Could AI do a story that identifies the software that can utilize multiple CPU cores to enhance performance?  And the software that utilizes single cores/single threading that can’t benefit from multiple cores?  All the hype about multi core performance is meaningless if you don’t run software that is written to support multiple threads. 

"Multi-core" isn't just about splitting a single task to run across multiple cores there's also a need for smooth multitasking. The more cores you have the more a system can process at the same time; today's operating systems run hundreds of processes and thousands of threads in the background, so those extra cores come in handy.

And I would say that CPUs today are smart enough to know what task can be broken off into its own thread even if the app wasn't specifically designed for it. Even Apple's SoC's can take a task and determine which processor would be best to complete it; CPU, GPU, ANE, ISP, etc.

Apple is not going to release the next iMac with an M2… that SoC is now 16 months old. If they were going to do that, they would’ve done it months ago. The only reason the iMac has not been updated is because they were waiting for the M3. So, I predict we’ll see an M3 iMac, and a larger M3 Pro iMac.

The actual raw power of the CPU cores won’t see a huge increase, but the efficiency of the new 3nm process will allow Apple to pack more cores on the SoC without increasing power draw…

M3; 10 core CPU (6 p-cores + 4 e-cores), 14 core GPU, 12GB RAM
M3 Pro; 14 core CPU (10 p-cores + 4 e-cores), 24 core GPU 

“Scary Fast” will be relative to previous M1 iMac… upwards of a 40% increase in performance.

How many GPU cores can the ultra use effectively?

I guess more to the question if the rumour was true about a future Mseries having 2 ultrafusion interfaces one on the GPU edge and a new one more CPU. In the rumour this allowed for the extreme doubled ultra.  But with 2 interfaces they could fuse a Prefect Pro with a working GPU section to make a Max, 2 Prefect Pros or Maxs to make the ultra(s) and 4 Prefect Pros to make the extreme. 

How big would the Pro chiplet need to be with those interfaces for Apple to only make Pro Chiplet?

GPU cores should scale linear, if software is written properly. So if the M3 Pro has 24, the M3 Ultra would have 96 cores. and basically come close to other high end GPUs.

This article jumps around illogically, M2 or M3… and misses the initial point that it would be 16 months from M2 release to M3 vs 19 months from M1 release to M2.

The cadence isn't about keeping a distance to a previous version - it is about technology being available. 3nm is available to Apple and only Apple. No reason to wait.

Actually it was not only available to Apple. It was available to anyone who wanted it, The fact is, TSMC introduced a newer cheaper process for the first half of next year and the others who wanted 3nm decided to skip the first process, specifically Intel, in favor of the cheaper process. Apple is basically one of the few companies that could really afford this first process, so they are taking 100% of TSMc’s capacity to produce wafers. They have more than enough capacity to produce both the A17 Pro and the base M3. Apple will make up the cost in volume, where others simply can’t.

do they not understand what carbon neutral means? It means you do something to offset the carbon emissions you produce. You effectively “wipe out” the carbon you put into the atmosphere.
