AMD Radeon Pro Duo Polaris: Retrospective and Relevance in 2025

Updated: April 2025

Introduction

The AMD Radeon Pro Duo Polaris, released in 2016, became a unique solution for professionals and enthusiasts, combining two GPUs on a single board. Despite its age, the card continues to attract interest due to its architecture and specialized capabilities. This article will examine how relevant it is in 2025 and who might still benefit from it.

Architecture and Key Features

Polaris Architecture: Based on a 14nm process technology. Two Polaris 10 chips (similar to those in the RX 480) are combined using CrossFire technology, allowing for parallel computing.

Unique Features:

- FidelityFX: AMD’s toolkit for enhancing sharpness and detail (for example, Contrast Adaptive Sharpening).

- LiquidVR: Optimization for VR applications (relevant for developers).

- No Ray Tracing: Unlike modern NVIDIA RTX 40/50 series, there is no hardware support for RT cores.

Professional Features: Support for ECC memory for error correction in calculations, as well as optimization for OpenCL and Vulkan APIs.

Memory: Type, Size, and Performance

- Memory Type: First-generation HBM (High Bandwidth Memory).

- Size: 32 GB (16 GB per GPU, but only 16 GB is accessible due to data duplication).

- Bandwidth: 512 GB/s thanks to a 4096-bit bus per chip.

Impact on Performance: HBM provides low latency, which is beneficial for rendering and scientific tasks. However, in 2025 games, the memory size does not compensate for the outdated architecture.

Gaming Performance: Numbers and Realities

2025 Testing Results (average FPS, High settings):

- Cyberpunk 2077: 28-35 FPS at 1080p, 15-20 FPS at 1440p.

- Starfield: 40-45 FPS at 1080p (without ray tracing).

- CS2: 120-140 FPS at 1440p.

Features:

- 4K Gaming: Not recommended — performance drops below 30 FPS in most titles.

- Ray Tracing: Not supported. Ray tracing effects require software emulation, resulting in performance loss.

Conclusion: This card is suitable for older games or projects with low requirements.

Professional Tasks: Editing, Rendering, and Computations

- Video Editing: In Adobe Premiere Pro (with GPU rendering), it handles 4K materials 1.5 times faster than the RTX 3060, thanks to optimization for OpenCL.

- 3D Rendering: In Blender (Cycles engine), rendering a scene takes 8 minutes compared to 10 minutes with the RTX 4060.

- Scientific Computations: OpenCL support allows the card to be used in MATLAB or for machine learning, but it lags behind NVIDIA in CUDA-optimized tasks.

Advice: For working with modern neural networks (Stable Diffusion, GPT), it’s better to choose cards with hardware support for AI accelerators.

Power Consumption and Thermal Management

- TDP: 250W.

- Cooling Recommendations:

- Case with 4-6 fans for ventilation.

- Liquid cooling is optional, but the stock cooler works well with regular cleaning.

- Power Supply: Minimum 750W with 80+ Gold certification.

Temperatures: Up to 85°C under load, which is acceptable, but the cooler noise can be annoying.

Comparison with Competitors

2025 Alternatives:

- NVIDIA RTX 4060 Ti (16 GB): Better gaming performance (+40% FPS), supports DLSS 3.5 and ray tracing. Price: $450.

- AMD Radeon RX 7600 XT: Higher energy efficiency, 120 FPS at 1080p. Price: $330.

- NVIDIA Quadro RTX A4000: Better optimization for professionals under CUDA. Price: $1200.

Conclusion: Pro Duo Polaris lags behind newer models in gaming but retains a niche in OpenCL tasks.

Practical Advice

- Power Supply: 750W and above.

- Compatibility: PCIe 3.0 x16, motherboards with sufficient space (card length — 30 cm).

- Drivers: Official support ceased in 2022, but the community releases patches (e.g., Amernime Zone).

- OS: It's best to use Windows 10 or Linux with open drivers.

Pros and Cons

Pros:

- High performance in OpenCL tasks.

- Large amount of HBM memory.

- Unique architecture for enthusiasts.

Cons:

- No support for ray tracing and DLSS/FSR 3.

- High power consumption.

- Limited driver support.

Final Conclusion: Who Should Consider the Radeon Pro Duo Polaris?

This card is suitable for:

1. Professionals working with OpenCL-optimized software (rendering, editing).

2. Enthusiasts building retro PCs or testing unconventional setups.

3. Budget studios needing high VRAM for 3D modeling.

Price in 2025: New units are nearly impossible to find, but leftovers are sold starting at $700.

Alternative: For most tasks, it’s better to choose modern AMD Radeon RX 8000 series or NVIDIA RTX 50 series cards.

If you are looking for a balance between exoticism and functionality, the Radeon Pro Duo Polaris deserves attention. But remember: this is a tool for specific scenarios, not a universal solution.

TMUs

Texture Mapping Units (TMUs) serve as components of the GPU, which are capable of rotating, scaling, and distorting binary images, and then placing them as textures onto any plane of a given 3D model. This process is called texture mapping.

Memory Bus

The memory bus width refers to the number of bits of data that the video memory can transfer within a single clock cycle. The larger the bus width, the greater the amount of data that can be transmitted instantaneously, making it one of the crucial parameters of video memory. The memory bandwidth is calculated as: Memory Bandwidth = Memory Frequency x Memory Bus Width / 8. Therefore, when the memory frequencies are similar, the memory bus width will determine the size of the memory bandwidth.

Bandwidth

Memory bandwidth refers to the data transfer rate between the graphics chip and the video memory. It is measured in bytes per second, and the formula to calculate it is: memory bandwidth = working frequency × memory bus width / 8 bits.

Pixel Rate

Pixel fill rate refers to the number of pixels a graphics processing unit (GPU) can render per second, measured in MPixels/s (million pixels per second) or GPixels/s (billion pixels per second). It is the most commonly used metric to evaluate the pixel processing performance of a graphics card.
