No (less) legacy (smaller chip die area, faster and easier decoder). Paying prime prices for TSMCs newest nodes, one node ahead of everyone else. Bigger (more expensive) caches. Faster memory interface.
Nothing magic.
But the deep integration with better margins and higher end product prices allows Apple to have more expensive CPUs than the competition.
- DeathArrow 2y ago>No (less) legacy (smaller chip die area, faster and easier decoder) What do you consider legacy? Can you point out how much it does affect die area and the instruction decoder? If I'd take a guess it's not more than maybe 2 or 3%.
- KingOfCoders 2y ago3% is 3% - IPC gains for Ryzen would not be 15% but 18%. But I do think the benefits are in a faster and easier decoder, and easier memory interfaces etc. Not a hardware engineer, from a software engineer dropping legacy code makes development of new features easier and more cost efficient, so I can concentrate on other things. But as I've said, I'm no hardware engineer.
- mkl 2y ago3% of die area is not the same as 3% of IPC.
- KingOfCoders 2y agoYou're right. I wasn't clear, I didn't mean IPC goes up by 3% with that change, I've used that as an example of how 3% can be significant.
