Is there an "Iris Plus Graphics 655" with only 47 EUs?

H-Takeda — Fri, 13 Nov 2020 13:07:37 GMT

Hi, I'm mainly enjoying running AI on NUC8i3BEH !
But then one day I realized.
Fewer GPU execution units (EU) are recognized in the App.

The SoC of NUC8i3BEH is i3-8109U.
The internal GPU of the i3-8109U is "Iris Plus Graphics 655".
Many documents found on Intel show the "Iris Plus Graphics 655" as being 48EU.

For example, the API of C for Metal displays 1 EU less.
(The Iris Plus Graphics 655 has 7 hardware threads in 1EU.
Thus, if there are 48 EUs, it should be "HW thread count : 336".)

Iris Plus Graphics 655 GT3 HW thread count: 329 GPU min frequency: 0 MHz GPU max frequency: 0 MHz Threads per group: 49

Is this a software problem?
However, several people have said that the Iris Plus Graphics 655 is 47EU.
https://en.wikichip.org/wiki/intel/core_i3/i3-8109u
https://www.tomshw.it/hardware/intel-prepara-bean-canyon-nuc-con-gpu-iris-plus-graphics

The above problem also appears on the i3-9100.
(The i3-9100 shows it as 23EU).

Is there an "Iris Plus Graphics 655" with only 47 EUs?
If you have a model that reduces the EU by one, why is that?

Hello H-Takeda,

Thank you for waiting.

After checking, this seems to be a software issue. Is there a way that you can test with a different reporting application? Perhabs CPU-Z or similar?

Additionally, please provide the following reports:

1. Run the Intel® System Support Utility (Intel® SSU) and attach the report generated:

Open the application, check the "Everything" box, and click on "Scan" to see the system and device information. By default, Intel® SSU will take you to the "Summary View".
Click on the menu where it says "Summary" to change to "Detailed View".
To save your scan, click on "Next", then "Save".
Use the option under the reply window to attach the report to the thread (Drag and drop here or browse files to attach).

2.DxDiag report:

In Windows, select Start and enter dxdiag into the search box on the taskbar. Select dxdiag from the results.
In the tool, select Save All Information for an easily shared format.

Sorry....
It seems that the reply was late.

Questions are now closed, but I'm just going to report.

My PC's OS is Linux (Ubuntu).
I did not know how to use DxDiag in Linux.

> Is there a way that you can test with a different reporting application?
I don't know of any other software that can display the EU as well as the above question.

SSU had a Linux version.
. /ssu.sh -o=All_Information.txt
The output text of this command is attached.

It may not be convincing, but that's all the information I can give you right now.
