Processor Comparison – Part 15 of 16

If you are a normal user and dont do alot of number crunching, you may not find a significant difference between these processors in day to day use but if you are a power user and do a lot of DVD ripping, video conversion, extreme 3d gaming, mp3 and video editing, photo conversion, programming or even file compression (zip or rar etc), you will need a faster processor. Go for a top of the line processor if your current machine is out of date but the price of these processor drops faster than the apple falling from a tree. So watch out and dont spend too much on a processor.

I’ve tried to simplify the comparison between these processors in this article but if you think not enough detail has been given, please go through the following table that has been taken from Intel’s website and it compares five different processors, one example from one technology each.

Difference between L2 Cache and Intel Smart Cache

Intel Processor Comparison – Part 14 of 16

Intel Core i3, i5 and i7 use Intel Smart Cache while older processors have been using L2 Cache. I have failed to find anything special in terms of feature of this smart cache. Intel belives that this Smart Cache is smarter than L2 cache but I believe that it is more of a marketing team terminology and is hardly any better than the conventional L2 cache. Please do let me know if you know something better than that about Smart Cache, please do let me know.

Difference between FSB and DMI

Intel Processor Comparison – Part 13 of 16

Front Side Bus
Front Side Bus

Front Side Bus

FSB is a BUS technology that is used in Core 2 Quad/Duo processor technologies and earlier. FSB allows the processor to communicate with other components of the computer including Memory, PCIe, Video as well as IO devices like USB, Hard disk, Network etc. Everything that goes in and out of the processor goes through FSB. See the diagram below to see a typical Core 2 Duo processor and FSB communication channels.

DMI – Direct Media Inteface

Core i7 running on DMI
DMI Technology

DMI bus technology is used in Intel Core i3, i5 and i7 processors. The basic difference in architecture is, that the processor communicates over a different channel with RAM, a different channel with PCIe and a third channel DMI to communicate with all other components of the computer. This increases the performance significantly. See diagram below for a typical Core i7 architecture.

Difference between Core 2 Technology vs Core i Technology

Intel Processor Comparison – Part 12 of 16

Intel Core 2 Quad and Core 2 Duo technology have some more differences as compared to Intel’s Core i3, i5 and i7 technologies. Core 2 technology supports L2 cache while Core iX processors run Intel Smart Cache technology. Similarly, architectural change in bus architecture is also a difference. Core 2 processors use FSB (Front Side Bus) while Core i processors use Intel Smart Cache.

Difference Between Core i5 and Core i7

Intel Processor Comparison – Part 11 of 16

Am I getting redundant here? Not really. Intel Core i5 is a quad core processor that can run four processes at a time, while each process can run only one thread. While Intel Core i7 can run four processes and eight threads at the same time on its four cores. So you can say that Core i5 has uni-threaded four cores, while Core i7 is a quad core processor with each core running hyper threading technology.

Difference Between Core i3 and Core i5

Intel Processor Comparison – Part 10 of 16

Intel Core i3 is a dual core processor while Core i5 is a quad core processor. While Core i3 can run total of 4 threads and 2 processes at a time, Core i5 can run 4 threads and 4 processes at a time. Intel Core i3 is necessary a next version of Core 2 Duo while Core i5 is the next version of Core 2 Quad.

Intel Turbo Boost Technolog

Intel Processor Comparison – Part 9 of 16

Intel Turbo boost technology is a smart way of over clocking the processors. Gamers and enthusiasts around the globe have been using tricks to overclock their processors to get better speeds. This fact has become so popular that Intel has included Turbo Boost as their native feature. Whenever the processor is over loaded and reached its 100% processing limit, Intel Turbo Boost tehcnology comes into play. It increases the processor’s core frequency by 133 MHz after random and frequent intervals. The processor frequency continues to increase till the upper limit for the processor Turbo is reached. The upper limit is the maximum overclocking frequency that is allowed by Intel. You may end up frying your processor if you dont stop there.

Difference Between Core 2 Quad and Core i5

Processor Comparison – Part 8 of 16

Core 2 Quad and Core i5 are both quad core processors, that is, four cores in one processor chip. This necessarily means, they can run four different processes at the same time. Both of them can run four threads at the same time too. Whats the difference then? The difference is somewhere else. The difference is Turbo Boost technology. Core 2 Quad does not have Turbo Boost Technology, while Intel Core 5 has Turbo Boost enabled.

Difference Between Core 2 Duo and Core i3

Intel Processor Comparison – Part 7 of 16

As Core 2 Duo technology has been here for some time, Core i3 is targetted to replace Core 2 Duo in the market pretty soon. Both Core 2 Duo and Core i3 are dual core processors and can run two processes at the same time. The main difference between these two is the number of threads. Two cores on Core 2 Duo are single threaded while Core i3 has a dual thread running capability on each core. Hence total number of threads that can run on Core 2 Duo is 2 and 4 threads in total can run on Core i3.
