Intel HD Graphics

No way, the 3770 cpu is faster than a hd 400 gpu? I thought the worst gpu kills the best cpu. Oh well I stopped the hd 4000. I finally got some lancelots and didn't want to shorten the 3770s life.

Heh, now you know better... The worst AMD GPU is better than the best CPU. The same is not true for intel GPUs, or even Nvidia (to a lesser extent with the 210 for example). Intel GPUs are a token gesture with adequate graphics for most normal people; they are hopeless for any high performance application, including opencl.

So cpu mining isn't that bad
I was wasting hd 4000 because i couldn't cpu mine on the 3770
But then again the hd 4000 took 5 watts, not 75

A couple thousand coders with specs provided by AMD haven't made OpenCL capable drivers for AMD GPUs.  Doing it in the dark is never going to happen. 

Just a peeve here - We had coders "tricking" GPUs into running semi-arbitrary code considerably faster than CPUs by writing it as custom shader routines, years before OpenCL hit the scene (Google for "GLSL" or "Cg").  So yes, the possibility does exist of mining on a completely non-CL-supporting platform.

That said, shaders (at least back then) had a fairly limited set of available operations they could do (mostly linear algebraic transforms on single or half precision floats, not bitwise ops on integers), and an incredibly small stack space (on the order of 256 bytes) - Good luck implementing SHA256 under those conditions.

Folding@Home made a client for ATI 1900 cards wich ran on DirectX 9. Yup, science computing on DirectX 9.

Back then OpenCL didn't even exist, not even CAL (CAL is like CUDA for ATI, supported since ATI 2000 if i am right)

My intel 3820-E is putting out 50 Kh/s, so yes, there are CPUs that can do better than some low end (< $100) GPUs.

Is it more price efficient? No.

mhs or khs? if it's khs then yeah any gpu would do better. I have a 5 year old nvidia that does 3 mhs

Can you please tell us how did youdo it?

Might want to read the dates on the thread before asking for 4 year old information
