Yonah (microprocessor)
Yonah is the code name of Intel's first generation 65 nm process CPU cores, based on cores of the earlier Banias (130 nm) / Dothan (90 nm) Pentium M microarchitecture. Yonah CPU cores were used within Intel's Core Solo and Core Duo mobile microprocessor products. SIMD performance on Yonah improved through the addition of SSE3 instructions and improvements to SSE and SSE2 implementations; integer performance decreased slightly due to higher latency cache. Additionally, Yonah included support for the NX bit. Models and brand names The Intel Core Duo brand referred to a low-power (less than 25 watts) dual-core microprocessor, which offered lower power operation than the competing AMD Opteron 260 and 860 HE at 55 watts. Core Duo was released on January 5, 2006, with the other components of the Napa platform. It was the first Intel processor to be used in Apple Macintosh products (although the Apple Developer Transition Kit machines, non-production units ...

65 Nm
The 65 nm process is an advanced lithographic node used in volume CMOS (MOSFET) semiconductor fabrication. Printed linewidths (i.e. transistor gate lengths) can reach as low as 25 nm on a nominally 65 nm process, while the pitch between two lines may be greater than 130 nm. Process node For comparison, cellular ribosomes are about 20 nm end-to-end. A crystal of bulk silicon has a lattice constant of 0.543 nm, so such transistors are on the order of 100 atoms across. By September 2007, Intel, AMD, IBM, UMC and Chartered were also producing 65 nm chips. While feature sizes may be drawn as 65 nm or less, the wavelengths of light used for lithography are 193 nm and 248 nm. Fabrication of sub-wavelength features requires special imaging technologies, such as optical proximity correction and phase-shifting masks. The cost of these techniques adds substantially to the cost of manufacturing sub-wavelength semiconductor products, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Core Duo
Intel Core is a line of multi-core (with the exception of Core Solo and Core 2 Solo) central processing units (CPUs) for midrange, embedded, workstation, high-end and enthusiast computer markets marketed by Intel Corporation. These processors displaced the existing mid- to high-end Pentium processors at the time of their introduction, moving the Pentium to the entry level. Identical or more capable versions of Core processors are also sold as Xeon processors for the server and workstation markets. Core was launched in January 2006 as a mobile-only series, consisting of single- and dual-core models. It was then succeeded later in July by the Core 2 series, which included both desktop and mobile processors with up to four cores, and introduced 64-bit support. Since 2008, Intel began introducing the Core i3, Core i5, Core i7 and Core i9 lineup of processors, succeeding Core 2. A new naming scheme debuted in 2023, consisting of Core 3, Core 5, and Core 7 for mainstream processo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physical Address Extension
In computing, Physical Address Extension (PAE), sometimes referred to as Page Address Extension, is a memory management feature for the x86 architecture. PAE was first introduced by Intel in the Pentium Pro, and later by AMD in the Athlon processor. It defines a page table hierarchy of three levels (instead of two), with table entries of 64 bits each instead of 32, allowing these CPUs to directly access a physical address space larger than 4 gigabytes (232 bytes). The page table structure used by x86-64 CPUs when operating in long mode further extends the page table hierarchy to four or more levels, extending the virtual address space, and uses additional physical address bits at all levels of the page table, extending the physical address space. It also uses the topmost bit of the 64-bit page table entry as a no-execute or "NX" bit, indicating that code cannot be executed from the associated page. The NX feature is also available in protected mode when these CPUs are run ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AMD Quad FX
The AMD Quad FX platform is an AMD platform targeted at enthusiasts which allows users to plug two Socket F Athlon 64 FX or 2-way Opteron processors (CPUs) into a single motherboard for a total of four physical cores. This is a type of dual processor setup, where two CPUs are installed on a motherboard to increase computing power. The major difference between the platform and past dual processor systems like Xeon (pre Intel 5000X/P chipset) is that each processor has its own dedicated memory stores. The Quad FX platform also has HyperTransport capability targeted toward consumer platforms. In May 2007, AMD officially codenamed the eight core setup with two Phenom FX processors to be the ''FASN8'' (pronounced as "fascinate", , in short for ''First AMD Silicon Next-gen 8-core Platform'') from the previous codename "''4x4+''" used in Analyst Day presentations. Configuration In each socket resides an AMD Athlon 64 FX CPU. Each socket is connected using AMD's Direct Chip Module, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xeon
Xeon (; ) is a brand of x86 microprocessors designed, manufactured, and marketed by Intel, targeted at the non-consumer workstation, server, and embedded markets. It was introduced in June 1998. Xeon processors are based on the same architecture as regular desktop-grade CPUs, but have advanced features such as support for error correction code (ECC) memory, higher core counts, more PCI Express lanes, support for larger amounts of RAM, larger cache memory and extra provision for enterprise-grade reliability, availability and serviceability (RAS) features responsible for handling hardware exceptions through the Machine Check Architecture (MCA). They are often capable of safely continuing execution where a normal processor cannot due to these extra RAS features, depending on the type and severity of the machine-check exception (MCE). Some also support multi-socket systems with two, four, or eight sockets through use of the Ultra Path Interconnect (UPI) bus, which replaced ...

Pentium 4
Pentium 4 is a series of single-core central processing unit, CPUs for Desktop computer, desktops, laptops and entry-level Server (computing), servers manufactured by Intel. The processors were shipped from November 20, 2000 until August 8, 2008. All Pentium 4 CPUs are based on the NetBurst microarchitecture, the successor to the P6 (microarchitecture), P6. The Pentium 4 #Willamette, Willamette (180 nm) introduced SSE2, while the #Prescott, Prescott (90 nm) introduced SSE3 and later 64-bit technology. Later versions introduced Hyper-threading, Hyper-Threading Technology (HTT). The first Pentium 4-branded processor to implement x86-64, 64-bit was the Prescott (90 nm) (February 2004), but this feature was not enabled. Intel subsequently began selling 64-bit Pentium 4s using the ''"E0" revision'' of the Prescotts, being sold on the OEM market as the Pentium 4, model F. The E0 revision also adds eXecute Disable (XD) (Intel's name for the NX bit) to Intel 64. Int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apple Macintosh
Mac is a brand of personal computers designed and marketed by Apple Inc., Apple since 1984. The name is short for Macintosh (its official name until 1999), a reference to the McIntosh (apple), McIntosh apple. The current product lineup includes the MacBook Air and MacBook Pro laptops, and the iMac, Mac Mini, Mac Studio, and Mac Pro desktops. Macs are currently sold with Apple's UNIX-based macOS operating system, which is Proprietary software, not licensed to other manufacturers and exclusively Pre-installed software, bundled with Mac computers.

Mac Transition To Intel Processors
The Mac transition to Intel processors was the process of switching the central processing units (CPUs) of Apple's line of Mac and Xserve computers from PowerPC processors over to Intel's x86-64 processors. The change was announced at the 2005 Worldwide Developers Conference (WWDC) by then-Apple CEO Steve Jobs, who said Apple would gradually stop using PowerPC microprocessors supplied by Freescale (formerly Motorola) and IBM. The transition was the second time Apple had switched the processor instruction set architecture of its personal computers. The first was in 1994, when Apple discarded the Mac's original Motorola 68000 series architecture in favor of the then-new PowerPC platform. Apple's initial press release originally outlined that the move would begin by June 2006, with completion slated by early 2008 – the transition had proceeded faster than anticipated. The first-generation Intel-based Macs were released in January 2006 with Mac OS X 10.4.4 Tiger. In August, Jo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centrino
Centrino was a brand name of Intel Corporation which represented its Wi-Fi and WiMAX wireless computer networking adapters. The brand name was first used by the company as a platform-marketing initiative. The change of the meaning of the brand name occurred on January 7, 2010. The Centrino name for laptops was replaced by the Ultrabook. The old platform-marketing brand name covered a particular combination of mainboard chipset, mobile CPU and wireless network interface in the design of a laptop. Intel claimed that systems equipped with these technologies delivered better performance, longer battery life and broader wireless network interoperability than non-Centrino systems. The product line name for Intel wireless products became Intel Centrino Wireless in 2010. The Centrino brand was ultimately discontinued in 2013. Intel Centrino Notebook implementations Carmel platform (2003) Intel used " Carmel" as the codename for the first-generation Centrino platform, introduced ...

Dual-core
A multi-core processor (MCP) is a microprocessor on a single integrated circuit (IC) with two or more separate central processing units (CPUs), called ''cores'' to emphasize their multiplicity (for example, ''dual-core'' or ''quad-core''). Each core reads and executes Instruction set, program instructions, specifically ordinary Instruction set, CPU instructions (such as add, move data, and branch). However, the MCP can run instructions on separate cores at the same time, increasing overall speed for programs that support Multithreading (computer architecture), multithreading or other parallel computing techniques. Manufacturers typically integrate the cores onto a single IC Die (integrated circuit), die, known as a ''chip multiprocessor'' (CMP), or onto multiple dies in a single Chip carrier, chip package. As of 2024, the microprocessors used in almost all new personal computers are multi-core. A multi-core processor implements multiprocessing in a single physical package. Des ...
