Phoronix: Mesh/Task Shader Queries Land For RADV With RDNA2, RDNA3 Support On The Way

Thanks to prolific RADV driver developer Samuel Pitoiset of Valve's Linux graphics team, mesh/task shader queries have landed for GFX10.3 (RDNA2) with the in-development Mesa 24.0 while support for GFX11 (RDNA3) graphics cards is on the way...

Night fishing. You drop a submersible task shader sensor into the ocean, shine a bright light on it, and when enough fish block enough light to shade the sensor it sends out a signal to quick launch a mesh net to capture the fish.

Why do you think their GPU code names follow the $COLOR $FISH formula?

Different colors produce different kinds of shades to capture different kinds of fish.

Night fishing.

If you have to spend too much time trying to come up with the "joke," it's a clue that it's not funny.

This is funny:

My mom, like you, is a complete social retard. She got shit-canned from a temp job at the local highschool for telling a joke about a terrorist with an explosive vest at a highschool. It was a long, lame-ass joke and there was plenty of lead-up time for her to figure out in advance exactly WTF she was doing.

We reap what we sow.

Okay, I've seen everything

Nvidia has a really good explanation for why and how about mesh shaders.

Why "Turing"?

It seems non-NVIDIA architectures are at disadvantage, maybe Intel less than AMD.

What do you mean "why Turing"? It's just a code name for that GPU... Completely irrelevant to mesh shaders.

And Nvidia forefronting the standard doesn't mean other brands can't be good at it.

Weren’t mesh shaders pushed hard by Microsoft for DX12 Ultimate?

So: I think perhaps there is some questioning about why Nvidia had the first and most “solid” implementation, whereas RDNA2/3 and Intel Xe/Gen 12 and Arc/Alchemist lagged along later to the party.

Perhaps the answer is “marketing bucks” - or it’s just that NVIDIA has more R&D cash to make these twizzler shaders.

It was NVidia's idea, and MS ran with it. That happens all the time - most of the stuff in DirectX is coming from the 3 hardware vendors, originally, and MS is figuring out what they like and want to promote.
