Arm Mali G2-Ultra NX GPU: desktop-class mobile gameplay with AI-native graphics (newsroom.arm.com)

The Pixel 10 and 11 GPUs are offensively bad. Not only are the Power VR GPUs slow, and less capable feature wise than Mali and Adreno (Xclipse is still around too!), but the tile Google put in the Pixel 11 is actually an _older_ design than what they put in the Pixel 10. They just clocked it higher to make up the performance difference.

And then Google has the gall to charge basically flagship prices for their under powered junk.

Personally I don't buy flagship phones because I don't use their full compute capabilities anyway, but a Pixel 11 would cost 2x what I paid for my Pixel 8. For 0 GPU performance improvement.

I just can't wait to see it being tested in an actual phone. So far all the data are done on development board. If they are really as good as everything we have read so far, both Mediatek and Qualcomm are in big trouble.

Why did that happen?

Unfortunate wording?

Because most game developers aren't religious about APIs, they implement an abstraction layer in their engine, a practice since the heterogeneous 8 and 16 bit days, where all major games were mostly coded in Assembly, and move on.

Any conference talk schedule at one of these conferences (https://gameconfguide.com) will prove the point of how little they care.

It is all about gameplay, taking advantage of gaming IP, franchaises, how to squeeze the ultimate performance out of specific hardware, user engagement,....

You will find an occasional talk about open APIs, probably even done by some Khronos folks, and that's it.

If they open-sourced their userland drivers, and/or released their internal technical documentation, which would have a similar effect, they would open themselves to at least two big problems.

First, they would spill all of their secret sauce for others to "draw inspiration" from. And there is a lot of expensive secret sauce in there. Not all of it is protected by parents either; more on that below.

Second, they would make it a lot easier for competitors and patent trolls alike to seek litigation. One of the criteria thech companies have for filing a patent is how easy is it to detect when it is being violated. Open source your stuff, and you make it much easier for the competition to detect any violation.

And it is not like these companies are violating patents intentionally; much the opposite. But there are only so many ways to implement Vulkan or DirectX, and completely independent teams will come up with similar enough solutions, and with broad enough patents, that there will be overlap every now and then. That is why they file patents in the first place. Only the high cost of litigation and the risk of mutually-assured destruction keeps legitimate vendors from rattling sabers more often.

Then you have NVidia with their immense investment and advantage on the software side, from the CUDA runtime to countless libraries like CUBLAS and cuDNN. That investment goes much beyond a relatively simple Vulkan/DirectX driver.

So the question is less "why don't more of them open-source userland". The question is "why do any of them do it"?

All the mainline kernel support is reverse-engineered. No help from Arm.

Thus there is a considerable lag for the support of newer Mali generations.

Some Linux distributions for various embedded computers with Arm-based CPUs and GPUs use closed-source GPU drivers from Arm, not the reverse-engineered Linux drivers, when the Mali versions are newer than supported by the kernel and Mesa.

The Arm GPUs do not have public technical documentation, not even at the level of NVIDIA, much less something comparable with AMD and Intel.
