As for now, we can see that Intel has three major processor families - Core, Pentium and Celeron. Among them, the high-end Intel core processors give the best performance that is suitable for gamers and those required high-performance PCs.
The mid-range Pentium processor reliable and suitable for normal day-to-day working as well as home users and the budget Celeron processor are entry-level choices for basic computing.
1.) Intel Core processor
The Intel core processors are preferred by most users now are it has the following advantages:
Speed when you need it
Your processor automatically gets a boost of performance when your PC needs it with Intel Turbo Boost Technology.
Superb visual performance
Enjoy a stunning visual experience that delivers sharper images, richer color, and lifelike audio and video,with Intel HD Graphics.
Broadband Internet on the go
Access broadband Internet all over town at speeds four-times faster than 3G with 4G WiMAX wireless technology.
Your PC now on your TV
Put all of your personal and online content on a big screen with Intel Wireless Display - the easy way to share laptop content on your TV.
Eliminate the wait
Stop waiting for your computer to catch up! Intel Hyper-Threading Technology lets you do more tasks at once.
The Intel Core processor is the smarter processors that automatically deliver extra performance whenever you need it. It is available in several performance levels:
Intel Core i7 processor (Info and best review on Core i7 CPU here)
The Core i7 processor no longer has a Front Side Bust (FSB) and it uses Quick Path Interlink (QPI) which measured in gigabytes per second (GB/s). The newest Core i7 also implements a new processor socket called LGA1366 which is incompatible with all earlier processors. The older Core i7 processor still uses the LGA 1156 socket same as Core i5 processor. All Core i7 CPU uses Intel's Hyper-Threading technology to boost performance which allows for 8 processing streams.
Intel Core i5 processor (Info and best review on Core i5 CPU here)
The Core i7 and i5 for socket LGA1156 are the same as a Core i7 1366 processor except that the socket uses a few less pins and the processors lack a little performance. Hence, it's little cheaper compare to Core i7. The Intel Core i5 processor has up to 8MB of Intel Smart Cache and it support Intel Hyper-Threading Technology and Turbo Boost Technology. This will automatically allocates processing power where it's needed most. Whether you are playing games, editing photos or music, this processor can multitask with ease and be more productive than ever.
Intel Core i3 processor
As the first level in Intel's new processor family, the Intel Core i3 processor is the perfect entry point for a fast, responsive PC experience. It uses socket LGA1156 with 4MB Smart Cache and it also features Intel Hyper-Threading Technology, which enables each core of your processor to work on two tasks at the same time, delivering the performance you need for smart multitasking.
Intel Core 2 Quad processor
The Core 2 series still implements a Front Side Bus which ranges from 1066 MHz to 1600 MHz for the quad cores. The L2 Cache for the Core 2 Quad can up to 12 MB. Core 2 Quad uses socket LGA775 and it does not use the Hyper-Threading technology so you are limited to 4 stream processes. This is the first processor socket to implement the pins for the CPU on the motherboard to help reduce the chance to bend pins.
2.) Intel Pentium Dual Core processor
The Intel Pentium processor with Intel dual-core technology delivers great desktop performance, low power enhancements, and multitasking for everyday computing.
The Pentium series has 1 MB of L2 Cache and only has a Front Side Bus of a maximum of 1066 MHz and goes as low as 533 MHz. The Pentium Dual Core series does not have Hyper-Threading and have only 2 stream processes. The Pentium series shares the same socket as the core 2 series which is LGA775.
3.) Intel Celeron processor
Intel Celeron processors provide a lowest cost computing solution for basic computing needs. It ranges in both single and dual cores and has a Front Side Bus (FSB) ranging from 266 MHz to 800 MHz. The Celeron offers a max of 512 kb of L2 Cache. Like the Pentium and Core 2 series it uses the LGA775 socket and does not have Hyper-Threading technology.
Notes:
Intel Turbo Boost Technology maximizes speed for demanding applications, dynamically accelerating performance to match your workload-more performance when you need it the most.
Intel Hyper-Threading Technology delivers two processing threads per physical core for a total of four threads for massive computational throughput. This 4-way multi-task processing allows each core of your processor to work on two tasks at the same time.
Intel HD Graphics provides superb visual performance for sharper images, richer color, and life-like video and audio.
Intel Smart Cache is a shared cache dynamically allocated to each processor core, based on workload. This efficient, optimized implementation increases the probability that each core can access data from the fast cache, significantly reducing latency to frequently used data and improving performance. Optimized for industry-leading multi-threaded games.
