Whenever I use an older laptop I have that is on intel i7, 8th gen, these tasks are much much slower. I think it really depends on your workload.
Code compilation, hashing, rendering were all markedly faster though. That old PC became a perfectly serviceable hand me down after 5 years of service, and I hope to get another 5 out of this rig. Pretty cool that we're seeing longevity and some progress at the same time.
My work laptop is an M1 Max and personal laptop an ancient i5 Macbook. I had it upstairs recently and thought I'd do a little coding but gave up after a single `brew install whatever` was still going after 20 minutes and I lost my motivation...
The trouble is that Intel's rollout of the future has been shambolic at best. Potentially revolutionary extensions such as TSX and SGX failed. It is still too early to require AVX-512 which could speed up and reduce power consumption of your web browser since many of Intel's "latest and greatest" client CPUs don't support it. (Don't buy the false claim that AVX-512 is a power pig: sure it will consume a lot of power running at full clock because it is doing a lot of work... AVX-512 helps "atom class" processors quite a bit because it avoids instruction decoding which Intel is bad at.)
It's not clear that Microsoft's new line in the sand is going to buy them very much extra functionality for Windows.
Isn't that also the #1 reason not to upgrade? In other words, is Windows 11 compelling yet? As of now, mostly I just hear complaints, and ocassionally tidbits about better scheduling for newer chips with multiple core types (which is compelling, but only if you upgraded)
*Good lord, has it been 3 years already?
I had a 1271v3 in my son's PC until the motherboard died earlier this year and it was still quite beefy.
There have been a lot of 10%'s in the meantime, though...
