Depends which one, the HP ZBook Ultra uses LPDDR5x-8533, a dead match for what nvidia claims (273GB/sec). Although the DGX spark now costs $4,000 instead of the "starting at $2,999" mentioned a few months ago. So the bandwidth is dead even between AMD and Spark.

The HP ZBook Ultra is using DRAM parts rated for 8533MT/s but only operating at 8000MT/s, because 8000MT/s is the most the processor is rated for, but the memory manufacturers don't make parts with that non-stamdard speed grade.

  Ah, thanks, I didn't know that.
