What is delta, gpu and cpu hash and how can I reproduce them to get the stuff printed

[emir12]

Hi, I was searching and I had the identical CPU and GPU hash with a high delta and than the system restarted at a high delta again. So now I have a Delta, the hash and the prefix of 20 characters. How to get the privK and the adress from the hash?

I have recompilled vanitygen because I had the same issue, GPU and CPU hash are equal, prefix match but only delta, so changed some code now it prints:
CPU hash: 3ee4133d98fd0f285974026f2ecc4317bc6c7396
GPU hash: 3ee4133d98fd0f285974026f2ecc4317bc6c7396
Found delta: 442923 Start delta: 74448897
pkey (hex): 000000656e434c005a8947ed01000020ab9953ed0100006011b453ed01000000

I'm not sure what the above "pkey" means, it's the current value before it gets the actual key from somewhere.
I have a hard time reading the C source anyways
