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.

Maybe they do it through a proxy app, part of the overall package of Windows' Telemetry?pookguy88 - Tuesday, October 17, 2023 - link
you didn't have a 13700k to test against?shabby - Tuesday, October 17, 2023 - link
Yup pity, that would show us what those 4 e-cores can actually do.TheinsanegamerN - Tuesday, October 17, 2023 - link
I mean they still dont have a GPU test bed going on 3 years post fire. I wouldnt expect much.nandnandnand - Wednesday, October 18, 2023 - link
I recommend everyone go to Tom's Hardware if they are missing something here. They'll have the reviews, decent ones IMO, and are owned by the same company as AnandKek.TheinsanegamerN - Thursday, October 19, 2023 - link
Tom's Hardware was caught shilling for Nvidia eons ago. They're another dinosaur of the tech space.Techspot, Techpowerup, and reviewers like gamers nexus are the new hotness.

Some motherboards will let you just set a power limit. I'd like to see a benchmark where the power limit is set to only the advertising number (125 W) and see what it can do with that constraint. 400+ watts just seems insane. My laptop is currently suffering terrible battery life because the CPU throttles up and gets hot and cooks the laptop because of exactly this Power Be Damned philosophy. I want a quiet desktop that isn't going to cook me if I'm sitting next to it, and isn't going to just cook the motherboard components and fail after a few years.I was expecting the new chip to be slightly more power efficient with a year of design tweaks and improvements. (And you'll note Intel wants you to think this because they kept the 125W marketing power usage on the box.) I am kinda baffled how Intel is executing so poorly. Nobody had a gun to their head forcing them to release this product. There's some deeply broken structural inertia in the organization to just keep pumping out products and not disrupting the flow of new model numbers. Somebody in Intel should have been screaming and said the plan wasn't working, rather than just keeping their head down to deliver a new model number for no reason.

If you want low power, get a ryzen. The 7800x3d tops out at just 50 watt.Performance loss, if anything like raptor lake (which this is) will be 15%+ down at 125 watt, more if they make heavy use of P cores.

Andandtech did this with the 13900k vs 7950X at different TDP/PPT. Basically the Ryzen at 65W TDP or 88W PPT was faster than Intel at 125W TDP. Once the Ryzen was set to 105W TDP or 142W PPT the Intel needed 253W TDP to be faster. In fact the scaling on the Ryzem dropped off quite quickly over 105W TDP.mode_13h - Wednesday, October 18, 2023 - link
