I wonder if this will become the norm for all CPU manufacturers at some point.

If they put 64Gb directly next to a high end CPU and that made it 10% faster all around i suspect it would be a pretty popular choice despite the lack of upgradability.

I think for the most part upgrading RAM (capacity-wise) has been pretty stable (for my uses at least - programming and games). I've been on 16gb since...well as long as I can remember.

Every time I upgrade I'm jumping from DDR2 to 3 to 4 and probably soon 5. So its not like I keep the sticks anyway. Even when I stay on DDR4 I have to upgrade because the speed of the RAM is too slow to feed the processor. Its unfortunately rare for me to not have to buy RAM with a new CPU.

What about ECC?

As usual, the uncrippled "workstation" version will have ECC and the crippled "consumer" version won't.

I mean, ECC is going to mean lower yields from the fab and a higher TDP. Will it be worth it?

I don't see why that would be the case.

Because it’s half the density of non-ECC so bigger wafers, and runs at a higher voltage?

DDR4 ECC needs just 1 parity chip for 8 chip, not half. Of course it consumes a bit more power to calculate checksum. IMO it worth for every computing.
