According to the company, it can create more direct die-to-die interconnects by stacking the silicon dies face-to-face (F2F) before bonding them together directly, reducing the distances between the computing, memory, and I/O chips in the package and removing the TSVs between them. The arrangement creates a high-density interconnect that can sling 10X more signals between silicon dies with minimal noise and stronger mechanical robustness. They consume 10X less power than the PHYs that
