phoronix-test-suite VS MoltenVK

I think they do a lot of good stuff, like LTO and PGO.

But in benchmarks you sometimes see like a 4x speedup compared to ubuntu, which is obviously not due to superior compilers.

For example:

https://github.com/phoronix-test-suite/phoronix-test-suite/i...

phoronix test suite has a benchmark for pretty much everything

I think you can use the Phoronix Test Suite for build time bench mark testing

But I have no clue what could I use for actual benchmarking part. I know about Phoronix Test Suite, but from what I can tell, it’s designed to compile the tested software on its own, ignoring the pre-installed software—see Q: Why does the Phoronix Test Suite not use my distribution's package management system for acquiring all needed packages?:

I grabbed the https://www.phoronix-test-suite.com/ on a whim.

Using the phoronix test suite when I attempt to run it on my Linux machine, it opens the game in full screen on the 2nd monitor.

If you want an all-in-one, maybe something like the Phoronix Test Suite? You can run just the disk tests, if that's all you want. https://www.phoronix-test-suite.com/

There is the Phoronix test suite. Lots of benchmarks etc there,

Translating between rendering APIs is not really the problem. The GPU design is more different than the API is.

Khronos maintains MoltenVk though, which is "official" as it gets: https://github.com/KhronosGroup/MoltenVK

...technically, Vulkan on Windows is also only supported via 3rd-parties (the GPU vendors), Microsoft doesn't support Vulkan either ;)

MoltenVK implements large parts of Vulkan on top of Metal for Apple systems. It isn't full Vulkan but it makes porting Vulkan games to OS X easier.

That's cool. Maybe I haven't thought enough about this. Let me check it out. FWIW it's this PR that you are referring to I think: https://github.com/KhronosGroup/MoltenVK/pull/1815/

For Metal specifically, they could adopt and contribute to Vulkan and get access to a lot more software. Right now you need to use a compatibility layer, and surely Apple could just support both APIs natively with much lower overhead. But they don't, because it nudges developers to stick to the Apple ecosystem instead of being able to support multiple platforms.

At the moment the most promising thing is MoltenVK (DX12 -> DXVK -> Vulkan -> MoltenVK -> Metal), but the development is not that quick mainly because there aren't tons of developer that works at the same time on the project. It's not actually a Metal related problem at the moment (they have a road map of things that they can be achieved with Metal 3 like Mesh shader and Geometry shader).

What you asked is already existed for at least 8 years. Yeah EIGHT years. It's called "MoltenVK". So far it's the only implementation of Vulkan for macOS. Basically it's a wrapper that runs on top of Metal API.
