What is D-Wave's "Pegasus" architecture?

Pegasus is the first fundamental change in D-Wave's architecture since the D-Wave One. The D-Wave Two, 2X, and 2000Q all used the "Chimera" architecture, which consisted of unit cells of $K_{4,4}$ ...

Why did D-Wave choose the Chimera graph the way they did?

You are right that $K_{3,3}$ is non-planar, but as you said yourself, a larger $k$ is much better. If they could do $K_{1000,1000}$ that would be nice, because each qubit could be coupled to 1002 ...

What is D-Wave's "Pegasus" architecture?

How is D-Wave's Pegasus architecture different from the Chimera architecture? See: "Pegasus: The second connectivity graph for large-scale quantum annealing hardware" (Jan 22 2019), by Nike Dattani (...
