I am using hashcat/cudahashcat with a WPA2 handshake.
My CPU is an i7 and the GPU is a Nvidia with Cuda.
The results of running for a few minutes are:
My CPU reports
(Speed/sec.: - plains, 2.7k words)
(Estimated time: 2 days)
My GPU reports:
(Speed.GPU.#1...: 12000 H/s)
(Estimated time: 10.5 days)
Why is my CPU so much faster than my GPU at cracking WPA2?
