Core Viewpoint - The article discusses the historical significance of AMD's Am9080 processor, which was a reverse-engineered clone of Intel's 8080, highlighting its impact on AMD's growth in the CPU market and the financial success it brought to the company [4][7]. Group 1: Historical Context - AMD's Am9080 was developed through reverse engineering of Intel's 8080, leading to a licensing agreement between the two companies to avoid legal disputes [4][8]. - The Am9080 was first produced in 1975, with AMD manufacturing costs at $0.50 per unit and selling prices reaching $700, particularly to military clients [7][8]. Group 2: Technical Specifications - The Am9080 had multiple versions with clock speeds ranging from 2.083 MHz to 4.0 MHz, showcasing AMD's advanced N-channel MOS manufacturing process [10]. - The chip's design was more compact than the Intel 8080, allowing for higher clock frequencies, with the Intel 8080 never exceeding 3.125 MHz [10]. Group 3: Business Agreements - In 1976, AMD signed a cross-licensing agreement with Intel, which allowed AMD to become a "second source" for Intel's products, facilitating future collaborations and product developments [8]. - The agreement included a payment of $25,000 to Intel and an annual fee of $75,000, which also absolved both companies from past infringement liabilities [8].
