LAN Speed Test Lite
Ethernet speeds have now reached a limit to the external hardware such as the router and cable rather than the port or LAN chip. Comparing the results below, it shows that the Intel I219V performs very well and consistently across all of the motherboards.
Passmark Performance Test 8 – Ethernet
A slightly poorer result here, but still within the margin of error for the LAN chip itself, only a few Mbps behind the ASUS Z170 M8H.
Passmark Performance Test 8 – CPU Work Load
Generally the Intel LAN options are more efficient than the Killer version, however, the I219V sees a rise in CPU usage which possibly points towards Intel sacrificing this to get a higher throughput.
