Git packfiles use delta compression, storing only the diff when a 10MB file changes by one line, while the objects table stores each version in full. A file modified 100 times takes about 1GB in Postgres versus maybe 50MB in a packfile. Postgres does TOAST and compress large values, but that’s compressing individual objects in isolation, not delta-compressing across versions the way packfiles do, so the storage overhead is real. A delta-compression layer that periodically repacks objects within Postgres, or offloads large blobs to S3 the way LFS does, is a natural next step. For most repositories it still won’t matter since the median repo is small and disk is cheap, and GitHub’s Spokes system made a similar trade-off years ago, storing three full uncompressed copies of every repository across data centres because redundancy and operational simplicity beat storage efficiency even at hundreds of exabytes.

带宽提升：TSV大幅缩短互连距离，显著提升数据传输速率，能够支持HBM4等超高带宽需求；延迟降低：桥接器内部的TSV路径比传统封装走线更短，有效降低数据通信延迟；功耗优化：短路径低电容，有助于降低整体系统功耗，符合高性能芯片的PPA（功耗、性能、面积）优化目标。，这一点在搜狗输入法2026中也有详细论述
