compute shaders that harness GPU parallelism for advanced computation such as image, volume, and geometry processing within the context of the graphics pipeline New functionality in the OpenGL 4.3 specification includes:
The full specification is available for immediate download at Twenty years since the release of the original OpenGL 1.0, the new OpenGL 4.3 specification has been defined by the OpenGL ARB (Architecture Review Board) working group at Khronos, and includes the GLSL 4.30 update to the OpenGL Shading Language. The OpenGL 4.3 specification contains new features that extend functionality available to developers and enables increased application performance. OpenGL 4.3 integrates developer feedback and continues the rapid evolution of this royalty-free specification while maintaining full backwards compatibility, enabling applications to incrementally use new features while portably accessing state-of-the-art graphics processing unit (GPU) functionality across diverse operating systems and platforms. There's also been the mainlining of the RADV Radeon Vulkan driver too that works on the RX 470.The Khronos Group today announced the immediate release of the OpenGL 4.3 specification, bringing the very latest graphics functionality to the most advanced and widely adopted cross-platform 2D and 3D graphics API (application programming interface). Besides the performance, back in August this open-source driver stack only supported OpenGL 4.3 while now it has all GL 4.4/4.5 extensions although it doesn't formally advertise the new versions yet pending conformance.
Various OpenGL benchmarks were compared to the original numbers on the same Xeon E3-1280 v5 Skylake system with MSI C236A WORKSTATION motherboard, and 16GB of RAM. What we have to look at this Sunday is the open-source driver stack from early August on the Sapphire Nitro+ RX 470 OC with Linux 4.8 and Mesa 12.1-dev compared to the state today with Mesa 13.1-dev + LLVM 4.0 SVN Git and Linux 4.8.4 stable (since only recently the Linux 4.9 AMDGPU fallout has been getting cleaned up). If you've been wondering how the AMDGPU+RadeonSI open-source driver stack has evolved since the hardware publicly launched, I ran some fresh benchmarks this weekend comparing my current driver numbers to that of my original Radeon RX 470 Linux review.
