On @atpfm 431 we discussed the latest ARM-based Mac Pro rumors. Keeping in mind that Apple's marketing diagram of the M1 SoC does NOT accurately represent the floor plan of the chip, I nevertheless thought it would be fun to extrapolate from it to the rumored Mac Pro power plant.

Even if the rumors are true, it's not clear at all if this would all be on a single die or even a single package. It could be 3nm instead of 5 nm. The CPU/GPU cores could be different. And who knows where the RAM would be? But assuming the same cores, one die, and 5nm…it's big.

Here’s the @atpfm episode, BTW: atp.fm/431 Use your chapter-marker-savvy podcast app (like @OvercastFM!) to jump to the chip rumors.

Once again noting that Apple’s marketing diagrams do NOT accurately represent the floor plan of its chips, here is a less fanciful interpretation of the Pro Mac SoC rumors.

Presenting Jade-C: The building block for Pro Mac SoCs. (M1 included for scale.)

Jade C-Die: The building block for Pro Mac SoCs
• 8 high-perf cores
• 2 high-efficiency cores
• 32 GPU cores

Jade C-Chop: Jade-C minus 16 GPU cores
Jade 2C-Die: Two Jade C chips in a package
Jade 4C-Die: Four Jade C chips in a package
