  • M2 Pro Mac mini vs Mac Pro - compared

    blastdoor said:
    Good comments discussion of GPU performance. 

    In order for the Mac Pro to compete with 'pro' level Windows/Linux systems using high-end discrete GPUs, I wonder if Apple needs to either (1) continue to include high-end discrete GPUs in the Mac Pro (which kind of runs contrary to Apple's strongly expressed preference for sharing memory between CPU and GPU cores, but perhaps so be it) or (2) reconfigure Apple Silicon so that CPU and GPU cores sit on different pieces of silicon and are linked together via 'UltraFusion', thereby perhaps improving chip yields since CPU and GPU cores could be on separate cores. 

    I'm inclined to think that option 2 is more appealing technically, but I'm not sure about the business/economics side. If Apple puts CPU and GPU on different dies linked by UltraFusion (or whatever they want to call their 'glue'), they would likely need to do that across more product lines than just the Mac Pro. Maybe only integrate CPU and GPU on a single piece of silicon for the generic M#, but for Pro, Max, Ultra, etc, put CPU and GPU on different dies linked. That would allow independent scaling of CPU and GPU power to better target the needs of users who either need more CPU or more GPU (or both). 

    I can see no technical reason Apple can't have both a powerful on-chip set of GPUs as well as supporting discrete PCIe GPU boards for people who need it.  I've been running an AMD RX 6900 XT graphics card in a Thunderbolt 3-based eGPU enclosure made by Sonnettech, and getting similar GB 5 metal results to the current Mac Pro.  This is with a 5-year-old iMac Pro.

  • M2 Pro Mac mini vs Mac Pro - compared

    The 2023(?) ASi "Mac Pro" must either be able to reach the 166,946 GB5 GPU results either with on-chip GPU cores or by a discrete graphics card like the existing Intel Mac Pro, otherwise, why bother to even release it?

  • M2 Pro & Max GPUs are fast -- but not faster than M1 Ultra

    This is what I'm getting with my 5 year old iMac Pro with an eGPU. If and until I can match this with a Mac Studio (or maybe a Pro,) I don't think I'll be upgrading.  Of course, as others have pointed out, they could certainly port the Intel drivers to ASi and allow eGPUs.

  • M2 Pro & Max GPUs are fast -- but not faster than M1 Ultra

    If I did the math right, the M2 Max over the M1 Max was 47.5% higher on "Metal."  Hypothesizing equal improvements, we may get 139,500 out of the M2 Ultra in the Studio (whenever Apple decides to release it.) That's ALMOST as fast as I'm getting with my AMD 6900XT eGPU on my 2017 iMac Pro. With all of this said, I can't imagine Apple releasing a Mac Pro (with any chip!) that can't meet the "Metal" result already posted by the Intel Mac Pro:  166946.

  • First M2 Pro benchmarks prove big improvement over M1 Max

    How about the benchmark(s) for the M2 Max MBP.? That may be a more fair comparison against the M1 Max.
