Tell me! I tried both 32 and 64 sdk and cgminer can't find cl devices :/

Hmm, I have small Win7 SP1 32bit partion only for mining. You need 9.17.10.2792 GPU driver from Intel and I currently use the 2013 BETA OpenCL SDK (You need the same arch as your Win is eg 32bit OpenCL for 32bit Win), then I just downloaded the precompiled CGMiner (don't want to compile on Winblows Cheesy

BTW 2.11.3 it is) and started the app. Dunno why it doesn't work on your PC Huh

Intel 4000 can do OpenCL. In fact I'm mining on it right now Wink

with 1150MHz you can get about 12MH/s with ~8W power consumption, unfortunately my GPU in that ultrabook is throttling so I get about 10MH/s with ~5W power consumption of the GPU.
Also, it only works under M$ Winsh!t Vista/7 since the OpenCL support for Linux was put on hold.

Hope it helps Wink

My ivy bridge hd 4000 should have opencl now

Did anyone get this working? I'd like to mine on my Intel hd 4000 cpu while waiting for bfl.

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.

We dont know!

Some reviews shows up that DirectCompute performance is well over than an AMD A8, its not the same than OpenCL performance, OK, but someone needs to try it out.

LOL, you may be the first person to estimate even less than I would have.

It only has 16 stream processors, and the 5830 has 1600 stream processors.

My CPU has 64 stream processors (or can do 64 parallel computations) and I only get ~7Mhash, I'd be surprised if the Intel HD got over 5 Mhash.

Are Intel's "Execution Units" directly comparable to AMD's "Stream Processors"? I'd be more curious to see what the power consumption will be for the respective hash rate.

That's the million BTC question. You can look at the performance data from the 680 to see that a new CUDA core isn't comparable to at VLIW5 SP, so we likely won't know until someone tests it if they are comparable.
If one EU does equal one VLIW5 SP (and assuming they can run at the 1.15GHz boost rate all the time), you'd expect to see about 5MH/s out of HD4000. The 5830 only has 1120 SPs, btw.

Here is my best guess:
2. Intel HD Graphics = 3-10 mhash

That seems a bit optimistic IMO. I'm guessing it would be around 500khash.

QuickSync doesnt even use OpenCL or the gpu (as in shaders), its basically a built-in asic for videotranscoding. I find it very easy to believe they achieve that kind of performance.

There is no data on Ivy Bridge OpenCL power yet? i know it should be weak, but it worth a look, Intel does miracles, when Quick Sync performance becomed public, no one could belive it....

Ah shoot you are right! This OpenCL SDK only supports Ivy Bridge integrated GPU's (HD 4000/2500). Dammit! Well, the SDK is detected in cgminer at least:

I will enable my Sandy Bridge GPU in the BIOS, install drivers, install Lucid Logix bullshit if I have to, install SDK, fiddle and then report if I can get stuff working. Thanks.

Sandy-Bridge GPU is not OpenCL capable (unless I missed an announcement by Intel)

OK, then if it already works how do we pass options to cgminer to fire it up?

Try: cgminer -n

Should report any SDKs installed and any OpenCL compatible GPUs detected. Presumably the GPUs need drivers that advertise their OpenCL capability.
