The Pentium G2120 belongs to the newer Ivy Bridge series that brings 10% performance clock to clock improvement over the earlier Sandy Bridge. The Pentium G860 belong to the Sandy bridge.
The G2120 is clocked 100 MHz higher ( 3.1 GHz Vs 3.0 GHz), which makes it theoretically 3% better. This along with the 10% improvement due to Ivy Bridge architecture makes it about 13% faster.
The G2120 also comes with a better integrated graphics.

Some more details of Pentium G2120
The Pentium G2120 is an Ivy Bridge desktop processor, which is great for low cost entry to mid level computing. It does not come with Hyperthreading support, which makes it shed 10% CPU performance compared to the same clock, Hyperthread enabled Core i3 processors. When compared to the Sandy Bridge Pentiums, it comes with 10% clock to clock improvement and a a better graphics – HD Graphics 2500.
Some more details of Pentium G860
G860 is fastest pentium branded Sandy Bridge desktop processor. It is also possibly the last in the Pentium Brand series in the Sandy Bridge before Ivy Bridge launches. The Pentium G860 does not support Hyperthreading and also does not support Quick Sync – two important differences with the Core i3 Sandy Bridge processors. At 3.00 GHz, this dual core processor is still fast enough for most of your tasks. Pentium G860 can also be used for low cost gaming when paired with an external graphics card. The integrated graphics ( HD Graphics 2000 ) is good for displays – but not great for gaming.
