Intel HD Graphics

[shivansps]

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.

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.

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

[bitpop]

My ivy bridge hd 4000 should have opencl now

[Redi]

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

[bitpop]

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

[bitpop]

I'll keep trying. Wasn't sure whether arch needs to match os or app. I also have driver issues with Windows server 2012.

Who doesn't have issues with Windows?
Best would be to use Linux everywhere, but since the dev who worked on OpenSource OpenCL with Intel GPU left the company there is only little hope...

BTW why not use the same arch for all? 64bit Win + 64bit SDK + 64bit app?

[bitpop]

Got it working! My i7-3770 hd 4000 does 12mh/s. Thanks!

There is no cgminer x64 is there?

I forget how bad cpu mining is and can't really test it any more. But is 12mh/s much better than cpu mining? I miss mining and have been waiting for so long for bfl so this will be fun for a while.

[bitpop]

Can anyone tell me cpu only mining speed of a i7-3770? Wanna make sure gpu mining is worthwhile and whether to try to add cpu mining. I don't think 12mh/s is bad for a "free" gpu though. Just not sure if it's any faster than cpu only.

I think its 5 or 6 mhs. at what, ~70 watts?

vs 12 mh/s @ ~5 watts

[bitpop]

Yeah amazing, mines using exactly 5.9w

[bitpop]

If someone made us an optimized ocl kernel we could probably push a few more mhs :-)

[Redi]

That would be great IMHO. I know that this GPU is extremely low-end, but since I have free electricity and since I'm on that ultrabook almost all the time I like to use it

[bitpop]

My home server is always on too. You're lucky you get the same performance ;-)

[shivansps]

Any numbers on Haswell HD4600? it seems to wipe the floor with the 7660D on OpenCL performance...

[Herp-a-derp]

My ivy bridge hd 4000 should have opencl now

I have one of these on my laptop and the Bitminter client mines on it, slowly  :

Edit: Before anyone asks, no I don't mine on my laptop, I downloaded the client simply to see what it looked like and was surprised to see the Intel HD device available.

bitpop:  to answer some of your questions.. I have a similar chip and get about 12Mh/s on the Intel 4000 and 27Mh/s using all cores of the 3770, slightly over clocked.

If you want to play with it, I use minerd.exe, which I can't remember where I found, hehe.  I also use a mining_proxy locally to accept its work and translate it to stratum, since it only supports getwork.

So, basically, if you want the machine to do nothing else, that cpu/gpu can do about 39mh/s at considerable wattage (havent measured, because I don't mine with it, but maxing the cores of that chip is going to easily be over 100w.)
