Please fix the [formatting](http://bitcoin.stackexchange.com/editing-help): E.g. four spaces will give you "preformatted text", allowing you to present your config in a readable fashion. However, today, using a GPU instead of an ASIC for mining, is like using a spoon to compete with a dredger.

I think you are comparing speeds of mining SHA-256 with your mining Scrypt. Mining SHA-256 will have vastly higher hashrates. However, afaik even Litecoin has surpassed its GPU mining phase.

[Mining hardware comparision on Litecoin.info](https://litecoin.info/Mining_hardware_comparison) lists an "AMD 6530D" with a hashrate of `47 kH/s`. This is in the same range as what you achieve. The higher numbers you found were probably associated with a different mining algorithm instead of `Scrypt` which you are performing when mining Litecoin.

However, the age for GPU mining is over for Scrypt mining just as it is with Bitcoin mining. Although, I was talking about Bitcoin, this longer explanation applies to Litecoin just as well:
