But do you think you'll reach 1.8 TB/s?

  Quite likely, but the transfer throughput is required in bursts, not necessarily continously. Let me put it this way: what I care about is how quickly data arrives after a bunch of shader threads request it. Throughput is one way for hardware to reduce that time. The other way is to hide the latency (GPUs do a lot to keep themselves busy while waiting for memory), but those strategies can only do so much. Lower memory throughput almost always leads to a longer runtime of GPU calls in practice, and thus lower update rates.

    Empirically, these benchmarks are showing it doesn't make much difference once you reach this level of bandwidth: https://www.tomshardware.com/pc-components/gpus/early-rtx-5090d-v2-benchmarks-suggest-that-maybe-384-bit-memory-is-just-fine-after-all-nerfed-china-market-gpu-runs-within-2-2-percent-of-5090d-in-some-tests https://www.tomshardware.com/pc-components/gpus/early-rtx-50...
