Amazing World Of Intel Technologies

In the current world, the use of computers increases rapidly which is all beyond the imaginations. And Intel plays an important role in this process as we can all see. Intel introduces a number of advance technologies in the field of processors day after day. Even a common man can’t able to use the current technology as a whole and in this time period they introduce a new one. The same thing is happened with Intel core i3 and i5 and i7. In a short period of time Intel introduces these three technologies. Here we discuss Core i7 technology.
Intel’s i7 cores are the high end model cores built with the new Nehalem microarchitecture, and although they have different editions available they are all capable of remarkable performances. They have speed, power, hyper threading and turbo boost available, and if you need that capability the i7 cores are what you should buy. Bright Hub’s expert writers have not only analyzed the strengths and weaknesses of the different editions, they inform you which will best suit your ne
Intel used to split the Core i5 processor brand into two different lines, one of which was dual-core and one of which was quad-core. This was, needless to say, a bit confusing for buyers.
Thankfully, the behavior has stopped (for now). All Sandy Bridge Core i5 processors are quad-core processors, they all have Turbo Boost, and they all lack Hyper-Threading. Most of the Core i5 processors, besides the K series (explained later) us the same 2000 series IGP with a maximum clock speed of 1100 MHz and six execution cores.
In the i3 vs i5 vs i7 battle, the Core i5 processor is now obviously the main-stream option no matter which product you buy. The only substantial difference between the Core i5 options is the clock speed, which ranges from 2.8 GHz to 3.3 GHz. Obviously, the products with a quicker clock speed are more expensive than those that are slower.
Core i7 Series
The Intel Core i7 series has also been cleaned up. In fact, it has perhaps been cleaned up too much, because at the moment Intel is offering only two Sandy Bridge Core i7 processors.
These processors are virtually identical to the Core i5. They have a 100 MHz higher base clock speed, which is inconsequential in most situations. The real feature difference is the addition of hyper-threading on the Core i7, which means that the processor will appear as an 8-core processor in Windows. This improves threaded performance and can result in a substantial boost if you’re using a program that is able to take advantage of 8 threads.
Of course, most programs can’t take advantage of 8 threads. Those that can are almost usually meant for enterprise or advanced video editing applications – 3D rendering programs, photo editing programs, and scientific programs are categories of software frequently designed to use 8 threads. The average user is unlikely to see the full benefit of the hyper-threading feature. In the Core i3 vs i5 vs i7 battle, the i7 has limited appeal.

These are some of the processors of Core i7 technologies:
  • Intel® Core™ i7-990X Processor Extreme Edition (12M Cache, 3.46 GHz, 6.40 GT/s Intel® QPI)
  • Intel® Core™ i7-980X Processor Extreme Edition (12M Cache, 3.33 GHz, 6.40 GT/s Intel® QPI)
  • Intel® Core™ i7-975 Processor Extreme Edition (8M Cache, 3.33 GHz, 6.40 GT/s Intel® QPI)
  • Intel® Core™ i7-965 Processor Extreme Edition (8M Cache, 3.20 GHz, 6.40 GT/s Intel® QPI)
  • Intel® Core™ i7-940XM Processor Extreme Edition (8M Cache, 2.13 GHz)
  • Intel® Core™ i7-920XM Processor Extreme Edition (8M Cache, 2.00 GHz)

All Intel® Core™ i7 processors Extreme Edition feature:
  • Intel Turbo Boost technology
  • Intel Virtualization technology
  • Enhanced Intel SpeedStep technology
  • Execute Disable Bit
  • Intel  64 architecture
