The total performance of the HBM solution is dependent upon multiple factors:
  • The HBM stack operating frequency
  • The frequency of the AXI ports in the user application
  • The HBM address map selection
  • The global addressing mode
  • The reordering options selected within the HBM IP
  • The HBM stack temperature

The most important factor is how the user application logic is accessing the HBM through the AXI ports. System architects must consider how all these factors interact when evaluating the performance of the HBM memory solution in their design.
