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.

AMD has not been generous with multi-threading at the entry level, e.g. 7600/7800X.I don't agree that they have to start selling 32-cores soon. They have a few ways to address multi-threading with Zen 5 or Zen 6. The easiest one for Zen 5 would be to make a 24-core with an 8+16 configuration. But that probably won't stop them from releasing an entry level 6-core.
If they boost the core counts of the normal/fast chiplets in the future, then core counts will rise across the board. For example, a 12-core chiplet would probably get disabled to 8-10 cores for the entry level, instead of 6. A 16-core chiplet could get disabled to 10-12. That is not happening with Zen 5 as far as we know.

Why Intel and AMD not make enthusiastic 100-200 core 6-7 GHz processors with TDP 1 kW for those who don't care how much they consume because already have 10-20 kW solar panel systems on their roof ? Let others be jealous. Green energy proponents will be dancing in joy.bananaforscale - Wednesday, October 18, 2023 - link

No, there IS a place for ALL the performance at ANY cost. Some people are like that really. Not everyone lives and dies based on power consumption like the comments have you believing. I don't care, I can pay the bill and it's really peanuts difference between a 14900k and a 7950x in terms of the difference it would make on the power bill. If I am looking for max performance for my usage that isn't even a consideration, only performance matters. By that measure the 14900k is better sometimes and sometimes not. So it would come down to very specific use cases. What I'm saying is, everyone here moans about power usage but ignores the fact that not everyone pinches pennies on the power bill or needs to worry about it and just wants the max performance. That's why 4090s exist and sell well.ItsAdam - Wednesday, October 18, 2023 - link
I own a 4090, still wouldn't buy a 14900k, was gonna buy then they decided to refresh.I dislike the heat element. This much possible power draw is broken,how can you cool that and maintain peak speeds. It's pointless.
The only ones who could use these are people on propper custom loops or ln2 overclocking.
They are literally pointless CPUs and the new gen of intel CPUs was just a total waste of time, development and retail. Just think how much waste they've made for this new gen that's the same, just the packaging and everything what a waste.
Pointless. Like your post.

I also dont buy this gen Intel processors, so what?Cheap solar energy and efficient heat pumps will slowly change mentality. Now power supply in PC 1kW, soon they will be 2 kW and rarely who will care. People don't care about power efficiency. 99.9% don't even know the price per kilowatt-hour. Kids playing games dont even want to hear about it. If you care then find the solutions how to use that possible 0.25-1 megawatt of solar power falling on your property. Power efficiency is just the salespeople buzzwordThe Von Matrices - Wednesday, October 18, 2023 - link
They already do make super-high TDP processors. They're called EYPC and Xeon.SanX - Thursday, October 19, 2023 - link
Server and supercomputer high core count chips heavily rely on power efficiency, hence they have clocks 2-3 GHz. For example the 64 core EPIC processor essentially equivalent to the future 24-32 core consumer processor at 6 GHZ at 3-5x cost. If someone worry too much about power consumption just buy couple used solar panels for 100 bucks and you will cut the cost by half or 100% with smart backupPeachNCream - Wednesday, October 18, 2023 - link
Those peak power numbers are disgustingly bad. I wouldn't want to pay the utility bill for that so I'm glad I paired a keyboard to my phone and make do with less than 8w peak total system power consumption. Oddly enough, I don't feel as though I'm missing anything without some obnoxious box filled with a CPU like one of these and some obesity-level graphics card.
