Intel Pentium G645  vs G2020 

Budget-minded desktop users need a reasonably priced processor which is capable of providing decent performance, while still easy on the wallet. Here are two CPUs which fit the bill: the Intel Pentium G645 versus the Intel Pentium G2020. Let’s see which one offers the better overall value.

The G645 and the G2020 are part of the Pentium Brand, but they’re one generation apart. They even share most of the basic essentials: Dual cores clocked at 2.9 GHz with 3 MB cache. The main difference is that the G2020 is newer by 4 months, and is part of the more recent Ivy Bridge architecture. This results to a smaller manufacturing process of 22nms (versus 32nms), which in effectively contributes to a lower TDP of 55W (versus 65W) for the G2020. How do these specifications translate in terms of real world performance.

Unsurprisingly, the newer architecture resulted to better performance for the G2020: it acquired 7% better scores in the PassMark test and 5% in the Single Core benchmark. If you take into consideration the fact that they’re within the same price range (give or take $5), we clearly recommend the Intel Pentium G2020 for its higher performance per dollar ratio as a better value over the Intel Pentium G645.
