Further improvements in system performance are often limited by the achievable bandwidth between processor and memory. In this paper we look at interposer-based and stacked solutions to integrate processor and memory into a high performance system. The comparison reveals the current advantages of interposer-solutions. This is underlined by thermal and technological considerations. Even though physical design tradeoffs are existent, we show an actual implementation of the chosen technology.
