🎮 Ryzen 3900x vs. Intel 9900k: Which is the Better Streaming CPU?

Streaming has become an integral part of the gaming community, and having a powerful CPU is essential for a smooth and high-quality streaming experience. In this article, we will compare two popular CPUs, the Ryzen 3900x and the Intel 9900k, to determine which one is the better choice for streaming.

🎥 Streaming with NVENC vs. x264 Encoding

Before diving into the comparison, it's important to understand the two main encoding methods available: NVENC and x264. NVENC is a hardware-based encoding solution provided by Nvidia GPUs, while x264 is a software-based encoding solution that utilizes the CPU. Both methods have their pros and cons, which we will explore in detail.

📊 Benchmarking Encoding Presets in Streamlabs OBS

To analyze the performance and visual quality of the Ryzen 3900x and Intel 9900k, we will use Streamlabs OBS, a popular streaming software. We will test different encoding presets, ranging from fast to slow, and compare their impact on frame rate and visual quality.

4.1 Overview of Encoding Presets

Before delving into the benchmarks, let's understand the different encoding presets available. Faster presets offer lower visual quality but better streaming and gaming performance. Slower presets, on the other HAND, provide the best visual quality at the cost of performance. We will examine the trade-off between visual quality and performance for streaming purposes.

4.2 Visual Quality vs. Performance Trade-off

In the world of streaming, x264 fast is considered a decent viewing experience as long as the bitrate is sufficient. x264 medium is renowned for its exceptional quality, while x264 slow is reserved for high-end setups. However, most streamers would find x264 medium as the upper limit for high-quality streaming. We will evaluate the limitations of both CPUs when streaming at different presets.

4.3 Impact on Frame Rate

To measure the impact on frame rate while streaming, we will conduct benchmark tests in popular games such as Far Cry 5. By comparing the average frame rate of non-streaming gameplay to that of streaming, we can assess the performance of each CPU and determine if there are any significant differences.

📈 Frame Rate Analysis: Ryzen 3900x vs. Intel 9900k

In this section, we will analyze the frame rate performance of the Ryzen 3900x and Intel 9900k while streaming. By comparing their average frame rates and analyzing frame times, we can assess the smoothness of the stream and any potential stuttering or frame rate dips.

5.1 Far Cry 5 Performance Comparison

Using Far Cry 5 at 1080p as our benchmark, we will examine the frame rate impact of streaming on both CPUs. We will compare the performance of both CPUs using the x264 medium preset, as this is the deciding factor for many streamers. Additionally, we will evaluate the differences in performance between the CPUs when using the x264 very fast preset.

5.2 Frame Times and Smoothness

While average frame rate provides a baseline understanding, it does not Present the full picture. Frame times, which represent the interval between each frame, reveal the smoothness of the stream. We will analyze frame time spikes and stutters during gameplay and assess the impact on the viewer's experience.

👀 Viewer Experience: Lagged and Skipped Frames

To gauge the viewer's experience, we will examine how many frames are lagged, delayed, or skipped during the stream. Lagged frames result in jerky or Rubber banding movement, while skipped frames manifest as stutters. By comparing the stream performance of both CPUs at different encoding presets, we can determine which one provides a smoother and more enjoyable viewing experience.

6.1 Impact on Viewers' Experience

The Ryzen 3900x proves to be a reliable streaming CPU, delivering Flawless streams at x264 fast, medium, and even slow presets. On the other hand, the Intel 9900k struggles with the x264 slow preset, resulting in a stuttering mess. We will discuss the significance of different encoding presets and their impact on viewers' overall experience.

6.2 Stream Comparison at Different Presets

To provide additional context, we will compare the streaming performance of both CPUs at a lower resolution of 720p and 60fps. This allows us to evaluate the impact on frame rate and quality when using less demanding settings.

💡 Streaming on GPU vs. CPU: Pros and Cons

It is important to consider the pros and cons of streaming on the GPU versus the CPU before making a decision. Each method has its advantages and disadvantages, which can significantly impact the quality and performance of the stream.

7.1 Pros of GPU-based Streaming

Streaming on the GPU, particularly with the NVENC encoder, offers lower frame rate impact while gaming. The overall visual quality is excellent, and it maintains a stable 60fps stream. We will explore the benefits of GPU-based streaming and why it may be a suitable option for certain streamers.

7.2 Cons of GPU-based Streaming

Although GPU-based streaming has its benefits, it is not without its drawbacks. We may still encounter lagged or skipped frames occasionally, especially when additional sources like webcams are used. We will discuss the limitations of GPU-based streaming and its impact on stream fluidity.

7.3 Pros of CPU-based Streaming

Streaming on the CPU, particularly with the x264 encoder, allows for higher quality presets and more headroom for encoding additional sources. This method is preferable for those aiming for the highest visual quality and stability in the stream. We will elaborate on the advantages of CPU-based streaming and its impact on stream performance.

7.4 Cons of CPU-based Streaming

While CPU-based streaming provides excellent visual quality, it comes at the cost of frame rate performance. The CPU is responsible for both gaming and encoding, which can significantly impact the frame rate. We will discuss the limitations and potential stuttering issues that may arise when streaming on the CPU.

📝 Additional Considerations and Recommendations

In this section, we will address additional factors to consider when choosing a streaming CPU and provide recommendations based on your streaming needs.

8.1 Webcam Encoding and CPU Overload

When encoding additional sources like webcams, the CPU may become overwhelmed, leading to decreased stream fluidity and smoothness. This is a limitation of the NVENC encoder, as it struggles to encode multiple sources simultaneously. We will explore the impact of webcam encoding on stream quality and discuss potential solutions.

8.2 Streaming on Nvidia Turing GPUs

For users with Nvidia Turing GPUs, we will examine the advantages of using the NVENC encoder and streaming on these GPUs. With improved hardware encoding capabilities, streaming becomes more accessible and efficient. We will discuss the compatibility of different GPUs and recommend suitable options for streamers.

8.3 Choosing the Right CPU for Streaming

Based on our benchmarks and analysis, we will provide guidance on selecting the right CPU for streaming, depending on your desired encoding presets, visual quality requirements, and performance preferences. Whether you prioritize stability, frame rate, or high-quality presets, we will assist you in making an informed decision.

🏁 Conclusion

In conclusion, the Ryzen 3900x emerges as the better streaming CPU compared to the Intel 9900k. With its ability to stream at higher quality presets and lesser impact on frame rate, it is the preferred choice for streamers aiming for top-tier quality. However, for most streamers, x264 fast is more than sufficient, making either CPU a viable option. We encourage further discussion on the pros and cons of different encoding presets and the ultimate choice between the 3900x and 9900k for streaming purposes.
