The Pentium G620 belongs to the newer Sandy Bridge architecture which gives it some inherent advantage over the Pentium E5700. The G620 has integrated memory controller with which it can communicate to the memory directly improving the memory transfer time.
The Pentium G620 also comes with an integrated memory controller – nothing great but still good enough for a video decode and display and entry level graphics. Do not expect it to perform for demanding games. The Pentium E5700 has no graphics.
The Pentium E5700 is, however, clocked higher at 3.0 GHz ( versus 2.60 GHz for the the G620), which ensures that pure processor performance of the E5700 is not too far behind the Pentium G629

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 awailable ( See G620T
Some more details of Pentium E5700
Intel’s Pentium E5700 is a dual core desktop processor with moderate performance. Some of its architectural shortcomings leads to inferior performance as compared to the Core i3 processors.
We strongly suggest that you take a look at the Sandy Bridge Architecture as Pentium G620 belongs to this architecture.
