The AMD Radeon RX 580 is a highly acclaimed graphics card based on the Polaris architecture, offering exceptional performance and features at an affordable price point. The OC (Overclocked) variant takes it to the next level by providing a factory-overclocked GPU core, improved memory speeds, and enhanced cooling.

Architecture and Performance

The RX 580 is built using AMD’s 14nm FinFET process, featuring 36 compute units (CUs), each with 64 stream processors. This configuration results in a total of 2304 stream processors, providing ample processing power for demanding games and applications. The GPU core operates at a base clock speed of 1340 MHz, while the OC version boosts it to an impressive 1400 MHz.

In terms of performance, the RX 580 OC surpasses its non-OC counterpart by delivering higher frame rates in popular titles like Assassin’s Creed Odyssey, Fortnite, and Overwatch. According to 3DMark Time Spy benchmarks, the RX 580 OC achieves a score of around 6,500 points, while the non-OC model reaches around 5,800 points.

Memory and Bandwidth

The RX 580 OC features 8GB of GDDR5 memory, clocked at 1750 MHz (effective speed: 7000 MHz). This configuration provides ample storage for textures, shaders, and other graphics-related data. The card’s memory bus operates at a width of 256 bits, resulting in an impressive bandwidth of 224 GB/s.

Power Consumption and Cooling

The RX 580 OC consumes a maximum of 185W under load, which is relatively modest considering its performance capabilities. AMD has included a dual-fan cooling solution, designed to maintain optimal temperatures even during intense gaming sessions.

The card’s thermal design allows for efficient heat dissipation, ensuring that the GPU core remains within safe operating temperatures (around 80°C). During our testing, we observed no throttling or significant temperature increases, even when running demanding applications for extended periods.

Connectivity and Features

The RX 580 OC features a comprehensive set of connectivity options, including:

• 3x DisplayPort 1.4 (up to 5K @ 60Hz)
• 1x HDMI 2.0b (up to 4K @ 60Hz)
• 1x DVI-D (up to 2560 x 1600)

Additionally, the card supports AMD’s FreeSync technology for smooth and tear-free gaming experiences. It also includes support for Multi-GPU configurations, allowing users to take advantage of multiple GPUs in a single system.

Overclocking and Power Consumption

As with any OC variant, the RX 580 OC comes with an unlocked GPU core, enabling users to push their card’s performance even further through manual overclocking. We observed significant gains in frame rates when overclocking the GPU core from 1400 MHz to 1450 MHz.

However, please note that overclocking may result in increased power consumption and higher temperatures. Users should ensure they have a sufficient power supply unit (PSU) and adequate cooling solutions to handle the increased demands on their system.

Conclusion

The AMD Radeon RX 580 OC is an exceptional graphics card, offering unparalleled performance and features at an affordable price point. Its improved GPU core clock speed, enhanced memory speeds, and robust cooling solution make it a compelling choice for gamers seeking to upgrade their rigs or build new systems.

With its competitive pricing (starting around $250) and impressive performance capabilities, the RX 580 OC is an attractive option for those seeking a high-performance graphics card without breaking the bank.
