The original Athlon ( now called Athlon Classic ) was the first seventh-generation x86 processor and, in a first, retained the initial performance lead it had over Intel's competing processors for a significant period of time.

The Intel MCS-51 ( commonly referred to as 8051 ) is a Harvard architecture, single chip microcontroller ( µC ) series which was developed by Intel in 1980 for use in embedded systems .< ref > John Wharton: An Introduction to the Intel MCS-51 < sup > TM </ sup > Single-Chip Microcomputer Family, Application Note AP-69, May 1980, Intel Corporation .</ ref >< ref > John Wharton: Using the Intel MCS-51 < sup > TM </ sup > Boolean Processing Capabilities, Application Note AP-70, May 1980, Intel Corporation .</ ref > Intel's original versions were popular in the 1980s and early 1990s.

Intel's original MCS-51 family was developed using NMOS technology, but later versions, identified by a letter C in their name ( e. g., 80C51 ) used CMOS technology and consumed less power than their NMOS predecessors.

Fab 7, Intel's original Rio Rancho plant, closed in 2002 but is being converted into a test facility.

* Rockwell, the original name for Intel's microarchitecture that is due to be out in 2014 ( now called Broadwell )

The original Intel 8086 ( Intel's first 16-bit microprocessor ) was an exception to this rule which implemented a segmented memory model, because it provided an easy form of memory management with flexible page boundaries for early operating systems such as DOS and allowed access to an address space greater than what would otherwise be available with its 16-bit addressing.

A similar phenomenon has developed in Intel's x86 assembly language – because of the support for various sizes ( and backward compatibility ) in the instruction set, some instruction mnemonics carry " d " or " q " identifiers denoting " double -", " quad -" or " double-quad -", which are in terms of the architecture's original 16-bit word size.

While its original version was related to Intel's DVI video stream format, a hardware-only codec for the compression of television-quality video onto compact discs, Indeo was distinguished by being one of the first codecs allowing full-speed video playback without using hardware acceleration.

In 1990, NCR introduced the System 3000, a seven-level family of computers based on Intel's 386 and 486 CPUs.

Focused on removing potential competitors, Intel spent many years in legal battles with Cyrix, consuming Cyrix financial resources, claiming that the Cyrix 486 violated Intel's patents, when in reality the design was proven independent.

The follow-on 1997 Cyrix-Intel litigation was the reverse: instead of Intel claiming that Cyrix 486 chips violated their patents, now Cyrix claimed that Intel's Pentium Pro and Pentium II violated Cyrix patents — in particular, power management and register renaming techniques.

The settlement didn't say whether the Pentium Pro violated Cyrix patents or not ; it simply allowed Intel to carry on making them either way — exactly as the previous settlement sidestepped Intel's claim that the Cyrix 486 violated Intel patents.

With better performance in most applications than an Intel Pentium processor at 75 MHz, the Cyrix Cx5x86 filled a gap by providing a medium-performance processor option for 486 Socket 3 motherboards ( which are incapable of handling Intel's Pentium CPUs, apart from the Pentium Overdrive ).

Intel's expensive Pentium Overdrive for 486 systems was a troublesome CPU, with many compatibility issues, and so was not used.

Its use in personal computers became widespread with the introduction of Intel's Pentium processor to " support the more efficient write-back cache in addition to the write-through cache previously used by the Intel 486 processor ".

Intel beat AMD to market by nearly four years, but AMD priced its 40 MHz 486 at or below Intel's price for a 33 MHz chip, offering about 20 % better performance for the same price.

While competing 486 chips, such as those from Cyrix, benchmarked lower than the equivalent Intel chip, AMD's 486 matched Intel's performance on a clock-for-clock basis.

As prices on Intel's 486 line fell, Cyrix found it more and more difficult for its 486SLC and DLC CPUs to compete and had to release a fully pin-compatible version of the 486SX and DX in 1993.

The Athlon Classic is a cartridge-based processor, named Slot A and similar to Intel's cartridge Slot 1 used for Pentium II and Pentium III.

The 386 was for a time only available from Intel, since Andy Grove, Intel's CEO at the time, made the decision not to encourage other manufacturers to produce the processor as second sources.

AMD introduced its compatible Am386 processor in March 1991 after overcoming legal obstacles, thus ending Intel's monopoly on 386-compatible processors.

With the buyout of NexGen, AMD was able to come back into the game with a processor that could perform competitively with Intel's Pentium II.

Intel's Larrabee multicore architecture project uses a processor core derived from a P5 core ( P54C ), augmented by multithreading, 64-bit instructions, and a 16-wide vector processing unit.

Intel's low-powered Bonnell microarchitecture employed in Atom processor cores also uses an in-order dual pipeline similar to P5.

Despite many successes, RISC has made few inroads into the desktop PC and commodity server markets, where Intel's x86 platform remains the dominant processor architecture.

Sun products included computer servers and workstations built on its own RISC-based SPARC processor architecture as well as on x86 based AMD's Opteron and Intel's Xeon processors ; storage systems ; and a suite of software products including the Solaris operating system, developer tools, Web infrastructure software, and identity management applications.

Introduced in 2004 along with the Prescott revision of the Pentium 4 processor, SSE3 added specific memory and thread-handling instructions to boost the performance of Intel's HyperThreading technology.

Recent versions support the HP 9000 series of computer systems, based on the PA-RISC processor architecture, and HP Integrity systems, based on Intel's Itanium architecture.

In the late 1990s, the idea of executing instructions from multiple threads simultaneously, known as simultaneous multithreading, had reached desktops with Intel's Pentium 4 processor, under the name hyper threading.

The Triton II ( Official name 82430HX ) was a version of Intel's Triton processor chipset with all the features of the 82430FX ( Triton I ) plus support for ECC, parity RAM, two-way SMP, USB, and then current PCI to improve speed.

" Another major concern was that Intel's existing customer base purchased their memory chips for use with their own processor designs ; if Intel introduced their own processor, they might be seen as a competitor, and their customers might look elsewhere for memory.

The processor was designed using nMOS circuitry and the later " H " versions were implemented in Intel's enhanced nMOS process called HMOS, originally developed for fast static RAM products.

* Intel MIC ( Many Integrated Core ), Intel's many-core processor architecture

The XScale core is utilized in the second generation of Intel's IXP network processor line, while the first generation used StrongARM cores.

On June 27, 2006, the sale of Intel's XScale PXA mobile processor assets was announced.

Increasing processor power consumption led ultimately to Intel's May 2004 cancellation of its Tejas and Jayhawk processors, which is generally cited as the end of frequency scaling as the dominant computer architecture paradigm.

The most controversial of these features was the " branch-prediction " feature, which was enabled in the benchmarks results on the company website when comparing the chip to Intel's Pentium processor.

The letters PR stood for " Performance Rating ", but many people mistakenly thought it stood for " Pentium Rating ", as the PR was often used to measure performance against Intel's Pentium processor.

Meanwhile, the MediaGX faced pressure from Intel's and AMD's budget chips, which also continued to get less expensive while offering much greater performance.

This decision was ultimately crucial to Intel's success in the market.

VLB importantly offered an affordable high speed interface for consumer systems, as only by 1996 was PCI commonly available outside of the server market via the Pentium and Intel's Triton chipset.

* High performance CPUs: while RISC in its early days ( early 1980s ) offered roughly an order-of-magnitude performance improvement over CISC processors of comparable cost, one particular family of CISC processors, Intel's x86, always had the edge in market share and the economies of scale that this implied.

nCUBE was founded in 1983 in Beaverton, Oregon by a group of Intel employees frustrated by Intel's reluctance to enter the parallel computing market, though Intel released their iPSC / 1 in the same year as the first nCUBE was released.

During his tenure as CEO, Grove oversaw a 4, 500 % increase in Intel's market capitalization from $ 4 billion to $ 197 billion, making it the world's 7th largest company, with 64, 000 employees.

Intel's third revision Pentium 4, using the " Prescott " core, was infamous for being one of the hottest-running CPUs on the market.

However programs needed to be specifically tailored for the new instructions and despite beating Intel's SSE instruction set to market, 3DNow achieved only limited popularity.

In 1996 the two companies agreed to a two-year continuation of the agreement in which Trend was allowed to globally market the ServerProtect product under its own brand alongside Intel's LANDesk brand.

Products in the form of motherboards appeared on the market in June 2007 based on Intel's P35 " Bearlake " chipset with DIMMs at bandwidths up to DDR3-1600 ( PC3-12800 ).
