Cores of Processor & Misconception about i3, i5, i7

The term core memory is a leftover from an early form of random access memory (RAM). Magnetic core memory  was first patented in 1947 and was used in early computers through the 50s and 60s. According to Wikipedia’s article, magnetic core memory was replaced by integrated silicon RAM chips in the 1970’s. Unlike modern silicon RAM, core memory was non-volatile — it retained its contents indefinitely without power.

multi-core processor is a single computing component with two or more independent actual processors (called “cores”), which are the units that read and execute program instructions.

Intel introduced a new naming scheme for its new Core processors. There are three variants, Core i3, Core i5, and Core i7, but the names no longer correspond to specific technical features like the number of cores. Instead, the brand is now divided from low-level (i3), through mid-range (i5) to high-end performance (i7), which correspond to three to five stars in Intel’s Intel Processor Rating as opposed to the entry-level Celeron (one star) and Pentium (two stars) processors.

For my curious friends !

  • Core i3 has 2 cores !
  • Core i5 has 2 or 4 cores !
  • Core i7 has 2,4 or 6 cores !

Now the question is how i3 is efficient then core 2 duo ?

Technically there are many differences but shortly what makes the big difference is the cache .

  • core i3 max cache = 4mb L3
  • core i5 max cache= 8mb L3
  • core i7 max cache =12mb L3

Processor earlier then i3 used L2 type cache .

Intel launches second generation core processors

World’s leading chip manufacturer Intel Thursday launched second generation intel core processors with built-in visual capabilities to deliver superior audio-visual experience, faster downloading ability and improved battery life.

‘The built-in visual capabilities enabled by these new processors are stunning. This combined with improved adaptive performance, will revolutionize the PC experience in a way that is obvious for every user to see and appreciate, a visibly smarter performance,’ said R. Sivakumar, managing director sales and marketing group, Intel South Asia.

 

‘The new features are bound to appeal to your senses and give you a better looking PC experience,’ he added.

Intel estimates that a 4-minute HD video that used to take 4 minutes to convert to play on an iPod would now take just 16 seconds.

 

The new processor technology focusses on high-definition videos, mainstream gaming, online socialising and multimedia and combines visual and 3D graphics technology with performance-leading microprocessors on a single chip.

Its new features include Intel Quick Sync Video, and a new version of the company’s award-winning Intel Wireless Display which now adds 1080p HD (high definition) and content protection for those wishing to beam premium HD content from their laptop screen to their TV.

 

More than 500 laptops and desktops designs based on these products are expected from all major computer makers worldwide.Systems are likely to be available from OEMs (original equipment manufacturer) like HCL, Wipro, HP, Lenevo, Toshiba and Dell among others as well as from local channel partners.

The company said that the price range of the products incorporated with the second generation intel core processors will increase marginally.
