What processors have an internal Gen11 GPU *with* FP64 (double precision) enabled?

FP64 seems to be disabled in Gen11 Ice Lake iGPUs. Is FP64 usually disabled for iGPUs in laptop processors? What about Gen11 iGPU desktop processors? Is FP64 *always* disabled in consumer Gen11 iGPUs? If so, will there be Xeon processors with Gen11 iGPU with FP64 enabled?

Hello JOdio

 

Thank you for posting on the Intel® communities.

 

Please allow me to look into your inquiry regarding support for Double Point Precision Computing (FP64) on Intel® Integrated Graphics on Intel® Processors.

 

As soon as I have more details I will be posting back.

Let me phrase the question differently (since Gen11 desktop chips are not out yet):

 

Have FP64 enabled iGPUs ever been available in consumer desktop chips?

 

Because a desktop chip should not be so concerned with the small energy saving that would result from disabling FP64. Even on a laptop. I'm guessing that on a laptop, those FP64 cores are removed completely and are not actually disabled. Is that correct?

Hello JOdio,

 

Regarding your inquiry, I would like to inform you that FP64 is supported on 6th, 7th, 8th and 9th Generation Processors including Apollo Lake and Gemini Lake.

Also, this feature is not included in the 10th Generation Processors.

 

I am still investigating regarding your additional inquiries from the last post. As soon as I have more details, I will be posting back.

Hello JOdio,

Hope you are doing fine.

 

Please let me share the following information regarding your inquiries:

 

1- Regarding if FP64 enabled Integrated Graphics Processing Unit (iGPU) has been ever available in consumer desktop chips, yes, it is enabled on 6th, 7th, 8th and 9th Generation processors including Apollo Lake and Gemini Lake.

 

2- Regarding if those FP64 cores are removed completely and are not actually disabled on laptops, FP64 is enabled on 6th, 7th, 8th and 9th Generation processors (desktop and mobile) including Apollo Lake and Gemini Lake. In this case, please check with the Laptop manufacturer for any potential customization that is outside Intel's control.

 

Should you have additional inquiries, please let me know.
