Yeah if http://www.notebookcheck.net/Mobile-Processors-Benchmarklist... is to be trusted, it's indeed quite a bit slower.

What a bummer, I was seriously hoping to replace my 2012 MBA, but now... apparently the Core M processor will unfortunately be a good deal slower, than the one used 3 years ago. Which means I'll probably have to go with a Windows based laptop or wait for the MBP update.

Just fyi: Notebook Check is very reliable. They're arguably the leading laptop review site and have been for quite a few years. They're located in Austria and are ad funded, but I've always found their editorials and reviews to be pretty darn good.

Yeah, I'm coming from a 2011 MBA with an i7 2677M.

The Core M *71 isn't that far off--3DMark is notably lower, but most others are pretty close.

But what concerns me is that reviews of other systems with the chip mention that it throttles itself pretty aggressively when hot. I have no idea how much that would or wouldn't hit these benchmarks. This might be best-case performance on a cool day, for the first 30 minutes.
