Ooooh good point - haven't actually heard of newest NVME stuff before.

The M1/M2 apple hardware specifically seems to be around an order of magnitude from what I've seen (ddr4x 60-70gb/sec vs 7gb/sec for the NVME or thereabouts).

The obvious observation here is that the fab yields for high memory apple silicone must not be all that great, which is why they're mostly shipping 8 and 16gb versions.

You just switched from DDR3, to the latest (few laptops offering that) DDR4x. And even then it's barely one order of magnitude.

You were wrong, it's ok...welcome to the SSD future :-)

"only" an order of magnitude.

Never mind comparing bleeding edge NVMe with (by now) decade-old DDR3, while the current bleeding edge DDR5 is now trickling out at 100GB/s+ pretty easily.

Never mind DDR memory latencies of ~50ns, vs NVMe at 50uS+.

Just because the user doesn't notice GUI problems doesn't mean it's not going to be a catastrophic bottleneck in any memory-intensive application.
