Multitask applications faster and unleash incredible digital media creation. An unprecedented four-core, eight-thread design with Intel Hyper-Threading Technology ensures incredible performance, no matter what your computing needs.

And enjoy incredible performance on other multimedia tasks like image rendering, photo retouching, and editing. By distributing All , physics, and rendering across eight software threads, the Intel Core i7 processor lets you concentrate on taking down the bad guys while your PC handles all the visual details such as texturing and shading that keep you feeling totally immersed.

The introduction of new Intel R Core TM i7, i5 and i3 chips coincides with the arrival of Intel's groundbreaking new 32 nanometer nm manufacturing price- which for the first time in the company's history - will be used to immediately produce and deliver processors and features at a variety of price points, and integrate high-definition graphics inside the processor. More than laptop and desktop PC platform designs are expected from computer makers based on these products, with another expected for embedded devices.

New Intel Core processors are manufactured on the company's 32nm process, which includes Intel's second-generation high-k metal gate transistors. This technique, along with other advances, helps increase a computer's speed while decreasing energy consumption. For the first time, there's a new family of Intel processors with the industry's most advanced technology available immediately at virtually every PC price point said Sean Maloney, executive vice president and general manager of the Intel Architecture Group.

They become energy efficient to the point of shutting down processing cores or reducing power consumption to provide performance when people need it, and energy efficient when they don't. In addition, ultra-thin laptops with all new Intel Core processors inside provide a balance of performance, style and long battery life for sleek systems less than an inch thick.

New Intel Core i7 and Core i5 processors also feature exclusive Intel Turbo Boost Technology for adaptive performance, and thus smarter computing.

Intel Turbo Boost Technology automatically accelerates performance, adjusting to the workload to give users an immediate performance boost when needed. In R Hyper-Threading Technology , available in Intel Core i7, Core i5 and Core i3 processors, enables smart multi-tasking by allowing each processing core t run multiple "threads," providing amazing responsiveness and great performance, balanced with industry-leading energy efficiency when processing several tasks simultaneously.

Supporting the all new Intel Core TM processors, the Intel 5 Series Chipset is the company's first single-chip chipset solution, evolving from simply connecting components to providing a range of platform innovation and capabilities. Another intuitive feature available to mainstream notebook buyers includes Intel Switchable Graphics, which allows users who play very graphics-intense games to automatically switch between Intel's integrated graphics to a discrete version on the fly, without having to re-boot, for optimal battery life and performance.

This design uses multiple cores like its predecessor, but claims to improve the utilization and communication between the individual cores. This is primarily accomplished through better memory management and cache organization. Some benchmarking and research has been performed on the Nehalem architecture to analyze the cache and memory improve-mints.

In this paper I take a closer look at these studies to determine if the performance gains are significant. But as more cores and processors were added to a high-performance system, some serious weaknesses and bandwidth bottlenecks began to appear.

After the initial generation of dual-core Core processors, Intel began a Core 2 series processor which was not much more than using two or more pairs of dual-core dies. The cores communicated via system memory which caused large delays due to limited bandwidth on the processor bus Adding more cores increased the burden on the processor and memory buses, which diminished the performance gains that could be possible with more cores.

The new Nehalem architecture sought to improve core-to-core communication by establishing a point-to-point topology in which microprocessor cores can communicate directly with one another and have more direct access to system memory.

The approach to the Nehalem architecture is more modular than the Core architecture which makes it much more flexible and customizable to the application. The architecture really only consists of a few basic building blocks. With this flexible architecture, the blocks can be configured to meet what the market demands. For example, the Bloom-field model, which is intended for a performance desktop application, has four cores, an L3 cache, one memory controller and one QPI bus controller.

Server microprocessors like the architecture the reorder buffer has been greatly increased to allow more instructions to be ready for immediate execution. Instruction Set Intelalsoaddedsevennewinstructionstotheinstructionset. For example, a few instructions are used explicitly for efficient text processing such as XML parsing. Another instruction is used just for calculating check-sums. Power Management For past architectures Intel has used a single power management circuit to adjust voltage and clock frequencies even on a die with multiple cores.

With many cores, this strategy becomes wasteful because the load across cores is rarely uni-form. Looking forward to a more scalable power management strategy, Intel engineers decided to put yet another processing unit on the die called the Power Control Unit PCU. Out-of-order execution Out-of-order execution also greatly increases the performance of the Nehalem architecture.

This feature allows the processor to fill pipeline stalls with useful instructions so the pipeline efficiency is maximized.

Intel is the only company with the manufacturing resources to take this next step so quickly. This translates into excellent volume pricing and consistent supply. The industry will be able to make a fast transition as well—these quad-core processors are designed to plug into current motherboards meeting the proper thermal and electrical specifications.

Our researchers are addressing the hardware and software challenges of building and programming systems with dozens even hundreds of energy-efficient cores with sophisticated memory hierarchies to deliver the performance and capabilities needed by these systems.

Four dedicated, physical threads help operating systems and applications deliver additional performance, so end users can experience better multi-tasking and multi threaded performance across many types of applications and work loads. Hyper-Threading duplicates the architectural state on each processor, while sharing one set of execution resources. This duplication allows a single physical processor to execute instructions from different threads in parallel rather than in serial, potentially leading to better processor utilization and overall performance.

However, sharing system resources, such as cache or memory bus, may degrade system performance. Previous studies have shown that Hyper-Threading can improve the performance of some applications, but not all. Performance gains may vary depending on the cluster configuration, such as communication fabric or cache size, and on the applications running on the cluster.

For optimal performance, in most cases the number of processes spawned is equal to the number of processors in the cluster. Therefore, parallelized applications can benefit from Hyper-Threading, because doubling the number of processors means the number of processes spawned is doubled, allowing parallel tasks to execute faster. Delivers two processing threads per physical core for a total of eight threads for massive computational throughput.

With more threads available to the operating system, multitasking becomes even easier. This amazing processor can handle multiple applications working simultaneously, allowing you to do more with less wait time. Get more performance automatically, when you need it the most. This result in increased performance of both multi-threaded and single-threaded workloads. The maximum frequency is dependent on the number of active cores and varies based on the specific configuration on a per processor number basis.

When temperature, power or current exceed factory configured limits and you are above the base operating frequency, the processor automatically steps down core frequency The processor then monitors temperature, power, and current and continuously re-evaluates. All active cores in the processor will operate at the same frequency. Even at frequencies above the base operating frequency, all active cores will run at the same frequency and voltage.

This is not reflective of actual core frequency. This means workloads that are naturally lower in power or lightly threaded may take advantage of headroom in the form of increased core frequency.

Continual measurements of temperature, current draw, and power consumption are used to dynamically assess headroom. In the Core architecture, each pair of cores shared an L3 cache. This other cache should be updated somehow if the line changes. Intel Advanced Smart Cache. The shared L2 cache is dynamically allocated to each processor core based on workload.

This efficient, dual-core optimized implementation increases the probability that each core can access data from fast L2 cache, significantly reducing latency to frequently used data and improving performance. One of its biggest changes will be the implementation of scalable shared memory. Instead of using a single shared pool of memory connected to all the processors through FSBs and memory controller hubs, each processor will have its own dedicated memory that it accesses directly through an Integrated Memory Controller.

In cases where a processor needs to access the dedicated memory of another processor, it can do so through a high-speed Intel QuickPath Interconnect that links all the processors.

A big advantage of the Intel QuickPath Interconnect is that it is point-to-point. It also improves scalability, eliminating the competition between processors for bus bandwidth. Nor is it the irst time Intel has used an integrated memory controller. Next generation micro architecture-based platforms will simply be the first to bring both scalable shared memory and integrated memory controllers together. With each processor having its own memory controller and dedicated memory, the local memory will always be the fastest to access.

But not much—Intel QuickPath Interconnect is extremely fast. This means they schedule processes and allocate memory to take advantage of local physical memory and improve execution performance. Most virtualization software is also written to take advantage of scalable shared memory, pinning a virtual machine to a speciic execution microprocessor and its dedicated memory.

Intel QuickPath Interconnect uses up to 6. Gig transfer refers to the number of data transfers. Intel QuickPath Interconnect reduces the amount of communication required in the interface of multi-processor systems to deliver faster payloads.

The dense packet and lane structure allow more data transfers in less time, improving overall system performance. The link level retry retransmits data to make certain the transmission is completed without loss of data integrity. For advanced servers which require the highest level of RAS features, some processors include additional features including the following: self-healing links that avoid persistent errors by re-configuring themselves to use the good parts of the link; clock fail-over to automatically re-route clock function to a data lane in the event of clock-pin failure; and hot-plug capability to enable hot-plugging of nodes, such as processor cards.

Integrated Memory Controller Advantages The Integrated Memory Controller is specially designed for servers and high-end clients to take full advantage of the Intel QuickPath Architecture with its scalable shared memory architecture. The independent high-bandwidth, low-latency memory controllers are paired with the high-bandwidth, low-latency Intel QuickPath Interconnects enabling fast, eficient access to remote memory controllers.

The Integrated Memory Controller has the signiicant advantage of being coupled with large high-performance caches. This relieves pressure on the memory subsystem and lowers overall latency. Intel HD Boost Includes the full SSE4 instruction set, significantly improving a broad range of multimedia and compute-intensive applications. The bit SSE instructions are issued at a throughput rate of one per clock cycle allowing a new level of processing efficiency with SSE4-optimized applications.

A multi-core processor is a single computing component with two or more independent actual central processing units called "cores" , which are the units that read and execute program instructions. The instructions are ordinary CPU instructions such as add, move data, and branch, but the multiple cores can run multiple instructions at the same time, increasing overall speed for programs amenable to parallel computing. Manufacturers typically integrate the cores onto a single integrated circuit die known as a chip multiprocessor or CMP , or onto multiple dies in a single chip package. Processors were originally developed with only one core. A dual-core processor has two cores e. Intel Xeon E
