AMD Ryzen 7 5700X: A much more efficient CPU than the 5800X

Photos 2/2: Affinity Photo, Topaz Labs AI Apps, ZPS X, ...

At the eleventh hour, but still. The long-awaited Ryzen 7 5700X is here. However, we won’t be writing about the successor to the Ryzen 7 3700X as a significantly cheaper alternative to the Ryzen 7 5800X. The new octa-core Ryzen 7 5700X is primarily more economical compared to the higher-end model. Its power draw is just half in some tasks, which means that temperatures are also significantly lower.

Affinity Photo (benchmark)

Test environment: built-in benchmark.





Topaz Labs AI apps

Topaz DeNoise AI, Gigapixel AI and Sharpen AI. These single-purpose applications are used for restoration of low-quality photos. Whether it is high noise (caused by higher ISO), raster level (typically after cropping) or when something needs extra focus. The AI performance is always used.

Test settings for Topaz Labs applications. DeNoise AI, Gigapixel AI and Sharpen AI, left to right. Each application has one of the three windows

Test environment: As part of batch editing, 42 photos with a lower resolution of 1920 × 1280 px are processed, with the settings from the images above. DeNoise AI is in version 3.1.2, Gigapixel in 5.5.2 and Sharpen AI in 3.1.2.



The processor is used for acceleration (and high RAM allocation), but you can also switch to the GPU

XnViewMP

Test environment: XnViewMP is finally a photo-editor for which you don’t have to pay. At the same time, it uses hardware very efficiently. In order to achieve more reasonable comparison times, we had to create an archive of up to 1024 photos, where we reduce the original resolution of 5472 × 3648 px to 1980 × 1280 px and filters with automatic contrast enhancement and noise reduction are also being applied during this process. We use 64-bit portable version 0.98.4.

Zoner Photo Studio X

Test environment: In Zoner Photo Studio X we convert 42 .CR2 (RAW Canon) photos to JPEG while keeping the original resolution (5472 × 3648 px) at the lowest possible compression, with the ZPS X profile ”high quality for archival”.

  1. Nice review, especially the details in the Premiere Pro part.
    However, there are some questionable results, namely the “4K H.264, 2× Forward Live Playback [avg. fps] – higher is better” and others, where the 5700X is last by a wide margin. Have you redone the tests (or ran similar tests) to see if this was just an outlier? It would have been nice to at least have a comment on such a weird result…

    1. Thanks for your comment. The explanation is in the text of the final chapter, and I also explain this behavior in the Ryzen 5 5600 test, which performs better, but is still the second processor from the bottom in the charts. The point is that 4K H264 live playback is a single-threaded task in Premiere Pro, but because of the utilization of the other cores by other application processes, the frequencies are only at the all-core boost level. These are pretty conservative for the Ryzen 7 5700X from today’s perspective (the 5600 is 300 MHz faster here, hence the higher fps), plus Zen 3 doesn’t handle 4K H.264 well overall, and better results are achieved with both 4K ProRes 222 and 4K RED.

      1. Thanks for replying. I read the explanation at the end of the review, but “the 500 MHz difference” still didn’t seem to be enough of a reason for such a big difference. Something else must be at play here, though I am also not sure of what it may be.

  2. why in total war troy 5600x shows more fps than 5700x? after all, this strategy loads the processor well and, according to the logic, the 16th nuclear one should have come out with a large margin from the 12th nuclear one !! ps: I myself am a fan of total war warhammer 1/2/3 and have a 5600x processor, but yesterday I ordered a new 5700x processor

    1. The reason for this is apparently very simple. The 6 cores/12 threads of the R5 5600X processor do not represent a bottleneck for TWST, and higher clock speeds are decisive for higher performance. And those the R7 5700X achieves are lower.

  3. Great review, really liking the detailed analysis. I saw a comment on reddit that linked to this review stating that if the 5800x was limited to 65w TDP, the performance efficiency might be similar to the 5700x. Have you thought about testing this out?

    1. Thanks for your comment. Due to a lot of time pressure, we probably won’t be testing the R7 5800X with reduced power draw anymore. But if we see a similar situation with the Ryzen 7000 and something like the R7 6700(X) and R7 6800, we’ll definitely take a look at it. However, it’s good to note that such analyses require multiple CPU samples to operate outside of their specs. The fact that a single 5800X sample would be limited to 65W and the performance was higher than the R7 5700X@TDP/65W doesn’t mean anything relevant yet.

      It’s similar to overclocking. Based on one sample, it is not possible to generalize that this or that frequency will be achieved at xyz W of power draw. You always have to evaluate it based on multiple samples of processors and sooner or later we will get to that and once we have more of them (those test samples) we will for sure look at the variance of the measured values across the samples as well.
