CPU Benchmark Performance: Encoding

One of the interesting elements of modern processors is encoding performance. This covers two main areas: encryption/decryption for secure data transfer and video transcoding from one video format to another.

In the encrypt/decrypt scenario, how data is transferred and by what mechanism is pertinent to on-the-fly encryption of sensitive data—a process that more modern devices are adopting to improve software security.

We've updated our list of encoding benchmarks for our 2024 CPU suite to include some of the most relevant and recent codecs, such as AV1 and HEVC. Not only this, but we have also WebP2 image encoding into the mix to show not only how the latest processors perform with these codecs but also to show discrepancies in performance throughout the different segments.

(3-1) WebP2 Image Encode: Quality 75, Compression Effort 7

(3-1b) WebP2 Image Encode: Quality 100, Lossless Compression

(3-2): SVT AV1 Encoding: Bosphorus 1080p, Fastest Preset

(3-2b): SVT AV1 Encoding: Bosphorus 4K, Fastest Preset

(3-3) SVT AV1 Encoding: Bosphorus 1080p, Mid-Speed Preset

(3-3b) SVT AV1 Encoding: Bosphorus 4K, Mid-Speed Preset

(3-4) Dav1d AV1 Benchmark, Summer Nature 4K

(3-5) SVT-HEVC Encoding: Bosphorus 1080p, Higher Quality

(3-5b) SVT-HEVC Encoding: Bosphorus 4K, Higher Quality

(3-6) SVT-VP9 Encoding: Bosphorus 1080p, Quality Optimized

(3-6b) SVT-VP9 Encoding: Bosphorus 4K, Quality Optimized

(3-7d) FFmpeg 6.0 Benchmark: libx265 Encode, Live Scenario

(3-8) FLAC Audio Encoding 1.4: WAV to FLAC

(3-9) 7-Zip 22.01 - Compression Rating

(3-9b) 7-Zip 22.01 - Decompression Rating

When it comes to encoding performance, there are as many wins for Zen 5 as there are losses. In our 7-Zip compression and decompression benchmark, Zen 5 doesn't really deliver compared to the other chips on test. In our FFMPEG encoding test, Zen 5 performs well, while in our FLAC audio encoding benchmark, the Ryzen 7 9700X only loses out to Intel's flagship Core i9-14900K, which is no loss in reality. In our AV1 encoding benchmarks, Zen 5 is competitive, but it doesn't give anything extra when compared to the competition.

    Thanks for the review. I personally would have liked to see a 7800X3D in the benchmarks. Also, I would have omitted 720p and replaced it with 1440p gaming benchmarks. 1080p is perfectly fine for a synthetic benchmark to see which CPU is faster overall and a lot of gamers run 1440p.

    Agreed. The 7800X3D should be very close in price to the 9700X so having both in the gaming charts would be pretty nice. Offhand I assume it will be a mix. For standard game the 9700x should have a small lead due to the Zen 5 improvements. For things that are cache sensitive that will make the 7800X3D more competitive or even faster.

    It doesn't make sense.
    The 7800X3D should be compared to the 9800X3D (which will come in a few months).

    It makes sense to compare the 7800X3D to the 9700X due to price, and I'm sure it'll be compared against the 9800X3D when it comes out too. These aren't mutually exclusive.
  • Klober - Wednesday, August 7, 2024 - link

    Seriously? Did none of you pay attention to the charts? There's clearly a 7800X3D in all but 2 of the charts on this page alone. I could maybe see an argument made for the 7900X3D (coincidentally, the CPU I have which I why I noted it's missing) but not the 7800X3D.
  • Trackster11230 - Wednesday, August 7, 2024 - link

    Yes, I see it in the charts, hence my comment about it making sense being in here. It's similar in price to the 9700X, so it makes sense to compare from that metric. What's so difficult to understand?

    I could make an argument too that an 8c/16t CPU makes more sense to compare to than the 7900X3D with 12c/24t.

    Seems odd that the gaming CPU is missing from the gaming results

    "Note: We are currently benchmarking more processors as we speak"

    I should read harder

    They said that they would re-test the Intel chips over the weekend in May. Did those updated benchmarks ever get done and published?

    The table says Quad Channel DDR support, I don't think that's true. It's 4 slots but it's dual channel, isn't it?
