Looks to me like the M1 has excelled with your workflow.
A superthin fanless 20+ hour battery laptop is as fast as something uses 10-20x the power.
-> impressive indeed
You are comparing a top of the line desktop with combined component power consumption of over 200W to a low-power silicon with power consumption of 25W if you push it very hard. I’d say that reducing the power consumption by 8 times while improving the performance by 50% is not bad at all for 8 years of progress.
I will address your comments by first quoting myself:
M1 Mac Mini.
It is a really great computer, and probably the best value of any Mac ever.
I love my M1 Mac Mini, and I really think it is the best value of any Mac. The power that it provides for the price is amazing.
I am just responding to the OP by saying that while the M1 Macs have been impressive for the value, I am disappointed in the performance when compared to my much older Macs. I was just expecting more of an improvement.
Yes, my iMac is a top of the line, BTO Mac, and it cost 3 times the price of my M1 Mac mini, but it is still going on 9 years old, with 9 year old thermal paste, 9 years of dust built up inside, and it is able to keep up with a modern device.
I have two Mid 2011 27" iMacs, one has the 2nd gen i7 with the top of the line GPU, 32GB RAM, so an "apples to apples" comparison to my Late 2012 iMac, and the Late 2012 is very noticeable faster than the Mid 2011. A friend is using the Mid 2011 with a i7, so I cannot do the exact encoding test that I mentioned earlier, but back when using it to encode, the Late 2012 was probably about 30% faster on average.
The performance difference was very noticeable between the two iMacs with just one year difference in age.
This might be more of a problem with Macs in the past 9 years, that there hasn't been much improvements in performance like there used to be. Maybe this is due to Intel, or the industry in general, but we just don't see the performance gains that we once got from one year to the next.
I originally planned on replacing my main Mac (Late 2012 iMac) after about 3 years, but after that time, the performance of the Late 2012 iMac was still really good and not worth the investment of a new Mac.
The old year-to-year performance increases pretty much went away since I purchased my Late 2012 iMac.
Maybe your expectations were a little too high for real use and need to be adjusted?
Yes, this was pretty much the case.
I am not saying that the M1 isn't impressive with what it does especially for the cost, or how much power it uses, but I was expecting a little more considering my much older Mac can still hang with the brand new M1.
Intel hasn't improved that much over the past 10 years.
I think this is true, and probably plays a part in my disappointment mentioned above.
I’d say that reducing the power consumption by 8 times while improving the performance by 50% is not bad at all for 8 years of progress.
I am not saying that this bad at all, in fact very impressive, but I can be both impressed by the power-per-watt and disappointed in the overall performance compared to my older Macs.
A superthin fanless 20+ hour battery laptop is as fast as something uses 10-20x the power.
Also, my comparison was with the M1 Mac Mini, not the MBA. I suspect that the performance difference between the Late 2012 iMac and M1 MBA would be even less.
But, considering the MBA is passively cooled, the performance is pretty amazing on it.
