They seem to be shipped with very high-end mobile devices (elitebooks,
dell XPS line, Microsoft's Surface) that do not have a discrete GPU.

I had been assuming they were compatible but had no proof.

First time I read about it. Wikipedia
https://en.wikipedia.org/wiki/Intel_HD_and_Iris_Graphics has a few
tables suggesting Iris is higher end stuff. I don't know about kernel
support.

Agree with Joost that Intel is typically well supported in LInux. I have
Skylate (gen6) system which i got fairly soon after they were released and
had no issues setting it up using ~amd64. If you want to run amd64 instead
you might need to keyword the kernel and X stuff.

ev says that everything up to Intel HD 620 is supported. It is
probably reasonable to assume that a HD 630 device is supported.

Hopefully that is the information you were after but I am still
somewhat confused and I think my confusion relevant to your original
question:

There are Intel HD devices, but there are also Iris devices. Per
marketing materials I found the Iris line is intended to be
distributed with higher-end computers for "professional" use. Do Iris
and HD devices actually differ in driver support or is it mostly the
name that shows up in lspci or Window's device manager that differs?

Adding MOZ_USE_OMTC=1 made no difference here.  Both before and after it 
reported:

 GPU Accelerated Windows0/1 Basic (OMTC)

  Mozilla-specific info... if you run either Firefox or sea Monkey or
Pale Moon web browser, include the line...

export MOZ_USE_OMTC=1

...in .bashrc to get maximum hardware acceleration.  For detailed info
about the program, go to "about:support", just like "about:config" and
"about:buildconfig".

Well, I suppose gen7 has advantages re power consumption and speed,
for uses other than 3D. For example, it supports faster RAM. I'm not
sure it's worth the price, though.

Thanks for the input.

If you just want 2D, then any GPU should work. Intel has very good support on 
Linux.

For desktop effect, the '3D' capabilities of the GPU are being used. Intel GPUs 
can handle those without issues. Unless the gen7 version isn't in the kernel 
yet, expect to have to wait. But I wouldn't expect to have to wait very long. 
But I wouldn't go for a newer gen7 CPU just for the GPU if not interested in 3D 
games.

OK, I need no 3D, and I don't game (not even occasionally :)) And I'm
just an openbox user!

Maybe someone with a 7th generation can share experience?

The gentoo WiKI has a page about this stuff. Reading now...

My laptop uses the integrated GPU 95÷ of the time. For the occasional game I 
want to play, I can enable the NVidia chip.

Support for Intel graphics is in the vanilla kernel, courtesy of Intel 
developers. With  6th generation i7, I can do most things. Only need the Nvidia 
chip for 3D games that need the higher performance.

With just the Intel GPU, I can enable all the eye-candy that KDE has to offer 
and still have a responsive desktop. I don't use it all as it can make the 
interface unusable due to the actual effects.
