Very high likelihood that your CPU is hashing out far lower difficulty shares than your GPU.

There is no way on earth a 4770k keeps up with any gpu mining x11.

Thanks,

i have no idea why i didn't think of that.

Total Dur moment once i read your post.
Always check the share difficulty Smiley


Thanks for sharing that, I didn't knew it..( noob here).

May I know your setting of the 280x  Huh

My setting for my GPU are in the second screen shot.

Here is the new miner you can download it.

no doubt a newbie  Grin

The pool always try to achieve similar share finding rates for miners by adjusting the difficulty.

What is the difference in coin earning rate at pool for both cases?

3.65 MH/s? Bullshit most likely.

new sgminer can achieve that pretty easily, i'm running at same speed my 280x
Really? Which version? I am using the one of lasybear and get 3.35Mh/s.

you need to oc the core to 1200 or something, to reach that hash

I have a R9 280X pulling 3.65Mh/s

I have an 8 core I7 4770K with 7 cores running pulling 500 Khash/s

Both have been started within 1 minute of each other

The CPU has submitted 3330 shares and the GPU has submitted 3690 shares.

Shouldn't the GPU vastly be out performing the CPU?

Thoughts?
