Please answer the following question: Information:  - IA-32 (short for "Intel Architecture, 32-bit", sometimes also called i386) is the 32-bit version of the x86 instruction set architecture (ISA), first implemented in the Intel 80386 microprocessors in 1985. IA-32 is the first incarnation of x86 that supports 32-bit computing; as a result, the "IA-32" term may be used as a metonym to refer to all x86 versions that support 32-bit computing.  - Opteron is AMD's x86 server and workstation processor line, and was the first processor which supported the AMD64 instruction set architecture (known generically as x86-64). It was released on April 22, 2003 with the "SledgeHammer" core (K8) and was intended to compete in the server and workstation markets, particularly in the same segment as the Intel Xeon processor. Processors based on the AMD K10 microarchitecture (codenamed "Barcelona") were announced on September 10, 2007 featuring a new quad-core configuration. The most-recently released Opteron CPUs are the Piledriver-based Opteron 4300 and 6300 series processors, codenamed "Seoul" and "Abu Dhabi" respectively. In January 2016, the first ARMv8-A based Opteron SoC was released.  - Athlon is the brand name applied to a series of x86-compatible microprocessors designed and manufactured by Advanced Micro Devices (AMD). The original Athlon (now called "Athlon Classic") was the first seventh-generation x86 processor. The original Athlon was the first desktop processor to reach speeds of one gigahertz (GHz). AMD has continued using the "Athlon" name with the Athlon 64, an eighth-generation processor featuring x86-64 (later renamed AMD64) architecture, and the Athlon II. AMD also uses the "Athlon" name for some of its series of APUs targeting the Socket AM1 desktop SoC architecture.  - The Athlon 64 X2 is the first dual - core desktop CPU designed by AMD . It was designed from scratch as native dual - core by using an already multi-CPU enabled Athlon 64 , joining it with another functional core on one die , and connecting both via a shared dual - channel memory controller / north bridge and additional control logic . The initial versions are based on the E-stepping model of the Athlon 64 and , depending on the model , have either 512 or 1024 KB of L2 Cache per core . The Athlon 64 X2 is capable of decoding SSE3 instructions ( except those few specific to Intel 's architecture ) . In June 2007 , AMD released low - voltage variants of their low - end 65 nm Athlon 64 X2 , named `` Athlon X2 '' . The Athlon X2 processors feature reduced TDP of 45 W. The name was also used for K10 based budget CPUs with two cores deactivated .  - Pentium is a brand used for a series of x86-compatible microprocessors produced by Intel since 1993. In its current form, Pentium processors are considered entry-level products that Intel rates as "two stars", meaning that they are above the low-end Atom and Celeron series but below the faster Core i3, i5 and i7 lines as well as the high-end Xeon processors.  - x86 is a family of backward compatible instruction set architectures based on the Intel 8086 CPU and its Intel 8088 variant. The 8086 was introduced in 1978 as a fully 16-bit extension of Intel's 8-bit based 8080 microprocessor, with memory segmentation as a solution for addressing more memory than can be covered by a plain 16-bit address. The term "x86" came into being because the names of several successors to Intel's 8086 processor end in "86", including the 80186, 80286, 80386 and 80486 processors.  - Intel Corporation (also known as Intel, stylized as intel) is an American multinational corporation and technology company headquartered in Santa Clara, California (colloquially referred to as "Silicon Valley") that was founded by Gordon Moore (of Moore's law fame) and Robert Noyce. It is the world's largest and highest valued semiconductor chip makers based on revenue, and is the inventor of the x86 series of microprocessors: the processors found in most personal computers (PCs). Intel supplies processors for computer system manufacturers such as Apple, Lenovo (formerly IBM), HP, and Dell. Intel also manufactures motherboard chipsets, network interface controllers and integrated circuits, flash memory, graphics chips, embedded processors and other devices related to communications and computing.  - 3DNow! is an extension to the x86 instruction set developed by Advanced Micro Devices (AMD). It adds single instruction multiple data (SIMD) instructions to the base x86 instruction set, enabling it to perform vector processing, which improves the performance of many graphic-intensive applications. The first microprocessor to implement 3DNow was the AMD K6-2, which was introduced in 1998. When the application was appropriate this raised the speed by about 2-4 times.  - Pentium 4 was a line of single-core central processing units (CPUs) for desktops, laptops and entry-level servers introduced by Intel on November 20, 2000 and shipped through August 8, 2008. They had a seventh-generation x86 (32-bit) microarchitecture, called NetBurst, which was the company's first all-new design since the introduction of the P6 microarchitecture of the Pentium Pro CPUs in 1995. NetBurst differed from P6 (Pentium III, II, etc.) by featuring a very deep instruction pipeline to achieve very high clock speeds. Intel claimed that NetBurst would allow clock speeds of up to 10 GHz in future chips; however, severe problems with heat dissipation (especially with the Prescott Pentium 4) limited CPU clock speeds to a much lower 3.8 GHz.  - The Athlon 64 is an eighth-generation, AMD64-architecture microprocessor produced by AMD, released on September 23, 2003. It is the third processor to bear the name "Athlon", and the immediate successor to the Athlon XP. The second processor (after the Opteron) to implement AMD64 architecture and the first 64-bit processor targeted at the average consumer, it was AMD's primary consumer microprocessor, and competes primarily with Intel's Pentium 4, especially the "Prescott" and "Cedar Mill" core revisions. It is AMD's first K8, eighth-generation processor core for desktop and mobile computers. Despite being natively 64-bit, the AMD64 architecture is backward-compatible with 32-bit x86 instructions. Athlon 64s have been produced for Socket 754, Socket 939, Socket 940 and Socket AM2. The line was succeeded by the dual-core Athlon 64 X2 and Athlon X2 lines.  - SSE3, Streaming SIMD Extensions 3, also known by its Intel code name Prescott New Instructions (PNI), is the third iteration of the SSE instruction set for the IA-32 (x86) architecture. Intel introduced SSE3 in early 2004 with the Prescott revision of their Pentium 4 CPU. In April 2005, AMD introduced a subset of SSE3 in revision E (Venice and San Diego) of their Athlon 64 CPUs. The earlier SIMD instruction sets on the x86 platform, from oldest to newest, are MMX, 3DNow! (developed by AMD), SSE and SSE2.  - SSE2 (Streaming SIMD Extensions 2), is one of the Intel SIMD (Single Instruction, Multiple Data) processor supplementary instruction sets first introduced by Intel with the initial version of the Pentium 4 in 2001. It extends the earlier SSE instruction set, and is intended to fully replace MMX. Intel extended SSE2 to create SSE3 in 2004. SSE2 added 144 new instructions to SSE, which has 70 instructions. Competing chip-maker AMD added support for SSE2 with the introduction of their Opteron and Athlon 64 ranges of AMD64 64-bit CPUs in 2003.
