Intel Core i9-14900K, Core i7-14700K and Core i5-14600K Review: Raptor Lake Refreshed

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.

This power consumption / heat output is insane… this is putting their 90nm Netburst Prescott / Pentium D Smithfield days to shame. Remember when Apple left IBM/Motorola alliance? Power architecture power consumption going thru the roof, and intel JUST pivoted back to PIII/Pentium M-based Core arch. No wonder why Apple dumped Intel, they called what they were seeing really early on. Arm for windows/linux desktop needs to get more serious, apple's desktop arm is proving nearly as powerful using a fraction of the power draw. Windows is ready, and can even run non-arm code too.herozeros - Tuesday, October 17, 2023 - link
My AMD AM5 would like a word with you …FLEXOBENDER - Tuesday, October 17, 2023 - link
What point are you trying to make, that you have no clue how thermodynamics work?This 14900K manages to pull 430 watt peak. 430. 0.43 kilowatt. one CPU.
It is still beat by a 80 watt peak 7800x3d. What is your point?

I think the point was that you don't have to abandon x86 for ARM to achieve good efficiency, just Intel.The Von Matrices - Thursday, October 19, 2023 - link
People remember Netburst CPUs as being absurdly power hungry, but they forget that even the most power-hungry Netburst CPUs still only had a TDP of 130W. Today that would be considered a normal or even a low TDP for a flagship CPU. It's actually understating the TDP if you compare it to a Netburst CPU.GeoffreyA - Friday, October 20, 2023 - link
And didn't Cedar Mill further drop that to a 65W TDP?GeoffreyA - Friday, October 20, 2023 - link
Possibly, ISA is just a small piece of the power puzzle, and the rest of the design is what's carrying the weight.An interesting article:

Did i miss something or are there no temperatures shown? Because 428W shouldn't be on the low side and demands a good Cooling Solution.Gastec - Tuesday, October 17, 2023 - link
Just one question: do these AI "tools" connect to the Internet, after they "measure specific system characteristics, including telemetry from integrated sensors", to send that data to those Intel servers that are in the "cloud"?TheinsanegamerN - Tuesday, October 17, 2023 - link
Of course they do. Even if they say they dont.
