AMD Radeon R9 M385: Review of an Outdated Mobile Graphics Card

April 2025

Despite the rapid advancement of technology, some users still encounter laptops equipped with the AMD Radeon R9 M385. This mobile graphics card, released in the mid-2010s, continues to serve in budget devices. Let's explore what it can do in 2025 and who it is suitable for.


Architecture and Key Features

GCN 3rd Generation Architecture

The Radeon R9 M385 is based on the 3rd generation Graphics Core Next (GCN) architecture, which at the time provided a good balance between performance and energy efficiency. However, by modern standards, this technology is outdated: it lacks hardware ray tracing support, and the compute units are not optimized for AI tasks.

28 nm Process Technology

The card is manufactured using a 28 nm process, which negatively impacts power consumption and heat generation compared to modern 5 nm and 6 nm chips.

Unique Features

Notable AMD technologies include support for FreeSync to eliminate screen tearing. However, solutions such as FidelityFX Super Resolution (FSR) or FidelityFX CAS are unavailable as they were introduced later. NVIDIA technologies, including DLSS and RTX, are also not supported.


Memory: Type, Capacity, and Impact on Performance

GDDR5 and Modest Specs

The graphics card comes with 4 GB of GDDR5 memory and a 128-bit bus. The bandwidth is 96 GB/s (with an effective clock of 6000 MHz). This is sufficient for games from 2015 to 2018 at medium settings, but in modern titles, the memory falls short even for high-quality textures.

Limitations in 2025

In games with detailed open worlds, like Cyberpunk 2077 or Starfield, the memory capacity becomes a bottleneck. Graphics settings must be reduced to a minimum, and resolution lowered to 720p or 900p.


Gaming Performance

1080p: Only Old Titles

At Full HD resolution (1920×1080), the R9 M385 shows modest results:

- The Witcher 3: Wild Hunt — 25–35 FPS on medium settings;

- Overwatch — 50–60 FPS on high settings;

- Fortnite — 40–50 FPS on low settings (with complex effects disabled).

1440p and 4K: Not Recommended

Even at QHD (2560×1440), the frame rate drops below 30 FPS. 4K mode is unplayable.

Ray Tracing: Absent

Hardware ray tracing is not supported. Software methods (e.g., through Proton on Linux) yield extremely low performance.


Professional Tasks

Video Editing and 3D Modeling

The card can handle basic tasks in software like Adobe Premiere Pro or Blender, but only with small projects. Rendering complex scenes takes significantly longer than on modern GPUs.

OpenCL and Scientific Calculations

OpenCL support allows the R9 M385 to be used for simple computations; however, the absence of specialized cores (like CUDA in NVIDIA) limits its application in science and machine learning.


Power Consumption and Heat Generation

TDP 50–75 Watts

The model consumes relatively little power, which is typical for mobile solutions. However, due to the outdated process technology, the laptop's cooling system may operate at high speeds under load, generating noise.

Cooling Recommendations

- Regularly clean the ventilation grilles of dust;

- Use cooling pads during long gaming sessions;

- Avoid overclocking as the performance headroom is minimal.


Comparison with Competitors

NVIDIA GeForce GTX 950M/960M

The R9 M385 is on par with the GTX 950M but lags behind the GTX 960M by 15–20% in games. NVIDIA's advantages include more stable drivers and support for technologies like ShadowPlay.

Modern Alternatives

In 2025, integrated GPUs like the Ryzen 5 8640U or Intel Core Ultra 5 134U fall within a similar price range (around $100–150) and demonstrate comparable performance with lower power consumption.


Practical Tips

Power Supply and Compatibility

- Laptops with the R9 M385 typically come with power supplies rated at 90–120 Watts. When replacing the PSU, choose original models;

- The card is compatible with PCIe 3.0, but may not work correctly on modern motherboards due to outdated firmware.

Drivers

AMD officially ceased support for the R9 M385 in 2022. Universal drivers can be used for Windows 11/12, but stability is not guaranteed.


Pros and Cons

Pros:

- Low price on the secondary market (around $50–80);

- Support for FreeSync;

- Sufficient for office tasks and older games.

Cons:

- No support for modern technologies (FSR, ray tracing);

- Weak drivers;

- High noise under load.


Final Verdict: Who is the R9 M385 Suitable For?

This graphics card is a choice for those who:

1. Use an old laptop and do not plan to upgrade;

2. Play less demanding titles (indie games, classics from the 2010s);

3. Need a budget solution for basic tasks (web surfing, office programs).

In 2025, it is hard to recommend the R9 M385 for purchase. If your budget is limited to $100–200, consider laptops with integrated graphics from Ryzen or Intel Xe — they will offer better performance and support for new technologies.


Conclusion

The AMD Radeon R9 M385 is an example of a "workhorse" from the past decade. It still has some capabilities, but time has taken its toll. For modern tasks, it is advisable to consider newer solutions, even if they require a slightly larger investment.

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.
