Vulkan on IGPU?

[xnoobftw]

Will vulkan improve fps of intel onboard graphics? Lets say dota 2 is the game here and a haswell i5 processor is the cpu of interest

I have yet to see tests of that. But at the very least it won't do much worse.

It could go either way, depending on the state of Intel's Vulkan driver implementation. It seems unlikely that it would perform worse than OpenGL, but the only way to know is for someone to test it. And I haven't seen that yet.

 

It's certainly worth trying, if you have a Vulkan game handy.

There is no Intel IGP yet with Vulkan support afaik, so we'll have to see once that becomes available.

Intel made a video where they "claim" they will gain FPS tough I am not sure their driver support Vulkan yet...

I was hoping that vulkan would help in igpu cases but isnt vulkan suppose to help with communication between cpu and gpu and to be able to offset load from core 0 to all cores equally?

In theory, yes, I suppose Vulkan could help any GPU to perform better. It's just an open question at the moment whether the optimization of the games and Intel's driver is to the point where Vulkan actually does help an Intel GPU in a real game yet.

 

Both DX12 and Vulkan have the potential to do what you say, but it's all in the implementation. Some current games run poorer in DX12 mode than DX11, or gain very little. Some perform better. Just as it has always been, some games are better optimized than others regardless of the API. It will probably be the same for Vulkan, though there are currently fewer games attempting to offer Vulkan support.

Does that mean that sli/crossfire will have lesser of a bottleneck when it comes to like 3way and 4 way with vulkan/dx12? Since cpu usually cannot keep up with 3 or more gpus due to core 0 having majority of the load(so new api = work load spreaded = higher cpu overhead?)

Only if the developers choose to implement the multi-GPU features that come with the API. While Vulkan is still in its infancy and devs haven't completely figured it out yet, it's unlikely that games will come with the full feature suite.

It's possible that really well-optimized DX12/Vulkan could do that, but again, that's a matter of implementation. These are all just features that game developers can choose to invest resources in, or not. So far we don't have any games where either DX12 or Vulkan is a "magic bullet" for CPU performance, and it may never be quite that effective. These APIs have the potential to address more processing threads, but we don't know how much that actually helps until we see benchmarks for games that make extensive use of it.

 

Also, I'm not sure if this is what you're saying, but CPU bottlenecking is not the only problem holding back 3- and 4-way graphics configurations. There's a few games where it works wonderfully (and things like 3DMark, of course), and in the rest you'll get 0–30% scaling from the third card. Usually, that's an issue of support and optimization from the game and/or driver, not necessarily a CPU bottleneck.
