In theory, the chiplet approach is supposed to address both yield and power issues (in cases where single-threaded perf is less important at least), just by being able to bin out the best execution units and assembling them together and making substantially larger aggregate parts running closer to their perf/Watt sweet spots. As the Anandtech review pounds on though, interconnect fabrics need more refinement in order to not overwhelm these gains with overhead, so maybe we'll need more EMIB/active interposer mesh solutions in the future instead of the passive organic substrate networks we see in this generation of Zen.
