It looks like it's 60% faster, I'm guessing this is due to more cores and faster memory. Think I'll wait a few more years before upgrading then.

Meanwhile my 7 year old i7 3770k is still almost as good as the new proccesors with 3.4 base and 4 boost. How come processors have had such marginal gains since 2012?
