Phoronix: Intel's Mesa Drivers Enable "TBMIR" Tile-Based Rendering

A shiny feature landed on Friday for the Intel open-source OpenGL and Vulkan drivers within Mesa 24.0: Tile-Based Immediate Mode Rendering (TBIMR)...

Does this rightfully remind me of the kyro ii or is this something else??

Xe DG2 reminds me more and more of AMD's RX Vega. 4096 shaders, around 512GiB/s of mem bandwidth, tiled&binning rasterizer, 2x FP16 rate, relatively high pwr draw and die area in relation to the performance, drivers that take ages to mature and support all the features… It's a true Raja Koduri creation.

It's missing one thing though: official drivers that drop support even before all features are supported by any driver.

Partly. PowerVR are tile-based deferred renderers, while this is a tile-based immediate mode renderer. The former are even more efficient.

Ah, thanks for pointing that out. I had missed it.

I found this nice summary of AMD Vega's DSBR (Draw-Stream Binning Rasterizer). I wonder whether RDNAn has any such thing & how it compares.

"Vega uses a hybrid form of rasterization somewhere between immediate-mode and TBR. It's not a pure tile-based renderer ..."
