INTEL vs. AMD

Intel
Intel (Integrated Electronics Corporation) is the world's largest CPU manufacturer. It was founded in 1968 and is based in Santa Clara, California (US). Intel is the creator of the x86 CPU architecture which is now used in the majority of PCs (and since 2006 Macs as well). Intel's domination in the x86 CPU market led to charges of antitrust violations in US, EU, Japan and South Korea over the years.

AMD

AMD (Advanced Micro Devices) was founded in 1969 and is based in Sunnyvale, California (US). It is the second largest supplier of x86 architecture CPUs and, after a merger with ATI in 2006, the third largest manufacturer of GPUs (after Intel and nVidia). It is considered the underdog of the CPU market due to revenue and market share several times smaller than Intel's (19% in 2009 Q4 vs Intel's 80%).
