Has TI done any Ethernet/power benchmarks yet with the new TM4C1294 Connected LaunchPad?
I have seen some competition Cortex-M3/M4 (also 120MHz parts in this case) platforms benchmarked and the Ethernet performance was much slower than expected.
Since TI is integrating the PHY into the Tiva C chips maybe this approach is much faster and more energy efficient.
