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

Single-threaded performance is only one element in regard to performance on a multi-core processor, and it's time to look at multi-threaded performance in SPEC2017. Although things in the single-threaded SPEC2017 testing showed that both Zen 4 and Raptor Lake were consistently at loggerheads, let's look at data in the Rate-N multi-threaded section.
Looking at multi-threaded performance in SPECint2017, the only test that seemed to benefit from the increased core clock speeds of the Core i9-14900K was in 502.gcc_r, which is a simulation based on the GNU C compiler that analyzes source code inputs and compiles a few large files instead of many different small files. In this instance, we saw 34% more performance with the Core i9-14900K than the Core i9-13900K, but we are currently re-testing to ensure this isn't an anomaly and is an accurate representation.
Of course, it's also fair to assume that the clock speed increase yields a benefit, although we aren't seeing this translate to more performance in other tests within the SPECint2017 MT suite.
The last section of our SPEC2017 testing is the SPECfp2017 MT, and once again, we are seeing some gains, but they are very marginal at most. We did actually see some regression in one test, 511.povray_r, which represents a 2560 x 2048 pixel rendering of a chess board and is saved as a Targa (.tga) file extension. Given that we also run a specific Persistence of Ray tracing (POVRay) test in our suite, and we didn't see this regression here, it could be an anomaly, and as we've stated, we are re-testing SPEC to eliminate any of these anomalies or variations.
Overall, in both ST and MT SPEC2017 suite performance, the Intel Core i9-14900K doesn't represent significant gains in performance over the Core i9-13900K.

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
