Does the i7 run hotter than the m3 and how much better is it in the 2017 model MacBook?

I have the m3 and don’t feel like it’s slow at all. I can’t omagine it being snappier tbh.
I was just curious about the i5 and i7.
Wouldn’t be worth the speed increase for my usage if it runs hotter and has lower battery
Yeah I mean if someone told me I had the i7 I’d believe them bc my computer just snappy and fast.
If I used more intensive stuff I’m guessing that’s where I’d see the slow down.

As you can see, there is only about a 5-7% difference between the two. In some other bursty benchmarks, the variance can be as much as about 15%, but that's still not too much.

I'm so lost. What is m3 wood vs m3 granite? The one I'm using is space grey
And it seems like the m3 outperforms the i5? The granite one?
It's explained in the thread.
I tested the m3 on two different surfaces. Wood was on a wood table (insulator). Granite was on a granite counter (heat sink). On a regular wood table, the m3 does slightly worse than an i5, but the m3 on granite does slightly better than that same i5 score.
Ironically though, in this early Geekbench 5 chart, the i7 actually does worse:
https://browser.geekbench.com/mac-benchmarks
macbook 12” i7 on my machine gave a single core score of 851, and multi core score of 1751 on Geekbench 5, with the multi core score being higher than the m3 and i5 scores on that chart. I wonder if whoever submitted the one on that list had theirs cpu already under heavy throttle.
I decided to look up the highest multi-core scores for each model. Here are those multi-core scores, with their accompanying single-core scores.
i7-7Y75: 867/1889 (22 scores)
i5-7Y54: 786/1735 (28 scores)
m3-7Y32: 806/1645 (73 scores)
According to this sample:
i5 is 5.5% faster than m3
i7 is 14.8% faster than m3
i7 is 8.9% faster than i5
While I have the i7 the differences day-to-day are really small over the m3. 20% higher turbo, 10% or so higher base, and around 10-20% higher graphics max frequency. The 14.8% number seems about right. Don't know if the higher storage at 512GB is any faster than the lesser options.
I had an m3 16gb and now I have an i7 16gb... most of the time I feel that the m3 was faster because if you're doing any kind of work on the i7 that will make use of the processor for longer than like 30 seconds at a time - it will heat up and then throttle down slower than the m3. I regret switching.
I could possibly see this if you were doing transcoding or some other work that pegs the CPU at 100% for an extended period. But then a MacBook probably isn't the best solution here as it has no active cooling...
