Intel vs AMD

For years, Intel utilized a highly successful "tick-tock" manufacturing strategy where a "tick" represented shrinking the chip's transistor size, and a "tock" represented a new microarchitecture. This relentless cycle allowed Intel to maintain a massive performance and efficiency lead over AMD during the Core 2 Duo and early Core i-series eras.

Released in 2017, the AMD Ryzen line, based on the new Zen architecture, finally offered competitive multi-core performance at incredibly aggressive prices. This forced Intel to abruptly abandon their complacent quad-core consumer lineups and rapidly release 6-core, 8-core, and higher processors to stay competitive in the desktop market.

In 2003, AMD released the Athlon 64, which was the first mainstream 64-bit consumer processor, beating Intel to the market by a significant margin. This processor severely embarrassed Intel, whose competing Pentium 4 "Prescott" architecture suffered from massive heat issues and inefficiency.

Intel historically operates as an Integrated Device Manufacturer (IDM), meaning they design and manufacture their own chips in their own fabrication plants. Conversely, AMD spun off its manufacturing arm into GlobalFoundries in 2009, transitioning to a "fabless" model where they design chips but rely on third-party foundries like TSMC to print them.
