I try answering your questions; please let me know if that could help you.
1. A product that specifies the 'Intel HD Graphics 520' chipset name, will not be using the 'Iris Graphics' chipset technology? ---- R/ True, because they are different.
2. A product that specifies the 'Intel Iris Graphic 540' chipset name, should be using the 'HD Graphics' chipset technology? ---- R/ No, as I said before Intel® Iris Graphics and Intel® HD Graphics are different.
3. If a product description specifies 'Intel HD Graphics 520' one should understand that this shipset is not the same as the 'Intel Iris Graphics' chipset. ---- R/ True, it is not the same chipset.
The 'Intel HD Graphic 520' is not an 'Iris Graphics' chipset? ---- R/ Yes, they are not the same, they both are High-end graphics but the Pro one is the top the line.
The 'Intel Iris Graphics 540' is not an 'Iris Pro Graphics' chipset? ---- R/ yes, it is not because they are two different Intel Graphics; Iris is the word that Intel marketing uses for High-end.
Thought I would just check in and check if the information provided previously answered your inquiry.
Just to add some information to this.
The Intel® Iris Graphics /Pro is more gaming intended and high graphics performance compared to Intel® HD Graphics.
The Intel® HD Graphics are intended for daily usage, watching movies, playing videos in high resolution.
Basically, if you are into gaming and high graphics performance, go with Intel® Iris Graphics.
Watching videos or movies in high resolutions, Intel® HD Graphics.
Hope this information is useful for you.
I look forward to hearing from you.
Thanks so much for your reply.
I asked the question because I am not sure how the graphics technology is packaged and labeled.
And I've been reading through marketing information, reviews and talking with folks who sell computers that use Intel processors. Some folks thought they were the same, others did not.
I am interested in the Intel Iris graphics technology for software product development, for supporting low-medium graphics, photo and 3D processing.
Thank you for taking time to clear this up for me.
