INTEL 2010 PROCESSORS

Intel® Multi-Core Technology(included in corei3,corei5,corei7)

Permanently altering the course of computing as we know it, Intel® multi-core technology provides new levels of energy efficient performance, enabled by advanced parallel processing and 2nd generation high-K + metal gate 32nm technology. Incorporating multiple processor execution cores in a single package delivering full parallel execution of multiple software threads, Intel multi-core technology enables higher levels of performance, dividing the power typically required by a higher frequency single core processor with equivalent performance.
With Intel® Turbo Boost Technology, depending upon the work load, the power and frequency can be distributed across many cores or focused on fewer cores through the use of power gating—an internal power management unit that can “turn off” power to entire cores. An Intel® Turbo Boost Technology enabled processor can boost performance on the core or cores still active by raising the clock speed. Intel® Hyper-Threading Technology(Intel® HT Technology) can additionally increase efficiency by executing two software threads on a single core to get more done with less power than if separate cores were active. Together, these technologies provide a breakthrough experience in performance and responsiveness for notebook and desktop PCs, workstations, and servers.
By innovating future architectures that can hold dozens or even hundreds of processors on a single die, we're ensuring that Intel® technologies will continue to keep pace with demands well into the future.

Two, four, eight, and more cores

Current 32nm Intel® technology provides for one, two, four, and eight cores in a single processor. And Intel has already demonstrated a 32nm-based six core desktop processor to be introduced in 2010. Ideal for multitasking and multimedia, Intel multi-core technology delivers exceptional energy efficient performance for the ultimate computing experience.

All the new intel core processors except the core i3 series comes with an intel turbo boost technology.

Intel® Turbo Boost Technology Performance on demand

Intel® Turbo Boost Technology is one of the many exciting features that Intel has built into latest-generation Intel® micro architecture codename Nehalem. It automatically allows processor cores to run faster than the base operating frequency if it's operating below power, current, and temperature specification limits.

Dynamically increasing performance

Intel Turbo Boost Technology is activated when the Operating System (OS) requests the highest processor performance state (P0).
The maximum frequency of Intel Turbo Boost Technology is dependent on the number of active cores. The amount of time the processor spends in the Intel Turbo Boost Technology state depends on the workload and operating environment.
Any of the following can set the upper limit of Intel Turbo Boost Technology on a given workload:

• Number of active cores
• Estimated current consumption
• Estimated power consumption
• Processor temperature

When the processor is operating below these limits and the user's workload demands additional performance, the processor frequency will dynamically increase by 133 MHz on short and regular intervals until the upper limit is met or the maximum possible upside for the number of active cores is reached.
Also it includes hyper threading technology.

Intel® Hyper-Threading Technology (Intel® HT Technology)

Today's Intel® Hyper-Threading Technology (Intel® HT Technology)¹ delivers thread-level parallelism on each processor resulting in more efficient use of processor resources—higher processing throughput—and improved performance on multi-threaded software.
An Intel® processor and chipset combined with an OS and BIOS supporting Intel® HT Technology allows you to:

• Run demanding applications simultaneously while maintaining system responsiveness
• Keep systems more secure, efficient, and manageable while minimizing impact on productivity
• Provide headroom for future business growth and new solution capabilities

Enabling better graphics

With Intel HT Technology multimedia enthusiasts can create, edit, and encode graphically intensive files while running background applications such as virus protection software without compromising system performance.

Improving business efficiency

With Intel HT Technology, multi-threaded software applications can execute threads in parallel within each processor core. When Intel HT Technology and Intel® Turbo Boost Technology are combined in processors based on Intel® Microarchitecture, codenamed Nehalem, intelligent server processors deliver better performance by adapting to the workload and automatically disabling inactive cores and increasing processor frequency on remaining cores to get the tasks done quicker.
With Intel HT Technology, businesses can:

• Improve business productivity by doing more simultaneously without slowing down
• Provide faster response times for Internet and e-commerce applications, enhancing customer experiences
• Increase the number of transactions that can be processed simultaneously
• Utilize existing 32-bit applications technologies while maintaining 64-bit future readiness 

 We can expect tera scale computing in the future thats what intel has in its vision..........
which they will achieve through the 'single chip cloud computer'.......

Intel Labs has created an experimental “Single-chip Cloud Computer,” a research microprocessor containing the most Intel Architecture cores ever integrated on silicon CPU chip – 48 cores. It incorporates technologies intended to scale multi-core processors to 100 cores and beyond, such as an on-chip network, advanced power management technologies and support for “message-passing.” Architecturally, the chip resembles a cloud of computers integrated into silicon.

Tera-scale Computing Research Vision
By scaling multi-core architectures to 10s to 100s of cores and embracing a shift to parallel programming, we aim to improve performance and increase energy-efficiency.
"Tera" means 1 trillion, or 1,000,000,000,000. Our vision is to create platforms capable of performing trillions of calculations per second (teraflops) on trillions of bytes of data (terabytes).
