplers expanded the 486 family of microprocessors, thus creating the much faster DX2s and DX4s. The AMD 486DX2 microprocessor features a built-in system management mode (SMM) power setting and write-back capability for the primary cache, which boosts performance.
