6.1. High Bandwidth Memory (HBM2E) DRAM Bandwidth

For each HBM2E DRAM in an Intel Agilex® 7 device, there are eight channels of 128-bits each. The following example illustrates the calculation of bandwidth offered by one HBM2E interface.

Assuming an interface running at 1.6 GHz: 128 DQ × 1.6 GHz = 204.8 Gbps

  • The interface operates in double data-rate mode, so the total bandwidth per HBM2E is: 204.8 Gbps × 2 = 409.6 Gbps.
  • The total bandwidth for the HBM2E interface is: 409.6 Gbps × 8 channels = 409.6 GByte/sec.
  • If the HBM2E controller operates at 90% efficiency, the effective bandwidth is: 409.6 GByte/sec × 0.9 = ~368 GByte/sec.
