Intel Pentium Dual-Core G2120
Xeon E5-2680v2
An entry-level CPU in 2012/2013 that floats just a little bit under the Core i3: depending on the model you have differences in clock-frequency (although you can have 3.3GHz in both Core i3 and Pentium Dual-Core for instance). The only 'big' difference is that the Pentium Dual-Core doesn't feature Hyper-Threading.
Another difference is the somewhat weird naming convention. Intel uses G2020 for 2.9GHz and G2030 for 3GHz. Logic dictates that the 3.1GHz part would be dubbed G2040, however, Intel decided to name is G2120. As far as I can see the G21xx and the G20xx have identical specs as far as integrated graphics, memory support and features goes.
To make things worse: the G2120 and 2120T have the same numerical name, yet the T stands for power optimized (or Thermal optimized?) processor which makes it less power hungry. However, the CPU runs 400MHz slower than the G2120 'vanilla' version. Why use the same numerical identification for a slower product?
