The AGP slot first appeared on x86 compatible system boards based on Socket 7 Intel P5 Pentium and Slot 1 P6 Pentium II processors.

One limitation ( also afflicting the Intel Pentium III ) is that SRAM cache designs at the time were incapable of keeping up with the Athlon's clock scalability, due both to manufacturing limitations of the cache chips and the difficulty of routing electrical connections to the cache chips themselves.

Just as Intel had done when they replaced the old Katmai-based Pentium III with the much faster Coppermine-based Pentium III, AMD replaced the 512 kB external reduced-speed cache of the Athlon Classic with 256 kB of on-chip, full-speed exclusive cache.

* Intel Pentium III, Pentium 4, and Celeron

The Intel P5 Pentium had two superscalar ALUs which could accept one instruction per clock each, but its FPU could not accept one instruction per clock.

This trend culminated in large, power-hungry CPUs such as the Intel Pentium 4.

However, it continued to use native x86 execution and ordinary microcode only, like Centaur's Winchip, unlike competitors Intel and AMD which introduced the method of dynamic translation to micro-operations with Pentium Pro and K5.

With regard to internal caches, it has a 16-kB primary cache and is socket-compatible with the Intel P54C Pentium.

The 6x86 and 6x86L weren't completely compatible with the Intel P5 Pentium instruction set and is not multi-processor capable.

Cyrix used a PR rating ( Performance Rating ) to relate their performance to the Intel P5 Pentium ( pre-P55C ), because a 6x86 at a lower clock rate outperformed the higher-clocked P5 Pentium.

Therefore, despite being very fast clock by clock, the 6x86 and MII were forced to compete at the low-end of the market as AMD K6 and Intel P6 Pentium II were always ahead on clock speed.

The Intel P5 Pentium generation was a superscalar version of these principles.

Later, with the introduction of the Pentium brand, Intel began branding its chips with words rather than numbers.

More powerful 486 iterations such as the OverDrive and DX4 were less popular ( the latter available as an OEM part only ), as they came out after Intel had released the next generation P5 Pentium processor family.

It was marketed as a product which could perform as well as its Intel Pentium II equivalent but at a significantly lower price.

However, as Intel quickly released faster versions of their Pentium class CPUs, Microsoft Windows NT v4. 0 dropped support for anything but Intel and Alpha.

* 1993 – The Intel Corporation ships the first Pentium chips ( 80586 ), featuring a 60 MHz clock speed, 100 + MIPS, and a 64 bit data path.

Later, release 3. 0 leveraged the enhancements of newer Intel 486 and Intel Pentium processors — the Virtual Interrupt Flag ( VIF ), which was part of the Virtual Mode Extensions ( VME )— to solve this problem.

Additions included DSP instructions and an implementation of the extended MMX subset of Intel SSE.

Intel Pentium MMX microarchitecture.

MMX is a SIMD instruction set designed by Intel, introduced in 1997 for the Pentium MMX microprocessor.

The MMX instruction set was developed from a similar concept first used on the Intel i860.

MMX is a single instruction, multiple data ( SIMD ) instruction set designed by Intel, introduced in 1996 with their P5-based Pentium line of microprocessors, designated as " Pentium with MMX Technology ".

MMX is a processor supplementary capability that is supported on recent IA-32 processors by Intel and other vendors.

MMX is officially a meaningless initialism trademarked by Intel ; unofficially, the initials have been variously explained as standing for MultiMedia eXtension, Multiple Math eXtension, or Matrix Math eXtension.

AMD, during one of its numerous court battles with Intel, produced marketing material from Intel indicating that MMX stood for " Matrix Math Extensions ".

In 1997, Intel filed suit against AMD and Cyrix Corp. for misuse of its trademark MMX.

AMD and Intel settled, with AMD acknowledging MMX as a trademark owned by Intel, and with Intel granting AMD rights to use the MMX trademark as a technology name, but not a processor name.

iwMMXt stands for " Intel Wireless MMX Technology ".

Processors that used Socket 7 are the AMD K5 and K6, the Cyrix 6x86 and 6x86MX, the IDT WinChip, the Intel P5 Pentium ( 2. 5 – 3. 5 V, 75 – 200 MHz ), the Pentium MMX ( 166 – 233 MHz ), and the Rise Technology mP6.

In practice it is typical to use instructions which will execute on anything later than an Intel 80386 ( or fully compatible clone ) processor or else anything later than an Intel Pentium ( or compatible clone ) processor but in recent years various operating systems and application software have begun to require more modern processors or at least support for later specific extensions to the instruction set ( e. g. MMX, 3DNow !, SSE / SSE2 / SSE3 ).

Early video chipsets featuring AGP support included the Rendition Vérité V2200, 3dfx Voodoo Banshee, Nvidia RIVA 128, 3Dlabs PERMEDIA 2, Intel i740, ATI Rage series, Matrox Millennium II, and S3 ViRGE GX / 2.

Later, the Intel Pentium II, and Intel Pentium III processors allowed dual CPU systems, except for the respective Celerons.

This was followed by the Intel Pentium II Xeon and Intel Pentium III Xeon processors which could be used with up to four processors in a system natively.

During the Katmai project Intel sought to distinguish it from their earlier product line, particularly their flagship Pentium II.

For example, some low-end workstations use CISC based processors like the Intel Core or AMD Phenom II or FX as their CPUs.

Initially, bus implementations were proprietary ( such as the Apple II and Macintosh ), but by the late 1970s manufacturers of Intel 8080 / Zilog Z80-based computers running CP / M had settled around the S-100 standard.

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.

After the microprocessor was released, a bug was discovered in the floating point unit, commonly called the " Pentium Pro and Pentium II FPU bug " and by Intel as the " flag erratum ".

The Intel 440FX chipset explicitly supported both Pentium Pro and Pentium II processors, but the Intel 440BX and later Slot 1 chipsets did not explicitly support the Pentium Pro, so the Socket 8 slockets did not see wide use.

* List of Intel Pentium II microprocessors

As noted in the Pentium II Processor update documentation from Intel, " Please note that although this processor has a CPUID of 163xh, it uses a Pentium II processor CPUID 065xh processor core.

The term came into use by Intel Corporation about the time the Pentium Pro and Pentium II products were announced, in the 1990s.

x86 assembly language is a family of backward-compatible assembly languages, which provide some level of compatibility all the way back to the Intel 8008. x86 assembly languages are used to produce object code for the x86 class of processors, which includes Intel's Core series and AMD's Phenom and Phenom II series.

Intel used a package designated BGA1 for their Pentium II and early Celeron mobile processors.

Another high profile Quadrics system was the fastest Linux cluster in the world called Thunder installed at Lawrence Livermore National Laboratory in 2003 / 2004, Thunder consisted of 1024 Intel Tiger Quad Itanium II Processor servers to deliver 19. 94 teraflops on parallel Linpack.

For an extremely short time after its release, the fastest available desktop processor from Intel was the Pentium II 450 MHz.
