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.

A 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 .

 

DELETE YOUR PC DATA PERMANENTLY

Most people have some data that they would rather not share with others – passwords, personal information, classified documents from work, financial records, self-written poems, the list continues.
Perhaps you have saved some of this information on your computer where it is conveniently at your reach, but when the time comes to remove the data from your hard disk, things get a bit more complicated and maintaining your privacy is not as simple as it may have seemed at first.
Your first thought may be that when you ‘delete’ the file, the data is gone. Not quite, when you delete a file, the operating system does not really remove the file from the disk; it only removes the reference of the file from the file system table. The file remains on the disk until another file is created over it, and even after that, it might be possible to recover data by studying the magnetic fields on the disk platter surface.
Before the file is overwritten, anyone can easily retrieve it with a disk maintenance or an undelete utility.
There are several problems in secure file removal, mostly caused by the use of write cache, construction of the hard disk and the use of data encoding. These problems have been taken into consideration when Eraser was designed, and because of this intuitive design and a simple user interface, you can safely and easily erase private data from your hard drive.

Eraser is an advanced security tool for Windows which allows you to completely remove sensitive data from your hard drive by overwriting it several times with carefully selected patterns. Eraser is currently supported under Windows XP (with Service Pack 3), Windows Server 2003 (with Service Pack 2), Windows Vista, Windows Server 2008, Windows 7 and Windows Server 2008 R2.

 AMD Bulldozer “FX-8150P Black Edition”

 

A Chinese site has leaked details on AMD’s upcoming Bulldozer based Zambezi-FX Processor. The Processors which is called “FX-8150P” would a top of the line “Black Edition” offering from the A-8 Series lineup which consist of 8 Cores. We already know that AMD has postponed their Bulldozer Launch to July-August due to performance issues with the current CPU revisions, Newer B2 Revisions will arrive shortly in early Q3 2011. Some websites detailed that the delay was part of AMD’s marketing strategy.

The CPU “FX-8150P Black Edition” is built on a 32Nm SOI process and will feature a base clock of 4.2Ghz and can turbo upto a staggering 4.7Ghz clock. Keep in mind that the fastest AMD CPU we knew till now was the FX-8130P with a 3.8Ghz stock and 4.2Ghz T.C but the Black edition breaks the barrier. The Processor features a whopping 140W TDP. Other specs are 1866Mhz DDR3 Memory support, Unlocked Mutiplier, 8C/8T and 8Mb L3 Cache. Reaching 5Ghz+ clock speeds wont be a biggie on this monster.

As far as the price goes, Not much has been detailed but considering the FX-8130P which will be available for 320$  The price of FX-8150P would be set at a 350$+ mark.
