Intel HD 630 Has 23 Compute Units

[RAlva5]

I was often told by many bloggers and posts regarding inntel HD 630 having 24 compute units but when I happen to check a openCL notepad when I was working regarding video editing, the notepad reported 23 compute units only. I'm sure Intel has some reason behind regarding this stuff so can someone teach me a literacy lesson about this for a moment? Thanks

What do you mean with "OpenCL notepad"?

Double-check with http://www.ozone3d.net/redirect.php?id=401 GPU Caps Viewer , https://opencl-z.sourceforge.io/ OpenCL-Z (ignore wrong icon) or AMD's CLINFO.EXE

I add some screenshots from my Broadwell for reference.

[RAlva5]

Indeed! Even openCL-Z reported 23 compute unit cores!

[RAlva5]

Even the Geeks3d GPU Caps viewer reported just 23 compute units too! Man! What will I do?

[RAlva5]

This is my hardware:

cpu = intel core i3-7100 @3.9 GHz speed

O.S. = windows 10, 64-bit

motherboard = H110 pro-VH plus, bios: 1.70

Ram = 4 GB

iGPU = intel HD630, newest driver installed, and rolled back to old driver but I get the same reading.

I'm using autoCAD and several other engineering tools and simulations like ANSYS, MS office, etc.

I am also doing video recording and conversion so I need every bit of power my computer can offer and I'm on a tight budget unable to upgrade or buy a discrete video card for the mean time so Intel please help.

Hello rollyalvarez3rd,

I understand you are having an inquiry about the compute units that come in Intel HD Graphics 630. In order to help you better I would like to gather more information about the configuration you have in the computer. Please attach to this thread the .txt file the Intel® System Support Utility will generate https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility Are you having a specific issue/error with the applications you are running? To attach a file, you must click "Use Advanced Editor" on the upper right hand corner of the response box, then the "attach" option will appear on the bottom right hand corner of the response box. Regards,Fred D.

The attached file is the generated txt info of my hardware. I don't have any problem or issue or error on any application I'm using. Before I installed the openCL and intel media SDK I already have that 23 compute units reading. I only installed OpenCL and intel media SDK later in hope to further accelerate my pc's video processing using default configuration only and yes I did experienced a little acceleration.

But after installing the intel media SDK and intel openCL and the drivers my reading have gotten worst. I now have only 4 compute units in openCL-Z, 23 in Geeks3D GPU caps viewer in gpu tab and only 4 in openCL tab.

Use the platform pulldown menu in GPUCapsViewer to switch between 4 CPU units and 23 GPU units.

FYI: an entry in Compubench matches your 23 units

Hello rollyalvarez3rd,

Thanks for the information you sent to me. I would like you to try updating some of the computer drivers. Please install this driver first, and then restart the computer http://download.msi.com/dvr_exe/intel_chipse_9_w10.zip http://download.msi.com/dvr_exe/intel_chipse_9_w10.zip Install this other driver, and then restart the computer one more time https://downloadcenter.intel.com/download/26836/Intel-Graphics-Driver-for-Windows-15-45-?product=96551 https://downloadcenter.intel.com/download/26836/Intel-Graphics-Driver-for-Windows-15-45-?product=96551 Let me know if issue persists or not. Regards,Fred D.

My bad! It turned out intel core i3-7100 has 27 compute cores after all as based on the readings. Geeks3D GPU Caps Viewer registered/reported an allocation of 4 compute units in Cpu OpenCL and 23 compute units in iGPU OpenCL. Did I interprete it right? If this is the case, can I make all 27 Compute units to work together or are they already working altogether by default? By the way, I already installed your recommended drivers and these are the readings which are also the same with the readings I got from the very beginning.

Seeing 23 compute units is normal. That is as it should be.

According to official Intel documentation (page 6 of https://01.org/sites/default/files/documentation/intel-gfx-prm-osrc-kbl-vol04-configurations.pdf https://01.org/sites/default/files/documentation/intel-gfx-prm-osrc-kbl-vol04-configurations.pdf), HD630 can have either 23 or 24 compute units. I.e. in some CPUs, a single compute unit is disabled ("binned") to increase yields.

It is very disappointing to see an Intel representative misleading customers this way, using a script (default answer for everything) instead of verifying if an issue exists. Asking customers to try various troubleshooting measures, when there is actually no problem, is not nice.

[RAlva5]

True! How did you know? You worked in Intel?

[KKrum1]

No, I simply follow technology news. The document I mentioned is public. https://01.org/linuxgraphics/hardware-specification-prms/2016-intelr-processors-based-kaby-lake-platform https://01.org/linuxgraphics/hardware-specification-prms/2016-intelr-processors-based-kaby-lake-platform

I see you have access to programmer's manual so I guess you are one of the programmers or developer of some sort or maybe not but thanks a lot for providing the right answer. Saves a lot of time trouble shooting. Kudos to you @kaarliskk!
