That "older baggage" takes up less than 5% of the chip. While I'm all for simplifying the platform, lets not act like it's a major step. It's not going to make much difference either size or speed wise, but it's just plain time to put 32 bit to rest.

- yvdriess 3y agoThere are other costs than silicon real estate. Those modes and microcode need to be validated, tested and add bloat to the boot software stack.
