Basic(Core) Knowledge of Computer & Knowledge about Processors (Dule Core, Core2Duo, i3, i5, i7)

Some Basic(Core) Knowledge  of Computer :

 

What is Core ?

• “Core” is a microprocessor inside the central processing unit (CPU), i.e. if you have a dual core then you have 2 microprocessor  in your CPU, as one microprocessor can only do one thing at a time, so it will allow you to do two things at a time.

What is Cache Memory ?

• Cache memory is RAM (Random Access Memory) that a computer microprocessor can access more quickly than it can access regular RAM.

Different Processors :

1) Intel Dual Core :

• It's the first dual-core CPU from Intel. The Dual core makes use of two cores on a single die i.e. it has two chips in one package. It solves the problem of overheating of Intel Pentium D without compromising on the performance.it was made by combining 2 Pentium processors  into one and the communication between these processes and cache was not as exactly as how you would expect from a dual core

• Pentium Dual Core, which has 1 MB cache, you might think, C2D is a better choice. However, think again when you see Pentium Dual Core will only cost you merely RM 200. (RM 200 cheaper to C2D same GHz)

2) Intel Core 2 Duo :

• Intel Core 2 Duo processors are the next gen processors from Intel. It is developed with a new Architecture called Core. The new architecture of Intel core2 duo makes it a lot better processor that runs cool. Most importantly the Intel core2 duo is a super over clocker.

• A Core 2 Duo on the other hand is also a Dual Core processor but it is manufactured by Intel and is part of the "Core 2" series. The "2" in the "Core 2" only means, that this series is from the second generation. There is, for example, the "Core 2 Quad", which obviously has 4 cores.

• In a nutshell :

1. Dual Core = general term for all processors with two cores
2. Core 2 = series of processors manufactured by Intel
3. Core 2 Duo = Intel processor  with two cores
4. Core 2 Quad = Intel processor with four cores

• Core 2 Duo processor has 2, 3, 4 or even 6 MB Cache, depend on the product code. The cheapest C2D has 2 MB cache, which around RM 400 right now.

3) Core i3 :

• Uses 4 threads, contains Hypo threading technology (Hyper Threading means used in certain Pentium 4 processors and all Intel Xeon processors.Enables the processor to execute two threads, or sets of instructions, at the same time. ).
• It has 2-4 cores.
• Contains a 3-4 MB Cache.
• i3 designed for low-mid range operation.
• Uses less heat and energy than earlier processors, which is always a good thing in this day and age.

4) Core i5 :

• Uses 2-4 threads, contains Turbo Boost(Enables the processor to run above its base operating frequency via dynamic control of the CPU's "clock rate") technology.
• It has 2-4 cores, higher clock speed than core i3.
• Contains a 3-8 MB Cache.
• i5 is good for med-high operation.
• This is also a heat and energy efficient processor, but it does seem to be better at this particular job than the Core i3 processor.

5) Core i7 :

• Uses 8 threads, Contains hypo threading &Turbo Boost both Technology (That enough to get the job done quickly).
• It has 4 cores, higher clock speed than core i3 and i5.
• Contains a 4-8 MB Cache.
• i7 great for high-ultra operation newest technology.
• It is also more energy efficient and produces less heat.
