Nehalem (microarchitecture)
Nehalem is the codename for Intel's 45 nm microarchitecture released in November 2008. It was used in the first generation of the Intel Core i5 and i7 processors, and succeeds the older Core microarchitecture used on Core 2 processors. The term "Nehalem" comes from the Nehalem River. Nehalem is built on the 45 nm process, is able to run at higher clock speeds without sacrificing efficiency, and is more energy-efficient than Penryn microprocessors. Hyper-threading is reintroduced, along with a reduction in L2 cache size, as well as an enlarged L3 cache that is shared among all cores. Nehalem is an architecture that differs radically from NetBurst, while retaining some of the latter's minor features. Nehalem later received a die-shrink to 32 nm with Westmere, and was fully succeeded by "second-generation" Sandy Bridge in January 2011. Technology * Cache line block on L2/L3 cache was reduced from 128 bytes in NetBurst & Merom/Penryn to 64 bytes per line in this gene ...

45 Nm Process
Per the International Technology Roadmap for Semiconductors, the 45 nm process is a MOSFET technology node referring to the average half-pitch of a memory cell manufactured at around the 2007–2008 time frame. Matsushita and Intel started mass-producing 45 nm chips in late 2007, and AMD started production of 45 nm chips in late 2008, while IBM, Infineon, Samsung, and Chartered Semiconductor have already completed a common 45 nm process platform. At the end of 2008, SMIC was the first China-based semiconductor company to move to 45 nm, having licensed the bulk 45 nm process from IBM. In 2008, TSMC moved on to a 40nm process. Many critical feature sizes are smaller than the wavelength of light used for lithography (i.e., 193 nm and 248 nm). A variety of techniques, such as larger lenses, are used to make sub-wavelength features. Double patterning has also been introduced to assist in shrinking distances between features, especially if dry lit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penryn (microarchitecture)
In Intel's Tick-Tock cycle, the 2007/2008 "Tick" was the shrink of the Core microarchitecture to 45 nanometers as CPUID model 23. In Core 2 processors, it is used with the code names Penryn (Socket P), Wolfdale (LGA 775) and Yorkfield (MCM, LGA 775), some of which are also sold as Celeron, Pentium and Xeon processors. In the Xeon brand, the Wolfdale-DP and Harpertown code names are used for LGA 771 based MCMs with two or four active Wolfdale cores. Architectural improvements over 65-nanometer Core 2 CPUs include a new divider with reduced latency, a new shuffle engine, and SSE4.1 instructions (some of which are enabled by the new single-cycle shuffle engine). Maximum L2 cache size per chip was increased from 4 to 6 MB, with L2 associativity increased from 16-way to 24-way. Cut-down versions with 3 MB L2 also exist, which are commonly called Penryn-3M and Wolfdale-3M as well as Yorkfield-6M, respectively. The single-core version of Penryn, listed as Penryn-L here, is not a sepa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intel Core (microarchitecture)
The Intel Core microarchitecture (provisionally referred to as Next Generation Micro-architecture, and developed as Merom) is a multi-core processor microarchitecture launched by Intel in mid-2006. It is a major evolution over the Yonah, the previous iteration of the P6 microarchitecture series which started in 1995 with Pentium Pro. It also replaced the NetBurst microarchitecture, which suffered from high power consumption and heat intensity due to an inefficient pipeline designed for high clock rate. In early 2004, Prescott needed very high power to reach the clocks it needed for competitive performance, making it unsuitable for the shift to dual/multi-core CPUs. On May 7, 2004, Intel confirmed the cancellation of the next NetBurst, Tejas and Jayhawk. Intel had been developing Merom, the 64-bit evolution of the Pentium M, since 2001, and decided to expand it to all market segments, replacing NetBurst in desktop computers and servers. It inherited from Pentium M the choi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
65 Nm Process
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 the ...

90 Nm Process
The 90 nm process refers to the technology used in semiconductor manufacturing to create integrated circuits with a minimum feature size of 90 nanometers. It was an advancement over the previous 130 nm process. Eventually, it was succeeded by smaller process nodes, such as the 65 nm, 45 nm, and 32 nm processes. It was commercialized by the 2003–2005 timeframe, by semiconductor companies including Toshiba, Sony, Samsung, IBM, Intel, Fujitsu, TSMC, Elpida, AMD, Infineon, Texas Instruments and Micron Technology. The origin of the 90 nm value is historical; it reflects a trend of 70% scaling every 2–3 years. The naming is formally determined by the International Technology Roadmap for Semiconductors (ITRS). The 300 mm wafer size became mainstream at the 90 nm node. The previous wafer size was 200 mm diameter. The 193 nm wavelength was introduced by many (but not all) companies for lithography of critical layers mainly during the 90 nm nod ...

Enhanced Pentium M (microarchitecture)
The P6 microarchitecture is the sixth-generation Intel x86 microarchitecture, implemented by the Pentium Pro microprocessor that was introduced in November 1995. It is frequently referred to as i686. It was planned to be succeeded by the NetBurst microarchitecture used by the Pentium 4 in 2000, but was revived for the Pentium M line of microprocessors. The successor to the Pentium M variant of the P6 microarchitecture is the Core microarchitecture which in turn is also derived from P6. P6 was used within Intel's mainstream offerings from the Pentium Pro to Pentium III, and was widely known for low power consumption, excellent integer performance, and relatively high instructions per cycle (IPC). The P6 core was the sixth generation Intel microprocessor in the x86 line. The first implementation of the P6 core was the Pentium Pro CPU in 1995, the immediate successor to the original Pentium design (P5). P6 processors dynamically translate IA-32 instructions into sequences of bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NetBurst
The NetBurst microarchitecture, called P68 inside Intel, was the successor to the P6 microarchitecture in the x86 family of central processing units (CPUs) made by Intel. The first CPU to use this architecture was the Willamette-core Pentium 4, released on November 20, 2000 and the first of the Pentium 4 CPUs; all subsequent Pentium 4 and Pentium D variants have also been based on NetBurst. In mid-2001, Intel released the ''Foster'' core, which was also based on NetBurst, thus switching the Xeon CPUs to the new architecture as well. Pentium 4-based Celeron CPUs also use the NetBurst architecture. NetBurst was replaced with the Core microarchitecture based on P6, released in July 2006. Technology The NetBurst microarchitecture includes features such as Hyper-threading, Hyper Pipelined Technology, Rapid Execution Engine, Execution Trace Cache, and replay system which all were introduced for the first time in this particular microarchitecture, and some never appeared ...

130 Nm Process
The 130 nanometer (130 nm) process is a level of semiconductor process technology that was reached in the 2000–2001 timeframe by such leading semiconductor companies as Intel, Texas Instruments, IBM, and TSMC. The origin of the 130 nm value is historical, as it reflects a trend of 70% scaling every 2–3 years. The naming is formally determined by the International Technology Roadmap for Semiconductors (ITRS). Some of the first CPUs manufactured with this process include Intel Tualatin family of Pentium III processors. Processors using 130 nm manufacturing technology * Motorola PowerPC 7447 and 7457 2002 * IBM Gekko (GameCube) * IBM PowerPC G5 970 - October 2002 - June 2003 * Intel Pentium III Tualatin - 2001-06 * Intel Celeron Tualatin-256 - 2001-10-02 * Intel Pentium M Banias - 2003-03-12 * Intel Pentium 4 Northwood - 2002-01-07 * Intel Celeron Northwood-128 - 2002-09-18 * Intel Xeon Prestonia and Gallatin - 2002-02-25 * VIA C3 - 2001 * AMD Athlon XP Thoroughbred, ...
