So, I decided to try Litecoin mining today, so I'm new to it, and pretty new to bitcoin and altcoins in general.
I have a 2.2 gHz quad-core Intel CPU with hyper-threading, which turbos to 3.3 gHz I believe, and with all 8 logical cores running I can clock about 40-50 khash/s. Now, I have an AMD Radeon 6750M, but with only 512 MB of memory. (I know, so little memory is sort of a bottleneck for a fairly good card.) However, when I try GPU mining it can get only about 25-30 khash/s. It's a fairly good graphics card, so I don't know why it's so slow. The parameters I have on it are:
vector 1
worksize 64
intensity 16
I have a mac, and I'm using it cgminer. Perhaps I just didn't tune it well enough.
