The Pentium G620 belongs to the newer Sandy Bridge architecture while the Pentium E6700 is an older processor. Intel has tried to keep the Pentium brand name by launching deprecated Sandy Bridge desktop processors.
There are two important differences
1. The Pentium G620 has integrated memory controller while the E6700 does not has one. This increases the memory latency and degrades performance.
2. The Pentium G620 has integrated graphics while Pentium E6700 has no integrated graphics.
The Pentium G620 has better processor performance even when it is clocked lower than the E6700.

Pentium G620 Vs Pentium Dual-Core E6700 Benchmarking Comparison
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 Dual-Core E6700
The dual core Pentium E6700 is low cost ( $75) processor that competes in its price range with AMD’s dual core Athlon ii and Phenom ii clocked about the same. The Pentium E6700, does not come with integrated memory controller. Its FSB at 1066 MHz creates bottleneck in memory as well as south bridge communication. The main charm of this processors seems to be its low price. None of the Sandy Bridge processors launched ( even the entry level low clocked i3s) come in as low price range as this one.
