Pentium Overdrive
The Pentium OverDrive was a microprocessor marketing brand name used by Intel, to cover a variety of consumer upgrade products sold in the mid-1990s. It was originally released for Intel 80486, 486 motherboards, and later some Pentium compatible processor, Pentium sockets. Intel dropped the brand, as it failed to appeal to corporate buyers, and discouraged new system sales. 486 sockets The Pentium OverDrive is a heavily modified, 3.3 volt Pentium P54 core manufactured on 600 nm process, 0.6 micrometer technology. It is fitted with a 486-compatible Bus (computing), bus unit (though with an increased pin-count), an integrated Heat sink, heatsink and fan, and 32 kB of CPU cache, level 1 cache, double the 16 kB offered on regular P54C chips. As the data bus was effectively reduced to 32-bit width, per-clock performance was much lower than that of a 'regular' Pentium, though still substantially faster compared to a similarly clocked 486 owing to the Pentium's architectural improvements ...

Packard Bell
Packard Bell is a personal computer hardware brand which originated as Packard Bell Electronics, Inc., an independent American computer company. Packard Bell Electronics was founded in Los Angeles in 1986 by Israeli-American investors who bought the trademark rights to the historic Packard Bell Corporation from Teledyne; in spite of similarities in their names, Packard Bell has no connection to either Hewlett-Packard or Bell System. Packard Bell helped to pioneer the mass market for PCs in the United States by selling in big office stores. In the early 1990s, the company entered the European market and opened its regional headquarters in Wijchen, Netherlands, in 1993. By this time, they had become the second largest original equipment manufacturer (OEM) for IBM PC–compatibles in the U.S. Packard Bell merged its operations with Japanese electronics conglomerate NEC, known as Packard Bell NEC, in 1996; NEC took majority control in 1998 and made it a subsidiary.

MMX (instruction Set)
MMX is a ''single instruction, multiple data'' (SIMD) instruction set architecture designed by Intel, introduced on January 8, 1997 with its Pentium P5 (microarchitecture) based line of microprocessors, named "Pentium with MMX Technology". It developed out of a similar unit introduced on the Intel i860, and earlier the Intel i750 video pixel processor. MMX is a processor supplementary capability that is supported on IA-32 processors by Intel and other vendors . AMD also added MMX instruction set in its AMD K6, K6 processor. ''The New York Times'' described the initial push, including Super Bowl advertisements, as focused on "a new generation of glitzy multimedia products, including videophones and 3-D video games." MMX has subsequently been extended by several programs by Intel and others: 3DNow!, Streaming SIMD Extensions (SSE), and ongoing revisions of Advanced Vector Extensions (AVX).

Socket 5
Socket 5 was created for the second generation of Intel P5 (microarchitecture), P5 Pentium (brand), Pentium processors operating at speeds from 75 to 133 MHz as well as certain Pentium OverDrive and Pentium MMX processors with core voltage 3.3 V. It superseded the earlier Socket 4. It was released in March 1994. Consisting of 320 pins, this was the first socket to use a staggered pin grid array, or SPGA, which allowed the chip's pins to be spaced closer together than earlier sockets. Socket 5 was replaced by Socket 7 in 1995.

Socket 4
Socket 4, presented in 1993, was the first CPU socket designed for the early P5 Pentium microprocessors. Socket 4 was the only 5-volt socket for the Pentium. Socket 4 does support a special Pentium OverDrive, which allows running at 120 MHz (for the 60 MHz Pentium) or 133 MHz (for the 66 MHz Pentium). Socket 4 was superseded by the 3.3-volt-powered Socket 5 in 1994.

Front Side Bus
The front-side bus (FSB) is a computer communication interface (bus) that was often used in Intel-chip-based computers during the 1990s and 2000s. The EV6 bus served the same function for competing AMD CPUs. Both typically carry data between the central processing unit (CPU) and a memory controller hub, known as the northbridge. Depending on the implementation, some computers may also have a back-side bus that connects the CPU to the cache. This bus and the cache connected to it are faster than accessing the system memory (or RAM) via the front-side bus. The speed of the front side bus is often used as an important measure of the performance of a computer. The original front-side bus architecture was replaced by HyperTransport, Intel QuickPath Interconnect, and Direct Media Interface, followed by Intel Ultra Path Interconnect and AMD's Infinity Fabric. History The term came into use by Intel Corporation about the time the Pentium Pro and Pentium II products were announced, i ...

Megahertz
The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), often described as being equivalent to one event (or cycle) per second. The hertz is an SI derived unit whose formal expression in terms of SI base units is 1/s or s−1, meaning that one hertz is one per second or the reciprocal of one second. It is used only in the case of periodic events. It is named after Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves. For high frequencies, the unit is commonly expressed in multiples: kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz). Some of the unit's most common uses are in the description of periodic waveforms and musical tones, particularly those used in radio- and audio-related applications. It is also used to describe the clock speeds at which computers and other electronics are driven. The units are sometimes also used as a representation o ...

Windows
Windows is a Product lining, product line of Proprietary software, proprietary graphical user interface, graphical operating systems developed and marketed by Microsoft. It is grouped into families and subfamilies that cater to particular sectors of the computing industry – Windows (unqualified) for a consumer or corporate workstation, Windows Server for a Server (computing), server and Windows IoT for an embedded system. Windows is sold as either a consumer retail product or licensed to Original equipment manufacturer, third-party hardware manufacturers who sell products Software bundles, bundled with Windows. The first version of Windows, Windows 1.0, was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). The name "Windows" is a reference to the windowing system in GUIs. The 1990 release of Windows 3.0 catapulted its market success and led to various other product families ...

Emulator
In computing, an emulator is Computer hardware, hardware or software that enables one computer system (called the ''host'') to behave like another computer system (called the ''guest''). An emulator typically enables the host system to run software or use peripheral devices designed for the guest system. Emulation refers to the ability of a computer program in an electronic device to emulate (or imitate) another program or device. Many printer (computing), printers, for example, are designed to emulate Hewlett-Packard, HP LaserJet printers because a significant amount of software is written specifically for HP models. If a non-HP printer emulates an HP printer, any software designed for an actual HP printer will also function on the non-HP device, producing equivalent print results. Since at least the 1990s, many video game enthusiasts and hobbyists have used emulators to play classic arcade games from the 1980s using the games' original 1980s machine code and data, which is in ...

Peripheral Component Interconnect
Peripheral Component Interconnect (PCI) is a local computer bus for attaching hardware devices in a computer and is part of the PCI Local Bus standard. The PCI bus supports the functions found on a processor bus but in a standardized format that is independent of any given processor's native bus. Devices connected to the PCI bus appear to a bus master to be connected directly to its own bus and are assigned addresses in the processor's address space. It is a parallel bus, synchronous to a single bus clock. Attached devices can take either the form of an integrated circuit fitted onto the motherboard (called a ''planar device'' in the PCI specification) or an expansion card that fits into a slot. The PCI Local Bus was first implemented in IBM PC compatibles, where it displaced the combination of several slow Industry Standard Architecture (ISA) slots and one fast VESA Local Bus (VLB) slot as the bus configuration. It has subsequently been adopted for other computer types ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VESA Local Bus
The VESA Local Bus (usually abbreviated to VL-Bus or VLB) is a short-lived expansion bus introduced during the i486 generation of x86 IBM-compatible personal computers. Created by VESA (Video Electronics Standards Association), the VESA Local Bus worked alongside the then-dominant ISA bus to provide a standardized high-speed conduit intended primarily to accelerate video (graphics) operations. VLB provides a standardized fast path that add-in (video) card makers could tap for greatly accelerated memory-mapped I/O and DMA, while still using the familiar ISA bus to handle basic device duties such as interrupts and port-mapped I/O. Some high-end 386DX motherboards also had a VL-Bus slot. Historical overview In the early 1990s, the I/O bandwidth of the prevailing ISA bus, 8.33 MB/s for standard 16 bit 8.33 MHz slots, had become a critical bottleneck to PC video and graphics performance. The need for faster graphics was driven by increased adoption of graphical user interf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Socket 3
Socket 3 was a series of CPU sockets for various x86 microprocessors. It was sometimes found alongside a secondary socket designed for a math coprocessor chip, such as the 487. Socket 3 resulted from Intel's creation of lower voltage microprocessors. An upgrade to Socket 2, it rearranged the pin layout. Socket 3 is compatible with 168-pin socket CPUs. Socket 3 was a 237-pin zero insertion force (ZIF) 19×19 pin grid array (PGA) socket suitable for the 3.3 V and 5 V, 25–50 MHz Intel 486 SX, 486 DX, 486 DX2, 486 DX4, 486 OverDrive and Pentium OverDrive processors as well as AMD Am486, Am5x86 and Cyrix Cx5x86 processors.
