Shiny heatsink and FNApps support aside, the Killer K1 has a lower-clocked variant of Bigfoot Network’s network processing unit, also known as an NPU. The NPU found in the Killer K1 clocks at 333 MHz instead of the KillerNIC M1’s 400 MHz, how much of a performance difference 67 MHz makes is yet to be seen. Memory remains unchanged though, with 64 MB of DDR ram “to offer gamers a faster online gaming experience.”
If you didn’t like the idea of throwing away $250 on a network card, then maybe throwing away only $180 would be more up your alley. Other uses for your $180: Anything else.
