Pretty impressive results.
Looking through the Cinebench R23 charts, it's pretty obvious that the 11th gen Intel i7-1185G7 is the best CPU Intel has ever released, by a good margin, and it
much more directly competes against the M1 than Intel's desktop chip--it's got the same number of performance cores, and with a 28W TDP (14W "down-TDP" for thermally constrained form factors) it's targeting roughly the same thermal envelope when under heavy load. Basically, it's targeted to about the same classes of computer as the M1.
It's actually turning in very slightly better single-core results in Cinebench than the M1, which is significantly different from some other benchmark results. It's still, however, a solid 15% slower than the M1, which given Intel's decades in the business versus this being Apple's first "computer grade" mobile chip is still a very impressive feat.
The other chip to be comparing to is, I believe, the Ryzen 7 4700U, which has been out a bit longer and has twice as many cores with around the same TDP (25W). It falls
way behind both CPUs in single-core, so isn't going to perform nearly as well in day-to-day tasks, but it does outperform the Intel part on multi-core while coming in a decent margin behind the M1.
Much less flattering for Intel are the results of the 10th gen 6-core i7 series with a bigger-laptop 45W TDP, which have only been on the market for a few months longer than the i7-1185, and are right in line with the M1 for performance.
Cinebench is a more intensive multi-thread test than Geekbench 5, testing performance over a longer period of time, and it can provide a clearer overview of how a machine will work in the real world.
I take some issue with this "real world" claim. Yes, Geekbench is a very synthetic benchmark. And yes, Cinebench is a real-world task, albeit a very specific one. And yes, if you're doing heavy crunching, Cinebench is going to give you a much better idea of what the CPU can do within its thermal envelope (I'm assuming the Air will turn in measurably worse results than the Pro since it's limited to 10W).
...but a
lot of "real world" computing doesn't involve sustained throughput, so such benchmarks may actually undersell the real-world "feel" of something thermally limited like the Air with a chip that can run very fast for short periods of time.
Reasoning: If I'm doing "everyday user" tasks, the CPU isn't sitting there maxed out for the vast majority of the time I'm using the computer. It will do a bunch of work loading a web app or rendering a complex page, then sit there quietly for a while. It'll to a bunch of work processing a image for a couple of seconds, then sit there quietly for the next minute while I touch up small parts of the photo. All modern CPUs can crank a single core way up in output to work with workloads like this, but if--and this is purely hypothetical--the M1 is better at doing that for a few seconds at a time in the tight thermal envelope of a MBA than an under clocked/thermally limited i7-1185G7, then it's going to behave much
better in real world performance than sustained benchmarks will indicate.
This is one of the reasons that iPhones are demonstrably so fast--they can't sustain huge CPU throughput for more than a few seconds due to the thermal constraints, but many everyday tasks only require a few seconds of huge throughput. So while it won't render video as effectively as a laptop with a fan, it's faster--and
feels faster--in a lot of everyday tasks.
It's also akin to the situation with SSDs; many M.2 SSDs can't sustain huge throughput for long periods of time due to thermal limitations, but they don't need to under many cases, since what they're generally tasked with is short flurries of heavy activity followed by long periods of idle.
All of that is purely hypothetical at this point, and honestly is kind of hard to benchmark accurately even given ample time and tools, but it's worth remembering that while number-crunching through heavy sustained workloads are an important thing for some pro users, for a lot of use cases, it's the "burst-processing" capability that makes the biggest difference.
