SiFive recently sent over a review sample of the much anticipated HiFive Premier P550 developer board, their newest RISC-V creation featuring four RISC-V cores, Imagination AXM-8-256 integrated GPU, Gigabit Ethernet, PCIe x16 slot, and 16GB or 32GB of RAM. The HiFive Premier P550 is a modern RISC-V developer board capable of desktop uses, developer build boxes, and similar with pricing starting out at $399 USD. Here is a look at the SiFive HiFive Premier P550 as well as comparison benchmarks of this RISC-V board to the popular Raspberry Pi single board computers.

Wim Taymans of Red Hat today released PipeWire 1.4 as the newest major update for this leading open-source software to replace PulseAudio, JACK, and other solutions on the modern Linux desktop for managing audio and video streams in a very excellent way...

With the release of Blender 4.3 last November an experimental Vulkan back-end was added and it continues to be improved upon for modernizing this 3D creation suite for digital artists and serving a variety of other purposes. The upcoming Blender 4.4 release will further refine the Vulkan support while later in the year it should be reaching production readiness...

The FreeBSD Foundation paired with resources committed by AMD, Dell, and Framework are working to improve FreeBSD laptop support. In recent months there have been FreeBSD development efforts to improve the power management support with modern laptops as well as a strong focus on enhancing the WiFi driver support. A status update was issued yesterday for highlighting the latest FreeBSD laptops efforts...

Last week AMD formally announced the Radeon RX 9070 series graphics cards that will begin shipping tomorrow at $549 for the Radeon RX 9070 and $599 for the RX 9070 XT. Today the review embargo is lifted so we can now share Linux performance benchmarks and more details on the open-source Linux driver support for these first AMD RDNA4 graphics cards.

In addition to the Radeon RX 9070 series Linux gaming/graphics benchmarks with today's embargo lift, I've also spent some time working on some GPU compute benchmarks for these first RDNA4 graphics cards. Here is a look at some initial GPU compute benchmarks of the Radeon RX 9070 and Radeon RX 9070 XT graphics cards, mostly on cross-vendor OpenCL benchmarks, and a few words on the GPU compute stack support for the Radeon RX 9070.

In addition to Vulkan-powered AI / machine learning talks at last month's Vulkanised 2025 conference, another interesting topic at this annual Vulkan developer conference was around improving the Vulkan API and making it easier for new developers and maximizing the potential with new GPU hardware...

The FreeDesktop.org GitLab instance that is heavily relied upon for the development of the Mesa graphics drivers, Wayland, and many other Linux desktop projects will be down for up to one week later this month due to its cloud migration...

Linux already supports a number of XP-Pen drawing tablets while the upcoming Linux 6.15 kernel is set to include support for another one: the XP-Pen Artist Pro 19. This XP-Pen Artist Pro 19 is a big, 4K resolution display drawing tablet that retails for nearly $800 USD and features dual stylus, 16K pressure levels, and a nice display for this 19-inch drawing surface...

V druhé části obsáhlého článku se dozvíte něco o tom, čím jsem nahradil svou letitou zrcadlovku Pentax a jak vlastně vypadal upgrade. Co vyhrálo, jaké parametry jsou pro mě důležité? Co jsem koupil?

Pravidelná sonda do světa software. Podíváme se na platformu pro monitorování a správu clusterů Apache Cassandra, vyzkoušíme správce databází založených na SQLite a nakonec budeme analyzovat binární soubory.

Released last year shortly after the EPYC 9005 "Turin" processor launch was ZenDNN 5.0 for Zen 5 optimized CPU inferencing with the likes of PyTorch and TensorFlow. ZenDNN 5.0 delivers up to a 400% performance uplift according to AMD engineers. Out today is ZenDNN 5.0.1 with further optimizations, particularly around recommendation engines and large language models (LLMs)...
