I’m guessing you’ve never used an ARM Mac.

They don’t look all that fast on GeekBench (more on that in further down) but in real world usage they are incredibly fast. As in an entry level 13" school homework laptop will have performance on par with a high end gaming PC with a thousand watt PSU.

I’m able to play games with ghat 3k resolution with good settings while running on battery power and it lasts several hours on battery. Not a big battery either, it’s about half the size/weight of a typical gaming laptop battery. I’m also able to compile software nice and quickly, I can run docker with a dozen containers open at the same time without breaking a sweat (this is particularly impressive on the Mac version of Docker which uses virtual machines instead of running directly on the host), and stable diffusion generates images in about 20 seconds or so with typical generation settings.

The best thing though is I can do all of that on a tiny battery that lasts almost an entire day under heavy load and multiple days under normal load. I’ve calculated the average power draw with typical use is somewhere around 3 watts for the entire system including the screen. It’s hard to believe, especially considering how fast it is.

On the modest GeekBench score Apple ARM processors have - it’s critical to understand GeekBench is designed to test very short bursts and avoid thermal throttling. Intel’s recent i9 processors, with good cooling, will thermal throttle after about 12 seconds and GeekBench is designed to avoid hitting that number by doing much shorter bursts than that. Apple’s processors not only take far longer to thermal throttle, they also “throttle” by reducing performance to barely lower than full speed.

But even worse than that - one of the ways Apple achieves incredible battery life is they don’t run the processors at high clock rates for short bursts. The CPU starts slow and ramps up to full speed when you keep it under high load. So something quick, like loading a webpage, won’t run at full speed and therefore GeekBench also isn’t running at full speed either.

A third difference, and probably the biggest one, is Apple’s processor has very fast memory and also massive memory caches which are even faster. Again that often doesn’t show up on CPU benchmark because it’s not really measuring compute power. But real world software spends a massive amount of time just reading and writing to memory and those operations are fast on Apple’s ARM processors.

You really can’t trust the benchmarks when you’re comparing completely different processors. You need to try real world usage, and the real world usage difference is game changing.
