No analysis of these bleeding edge personal computers is complete without some hard numbers regarding holes.

I estimate about 150 holes - each slightly larger than a dime - drilled into the front face of the Mac Pro. These holes are deceiving, though. The holes don’t penetrate all the way through the face; the grill is instead met by a slightly lower number of holes drilled into the back. Let’s split the difference and say that the Mac Pro has about 130 high performance holes.

The MacBook Pro takes a radically different posture of an estimated 3000 holes per side for a rough total of six to seven thousand low performance holes. (That’s just an eyeball estimate, I’m looking forward to actual geekbench numbers.) 

So the question for the eventual Apple Silicon desktop pro is, are we all in on tiny holes, or does the future hold a hybrid of fewer high performance holes mated with an array of low performance holes? Will the M2 MacBook Pro perhaps have one or two high performance holes, and will that necessitate an expansion of the notch? Only time and Ming Chi Kuo will tell.

Let us all hope that Apple will sell ARM motherboards that will fit into the 2019 Mac Pro, along with driver support for at least the 1st party  dGPU modules, HDD modules, Afterburner modules, etc. They will hopefully sell 1st party 64 and 128 GPU core MPX modules too, for all the customers who just need more GPU compute.

If the rumored half sized Apple Silicon Mac Pro starts at $2000, a full sized Mac Pro (2019 model) starts at $5000, and a Mac mini starts at $700, Apple will have a full headless desktop lineup spanning all the price tiers since 2006, just before the PPC to Intel transition. Even more so than back then even. That "half size Mac Pro" has to hit $2000 though.

Hope away. Not gonna happen. Sell Apple Silicon mother boards that the user can swap out in the current Intel Mac Pro? Hilarious. Ridiculous.

Apple says this supports up to 96kHz, and means users "can enjoy high-fidelity, full-resolution audio."

Soooo???? You're saying they therefore shouldn't have improved it all then?

Probably that you can't call something 'full resolution' if you yourself deliver a much higher resolution. 

The average human can detect sound in the 20Hz to 20 kHZ.  96kHz is way outside the range of human hearing.

96kHz is not upper frequency response - it is the encoding bite rate - higher = better resolution but 192kHz is more than necessary to do the job but that's audiophiles for you

Neither of you are right. It's not the maximum frequency that can be produced, nor is it the encoding bit rate. It's the sample rate. Completely different and entirely unrelated to the encoding bit rate. It's the number of times per second that the audio signal is sampled; sampled meaning a measurement or snapshot of the frequency at that exact moment is taken (or generated in the case of audio out).

Now where this does relate to human hearing's maximum frequency, is the fact that humans can't generally hear more than 20kHz. Sampling at double that rate means there will be no aliasing errors in the audio - where parts of the audio could be "missed" essentially, as the samples might fall on two sides of a frequency peak. This is known as the Nyquist rate. The sound between the samples is effectively interpolated (averaged), and of course the higher sample rates mean there's less averaging going on. Audiophiles claim they can hear this, but double blind tests have shown that almost no one can actually tell the difference. And the Nyquist rate says 44kHz is plenty high enough to accurately reconstruct a 20kHz signal, proving that high sample rates are pointless.

The bit rate is inversely related to how much of the original audio is thrown away, and how much the MP3/AAC/whatever decoder has to "guess" to reconstruct the audio.

Apple says this supports up to 96kHz, and means users "can enjoy high-fidelity, full-resolution audio."
