Motorola 68040 Clock Speed Commodore Amiga 4000

This article provides a definitive answer regarding the processing power of the Commodore Amiga 4000, specifically identifying the frequency of its central processing unit. Readers will learn the exact clock speed of the Motorola 68040 chip used in this system, alongside brief context about the machine’s release and architectural significance within the Amiga lineage.

The Commodore Amiga 4000, released in 1992, stands as one of the most powerful computers produced by Commodore International during the classic Amiga era. At the heart of this workstation-class machine lies the Motorola 68040 processor. This specific CPU operates at a clock speed of 25 MHz. This frequency allowed the Amiga 4000 to handle demanding tasks such as video production, 3D rendering, and complex multitasking more efficiently than its predecessors, such as the Amiga 3000 which utilized the 68030.

The 25 MHz Motorola 68040 was a significant upgrade because it included an integrated floating-point unit and both data and instruction caches on the die. This integration reduced latency and improved overall throughput compared to earlier configurations that required separate math coprocessors. While accelerator boards existed that could push this speed higher, the stock configuration found in the official Commodore Amiga 4000 desktop and tower models remained fixed at 25 MHz. This specification remains a key identifier for collectors and enthusiasts verifying the authenticity of original hardware today.
