Released January, 2013
  • 2.9 GHz
  • Dual core
6.7 Out of 10

Intel Pentium G2020 is a processor of the Ivy Bridge series with two cores that are clocked at 2.9GHz. It also includes an integrated Intel HD Graphics card with a base frequency of 650MHz. This processor offers an impressively low power input, while sustaining a power output values that are similar to 3GHz processors of the Sandy Bridge generation. The G2020 is also incredibly cheap, for the stellar performance it offers, and is capable of sustaining up to three monitors and playing newer generation games with no lag, making it perfect for enthusiast gamers who are looking for an inexpensive, but fast, processor.
