Introduction

In this article, we will be reviewing the refreshed AMD Ryzen CPUs, specifically the R7 2700X and R7 2700. We obtained our CPUs from third-party sources and have been testing and iterating on our data over the past month. Today, we will be discussing the overclocking numbers, advantages of lower voltage, memory overclocking capabilities, streaming performance, gaming with GPU bottlenecks, rendering benchmarks, and power consumption. Let's dive in!

Refreshed AMD Ryzen CPUs

The refreshed AMD Ryzen CPUs, including the R7 2700X and R7 2700, offer improvements over their predecessors in terms of voltage required to maintain a target frequency. At the same frequency, the R7 2700X operates at significantly lower voltage compared to the previous R7 1700, resulting in lower power consumption. While the raw performance gains in terms of frequency and IPC are not substantial, the efficiency and voltage improvements make these new CPUs worth considering.

Overclocking Numbers

When it comes to overclocking, the Ryzen CPUs show interesting results. The 2700X performed stably at 4.2 GHz with a voltage input of 1.175V and a power consumption of 129 watts in Blender. On the other HAND, the overclocked 1700 required a voltage input of 1.425V and consumed 201 watts, indicating a 70-watt difference. This showcases the lower voltage and power consumption of the newer CPUs.

Advantages of Lower Voltage

The primary advantage of lower voltage is the reduction in power consumption while maintaining the same frequency. This is especially evident in tasks like rendering and multi-threaded applications. The Ryzen CPUs offer better efficiency and improved clock stability, resulting in more consistent performance compared to their predecessors.

Memory Overclocking

Memory overclocking capabilities have seen significant improvements with the new Ryzen CPUs. Our testing showed that both the X470 and X370 platforms were capable of handling DDR4-3600 XMP, with the X470 board allowing for further improvements. However, the scaling in performance between different memory frequencies is Incremental, and the difference between DDR4-3200 and DDR4-3600 may not be significant for most users. It is recommended to opt for DDR4-3200 with tighter timings for better performance and value.

Streaming Performance

When it comes to streaming, both the R7 2700X and the i7-8700K are capable of delivering high-quality streams. However, the 2700X offers a slight advantage in terms of efficiency and headroom for increasing stream quality. The Intel CPUs may outperform in terms of raw framerate on the streamer's side, but the 2700X provides a better viewer experience with improved stream quality.

GPU Bottlenecks in Gaming

In gaming benchmarks, both the 2700X and i7-8700K perform well. However, GPU bottlenecks often hinder further scalability in performance. The 8700K shows a lead in raw FPS in games like Dota 2, while the 2700X offers better performance when it comes to encoding and stream quality. Overall, the choice between the two CPUs depends on the specific gaming and streaming requirements of the user.

Rendering Benchmarks

The new Ryzen CPUs exhibit impressive performance in rendering benchmarks. The 2700X, when overclocked to 4.2 GHz, offers similar performance to the overclocked 1700X and even outperforms the Intel i7-8700K at 5 GHz. The improved efficiency and reduced time requirements make the Ryzen CPUs a great choice for CPU-intensive tasks such as rendering.

Power Consumption

Power consumption varies between the Ryzen CPUs and Intel CPUs, and the TDP values should not be directly compared. The Ryzen CPUs, especially the 2700X, have shown lower power consumption compared to their predecessors. However, it is important to consider the cooling requirements for sustained performance at high frequencies.

Conclusion

In conclusion, the refreshed AMD Ryzen CPUs offer improved efficiency, lower power consumption, and great performance in various tasks. Overclocking is not necessary for the X series CPUs, but can be beneficial for the non-X series. Memory overclocking is incremental in terms of performance gains, and it is recommended to opt for DDR4-3200 with tighter timings. Streaming performance is excellent on both the Ryzen and Intel CPUs, with the 2700X offering better stream quality. Overall, the choice between Ryzen and Intel CPUs depends on specific requirements and preferences.
