The Problem with the R9 285 and Ryzen APUs

Have you ever encountered a hardware problem that left you stumped? Well, I recently faced a baffling issue with the R9 285 graphics card while testing it with the new Ryzen 3 1200 processor. In this article, we'll explore the unexpected performance differences I discovered between using the APU and a dedicated standalone CPU. We'll also dive into the limitations of driver support for AMD APUs, particularly when paired with Radeon GPUs. So, let's jump right in and uncover the perplexing world of hardware testing and compatibility.

1. Introduction

When I set out to compare the performance of the R9 285 with the new Ryzen 3 1200, I expected similar results. However, I quickly noticed that the benchmarks were not aligning with my expectations, especially when using the APU. The performance gap between the two configurations was significant, raising questions about the compatibility and drivers for AMD APUs and Radeon GPUs. In this article, we'll dissect the issue, explore the benchmarks, and discuss the impact on gamers. Additionally, we'll look at potential solutions and workarounds for this intriguing problem.

2. The Problem with the R9 285

I had previously used the R9 285 in my main test rig with a Ryzen 7 system and obtained satisfactory results, even in non-CPU-bound games. However, when I tested the APU with the Horizon 3200G benchtable, something wasn't quite right. The performance was noticeably different from what I had experienced with the Ryzen 7 setup. To investigate further, I decided to compare the performance of the APU with a dedicated stand-alone CPU - the Ryzen 3 1200.

3. Testing with the Ryzen 3 1200

To understand the performance disparity, I ran a series of benchmarks using both the APU and the Ryzen 3 1200. Both processors were overclocked to 3.7 GHz across all four cores, ensuring a level playing field. The results were indeed fascinating and revealed a significant gap between the two configurations across various games and benchmarks.

4. Performance Comparison with the Ryzen 7

Before diving into the benchmark results, let's briefly compare the performance of the APU and the Ryzen 7. In games that aren't CPU bound, the APU's performance was underwhelming compared to the Ryzen 7 setup. This discrepancy raised concerns about the compatibility between AMD APUs and discrete graphics cards, particularly from AMD and NVIDIA.

5. Benchmarks and Results

Now, let's delve into the benchmark results and examine the performance differences in various games and scenarios. We'll explore three popular games: Assassin's Creed Origins, Far Cry 5, and Rise of the Tomb Raider. Additionally, we'll touch upon other tests that highlight the consistent gap between the APU and standalone CPU.

5.1 Assassin's Creed Origins

Assassin's Creed Origins, known for taxing even high-end systems, provided clear evidence of the performance disparity between the APU and the Ryzen 3 1200. While the APU struggled to maintain a decent average frame rate of 35 FPS, the Ryzen 3 1200 achieved an average of 45 FPS.

5.2 Far Cry 5

In Far Cry 5, the performance gap between the APU and the Ryzen 3 1200 was less pronounced. However, even a difference of 1 FPS in average and 1% low frame rates was noticeable, indicating a disparity in processing power.

5.3 Rise of the Tomb Raider

Moving on to Rise of the Tomb Raider, the performance gap continued to widen. Even at medium settings with FXAA enabled, the APU struggled to reach an average frame rate of 70 FPS, while the Ryzen 3 1200 comfortably achieved 73 FPS.

5.4 Other Tests

In our extensive testing, we observed a consistent difference of almost 10% on average between the APU and the Ryzen 3 1200. These unreproducible benchmarks raised concerns about the true potential of these APUs, as they essentially share the same architecture. The difference, if anything, should be negligible, but alas, it is not.

6. The Issue with Vega Graphics

As I delved into forums and sought answers from AMD, I discovered a crucial difference between the APU and standalone CPUs. The APU utilizes the Vega 8 GPU, which requires specific AMD drivers that are several revisions behind the Game-ready drivers available for standalone graphics cards. This driver disparity poses a significant problem for gamers who plan to pair an APU with a budget Radeon GPU.

7. Driver Support Limitations

One of the core issues lies in the lack of driver support from AMD for APUs paired with Radeon GPUs. While users with Intel CPUs can effortlessly download the latest GeForce drivers for their NVIDIA GPUs, AMD APU users are limited to the older drivers compatible with the cut-down Vega graphics. This limitation forces many users to consider alternative options, leaning toward the green team.

8. The Impact on Gamers

The driver support limitations ultimately affect gamers who choose to invest in AMD APUs with the intention of using a discrete GPU in the future. The inability to access the latest driver updates significantly hampers the performance potential of the integrated graphics, leading to a less-than-optimal gaming experience. This limitation may push many users to opt for Intel CPUs or turn to alternative solutions until AMD addresses the driver support issue.

9. Potential Solutions and Workarounds

While the current driver support limitations may discourage some users, it's essential to explore potential solutions and workarounds. One possible approach is to appeal to AMD to prioritize driver updates for APUs, bringing them in line with the latest game-ready drivers available for standalone GPUs. Additionally, users may experiment with alternative means of overcoming this limitation, such as tweaking BIOS settings or exploring third-party driver solutions, although these options come with their own risks and complexities.

10. Conclusion

In conclusion, the unexpected performance differences and driver support limitations between AMD APUs and Radeon GPUs pose challenges for users seeking an optimal gaming setup. The Ryzen 3 1200, although a capable processor, consistently outperforms the APU in benchmarks and games, leaving gamers dissatisfied. It is crucial for AMD to address this issue by providing up-to-date drivers for APUs, enabling users to harness the full potential of their hardware. Until then, users may need to consider alternative options or employ workarounds to optimize their gaming experience.

Highlights:

• The Ryzen 3 1200 outperforms the APU in benchmarks, revealing a significant performance gap.
• The limited driver support for APUs with Radeon GPUs creates compatibility issues and hampers gaming performance.
• Gamers may need to explore alternative solutions or workarounds until AMD addresses the driver support limitations.
