2011 versus new Air - Processor speed?

[deepakvrao]

I have a 2011 13" and it says it has a 1.7GHz Intel Core i5,a and the new one says it has a 1.3GHz dual-core Intel Core i5.

So is it a lower speed because it is a dual core? Confused about this.

Both are dual-core but haswell has a better architecture (as far as i know). Therefore the speed of 1.7GHz (ivy bridge) and 1.3 Ghz (Haswell) are similar.

Ghz is only really a useful comparison between different processors of the same generation and architecture.

1.3GHz (Haswell) is only slower than 1.7GHz (Haswell). Different generations and architecture, you can't do math and get a straight comparison.

What's more, the new CPU can get a turbo boost to 2.6GHz when needed, so it's definitely going to be faster than your model. It's clocked at 1.3GHz for normal usage to save battery life.

From a marketing perspective it's interesting that Intel would continue the i5 and i7 designations across generations, knowing full well that consumers may get confused.

Stop reading the marketing ads man, even a 2010 CORE DUO (duo get it?) is a 2-cores.

Just read the review benchmarks.

From 2011 to 2012, there was a 15-20% improvement over all.

I let you read the 2012 to 2013 reviews.
