The Khronos Group announced the availability of technical previews of the new Vulkan open standard API for high-efficiency access to graphics and compute on modern GPUs used in a wide variety of devices. This ground-up design, previously referred to as the Next Generation OpenGL Initiative, provides applications direct control over GPU acceleration for maximized performance and predictability, and uses Khronos’ new SPIR-V™ specification for shading language flexibility. Vulkan initial specifications and implementations are expected later this year and any company may participate in Vulkan’s ongoing development by joining Khronos.
Vulkan is a unified specification that minimizes driver overhead and enables multi-threaded GPU command preparation for optimal graphics and compute performance on diverse mobile, desktop, console and embedded platforms. Vulkan also provides the direct GPU control demanded by sophisticated game engines, middleware and applications with the cross vendor performance and functional portability resulting from simpler, more predictable drivers. The layered design of Vulkan enables multiple IHVs to plug into a common, extensible architecture for code validation, debugging and profiling during development without impacting production performance; this layering flexibility is expected to catalyze strong innovation in cross-vendor GPU tools.
