With Blender 2.79, OpenCL support has improved and should be closer to parity with Blender’s CUDA capabilities. The OpenCL Cycles renderer has shorter render times by up to 50% in some cases, tiles are now seen updating while rendering, support for SSS and volume rendering, optimized transparent shadows, and various fixes.
The Portable Computing Language (POCL) has issued a new release of their open-source CPU-based OpenCL implementation. This new version of POCL continues relying upon LLVM and with this release adds support for LLVM/Clang 4.0 and 3.9.
Phoronix had a call with The Khronos Group president Neil Trevett to discuss some of their latest initiatives and the ongoing advancements to the Vulkan API, WebGL, SPIR-V, and more. Read about some of the highlights.
Phoronix has published benchmarks of 13 Kepler/Maxwell/Pascal NVIDIA GeForce graphics cards when testing Blender 2.78’s OpenCL renderer. Unfortunately, no AMD OpenCL benchmarks for Blender yet—the current open-source stack doesn’t work until ROCm OpenCL support comes into play and the AMDGPU-PRO stack wasn’t working for Blender OpenCL but was falling back to CPU rendering. Read the complete article.
The LibRetro crew is now working on a Vulkan renderer for a PlayStation One emulator. They have a Vulkan renderer working for the Beetle PSX, but the code hasn’t been published yet. In the past few days the LibRetro crew uploaded some YouTube videos showing the Vulkan-renderered PlayStation One emulator in action.
Fresh OpenCL compute benchmarks of 11 different GPUs when using the latest NVIDIA (370.28) and AMDGPU-PRO (16.30.3) Linux drivers on Ubuntu 16.04 LTS. The open-source (Clover-based stack) wasn’t used for any open-source AMD OpenCL testing due to its less than stellar state.
Phoronix benchmarking offers an initial look at the OpenGL / OpenCL / Vulkan Linux performance plus some thermal numbers for the GTX 1050 Mini. A follow-up article will include power consumption / performance-per-Watt metrics of the GTX 1050 / GTX 950 / GTX 750 / GTX 650 for a fun comparison of Pascal, Maxwell, and Kepler of these low/mid-range cards.
