	Read amplification captures how much DDR traffic is required to retransmit a given amount of data. Chain-based caches tend to chase pointers and issue scattered reads, resulting in high amplification and poor DDR efficiency. HPPC combines a unified ring layout with range-aware NACK coalescing to produce long contiguous read windows, so the bytes read from DDR closely match the bytes retransmitted, driving RAdata toward 1. This leaves more DDR bandwidth headroom for cloning and reduces latency variability.
