Intel Core i9-14900K, Core i7-14700K and Core i5-14600K Review: Raptor Lake Refreshed
by Gavin Bonshor on October 17, 2023 9:00 AM ESTCPU 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 i9-14900K, 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
Note: As we are running with a completely refreshed CPU test suite, this means we are currently re-testing other processors for our data sets. These will be added to the below graphs as soon as we have more results, and these will also be added to our Bench database. Thanks for your understanding.
Moving onto encode and decode performance, there's not much difference between the Core i9-14900K and the Core i9-13900K. What's clear from our testing is that in encoding, Intel has the advantage over AMD with their flagship processors. The Core i7-14700K is also right up there in terms of performance, while the cheaper and less powerful Core i5-14600K trades blows with the AMD Ryzen 9 7900.

Well, I just built a new system with an Ryzen 9 7900x that I got on sale for $380 a couple weeks ago and have set at a 105w TDP. Looks like I have no regrets here either in performance or efficiency.Farfolomew - Tuesday, October 17, 2023 - link

So 13900k is better as you can get one for $450charlesg - Tuesday, October 17, 2023 - link
Re all the justified comments about excessive power draw, is this not only when using it at peak capacity?If you're using it at peak capacity, all the time, then I agree, you've got the wrong CPU. It's like driving your vehicle at or over 6000rpm all the time.
For everyone else who's using a compatible MB and prior gen intel cpu, who wants a drop in upgrade, this may be useful?
(I'm using an amd 5950x here, with no regrets. When I need the cores (and I do use them), it's there. The rest of the time, it just idles..)

I have 4 7950x machines where I encode using Handbrake SVT-AV1 almost 24/7. AT shows that the Intel is faster, but @ 2x the power consumption literally, AMD is still better. Besides my ambient rises at least 6-7c with the machines going 100%, I can't imagine how the 13900k/14900k will behave. Insane. Besides having all the machines going 100% with a 5000BTU AC it blows my circuit breaker, so I run the AC power with an extension from another room. I can't imagine how the 13900k/14900k will behave.PS: Before anyone says I should have gone for a 64+ core EPYC, it was still cheaper to build these 4 systems over a 64c Eypc, taking into consideration 12CH memory, server board, etc. and these run at least 5.1ghz all core over a Epyc at 3.5~ GHZ

The insane part of what you are doing is encoding in SW. Give up on some quality and run quicksync on an intel processor along with ARC GPU's for AV1.rUmX - Monday, October 23, 2023 - link
I did mess around with HW AV1 encoding on a Intel ARC A380. Quality was pretty good, but the file sizes are at least double (for GPU) for very very similar or even better quality (for SVT-AV1). I'm not doing live streaming, more like encoding for VOD, in this case filesize and bitrates are important as well as storage use. I'm using SSDs so smaller filesize = better. At that, the smaller the size, the more users I can serve at port speed.meacupla - Wednesday, October 18, 2023 - link
You can certainly drop it in, but it's not an upgrade going from 13th to 14th gen. It's a sidegrade at best. For the price, you would be better off upgrading to watercooling with a 280mm or 360mm radiator.SanX - Wednesday, October 18, 2023 - link
Ideally comparisons have to include previous gen competition too like AMD 5950x to convince people to upgradeSanX - Wednesday, October 18, 2023 - link
AMD has to start selling 32-core consumer chips based one their new 16-core chiplets versus older 8-core ones
