Vulkan is a low-overhead, cross-platform 3D graphics and compute API first announced at GDC 2015 by the Khronos Group.[10][11][12] The Vulkan API was initially referred to as the "next generation OpenGL initiative," or "OpenGL next[13]" by Khronos, but use of those names were discontinued once the Vulkan name was announced.[14] Vulkan is derived from and built upon components of AMD's Mantle API, which was donated by AMD to Khronos with the intent of giving Khronos a foundation on which to begin developing a low-level API that they could standardize across the industry, much like OpenGL.[3][10][15][16][17][18][19]
Like OpenGL, Vulkan targets high-performance realtime 3D graphics applications such as videogames and interactive media across all platforms, and offers higher performance and lower CPU usage, much like Direct3D 12 and Mantle. Vulkan also has the ability to render 2D graphics applications,[20] however it is generally suited for 3D. In addition to its lower CPU usage, Vulkan is also able to better distribute work amongst multiple CPU cores.[21]
Features
Vulkan is intended to provide a variety of advantages over other APIs as well as its spiritual predecessor, OpenGL. Vulkan offers lower overhead, more direct control over the GPU, and lower CPU usage.[12] Intended advantages include:
- Vulkan API is well suited for high-end graphics cards as well as for graphics solution present on mobile devices (OpenGL had a specific sub-set for mobile devices called OpenGL ES).
- In contrast to DirectX 12, Vulkan is available on multiple modern operating systems; like OpenGL, the Vulkan API is not locked to a single OS or device form factor. As of release, Vulkan runs on Windows 7, Windows 8, Windows 10, Tizen, Linux, and Android.
- Reduced driver overhead, reducing CPU workloads.[22]
- Reduced load on CPUs through the use of batching, leaving the CPU free to do additional computation or rendering than otherwise.[23]
- Better scaling on multi-core CPUs. Direct3D 11 and OpenGL 4 were initially designed for use with single-core CPUs and only received augmentation to be executed on multi-cores. Even when application developers use the augmentations, the API regularly do not scale well on multi-cores.[24]
- OpenGL uses the high-level language GLSL for writing shaders which forces each OpenGL driver to implement its own compiler for GLSL that executes at application runtime to translate the program's shaders into the GPU's machine code. Vulkan drivers are supposed to ingest instead shaders already translated into an intermediate binary format called SPIR-V (Standard Portable Intermediate Representation), analogous to the binary format that HLSL shaders are compiled into in Direct3D. By allowing shader pre-compilation, application initialization speed is improved and a larger variety of shaders can be used per scene. A Vulkan driver only needs to do GPU specific optimization and code generation, resulting in easier driver maintenance, and smaller driver packages in theory (as GPU vendors still have to include OpenGL/CL).[25]
- Unified management of compute kernels and graphical shaders, eliminating the need to use a separate compute API in conjunction with a graphics API.
OpenGL | Vulkan[26] |
---|---|
one single global state machine | object-based with no global state |
state is tied to a single context | all state concepts are localized to a command buffer |
GPU memory and synchronization are usually hidden | explicit control over memory management and synchronization |
extensive error checking | Vulkan drivers do no error checking at runtime, there is validation layer for developers |
Planned features
At SIGGRAPH 2016, Khronos announced that Vulkan would be getting support for automatic multi-GPU features, similar to what is offered by DirectX 12.[27] Multi-GPU support included in-API removes the need for SLi or Crossfire which requires graphics cards to be of the same model. API multi-GPU instead allows the API to intelligently split the workload among two or more completely different GPUs.[28] For example, integrated GPUs included on the CPU can be used in conjunction with a high-end dedicated GPU for a slight performance boost.

Development tools
GPU PerfStudio 3.6 supports Vulkan on Windows and Linux.[45]
OS components
The Vulkan Window System Interface (WSI) does for Vulkan what EGL does for OpenGL ES.[46] EGL is used by OpenGL ES programs to interface with the native platform windowing system. EGL handles context management, surface binding and rendering synchronization.
Compatibility
Initial specifications stated that Vulkan will work on hardware that currently supports OpenGL ES 3.1 or OpenGL 4.X and up.[47] As Vulkan support requires new graphics drivers, this does not necessarily imply that every existing device that supports OpenGL ES 3.1 or OpenGL 4.x will have Vulkan drivers available.
Android 7.0 Nougat supports Vulkan.[48] The software was released in August 2016.[49]
Vulkan support for iOS and macOS has not been announced by Apple, but at least one company provides a Vulkan implementation that runs on top of Metal on iOS and macOS devices.[50]

History
The Khronos Group began a project to create a next generation graphics API in July 2014 with a kickoff meeting at Valve Corporation.[64] At SIGGRAPH 2014, the project was publicly announced with a call for participants.[10]
According to the US Patent and Trademark Office, the trademark for Vulkan was filed on February 19, 2015.[65]
Vulkan was formally named and announced at Game Developers Conference 2015, although speculation and rumors centered around a new API existed beforehand and referred to it as "glNext".[66]
In early 2015, LunarG (funded by Valve) developed and showcased a Linux driver for Intel which enabled Vulkan compatibility on the HD 4000 series integrated graphics, despite the open source Mesa drivers not being fully compatible with OpenGL 4.0 until later that year.[67][68] There is still the possibility[69] of Sandy Bridge support, since it supports compute through Direct3D11.
On August 10, 2015, Google announced that future versions of Android would support Vulkan.[70] Android Nougat launched support for Vulkan on August 22, 2016.
On December 18, 2015, the Khronos Group announced that the 1.0 version of the Vulkan specification was nearly complete and would be released when conformant drivers were available.[12] The specification and the open-source Vulkan SDK were released on February 16, 2016.[6]
