Many people don’t know the difference between Core i7, Core 2 Extreme, Core 2 Quad, Core 2 Duo, Dual core and Pentium D processors. You can call this a processor buying guide. So lets understand this in detail.
Core 2 Quad is a 4 core processor unlike Dual core which has 2 cores. Core 2 Duo, Dual core and Pentium D, all are dual core processors only. Cores are also called processing cores. Like Pentium 4 is a single core processor. Ofcourse performance of Core 2 Quad is the best compared to all dual core processors. Some Core 2 Quad models also have 12 MB of L2 cache, runs on 3 GHz and 1333 MHz FSB. Now this is what we call a great performance. I am talking here about Q9650 processor.
Some Core 2 Duo processors also have upto 6 MB L2 Cache and 1333 MHz FSB. Core 2 Duo are also dual cores or you can say they have two cores. These are based on 65 nm and 45 nm manufacturing process. A real value for money Core 2 Duo is E7200/E7300. Read on this article.
Now lets talk about Core 2 Extreme and Core i7. Core 2 Extreme has 12 MB L2 cache, runs on 3.2 GHz and has FSB of 1600 MHz. These specs are of QX9775, which is based on 45 nm manufacturing process. Core i7 is the latest processor. In simple terms, the best performer till now. Yes I mean the best performer in the whole processor family till now. Call it Core i7 or Nehalem, if you have some extra bucks then definitely go for this. Keep in mind that motherboard for Core i7 is also very expensive. If you are going to buy this then consider the overall cost of Processor, Motherboard and RAM. RAM used in this Motherboard for Core i7 is DDR3. So RAM is also expensive for now. But if you just forget the cost of owning this beast/beauty then its a real winner in performance. Learn more about Core i7 here. Nowadays Core i7 Extreme Edition is also released, model number i7 – 965. It runs on 3.20 GHz & has 8 MB cache size. Core i7 Extreme Edition is the fastest performing processor on the planet.
Lets arrange these processors in ascending order of their performance. I mean the best performer first and the lesser the second and it goes like this.
Core i7 Extreme Edition
Core 2 Extreme
Core 2 Quad
Core 2 Duo
For now if you want something low on budget and a real value for money then you can go for Intel Dual Core E2180. I have done these processor comparison by keeping only Intel in mind. Whatever you buy, buy it by keeping the purpose of usage in mind and some of these processors also run hot and then comes over-heating problems. So consider all these aspects before buying.
More info AMD processors coming soon as AMD processors have a different naming scheme.
