Clarkdale (microprocessor)
Clarkdale is the codename for Intel's first-generation Core i5, i3 and Pentium dual-core desktop processors. It is closely related to the mobile Arrandale processor; both use dual-core dies based on the 32 nm Westmere microarchitecture and have integrated Graphics, PCI Express and DMI links built-in. Clarkdale is the successor of the Wolfdale used in desktop Intel Core 2, Celeron and Pentium Dual-Core processors. Unlike its predecessor, Clarkdale already contains the major north bridge components, such as memory controller, PCI Express for external graphics, integrated graphics and the DMI connector, making it possible to build more compact systems without a separate north bridge or discrete graphics like Lynnfield. The Clarkdale processor package contains two dies: the 32 nm processor die with the I/O connections, and the 45 nm graphics and integrated memory controller die. Physical separation of the processor die and memory controller die resulted in increased m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
32 Nm
The 32 nm node is the step following the 45 nm process in CMOS (MOSFET) semiconductor device fabrication. "32-nanometre" refers to the average half-pitch (i.e., half the distance between identical features) of a memory cell (computing), memory cell at this technology level. Toshiba produced commercial 32Gibibit, GiB NAND flash memory chips with the 32nm process in 2009. Intel Corporation, Intel and Advanced Micro Devices, AMD produced commercial microchips using the 32-nanometre process in the early 2010s. IBM and the Common Platform also developed a 32 nm high-κ dielectric, high-κ metal gate process. Intel began selling its first 32 nm processors using the Westmere (microarchitecture), Westmere architecture on 7 January 2010. The 28-nanometre node was an intermediate half-node die shrink based on the 32-nanometre process. The 32 nm process was superseded by commercial 22 nm process, 22 nm technology in 2012.

Arrandale (microprocessor)
Arrandale is the code name for a family of mobile Intel processors, sold as mobile Intel Core i3, i5 and i7 as well as Celeron and Pentium. It is closely related to the desktop Clarkdale processor; both use dual-core dies based on the '' Westmere'' 32 nm die shrink of the Nehalem microarchitecture, and have integrated Graphics as well as PCI Express and DMI links. Arrandale is the successor of the 45 nm Core-microarchitecture-based Penryn processor that is used in many of the mobile Intel Core 2, Celeron and Pentium Dual-Core processors. While Penryn typically used both a north bridge and a south bridge, Arrandale already contains the major northbridge components, which are the memory controller, PCI Express bus for external graphics, integrated graphics, and the DMI interface, making it possible to build more compact systems. The Arrandale processor package contains two dies: the 32 nm processor die with the I/O connections, and the 45 nm Intel HD Grap ...

Simultaneous Multithreading
Simultaneous multithreading (SMT) is a technique for improving the overall efficiency of superscalar CPUs with hardware multithreading. SMT permits multiple independent threads of execution to better use the resources provided by modern processor architectures. Details The term ''multithreading'' is ambiguous, because not only can multiple threads be executed simultaneously on one CPU core, but also multiple tasks (with different page tables, different task state segments, different protection rings, different I/O permissions, etc.). Although running on the same core, they are completely separated from each other. Multithreading is similar in concept to preemptive multitasking but is implemented at the thread level of execution in modern superscalar processors. Simultaneous multithreading (SMT) is one of the two main implementations of multithreading, the other form being temporal multithreading (also known as super-threading). In temporal multithreading, only one thread of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intel Turbo Boost
Intel Turbo Boost is Intel's trade name for central processing units (CPUs) dynamic frequency scaling feature that automatically raises certain versions of its operating frequency when demanding tasks are running, thus enabling a higher resulting performance. The frequency is accelerated when the operating system requests the highest performance state of the processor. Processor performance states are defined by the Advanced Configuration and Power Interface (ACPI) specification, an open standard supported by all major operating systems; no additional software or drivers are required to support the technology. The design concept behind Turbo Boost is commonly referred to as "dynamic overclocking". When the workload on the processor calls for faster performance, the processor's clock will try to increase the operating frequency in regular increments as required to meet demand. The increased clock rate is limited by the processor's power, current, and thermal limits, the number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trusted Execution Technology
Intel Trusted Execution Technology (Intel TXT, formerly known as LaGrande Technology) is a computer hardware technology whose primary goals are: * Attestation of the authenticity of a platform and its operating system. * Assuring that an authentic operating system starts in a trusted environment, which can then be considered trusted. * Provision of a trusted operating system with additional security capabilities not available to an unproven one. Intel TXT uses a Trusted Platform Module (TPM) and cryptographic techniques to provide measurements of software and platform components so that system software as well as local and remote management applications may use those measurements to make trust decisions. It complements Intel Management Engine. This technology is based on an industry initiative by the Trusted Computing Group (TCG) to promote safer computing. It defends against software-based attacks aimed at stealing sensitive information by corrupting system or BIOS code, or mod ...

Intel VT-d
x86 virtualization is the use of hardware-assisted virtualization capabilities on an x86/x86-64 CPU. In the late 1990s x86 virtualization was achieved by complex software techniques, necessary to compensate for the processor's lack of hardware-assisted virtualization capabilities while attaining reasonable performance. In 2005 and 2006, both Intel (VT-x) and AMD ( AMD-V) introduced limited hardware virtualization support that allowed simpler virtualization software but offered very few speed benefits. Greater hardware support, which allowed substantial speed improvements, came with later processor models. Software-based virtualization The following discussion focuses only on virtualization of the x86 architecture protected mode. In protected mode the operating system kernel runs at a higher privilege such as ring 0, and applications at a lower privilege such as ring 3. In software-based virtualization, a host OS has direct access to hardware while the guest OSs have limited ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intel Core
Intel Core is a line of streamlined midrange consumer, workstation and enthusiast computer central processing units (CPUs) 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. The lineup of Core processors includes the Intel Core i3, Intel Core i5, Intel Core i7, and Intel Core i9, along with the X-series of Intel Core CPUs. Outline Although Intel Core is a brand that promises no internal consistency or continuity, the processors within this family have been, for the most part, broadly similar. The first products receiving this designation were the Core Solo and Core Duo Yonah processors for mobile from the Pentium M design tree, fabricated at 65 nm and brought to market in January 2006. These are substantially diffe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CPUID
In the x86 architecture, the CPUID instruction (identified by a CPUID opcode) is a processor supplementary instruction (its name derived from CPU IDentification) allowing software to discover details of the processor. It was introduced by Intel in 1993 with the launch of the Pentium and SL-enhanced 486 processors. A program can use the CPUID to determine processor type and whether features such as MMX/ SSE are implemented. History Prior to the general availability of the CPUID instruction, programmers would write esoteric machine code which exploited minor differences in CPU behavior in order to determine the processor make and model. With the introduction of the 80386 processor, EDX on reset indicated the revision but this was only readable after reset and there was no standard way for applications to read the value. Outside the x86 family, developers are mostly still required to use esoteric processes (involving instruction timing or CPU fault triggers) to determine the var ...

Lynnfield (microprocessor)
Lynnfield is the code name for a quad-core processor from Intel released in September 2009. It was sold in varying configurations as Core i5-7xx, Core i7-8xx or Xeon X34xx. Lynnfield uses the Nehalem microarchitecture and replaces the earlier Penryn based Yorkfield processor, using the same 45 nm process technology, but with a new memory and bus interface. The product code for Lynnfield is 80605, its CPUID value identifies it as family 6, model 30 (0106Ex). Lynnfield is related to the earlier Bloomfield and Gainestown microprocessors, which are used in server and high-end desktop systems. The main difference between the two is Lynnfield's use of the LGA 1156 processor socket as opposed to the LGA 1366 socket used by Bloomfield and Gainestown processors. LGA 1156 processors include Direct Media Interface and PCI Express links, which Intel has previously connected to the processor with a dedicated northbridge chip, called the ''memory controller hub'' or ''I/O hub''. The Lynnf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northbridge (computing)
In computing, a northbridge (also host bridge, or memory controller hub) is one of two chips comprising the core logic chipset architecture on a PC motherboard. A northbridge is connected directly to a CPU via the front-side bus (FSB) to handle high-performance tasks, and is usually used in conjunction with a slower southbridge to manage communication between the CPU and other parts of the motherboard. Since the 2010s, die shrink and improved transistor density have allowed for increasing chipset integration, and the functions performed by northbridges are now often incorporated into other components (like southbridges or CPUs themselves). As of 2019, Intel and AMD had both released chipsets in which all northbridge functions had been integrated into the CPU. Modern Intel Core processors have the northbridge integrated on the CPU die, where it is known as the uncore or system agent. On older Intel based PCs, the northbridge was also named external memory controller hub ('' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pentium Dual-Core
The Pentium Dual-Core brand was used for mainstream x86-architecture microprocessors from Intel from 2006 to 2009 when it was renamed to Pentium. The processors are based on either the 32-bit '' Yonah'' or (with quite different microarchitectures) 64-bit '' Merom-2M'', '' Allendale'', and '' Wolfdale-3M'' core, targeted at mobile or desktop computers. In terms of features, price, and performance at a given clock frequency, Pentium Dual-Core processors were positioned above Celeron but below Core and Core 2 processors in Intel's product range. The Pentium Dual-Core was also a very popular choice for overclocking, as it can deliver high performance (when overclocked) at a low price. Processor cores In 2006, Intel announced a plan to return the Pentium trademark from retirement to the market, as a moniker of low-cost Core microarchitecture processors based on the single-core Conroe-L but with 1 MB of cache. The identification numbers for those planned Pentiums were similar to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intel Core 2
Intel Core 2 is the processor family encompassing a range of Intel's consumer 64-bit x86-64 single-, dual-, and quad-core microprocessors based on the Core microarchitecture. The single- and dual-core models are single-die, whereas the quad-core models comprise two dies, each containing two cores, packaged in a multi-chip module. The Core 2 range was the last flagship range of Intel desktop processors to use a front-side bus. The introduction of Core 2 relegated the Pentium brand to the mid-range market, and reunified laptop and desktop CPU lines for marketing purposes under the same product name, which were formerly divided into the Pentium 4, Pentium D, and Pentium M brands. The ''Core 2'' processor line was introduced on July 27, 2006, comprising the ''Duo'' (dual-core) and ''Extreme'' (dual- or quad-core CPUs for enthusiasts), and in 2007, the ''Quad'' (quad-core) and ''Solo'' (single-core) sub-brands.
