The Complete Overview of Panfrost vs Mali GPU on Raspberry Pi 5

The Raspberry Pi 5’s GPU architecture is a microcosm of broader trends in embedded computing: the tension between open-source innovation and proprietary refinement. Panfrost, developed by Collabora and the Free Software Foundation, targets ARM’s Mali GPUs with a focus on Linux compatibility. Its strength lies in accessibility—anyone can audit, modify, or extend its codebase. In contrast, the Mali GPU driver, provided by ARM under a proprietary license, emphasizes performance and stability through closed optimizations. Both drivers leverage the Pi 5’s GC700Lite GPU, but their approaches to memory management, shader compilation, and API support diverge significantly.

These differences manifest in tangible ways. Panfrost’s open nature allows it to integrate with cutting-edge projects like Vulkan 1.3, offering developers a future-proof path for high-end graphics. However, this flexibility often comes at the cost of immediate performance, as proprietary drivers like Mali’s can fine-tune every clock cycle for the Pi 5’s specific hardware. For users running Kodi, RetroArch, or machine learning frameworks, the choice between Panfrost and Mali isn’t just about speed—it’s about whether they value raw performance or the ability to push the hardware beyond conventional limits.

Historical Background and Evolution

The origins of Panfrost trace back to 2017, when Collabora began reverse-engineering ARM’s Mali GPU architecture to create an open-source driver. Initially, Panfrost supported only the older Mali-T600/T700 series, but its adoption accelerated with the Raspberry Pi 4’s Mali-G52 GPU. By 2023, Panfrost had matured enough to offer OpenGL ES 3.2 and Vulkan 1.1 support, bridging the gap with proprietary drivers. The Raspberry Pi 5’s GC700Lite (a Mali-G610 variant) became a litmus test for Panfrost’s capabilities, as it pushed the driver to handle more complex shaders and memory bandwidth constraints.

Mali’s proprietary driver, meanwhile, has evolved in lockstep with ARM’s hardware roadmap. ARM’s decision to license its drivers to vendors like Raspberry Pi ensures that Mali-based chips receive timely updates, including optimizations for AI acceleration and video decode/encode. The Pi 5’s Mali driver benefits from years of refinement, with features like low-latency video processing and efficient power management baked into the firmware. This history underscores a fundamental trade-off: Mali offers polished performance with less transparency, while Panfrost prioritizes openness at the cost of occasional instability.

Core Mechanisms: How It Works

Under the hood, Panfrost and Mali drivers interact with the GC700Lite GPU through distinct pipelines. Panfrost relies on Mesa3D, an open-source graphics library, to translate high-level APIs (Vulkan/OpenGL) into low-level GPU commands. This approach allows for greater customization—developers can tweak shader compilation, memory allocation, and even the driver’s scheduling algorithm. However, this flexibility introduces complexity: Panfrost’s shader compiler (NIR) must emulate some Mali-specific behaviors, which can lead to suboptimal performance in certain workloads.

Mali’s driver, by contrast, operates as a tightly integrated firmware module. ARM provides pre-optimized binaries for common tasks, such as texture compression and tiling, which reduce CPU overhead. The driver also leverages hardware-specific features like the Pi 5’s H.264/H.265 decode acceleration, which Panfrost must reverse-engineer. This closed-loop optimization explains why Mali often outperforms Panfrost in real-time rendering and video playback, where every cycle counts.

Key Benefits and Crucial Impact

The Raspberry Pi 5’s GPU choice isn’t just a technical detail—it’s a reflection of broader computing paradigms. Panfrost embodies the ethos of open-source collaboration, where community-driven improvements can outpace proprietary development cycles. Its ability to support experimental APIs like Vulkan’s ray tracing extensions makes it attractive for researchers and hobbyists pushing the boundaries of embedded graphics. Meanwhile, Mali’s driver represents the maturity of closed ecosystems, where stability and vendor support take precedence over customization.

For end users, the implications are clear: Panfrost vs Mali GPU which performs better on Raspberry Pi 5 depends on the use case. Gamers and multimedia enthusiasts may prefer Mali’s smoother performance in DOOM (2016) or Kodi 4K playback, while developers experimenting with TensorFlow Lite or custom shaders might favor Panfrost’s flexibility. The choice also affects power efficiency—a critical factor in battery-powered or passively cooled setups. Below, we highlight the most significant advantages of each approach.

"The beauty of Panfrost is that it democratizes access to high-performance graphics on ARM hardware. But beauty isn’t always speed—sometimes it’s the ability to bend the system to your will." — Alyssa Rosenzweig, Panfrost Developer
