All the data movement shouldn't even be a blip on your CPU usage. I think I get about 0% to 0.7% CPU usage on cgminer on a low-end Celeron.

If you're getting high CPU usage then something is wrong. Make sure "gen=0" is in the helixcoin.conf file. If you're on Linux make sure it's using the libOpenCL from the fglrx install and not the broken one from the AMD APP SDK (this might apply to Windows also, I have no idea). The broken SDK libopencl causes an irq storm.

That was an oversimplification, yes

Mind you, Sha3 is different from scrypt and i can confirm that the cpu usage is from the sha3 cgminer and not a wallet with setgenerate turned on.

I couldnt tell you exactly why sha3 uses cpu like it does, but there are no negative impacts observed by the dev team, so we quite like the algorithm

I am using Windows 7 64bit, and I too can confirm High usage of CPU with CGMiner when mining this coin I do not get as high a number I am getting around 50-60%

Low end celery here, seeing 50 to 60 % cpu usage. Got 2 x r9 290 running 1100 gpu and 650 memory, At stock gpu clock I can knock 37mv off gpu voltage but at 1100 I can only knock around 11mv off the voltage. Seeing a reduction of about 6 Celsius - less heat and noise - electricity usage probably down about 20 %

I have my mem down to 800, i cannot undervolt my 280X toxic as I have the gpu clocked to 1225 to get 410Mh/s my 7870 and 7770 are not worth undervolting
