My guess would be the video RAM that scrypt needs mucho bandwidth to is very very low on that mobile chipset. RAM speeds on btc are unimportant in the extreme. I think out of the two, you'd be better off btc mining.
Feel free to shoot some of that free electricity generated btc to me if you're feeling generous. 30x70MH/s = 2100MH/s it'll add up!
Topic: GPU cgminer on Mac OS X... slower than CPU? (Read 2723 times)
Can I ask how you got yours running? I managed to compile mine but cant seem to get it to select CPU only...
It's really nice that you care.... but I'd rather have help solving my problem.
The electricity really is free. We have our own wind turbines powering our building. We can't sell excess back to the grid - long story.
I really do have permission to use the machines any way I want.

I'm trying to find the best config settings for cgminer on Mac OS X. It runs just fine, but I'm only getting about 30kh/s with the scrypt settings I'm using. That's less than I get CPU mining on the same machine. If I switch to Bitcoin mining on the GPU, I get about 70 Mh/s.
Specs:
AMD Radeon HD 6750M
MacBook Pro 2.2 Ghz Core i7 cpu
OS X (10.
I know this isn't the most efficient use of my time or hardware, but my electricity is free and I have access to a lab with 30 of these machines every night, and the laptops are replaced every six months anyway so I'm not worried about killing them.
Any thoughts?
