At 450 MHz, the QDR II+ interface eliminates dead cycles between read and write turns, sustaining back-to-back throughput. That matters when the memory is feeding a packet processor or a high-speed FPGA fabric — every lost cycle costs line rate. The trade-off is tighter signal-integrity margin on the PCB: trace-length matching and termination are not optional at this speed.
