    That's why CPU suck at it.
    but it's same massively parallel workload which is amenable to just throwing more cores at it. cpu will suck at it, but it will nicely scale with number of cores just like videocard

      Yes, and since the GPU have added hundreds of cores per generation while CPUs did not, performance expected on GPUs for this parallel workload has increased much faster than expected performance on CPU.

      That's what I said in the original post you quoted. That as time goes on, the result of CPU running LLVM and same age GPU rendering will get further and further apart in a performance graph

      And I'm still right

        b) it has implemented all the individual features that we wrapped up into GL 4.4, it doesn't mean it can advertise GL 4.4 until it has all the prior features done as well.

        It's likely GL 4.3 will be all it advertises once I've completed all the GL 4.5 features until it passes conformance.

        Dave.
        a) My bad, I've used word "conformant" as replacement for "meets requirements for". Sorry.

        b) I'm aware of this fact. I just pointed this jokingly.

        Good to know, thank you for answer.
