Hi,

You guys are not paying attention. GPU is 10x
more performant than CPU for certain integerish
payload on the pi-WAM. 11.4 GLips on a GPU is

ca 10x more than 1.7 GLips on a CPU:

Parallel π-WAM: 1.7 Giga Lips on a CPU
https://medium.com/2989/8a984e75af44

So GPUs are by way not dead. Especially since
they can be accessed via WebGPU / WGSL. But
the line between GPU and CPU increasingly

blurrs. It already happens for APUs in
that unified memory puts them into the same
RAM space. But the programming means differ.

Also unified memory doesn't mean that
the GPU sees memory the same way as a CPU.
To get a taste how a GPU sees memory:

Memory Model
     Execution Barriers
     Fence and Address Spaces
     Memory Model GFX6-GFX9
     Memory Model GFX90A
     Memory Model GFX942
     Memory Model GFX10-GFX11
     Memory Model GFX12
     Memory Model GFX125x

https://llvm.org/docs/AMDGPUUsage.html

WebGPU / WGSL seems to have good support,
since it can have Vulkan, Direct 12, or Metal
as GPU low level interface. Maybe more

platforms, something NVIDIA I guess. But I
don't know the details, how this is all done.

Bye
