Released January, 2013

Reasons to buy the Intel Pentium G2020

	Slightly more l2 cache 1 MB		Significantly better performance per dollar 7.39 pt/$
	More l2 cache per core 0.5 MB/core		Marginally newer Jan, 2013

older Released September, 2012

Reasons to buy the Core i3 3220

	Is hyperthreaded Yes		Higher clock speed 3.3 GHz
	More threads 4		Better PassMark (Single core) score 1,764

The Core i3-3220 doesn't benefit from Intel's Turbo Boost technology at all, but instead relies on an architecture able to execute more instructions per cycle than AMD.

You might be right but most of the time depends on the PSU too....

Ricky (04:41 PM, August 30, 2013)

Some of the modern games will reveal some bottlenecks if you have a fairly cheap CPU and a really good GPU.

Serialmania (02:44 AM, July 30, 2013)

G2020 is one of the underrated cpu for this year. People fail to realized that graphic cards matter 80% for gaming. Lousy graphic card means bad gaming performance. I'm pretty sure you can play some of the latest games on max settings with this cheap cpu as long as you have good graphic cards..... I can even play the original Crysis and Crysis 2 on my old core 2 duo cpu on some high settings.

Thanks for bringing this to our attention. There was an error in the overall performance calculation. This has now been corrected.

Pete (01:58 PM, July 17, 2013)

Your figures for (relative) performance per dollar and per watt appear incorrect - think about it! How is it possible for the G2020 to have a higher performance per watt than the i3 considering they use the same power and the i3 clearly outperforms the other? Methinks you have mixed something up. Similarly the perf per dollar cannot be more than 2x the i3 model, at least based on the quoted Amazon prices.
