So 10-20% increase in CPU on average over four years? At the same time the A11 (2017) to 2019 (A13) doubled in multicore score and we have the A14 just around the corner...Puts things into perspective.
AS. Behold the Titan.
Context. No observer can look at Intel or AMD for the best part of the last ten years and be anything but bemused by the evolutionary state of progress. I don't recall anything too dramatic. After the initial transition of PPC to Intel, things slowed. Intel were happy to sit on quad cores and milk them until AMD got off the canvas and chipletted them at much more affordable prices. In graphics? Nividia is out on the Mac. And 'last year, mid-range' performance is in. Both of these are inadequate for the Mac platform. 1st rate prices to be 2nd rate tech' citizens spanked by PC Gamer's for 'Macs that are crap at gaming.' We hath seen the light too late. As the PCs once again...go on an upward curve of GPU tech' which may never see the light of day in conventional terms on any Mac. Ampere. RDNA2? maybe on the iMac Pro or Mac Pro.
But I think it's a bit of a thing when you pay £3400 and you can't get the latest gpu tech'. Still. AMD don't have it to give right now. And they haven't had a high end offering in years. They haven't got it to give right now. November? Most were bored of waiting. But maybe they wouldn't have been bored of waiting had Apple done this iMac refresh last fall...when the gpu had been out for half a year by then. Or even offered it as a BTO option.
Grumbles aside. This legacy iMac is a worthy upgrade in historical iMac terms. As we can only compare to what was...and not what we think it should be (RDNA2 BTO which just isn't out. Blame AMD for that one.)
This dependency on partners who don't deliver performance or efficiency of power is over. Apple have finally had enough and now the Mac has joined the 'A' for Apple Family series of chips. With all of the destiny controlling power that brings. We would do well not to underestimate them and the computing experience that will bring. I await with intrigue.
The 'A' was, initially, coming from a place of humility and low hanging fruit with the intial iPhone and iPad releases. Even so...the gains from 2017 to 2019 are quite dramatic. As Apple created the A'x' variant, the performance gains ballooned from iPhone to iPad. Though these 'dramatic' gains have slowed down in some areas...the focus on other areas like A.i and machine learning...have been eye popping. And I have no doubt the jump from A12z to A14x will be eye watering for the opposition with the A14x poised to give the consumer Intel chips a right duffing up...
Ergo...what 'ballooning' of performance may we get from the unshackled AS?
Intel painted themselves into a corner. Greed. Hubris. Poor strategy based upon both blinded them.
I expect the single core AS to breeze past the static thermal stagnation of Intel.
The multi-core to blitz them.
And the gpu score to decimate them.
...and specific A.I acelerated user workloads...? Off the charts. Tough to replicate elsewhere with generic, monolithic brute force.
All without the need for a Nuclear Reactor to cool it...or risking meltdown or increasingly agonising cooling solutions which all hinder design progress.
