AMD Publishes Polaris Patches To Linux Kernel With Baffin & Ellesmere PCI IDs
AMD Polaris is built using a 14nm FinFET fabrication process. The fourth generation GCN architecture for new Radeon GPUs brings a new memory controller, new multimedia cores, and a new geometry processor. Moreover, Polaris chips will support both HDMI 2.0a and DisplayPort 1.3, and are equally capable of encoding and decoding H.265 video up to 4K resolution.

Red matter and green blood; Vulkan runs on Linux
Last week AMD released a new GPU-PRO Beta driver stack and this Monday, NVIDIA released the 364.12 beta driver, both of which support Vulkan and meant that Phoronix had a lot of work to do. Up for testing were the GTX 950, 960, 970, 980, and 980 Ti as well as the R9 Fury, 290 and 285. Logically, they used the Talos Principal test, their results compare not only the cards but also the performance delta between OpenGL and Vulkan and finished up with several OpenGL benchmarks to see if there were any performance improvements from the new drivers. The results look good for Vulkan as it beats OpenGL across the board as you can see in the review.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
