ADIng Technology (Hyper-Thre
ADIng Technology), packages with PPGA FC-PGA2, and PPGA. In
Accordance with
Intel's plans, Northwood core will soon be replaced by Prescott core. .
Prescott。.
This is the high-end Pentium 4 EE, mainstream low-end Pentium 4 and Celeron D used in the core. Northwood Prescott core and the core of the biggest difference is the adoption of 90nm process technology, L
1 data cache from 8KB to
16KB, pipelined from 20 to 3
1 level, and began to support the SSE3 instruction set. Prescott core CPU Socket 478 interface, the initial use, and now basically all go Socket 775 interface, the core voltage of
1. .25-
1. .525 V.。 L2 cache respectively 256KB (Celeron D),
1MB (Socket 478 pentium 4 interface, as well as Socket 775 Pentium 4 interface 5XX series) and 2 MB (Pentium 4 6xx sequence and Pentium 4 EE). PPGA package (Socket 478) and PLGA (Socket 775). . In
Accordance with
Intel's plans, Prescott core will be replaced by Cedar Mill core. .
Smithfield。.
This is
Intel's first dual-core processor core types, published in April 2005, is basically that the Smithfield core is a simple two loosely coupled with the Prescott core of the product, which is based on independent cache The loose coupling scheme, the advantage of simple technology, shortcomings in performance is not satisfactory. The current Pentium D 8XX series and the Pentium EE 8XX series with the core. Smithfield core using 90nm manufacturing process, all use Socket 775 interface, the core voltage of
1. .。 Front side bus frequency is 53
3MHz (Pentium D 8X5) and 800MHz (Pentium EE 8X0 and Pentium D 8XX), the frequency range from 3 to 2. .66GHz. .2GHz (Pentium D), 3. .2GHz (Pentium EE). Pentium EE and Pentium D, the
Maximum difference is Pentium EE support Hyper-Thre
ADIng technology and Pentium D is not supported. . In
Accordance with
Intel's plans, Smithfield core Presler core will soon be replaced. More information about Smithfield
Intel dual-core type to view. .
Cedar Mill。.
This is a Pentium 4 6X
1 series and Celeron D 3X2/3X6 family is the core, began to emerge from the end of 2005. The biggest difference with the Prescott core is the adoption of 65nm process technology, others are not changed much, basically that is the Prescott core, 65nm process version. Cedar Mill core all use Socket 775 interface, the core voltage of
1. .3 V or so packages using PLGA.。 Cedar Mill core
Intel processor is in the final NetBurst architecture on a single core processor core types,
According to
Intel, Cedar Mill core will gradually be Core Conroe core schema are replaced.
Presler. .
This is the Pentium D 9XX and Pentium EE core, 9XX adopts
Intel launched in late 2005. Basically you can think that the core Presler is a simple two Cedar Mill core loosely coupled together, the cache based on independent, loose coupling are the technical advantages, disadvantages are simple unsatisfactory performance. Core Presler 65nm manufacturing process used, the use of Socket 775 interface, the core voltage of
1. . Front side bus frequency is 800MHz (Pentium D) and
1066MHz (Pentium EE). With the Smithfield core similar, Pentium EE and Pentium D The biggest difference is that while Hyper-Thre
ADIng Technology Pentium EE Pentium D support is not supported, and the two cores each with 2MB of secondary cache.。 The core and the core Presler Smithfield, apart from adopting the 65nm process, each core L2 cache to 2MB and increased its virtualization technology support, technically there is little
INNOvation, basically can be thought of as the core of the 65nm process Smithfield.
Intel Presler core is also in the NetBurst architecture processor of dual-core processor-core type, can be said to be in the NetBurst abandoned before the final masterpiece, the
Intel desktop processors all transferred to the Core schema. . For more information on the Presler
Intel dual-core type to view. .
Yonah。.
Now adopted the core Yonah dual core CPU's are single-core Core Duo and Core Solo, Celeron M also has used this core, Yonah is
Intel launched in early 2006. This is a single / dual-core processor core types, its application is characterized by great flexibility, both for the desktop platform, but also for mobile platforms; can use dual-core, can also be used for single core.。 Yonah core uses 65nm manufacturing process, the core voltage
According to the version at the
1. .
1V-
1. .3V, package PPGA, interface type is the improved version of the Socket 478 interface (and previous desktop is not compatible with Socket 478 and). At FSB frequency, the Core Duo and Core Solo is 667MHz, Yonah core Celeron M is 53
3MHz. . Yonah core support hardware anti-virus technology and energy saving technology EDB EIST, and most models support the virtualization technology
Intel VT. But its biggest regret is that does not support 64-bit technology, just the 32-bit processors.。 This is strictly true dual-core Yonah core processors! is a shared cache of tight coupling scheme, its advantages are the
Ideal performance, the disadvantage is that technology is more complex. However, in
Accordance with the planning of future
Intel Intel processors each platform will be transferred to the Core schema, Yonah core is in fact just a
Transition of the core types, from the third quarter of 2006, its desktop platforms will be replaced, while the Conroe core on a mobile platform will be replaced by the Merom core.

Intel dual-core processor.
Intel introduced the present dual-core desktop processor Pentium D, Pentium EE (Pentium Extreme Edition) and Core Duo are three types of the three works are very different. .
First, the Pentium D and Pentium EE.
Pentium D and Pentium EE, respectively, and high-end market for the mainstream market, its stand-alone cache with each core design, the internal processor core between two mutually isolated by an external processor (motherboard north bridge chip) of the Arbitration is responsible for distribution of tasks between the two cores and the cache data synchronization coordination. Two cores share the front-side bus, and rely on front-side bus transfer between the two core data cache synchronization.。 In addition, Pentium D, Pentium EE
Maximum difference is Pentium EE support Hyper-Thre
ADIng technology and a Pentium D, Pentium EE is not supported in open the Hyper-Thre
ADIng technology then will be recognized by the
Operating system into four logical processors.
Pentium D and Pentium EE currently has the following produ
CTS:. .
Pentium D series: 8X0.
There are 820 (2. .8 GHz), 830 (3. .0 GHz) and 840 (3. .2 GHz) three produ
CTS are based on Smithfield core is actually two Pentium 4 Prescott processor core used in packaging together.。.
Pentium D 8X5 Series:. .

Intel VT and Pentium D 9
15 does not support save energy province electricity technology EIST, other technical characteristics and parameters are exactly the same.
It is note
WORTHY that,
Intel's Pentium D and Pentium EE processors with
AMD's dual-core Athlon 64 X2 (Data Base price reviews), and compared to Athlon 64 FX series are stand-alone secondary cache, in addition to the former co-ordination unit in the CPU external (depends on the motherboard), which in the internal CPU (not dependent on the motherboard), the essentially no significant difference, both relatively simple ---- just for the two cores can add a coordinating unit .。.
. .
According to
Intel's planning, from the third quarter of 2006,
Starting with the Pentium D and Pentium EE will gradually be based on the Core schema code dual-core processor Conroe..
2, Core Duo. .
With the Pentium D and Pentium EE based independent cache of loose coupling of dual-core processor is a completely different scenario is published at the beginning of 2006, the Core Duo-based shared cache of dual-core processor coupled programmes, their most important characteristics is the abandoned two core have independent two-pole cache scenarios, using IBM's multi-core processor is similar to one of the two core shared L2 cache. And independent secondary cache, shared L2 cache has the following advantages:.
1) 2 cache of all resources can be any one of the core visit, when the secondary cache data update, the two cores do not need to cache data synchronization work, the workload is relatively reduced, but also greatly reduces the cache data latency, which is conducive to enhance processor performance. .
2) before the two types of each core L2 cache resources are
Fixed, any one of the core can be based on the size of the workload to determine how many level 2 cache resource use efficiency relative to independent secondary cache has been greatly improved.
3) help reduce processor power consumption. Two cores can be divided into "cold core" and "thermonuclear" mode, the workload is large in the core are two full-speed
Operation, while the workload is small, you can make "cold core" di
Sabled, enter sleep mode, The continued
Operation of the "thermonuclear" can occupy all of the secondary cache of resources, compared to stand-alone cache on the left half of the secondary cache of resources available. .
Core Duo uses "Smart Cache" shared cache technology two core coordination between. . In addition, SBR also has the "Bandwidth Adaptation" (the bandwidth adaptation) capabilities, the two cores can share the front-side bus unified management and coordination of resources, improved front-side bus two cores sharing the efficiency and reduce un
NECessary delays, and effective avoid conflict between the two core. .
Smart Cache shared caching technology is proven dual-core processor with high performance solution, Smart Cache shared cache technology Core Duo also refle
CTS a strong performance, this is strictly true dual-core processor. Smart Cache shared caching techniques to be applied to all future
Intel dual-core processor, such as the upcoming Merom core
Notebook processors and Conroe core desktop processor using Smart Cache shared cache technology.
Although the share of secondary cache has a great advantage, but the technology than independent secondary cache much more complex, so individual processors in the X86 architecture
only the Core Duo is still
only used in the program. Core Duo in the current desktop is mainly used for T Series T2300 (
1. .66 GHz), T2400 (
1. .83 GHz), T2500 (2. .0 GHz) and T2600 (2..。 Current Desktop Core Duo combination of
Intel 945GT chipset is, of course, the original for
Notebook Intel 945GMS 945GM, 945PM, can also support Core Duo.
From the third quarter of 2006, desktop Core Duo will gradually based on the Conroe Core 2 Duo architecture core switch to Socket 775 interface, the mainstream models of front-side bus up to
1066MHz FSB, while the Extreme Edition version is further enhanced to strengthen
133
3MHz FSB, and shared 2 cache to 4MB;
only some of the low-end models will continue to use the 800MHz FSB and 2MB shared secondary cache.。 。.
AMD dual-core processors. .
AMD dual-core processor launched are dual-core Opteron series and new Athlon 64 X2 (information on the article price comments) series processor. One of the Athlon 64 was used in the contend X2 Pentium D and Pentium Extreme Edition desktop dual-core processor series.
AMD introduced the Athlon 64 X2 Athlon 64 processors from the two adopted a combination of Venice core, each core has a separate 5
12KB (
1MB) L2 cache and execution units. In addition to more than a Core from the Athlon 64 architecture relative to the current structure is not any major changes. .
Athlon 64, Athlon 64 and ordinary X2..
Dual-core Athlon 64 X2 most of the specifications, functions and we are familiar with no difference between Athlon 64 architecture, meaning that the new Athlon 64 X2 dual-core processors still support the
1GHz HyperTransport bus specifications, and built-in support for dual channel Set the DDR memory controller. .
Intel dual core processor and the difference is that the Athlon 64 X2 two kernel does not need to go through the MCH coordination between each other.
AMD Athlon 64 in X2 dual-core processor's internal provides a Queue called Request System (System request queue) technology at work each core will be its request on the SRQ, when access to the resource after the request will be referred to the appropriate implementation of the core, which means that all processes are completed within the scope of the CPU core, and do not need to resort to external devices.
For dual-core architecture,
AMD's approach is two core integrated into the same piece of
Silicon core, while
Intel's dual-core processing means more like a simple two-core to do with it. And compared to
Intel's dual-core architecture,
AMD dual-core processor system does not exist between the two core transmission bottle
NECks. In this respect, therefore, Athlon 64 X2 architecture is much better than Pentium D architecture. .
AMD Athlon 64 X2 internal diagram.
Although, compared with
Intel,
AMD is not worried about Prescott core with such a large power consumption and heat, but also take into account the need for dual-core processors reduce power consumption mode.
AMD has not adopted this approach to reduce the frequency, but the use of 90nm process produ
CTS Athlon 64 X2 processors with the so-called Dual Stress Liner strained
Silicon technology used in conjunction with SOI technology, to produce higher performance , lower power transistors. .
AMD Athlon 64 X2 launched to bring users a processor is the most affordable bene
Fits is that you do not need to replace the platform will be able to use the new launched dual-core processor, as long as the old Motherboard upgrade the BIOS on the can, and
Intel dual core processor must replace the new platform can support over upgrade dual core system will save a lot of expenses.
