- Core - i7 Desktop edition is first released by intel in november 2008
- This processor is based on Nehalem Architecture.
- Nehalem processors use 45 nm technology
- This Architecture allows the processor to work at extremely high clocks
- More energy efficiency is achieved with this Architecture
- Later some xenon processors, i5 and i3 were also built basing on this architecture
Hyper Threading Technology - HT Technology
- This is the term used by intel in its multi threading processors
- With this technology the parallel processing can be improved. That is the number of processes that can run at the same time can be improved
- Hyper Threading technology works by logically duplicating a processor. That is it creates virtual processors inside an existing processor.
- Then the operating system of that computer assigns a particular task to each virtual processor. Then all the tasks will be running simultaneously with in the same processor
- Hence the performance of the system will be increased
- When it comes to core-i7. There will be 6 independent processor cores inside i7 processor. When the Hyperthreading technology comes to picture it creates virtual processor inside all the 6 processors. Then there will be too many virtual processors.
- Then the operating system will allocate each virtual processor a particular task
- Then all these tasks will get completed simultaneously.
- There by core-i7 will have ultimate performance....
Intel Turbo boost Technology
- This technology is implemented in certain versions of core-i5 and core-i7
- This technology is used to increase the processor clock( to boost up the speed of processor) when there is a demand (i.e, any application which is heavy sized and demands high performance)
- Turbo boost is activated when ever there is a demand form the operating system
- When ever Turbo boost is activated the processor speed is increased in increments of 133 Mhz. The speed of the processor is increased until the processor reaches to the saturation level or thermal limit or maximum power limit.
- Processor performance and speed are handled by ACPI. (Advanced Configuration and Power Interface)
- ACPI is already included in all the major operating systems. Hence it does not require additional software or drivers support.
- For example: If a processor is running at a speed of 3.06 GHz and its maximum clock is 3.5GHz under certain conditions. If an application demands performance, then the processor's clock will be boosted up to 3.193GHz first i.e., 133Mhz is added to the existing clock. Then again to 3.226GHz, and so on upto 3.5Ghz. Hence the processor performance will be enhanced tremendously.
Multicore Technology
- Multicore technology is the technology where two or more processor cores are put together into a single processor chip.
- Then the processor is said to be a multicore processor. Core i7 is a multicore processor with 7 cores in it. Out of which 6 processors are general purpose processors and one additional Graphic processing unit (GPU) is added which accounts to the 7th core.
