Codenamed: Clarkdale (Westmere) Bus: Direct Media Interface replacing FSB( Front Side Bus) The Intel Core i3 3220-3240 models are dual-core, built on a 22 nanometer process. They have Hyperthreading, but do not have Turbo Boost Technology. Hyperthreading Turbo Boost They have built-in graphics processors. Clock speeds : 2.93 to 3.06 GHz. Cache : 2X256 KB L2 and 4MB L3
Continue… Hyper Threading It is a technology used by Intel to simulate more cores than actually exist on the processor. It also improves performance when using programs that make good use of multi- threading.
Continue… Turbo boost Turbo Boost is kind like a safe way to overclock your processor. It makes your computer go a lot faster when you need it Turbo Boost gives you extra speed when you need it. It’s on the i5 and i7, but the i7 is so powerful you really don’t need it. Turbo Boost enhances the speed of our computers.
Codenamed: Lynnfield (Nehalem), Clarkdale (Westmere) The Intel Core i5 3330-3570 models are quad-core, built on the 22 nanometer process (for better power efficiency). They have Turbo Boost technology, but no Hyperthreading. They have built-in graphics processors based on the HD Graphics 2500 and 4000 architectures.
Continue… Core i5 has a better processor, high performance, fast accessing speeds. Bus: Direct Media Interface Core i5 has two cores. 1. Dual Core (similar to Core i3) II. Quad Core (Much Closer to Core i7)
Continue… They offer the best Performance. They support Turbo Boost and Hyper Threading. Don’t have an Integrated Graphics Processor.
Continue… They have Quick Path Interconnect (QPI) which is faster than both DMI in Core i3/i5 and FSB. The Intel Core i7 has four processor cores inside of it.
Continue… This means that the i7 can run multiple programs at once more efficiently than the dual core. Also, the i7 is hyper threaded.
CORE I3 VS I5 VS I7 Performance: Besides being multi-core, Hyper Threading technology combined with the Turbo Boost makes i3, i5 and i7 to be computing power houses. For gaming: Core i7 processors win hands due to their phenomenal processing power.
Continue… Raw power: Even Core i5’s are good enough but if you want raw power then its good to go for i7. Core i7 is much faster due to the QPI (quick path interconnect), Hyper Threading and Turbo Boost.
