However on desktop where power usage isn't an issue, Intel 12th gen performance has pulled ahead of AMD. Theoretically even on laptops too but I suspect they have the common problem of powerful Intel cpus in laptops where they cooling just can't hack it and they throttle to make it worthless getting top end Intel. So I believe AMD is still better on laptops presently.
… right now I say to wait until the end of 2022 for a build. Let Zen 4 and Raptor Lake come out. Then realize Zen 5 and Comet Lake are likely another very real step above that the following year, though at least you’ll be able to take your new PSU, memory and GPU along with.
Never mind the reality that Apple is just getting started.
Granted, you can’t wait forever. I did a build last year, and now get to see how things shake out as all the new stuff comes available over the next few years.
Also, the AM4 socket is at the end of its life. Intel’s LGA 1700 is expected to be used for two more CPU generations, so there’s an upgrade path.
Do you have any sources? I was unable to find any info on Meteor Lake and board compatibility.
That said, AM4 is a dead end socket, so building right now is a coin toss between the 12900k and the 5950x as far as price and performance. I'm not sure the 13900k is going to be much of an upgrade.
I just bought a 12400 mostly because it was 15% cheaper than the 5600x and it comes with an iGPU. You're right that it's unclear whether 13th or 14th gen will be an upgrade or possible, respectively.
And I felt (perhaps incorrectly) that you get more horsepower for your buck with AMD.
Of course, M1 is pretty cool too.
