    Hi.

    I was reading about processors, but I’m a bit confused. I read that Core M processors are less powerful than full Core i processors because they are designed for mobile devices while the full Core i’s were designed for laptops and desktops, so I initially took that as the Air's Core i5 being more powerful than the MacBook's Core M.

    However, the 2017 MacBook Air’s Core i5 is from the Broadwell generation while the 2017 MacBook’s Core M3 is from Kabby Lake.

    From what I understand, Kabby Lake chips are supposed to be faster and more efficient than those from older microarchitectures, so I guess that should make the MacBook better than the Air? Then again, Core M processors are designed for mobile or ultra-thin devices which typically have less processing power, I think?

    I wonder which one is actually better, especially when multitasking or using more resource-demanding programs? Will there be a significant difference between the two?

    The core i5 is much better.

    Thank you for taking the time to respond.

    Can you please provide additional details as to why you think so? I'm not questioning the answer to be clear. I'm just genuinely curious because I've been comparing benchmark results and they're returning different results so I'm getting totally confused.

    The clock speed is a primary indicator. The Kaby Lake M3 runs at 2.20 GHz, compared to the i5's 2.90 GHz. This speed would make a good difference in tasks. This benchmark will help explain further http://www.cpu-monkey.com/en/compare_cpu-intel_core_m3_7y30-657-vs-intel_core_i5_5350u-467

    I'd take the i5 as well, the M3 is more specifically designed to be low power as you can tell by the base clock speed and 4.5w TDP. Even with the IPC improvements of Kaby the clock speed difference will be better on the i5.
