XQD has never caught on and there hasn't been a camera released that uses them since 2018 Whats up with photo/video people gatekeeping “serious” vs functional Your point might have some merit but SD will hold out for the next 5-8 years that purchasers of this machine will expect

Regardless of the potential merits of alternative storage formats, it's a good point that people who have needed an SD card reader since their removal have probably gone out and bought external ones by now. I'd expect the standalone units to generally be higher-quality than the ones that would be built in. That said, I'm glad to see Apple has finally realized some of the ways they've been alienating their customer ba…

That seems a bit weird to me. Many programs are hard to multithread but I'd expect that if any given program can make effective use of 8 threads it can probably keep scaling to 16 and 32. The hard part is getting from 1 to 2 and 2 to 4. So I'd expect that in most cases having more than 8 high performance cores doesn't make that much sense.

Amdahl's law can be formulated in the following way: S_\text{latency}(s) = \frac 1 {(1 - p) + \frac p s}

Why focus on the Geekbench test? I thought the industry standard for CPU testing was Cinebench and AIDA64.

I don’t know about AIDA64, but Geekbench tests a variety of more real world or at least more varied scenarios compared to cinebench which just does CPU rendering. You can see the full description here ( https://www.geekbench.com/doc/geekbench5-cpu-workloads.pdf ) but there’s compression, encryption, compiling, and several other tests.

Really would like to know more about the GPU and Ram. At 128 gpu cores vs the 8 in the M1 you talking 16 times the potential GPU power which could put it up there near the top of discrete GPU's.

Curious about this too. Anything more than 16 GPU cores seems like it'd too big to fit on die (share with CPU cores and everything else), so may need to be a discrete solution. Would Apple then make discrete GPU solutions using PCIe5? Makes sense for the Mac Pro given the edge cases for requiring multi-GPU solutions.

Consider the use cases. The Mac Pro is a desktop, always plugged in and used for the power. The M1 is on a laptop running on a battery where efficiency is more important to improve the battery life.

I wonder what % of high end users actually work on battery only. For me it's mostly a desktop that I move between home and office. And like maybe 2% of time batteries.
