Intel introduced the 486 microprocessor in 1989, and in 1990 established a second design team, designing the processors code-named "P5" and "P6" in parallel and committing to a major new processor every two years, versus the four or more years such designs had previously taken. Engineers Vinod Dham and Rajeev Chandrasekhar (Member of Parliament, India) were key figures on the core team that invented the 486 chip and later, Intel's signature Pentium chip. The P5 project was earlier known as "Operation Bicycle," referring to the cycles of the processor through two parallel execution pipelines. The P5 was introduced in 1993 as the Intel Pentium, substituting a registered trademark name for the former part number (numbers, such as 486, cannot be legally registered as trademarks in the United States). The P6 followed in 1995 as the Pentium Pro and improved into the Pentium II in 1997. New architectures were developed alternately in Santa Clara, California and Hillsboro, Oregon.
The Santa Clara design team embarked in 1993 on a successor to the x86 architecture, codenamed "P7". The first attempt was dropped a year later but quickly revived in a cooperative program with Hewlett-Packard engineers, though Intel soon took over primary design responsibility. The resulting implementation of the IA-64 64-bit architecture was the Itanium, finally introduced in June 2001. The Itanium's performance running legacy x86 code did not meet expectations, and it failed to compete effectively with x86-64, which was AMD's 64-bit extension of the 32-bit x86 architecture (Intel uses the name Intel 64, previously EM64T). As of 2012, Intel continues to develop and deploy the Itanium; known planning continues into 2014.
The Hillsboro team designed the Willamette processors (initially code-named P68), which were marketed as the Pentium 4.
In June 2011, Intel introduced the first Pentium mobile processor based on the Sandy Bridge core. The B940, clocked at 2 GHz, is faster than existing or upcoming mobile Celerons, although it is almost identical to dual-core Celeron CPUs in all other aspects. According to IHS iSuppli's report on September 28, 2011, Sandy Bridge chips have helped Intel increase its market share in global processor market to 81.8%, while AMD's market share dropped to 10.4%.
Intel planned to introduce Medfield a processor for tablets and smartphones to the market in 2012, as an effort to compete with ARM. As a 32-nanometer processor, Medfield is designed to be energy-efficient, which is one of the core features in ARM's chips.
At the Intel Developers Forum (IDF) 2011 in San Francisco, Intel's partnership with Google was announced. By January 2012, Google's Android 2.3 will use Intel's Atom microprocessor.
