  1. HBM3 vs HBM2e Memory Capacity: 64 GiB (16x4(?)) vs 24 GiB Transfer Rate: 7200 MT/s vs 3200 NT/s Bandwidth: 921 GB/s vs 410 GB/s I know noone actually manufactures 24 GiB HBM2e, but it's in the spec, so I'll include it here. @tomshardware/1446462723324354561

      * MT/s, not NT/s I believe there's 3600 MT/s HBM2e memory available too, but I don't think that's in the original spec. For some reference, SK Hynix said their "HBM3" is 665 GB/s bandwidth and 5200 MT/s transfer rate.

        That's weird, Rambus is claiming HBM3 is 8400 MT/s and 1075 GB/s... Source: semiengineering.com/hbm3s-impact-on-chip-design/
