<div dir="ltr" style="text-align: left;" trbidi="on"> Generally speaking the current generation of Core i3/i5/i7 have about 20% more processing power than their Core 2 Duo counterparts.<br /> <br /> Core i3:<br /> -Dual Core CPU<br /> -Hyper Threading<br /> <br /> Core i5:<br /> -Dual Core CPU<br /> -Slightly higher clock speeds than core i3<br /> -Hyper Threading<br /> -Turbo Boost (it's like an automatic overclock if the CPU is not too hot)<br /> <br /> Core i7:<br /> -Dual Core CPU (models ending with M)<br /> -Quad Core CPU (models ending with QM)<br /> -Higher clockspeed than the Core i5<br /> -Hyper Threading<br /> -Turbo Boost<br /> -Virtualization (you can run multiple operating systems at the same time)<br /> -Has circuitry that allows for easier and more secure remote access for corporate IT departments to trouble issues in a business environment.<br /> -AE5 New Instruction set (No idea what this is)<br /> <br /> <br /> If you are looking for an Intel core i3 i5 i7 comparison, this article will be a helpful read. This new family of Intel processors has taken the market by storm. The Intel core i3 vs i5 vs i7 comparison made in this article will help you decide what processor to opt for in your desktop or laptop computer.<br /> Intel has launched its new family of processors quite recently that has redefined all notions related to computing performance. This new family of processors consists of three classes – core i3, core i5 and core i7. While the Intel core i3 series has been made to cater to the entry level desktop and laptop computer market, the core i5 series is aimed at the mid-level computing segment. The core i7 series is stuffed with high performance processors that can serve the high end market. Every series of processors comes with a lot of variety, in terms of processing speed and features. In this article I make an Intel core i3 i5 i7 comparison that identifies the major points of difference between these classes of processors.<br /> <br /> <br /> Difference Between i3 i5 i7 Processors<br /> <br /> What set these new processor lines, developed by Intel, to be miles ahead of its closest competitors are the new technologies developed by Intel to boost performance. The synergy between multi-core processors achieved in Intel core i3, i5 and i7 is what sets them ahead of the rest of the pack. Here is an i3 i5 i7 comparison which discusses how the three processor lines differ in terms of features and performance.<br /> Intel Core i3 i5 i7 Comparison: Technical Features<br /> Let us have a look at the technical points of difference between i3, i5, i7 processors. Let’s start with the entry level processor line released in January 2010. All the core i3 processors have twin core with clocking frequency ranging from 2.933 GHz to 3.2 GHz. A 4MB L3 smart cache, 2 x 256 KB L2 cache and Direct Media Interface bus, fitted with the brand new LGA 1156 socket, makes them the best entry level processors. All these chips are built on a 32 nm architecture which ensures that more transistors can be etched on the silicon chips. An integrated GPU (Graphic Processing Unit) makes graphic processing even faster. With Intel’s hyper-threading and virtualization technology enabled, along with HD graphics, these chips are priced at $133 only.<br /> As the i3 i5 i7 comparison chart on the Intel web site reveals, core i5 line consists of three separate series of processors with twin and quad cores. The twin, as well as quad cores comes with 4 threads each. The clocking frequencies of these processors range from 2.4 GHz to 3.33 GHz, powered by the Intel Turbo boost technology that boosts clocking frequencies to higher levels when need be. With 4 MB to 8 MB L3 cache, direct media interface, integrated GPU, LGA 1156 socket, Intel HD graphics, Intel smart cache technology and Hyper-threading enabled, the cost of these processors ranges from $176 to $256. As a core i5 vs core i7 comparison will prove, i5 chips are faster than the i3 chips. They form the mid-level segment.<br /> With the core i7 line, Intel has fulfilled its dream of creating the ‘best processors on the planet’. In the core i3 vs i5 vs i7 comparison, core i7 is miles ahead of the rest of the pack. This line consists of quad core processors with clocking frequencies reaching 3.33 GHz powered by Intel Turboboost. As a quad core vs dual core comparison would prove, greater number of cores can immensely boost computing speeds.<br /> With L3 smart cache ranging from 8MB to as much as 12 MB, Intel QuickPath Interconnect technology (that can enhance data transfer speed to 25.6 GB/Sec), integrated GPU, Hyper-threading and Intel HD graphics, the core i7 series processors are indeed, unarguably, the best processors ever manufactured. They are meant for high end computing applications, web servers and high end business users. The price of these processors ranges from $200 to as much as $1000.<br /> <br /> Intel Core i3 i5 i7 Comparison: Performance<br /> Let us now make an Intel core i3 vs i5 vs i7 performance comparison. Besides being multicore, what makes the i3, i5, i7 processors to be computing power houses, is the hyper-threading technology, combined with the Turbo boost feature. An integrated GPU and an enhanced L3 cache make graphic processing super-fast. As an Intel core i3 vs core 2 duo comparisons would reveal, the i3 processors surpass the computing power offered by the earlier core 2 duo series. If you are eying an entry level laptop computer, go for the core i3 line. It is great for home used desktop computers too.<br /> <br /> If you are a business user, I suggest that you go for the core i5 line, that can handle multitasking even better than the i3 line. With hyper-threading enabled and Intel’s range of innovative technologies fully operational, the core i5 line is ideal for the business user or home users, who are into intensive gaming. If you want to settle for nothing less than the very best in computing today, go for the high end core i7 line. As you must have realized while going through the core i3 i5 i7 comparison, the i7 line puts phenomenal computing power at your fingertips that was available once only to users of supercomputers! Budget wise, they may be the costliest out of the whole lot, but they offer true value for your money.<br /> Hope this straightforward core i3 i5 i7 comparison has cleared out any doubts in your mind about these new Intel chips. This article is based on research on i3 i5 i7 benchmark tests. Choose any one of these three lines that suits your budget and computing requirements.<br /> Intel will stop selling Core 2 Duo and Core 2 Quad in 2010.
