Network Speed

Kestrel's network "highway" has twice as many lanes as Eagle's. Vehicles (or data) travel twice as fast, simultaneously, and—like Kestrel's compute nodes—all communicating with one another at the same time.

Energy-per-Computation
Efficiency

Kestrel can do 2.2 times more calculations per watt of energy than Eagle. That’s like traveling more than twice as far on a single charge.
