D. Griffin Jones, writing about yesterday’s news:
Apple decided to start caring about the Mac Pro again at the worst possible time. The Intel Mac Pro, while excellent, arrived just six months before the announcement that the Mac would transition to Apple silicon. After which, the Mac Pro didn’t offer any better performance than the Mac Studio. Just the card slots — which you couldn’t put a GPU in.
Due to Apple silicon’s all-in-one architecture, the Ultra-tier chip pushes the limits of what Apple can fabricate at a reasonable price. The bigger the chip is on the die, the lower the yield of good chips will be made, raising the cost further.
