Very interesting thread; only in cases like this it's easier to see how much technology has advanced in the last couple (or more) decades. In the above past they needed almost an entire "motherboard" for something that takes today probably only part of a square millimeter in an SoC.
I think there have been some steps for open source drivers, but I haven't read much into it. https://blog.imaginationtech.com/imagination-and-our-commitment-to-open-source
For windows drivers I'm following a gentleman in another forum with ΜTT GPUs and while DX11 window drivers seem to...
I think they call the entire architecture after Rogue ALBIORIX (A, B, C & D)?. For the rather good joke above I'd think that their feet can't get more flat than that at the moment...
I posted it with a question mark, meaning take it with a grain of salt; it was at least the status when Rogue first appeared; I heard a rumor back then that with whatever they skipped and limited their architecture to DX10.0 compliance down from DX11.x meant a rough 50% of area saving per ALU...
Considering QCOM's smartphone ULP SoCs GPUs are >DX11 for generations now and they already have there RT support in hw, it doesn't make sense from any marketing POV. In fact it's what I'd call a marketing oxymoron, since DX12 was a "necessity" for the past few years now under Android, but not...
Then I was misled by this gentleman here
or that one also: https://www.notebookcheck.net/Qualcomm-Snapdragon-X-Elite-Adreno-GPU-Benchmarks-and-Specs.763558.0.html
As it stands the G3x GPU is far more interesting then the above GPU; the Elite X has a DX11 w/o RT GPU which IMHO from a marketing perspective is suicidal.

I don't think it'll be easy to find out, and not that it really matters in the "Apple world" but a GPU is either DX12 compliant or it isn't. It could even miss some DX11 requirements and no one...
John is unfortunately not working at IMG for quite some time now and it's even more unfortunate that no IMG hw engineer is here these days to give any form of insight on their architecture (and by the way there was no negative vibe or feeling while reading your former post nor in my reply to it...
