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 by which more modern devices are leaning towards for improving 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, HEVC, and VP9. Not only this, but we have also included FLAC audio encoding as well as 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.

We are using DDR5 memory on the Core i9-14900KS, as well as the other Intel 14th Gen Core series processors including the Core i9-14900K, the Core i7-14700K, Core i5-14600K, and Intel's 13th Gen at the relative JEDEC settings. The same methodology is also used for the AMD Ryzen 7000 series and Intel's 12th Gen (Alder Lake) processors. Below are the settings we have used for each platform:

  • DDR5-5600B CL46 - Intel 14th & 13th Gen
  • DDR5-5200 CL44 - Ryzen 7000
  • DDR5-4800 (B) CL40 - Intel 12th Gen

(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

(3-7) FFmpeg 6.0 Benchmark: libx264 Encode, Live Scenario

(3-7b) FFmpeg 6.0 Benchmark: libx264 Encode, Live Scenario

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

(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

Onto encoding, the Core i9-14900KS and its higher core frequencies typically make a little difference in performance, especially compared directly to the Core i9-14900K. Again, much of the gains in performance, where there are any, are marginal at best.

    They take a light approach to comment removal. Things would have to devolve into petty squabbling or delve into topics like AT's loss of web traffic or credibility so its not like they censor with a heavy hand. It's just to protect Future LLC's financial interests and how it appears to readers. Calm down please. Reply

    Instable means unstable?! NoooOOOoo! Reply

    Suffering instability while being unstable...yikes Reply

    Thanks Gavin. Enjoyable read. Pretty steep CPU+cooler investment, considering a $20ish Thermalright air cooler can cool an i5-14600K just fine.

    Autocorrect may have nipped this phrase: "...decide the IHS from the chip..."

    I appreciate your comment.

    Also, thank you for spotting that. My apologies! It has now been fixed :)

    I would so love for Anandtech to do another of their IPC-focused articles at this moment between AMD and Intel. Take the Core i9 14900K (or KS, don't matter), disable all the E-cores, and set all the P-cores at the same 4.0GHz. From AMD, use both the Ryzen 7 7800X and 7800X3D, and do the same: set all cores to 4.0GHz. Then take those three setups (Zen 4, Zen 4+X3D, Raptor Lake Refresh) through the full benchmark runs. Everyone on the same amount of cores, same frequency. Reply

    Can we see the v/f curve from the VID of the chip you have for testing?
    Specifically what are the VID voltages at 6.2 and 5.9? At 6.2 they can vary from just below 1.4V (golden sample) to over 1.5V (really bad).

    Why is it Anandtech is posting reviews of a CPU thats been out a while now... Reply

    They probably finally got enough ad revenue to buy one since no one samples them anything anymore it seems. Reply
