So, today MR reported on references to unreleased chips on Apple's Tatsu Signing Server. This appears to actually have been discovered by MR user LeoI07 as described in this post, then later more ApChipIDs were discovered by twitter user _orangera1n running LeoI07's script.

Unsurprisingly, MR completely missed the only interesting part of the discovery. Here's a list of the ApChipIDs, their corresponding descriptions from this page on The Apple Wiki, and pretty obvious inferences:

Code:
0x6000    # M1 Pro
0x6001    # M1 Max
0x6002    # M1 Ultra

0x6020    # M2 Pro
0x6021    # M2 Max
0x6022    # M2 Ultra

0x6030    # M3 Pro *
0x6031    # M3 Max *
0x6032    # M3 Ultra *
0x6033    # <========== MYSTERY
0x6034    # <========== MYSTERY

0x6040    # M4 Pro *
0x6041    # M4 Max *
0x6042    # M4 Ultra *

0x6050    # M5 Pro *
0x6051    # M5 Max *
0x6052    # M5 Ultra *

0x8015    # A11 Bionic
0x8020    # A12 Bionic
0x8027    # A12X and A12Z Bionic
0x8030    # A13 Bionic

0x8101    # A14 Bionic
0x8103    # M1

0x8110    # A15 Bionic
0x8112    # M2

0x8120    # A16 Bionic
0x8122    # M3 *

0x8130    # A17 *
0x8132    # M4 *

0x8140    # A18 *
0x8142    # M5 *

0x8150    # A19 *

* inferred

My first thought was, "M3 Extreme and M3... Extremer?" Then I thought that maybe they're something related to the Vision Pro, but the R1 is allegedly 0x6500 (see link above). Going back to the "Extreme" chips, perhaps every third generation will include higher-powered chips? NB that I'm specifically not necessarily talking about 4 or 8 die packages.

So what do you think?

Interesting … possible? But the rumor seemed to be pretty emphatic about no Extreme chip as in no special chip for the Mac Pro and there’s two chips to explain, not one. And they only show up for the M3. That’s definitely a head scratcher if it’s denoting something real.

Like back in the day I might’ve agreed that these are special iMac Pro and Mac Pro processors updated every three generations with only ultra variants of each getting updated every generation. But that just doesn’t feel super likely?

Yeah, I’d also like to verify their findings myself, but I haven’t found the script used and haven’t had time to poke around that server yet. From what I’ve seen, they do seem to be legit “security analysts” though.

Edit: Okay, I found the (rather rudimentary) first version of the script. I’m going to rewrite it to be a bit more discreet, add some other functionality, and give that a shot tomorrow.

Also, there’s a lot of info on their discord server, particularly this thread. And, apparently, the R1 being 0x6500 is from this post on twitter.

Before I turn in, just in case that server might be slated to be sealed up pronto, I ran a slightly modified version and indeed it checks out.

㎥ cube you mean

  • 64-core CPU (48P/16E)
  • 448-core GPU (w/hardware ray-tracing)
  • 128-core Neural Engine
  • 960GB ECC LPDDR5X RAM
  • 2.16TB/s UMA bandwidth
  • 32TB SSD (4 @ 8TB NAND blades)

Thing is, apple /could/ surely build that if they were interested in that segment of the market. 2TB/s memory bandwidth and ~1TB of Ram are not out of the question in 2023 for a very high end machine.

To be succeeded by the M4 "Klein Bottle" Mac, in which Apple extends the hardware into a hidden 4th dimension, giving new meaning to the word "proprietary".
iFixit, unable to access the extra dimension, assigns the M4 a repairability score of .
