This is absolutely a factor, though one I didn't focus on in this post. The sorts of large binary blobs that can take a lot of memory tend to be, well, large and contiguous, so perfect for moving between SSD and RAM at maximum speed. While I haven't seen benchmarks yet, the claim was 2x relative to their current systems, IIRC, which were already crazy fast at > 2GB/s. So it would probably do OK even just plain swapping, but really, really well moving these large blobs in and out, for example using mmap() and madvise().

PCIe Gen4 gives you sequential 5GB/s reads and even random reads at well above 4GB/s, this isn’t a page file on an ATA133 drive. In theory this can also be extended over TB/USB4 and ofc it can be extended over the network (however that’s the slowest part) this going to be quite a big thing especially for use cases like video editing if they offer a true unified memory as a lot of the latency doesn’t necessarily comes from the interface latency but from memcopy and translating between multiple address spaces.
