Intel Pentium G620 vs Core i3-2120

Intel’s Pentium G620 belongs to the Sandy Bridge group of processors – the same architecture that drives the Core i3-2120. Both are dual core desktop processors and share few decent improvements in the architecture including integrated graphics controller and an Integrated Memory Controller.

The Pentium G620 however is a deprecated version with some features reduced. Most important of these is the absence of Hyperthreading. It is also clocked slower than the Core i3-3120 ( – 2.60 GHz Vs 3.30 GHz). The overall result is a reasonable drop in the performance.

The Pentium G620 is still good for entry level desktop computing but if you need better performance, go for Core i3-2120 ( or may be higher core i5 or core i7).

Some more details of Pentium G620

e Pentium G820 is a stripped down version of the Sandy Bridge processor (Hyperthreading has been removed from this processor). It is intended for the entry level to moderate performance desktop processing. G8620T is a low cost processor that should be delight to low cost system builder and will take on the AMD’s low cost Athlon ii and Phenom ii dual, triple and quad core processors. The Integrated graphics runs at 850 MHz and can ramp to 1.1 GHz based upon demand. A low power variation of this processor is available ( See G620T)

Some more details of Core i3-2120

The Core i3-2120 is the second generation Intel Core i3 processor ( Also called Sandy Bridge Processor) improving significantly upon the architecture that evolved from Arrandale. Although turbo boost is not available in the core i3-2120 ( The newer turbo 2.0 technology, that increases the time for which processor can be in the boosted state, is available only on the second generation core i5 and i7 processors), the processor still shows significant performance improvement over similarly clocked 1st generation core i3 processor. The more significant improvement has been in the area of integrated graphics unit.
