Sorry for lazy question but some people here know this off top of their head so asking. Memory bandwidth of this chip?

Last time I check an NVidia situation was for DGX Spark (the GB10 chip), it has regular LPDDR5X which by JEDEC standard cannot go beyond ~270 GB/sec, ie 8533 Mbit/s on a 256 lanes bus.

So yeah Lemire seems to go "OMG unified memory, they're following Apple path..." ok, but Apple pulled off a much faster interconnect, 800 GB/s ballpark, and I'm trying to understand (not really, I'm asking you to try understand, he he) how is this laptop faring in that regard.

This is the same chip and same memory. Only difference is it is going in a laptop, so will be more thermally limited.

Gotcha, thanks for explaining. Indeed I noticed it was 128G of memory just like the DGX.
