My first tests

[Galio]

I was curious so checked hashing algorithms. I ran some test but I'm confused now.

First, I made a program with C#(Okay, not the best one for this),
It search an SHA1 string from a simple word dictionary. To do this, It has to hash all word real time, and compare with the target hash.
It checks average 590k pw/sec.

Then, I wanted to test the same with GPU.
CudaHashCat checks average 5675k pw/sec.

With different method(brute force) it checks 3850M pw/sec.

The question is, are these realistic data, or did I do something wrong? What would be realistic?
CPU-GPU comparison(dictionary attack) might be good with 10x, but the brute force with nearly x1000 is a little bit too much.

All test use SHA1 hashing algorithm.

You cannot achieve any acceleration with a straight wordlist attack against a fast hash on GPU. You need an amplifier to gain acceleration. This is why your brute force speeds are so much faster.
