Intel Core i7 vs Intel Core 2 Duo – The Difference

With the launch of the new Core i7 (Nehalem) processors by Intel, there are many doubts regarding the Difference between Intel Core i7 and Intel Core 2 Duo and Core 2 Quad processors. In this post, I will try to list all the differences and also reasons why the new Core i7 architecture is much better than the Core 2 architecture.

Intel Core i7

Codenamed: Bloomfield – Nehalem
Fabrication: 45 nm
Instruction set: X86, X86-64, MMX, SSE 4.2
Socket: LGA 1366
Bus: Quick Path Interconnect
RAM: DDR3
Chipset Support: X58


Intel Core 2 Duo

Codenamed: Conroe, Allendale, Wolfdale – Core 2
Fabrication: 65 nm / 45 nm
Instruction set: X86, X86-64, MMX, SSE 4.1
Socket: LGA 775
Bus: 1333 MHz FSB
RAM: DDR2
Chipset Support: 965, P3x, G3x, P45, X48




Explanation:
(Difference between Intel Core i7 and Core 2 Duo)

-
The Core i7 is a completely new architecture which is much faster and more efficient than the Core 2 Duo. Currently only the Core i7 920, 945 and 965 XE versions are available. Of that the Core i7 920 is available at just $284 which makes it a great buy. It offers better performance than almost all Core 2 Duo processors.

Native Quad Core, More Cache and Hyper Threading:

All the Core i7 processors are Native Quad cores (4 cores), which means that they actually have 4 cores on a single die, while the older Core 2 Duo processors like the Q6600 (2×2 = 4 cores) had two cores on a single die, and two such dies merged together. This increases the processing speed greatly. They also have 256 KB L2 cache per core and a shared 8 MB L3 cache which has proven to be much better than any cache configuration in Core 2 Duo.

It also has HyperThreading support which means that each of the 4 cores can process 2 threads simultaneously, so you get 8 virtual cores. This helps in running many applications parallely and also in gaming.

Quick Path Interconnect (QPI) and On Die Memory Controller:

The Core i7 processors sport the new Quick Path Interconnect technology which replaces the FSB (Front Side Bus) to connect the various components in a computer. QPI is much faster than FSB and hence improves the overall performance. It is even faster than AMD’s similar HyperTransport 3.0 standard.

The Core i7 have an On Die Memory Controller which means that it can access memory much faster than the Core 2 Duo processors which had an external memory controller. Intel has borrowed this feature from AMD. All the four cores, memory controller, cache are on the same die which improves the speed and performance greatly.




Intel X58 Chipset and DDR3 RAM:

The new Core i7 processors work with Intel’s newest X58 chipset motherboards – these are the best currently available and have superb features like PCI Express 2.0, Support for both AMD’s Crossfire and Nvidia’s SLI to use two graphic cards simultaneously. The combo of Intel X58 and Core i7 also runs much cooler and consumes much less power than the older Core 2 Duo processors. Also the new Core i7 and X58 combo supports only the super fast DDR3 RAM which is becoming cheaper day by day.

These are the main differences between the Intel Core 2 Duo and the Core i7 processors. AMD doesn’t seem to have a decent processor coming up which could compete with Intel’s new Core i7 – the new king. The new Core i7 processors beat every other processor when it comes to performance and are also much more power efficient. They are better for gaming and other tasks. They also overclock better than any Intel or AMD processor.

So if you are planning to buy a new PC, I would suggest you to get a Core i7 based one. Core i7 920 + Intel X58 based motherboard + 1-2 GB DDR3 RAM should cost you about $600.

Some of the a lot of accepted 11-inch systems cover the ASUS U2E, Lenovo IdeaPad U110, and Sony VAIO TZ series, which appear accepted with 1366 x 768 pixels and no added affectation option. This resolution offers a acceptable antithesis amid awning absolute acreage and the ad measurement of icons and text, but you'll pay a exceptional for the awning size. For continued accretion sessions, 12-inch screens are just added able than 11-inch options.

You'll acquisition a bit added array in the 12-inch range, but resolutions are abundantly bound to one best for any accustomed notebook. For a arrangement this size, 1024 x 768 pixels provides able resolution for basal productivity, which you'll acquisition on ultra portables such as the Lenovo Think Pad X61s. If you wish added resolution, footfall up to 1280 x 800 pixels, which is bigger for multimedia applications and accessible in high-end, failing machines including the ASUS Lamborghini VX3-A1 and Fujistu Life Book P8010.

13.3 to 15.4 inches: All-Purpose Laptop

In this chic of Laptop, resolutions ambit from 1280 x 800 up to high-definition 1920 x 1200 on high-end gaming systems. For accustomed accretion chores, 1280 x 800 pixels is fine, and you'll acquisition it on accepted 13.3-inch systems such as the Apple Mac Book, Dell XPS M1330, Sony VAIO CR, and Toshiba Satellite U405.

That aforementioned resolution is accepted as you move up to 14- and 15-inch Laptop, but there are some notable exceptions. For example, the 14.1-inch Dell Inspiron 1420 and the 15.4-inch Inspiron 1525 accept a $50 advantage to advancement the console to 1440 x 900 or 1680 x 1050 pixels, respectively, which should accommodate added desktop absolute acreage and added data for tasks like photo editing, admitting with abate icons and text. The 15.4-inch Mac Book Pro has a 1440 x 900-pixel display, which is acceptable for artistic pros on the go.

As you move into 15-inch multimedia Laptop and gaming systems, such as the Alien ware Area-51 m15x and Dell XPS M1530, you'll see higher-resolution LCDs. In the case of Dell's M1530, affective up to 1440 x 900 pixels costs $50 (plenty of eye bonbon for the latest 3D titles), and the high-definition 1920 x 1200-pixel affectation costs $100 more. Note that this resolution may be abstract accustomed the mid range 256MB Nvidia cartoon agenda and that you won't see the accurate account of the $500 Blu-ray Disc advantage on a 15.4-inch screen.

The Best Antivirus Program Available - Why Its Kaspersky For Me

I am a heavy computer and Internet user that is why I am very careful when it comes to viruses. I know that these critters can be very annoying, not to mention that that they can destroy precious files on your computer. I have been hit by a virus once and it is such a pain. I ended up re-formating my hard drive which was really a drag. I had to replace all the programs that was in my computer which set me back several hundreds of dollars. But you know why I was hit with a virus then? Its because my computer before does not have an antivirus program installed. But now I have learned my lesson. My computer is now protected with what for me is the best antivirus program available, the Kaspersky antivirus.

Before I say why I think Kaspersky is the best antivirus program, let me first tell you my criteria for choosing the best antivirus program. For me, the best antivirus program must, first and foremost be effective in removing viruses and other malware. Kaspersky cannot be beat when it comes to getting rid of viruses. In a test that I have done, Kaspersky has removed 67% of all malware while in normal mode and almost 100% when set in safe mode. Others, in comparison, was able to remove only a little more than half on the average.

Another important thing for me that an antivirus program must have is efficiency when it comes to using computer resources especially the random access memory or RAM. Some of the more effective antivirus programs are very greedy when it comes to using resources. When Kaspersky is running in the computer you barely notice it since it uses very little resources and therefore does not affect computer performance.

I am very much satisfied with Kaspersky that's why I think it is the best.

How to Make a Computer Run Fast Without Upgrades

Computers are annoying when they run slow - they prevent you from being able to do everything from watch movies to play games to even doing your work. This is a massive problem with millions of computers suffering from it all over the world... but luckily, there's a simple way to make it run faster which even a computer novice can do.

Speeding up your PC without upgrades is actually very simple. It's all a case of making your PC work better with the technology that it has already, instead of trying to boost it to deal with more problems. Computers all work at a speed that they were made to, and over time, this speed decreases as more and more junk files accumulate on your system.

When your PC was new, it had no files or folders which were making it run slow. Instead, it was able to find all the files it needed and was happily running at its optimum speed. As time has progressed, your computer has gathered many files which create "file traffic jams" inside it, making your computer take longer to read the files it needs, slowing it down. These junk files are created when your computer gets confused and saves them in the wrong way. This makes your computer take longer to read them, which slows it down. The more files that are jamming up your system like this means the more files that are slowing your PC down, meaning that over time, your computer will eventually run at a snail's pace.

This problem is the biggest cause of a slow system and is very easy to reverse without any expensive upgrades. You simply need to use a tool called a 'registry cleaner' to scan through all your computer's files and fix the problems that are in there. Basically, this tool scans all your computer's system files and then fixes or replaces the ones that are corrupt and damaged. This allows your PC to quickly find the files it needs, allowing it to run at the same speed it did when it was new.

Using a registry cleaner to make your computer fast, is actually one of the easiest and most over-looked ways of speeding up your system. We've found the best registry cleaner to do this is called RegAce
