13th gen is faster, but 13th and 14th gen is under fire currently for high failure rates. As others have stated, a 12900k is closer to a 13700k in core count or even a 13600k in actual performance in say, gaming. The only advantages of the 12900k are stability (since it isnt affected by the issues the newer chips are) and sometimes price. Like if you got a microcenter in your area and you can get that sweet sweet $400 12900k bundle, and you arent interested in AMD, 12900k all day. otherwise it's kinda overprice for what you get and you can do better with 13th gen assuming you dont get a lemon.

February 12, 2023 - ... Agree 13700k/kf is probably the best bet .. but comparing it to a 13900k: Around 95% perf in 1-2 core/games Around 75% in multicore, due to 13900k having 8 extra e-cores (also makes it hotter & hungrier)

12900ks vs 13900k? : r/intel
January 1, 2023 - I have no doubt that the 13700K will perform above a 12900K, and probably even above the 12900KS. ... 13900K at 65W matches 12900K at 241W. That gives 13900K a massive thermal headroom to improve performance when it is given more power. 12900KS doesn’t have similar headroom.

r/PcBuild on Reddit: i9 12900k or i9 13900k for Gaming/Streaming Build?
July 20, 2023 -

Due to an insane sale I purchased the i9 12900k for $356.99, from its original price of $619.99. This CPU already hits all the marks for what I want it to do. I want to be able to game with high resolutions and a high refresh rate, as well as potentially stream. I do some graphic work but not anything crazy as my i7 8700 has been able to run all my graphics projects just fine. Due to an opportunity I have from work I would be able to purchase the i9 13900k for $409.99 which is not much more than what I paid for the 1200k. Even though I know it benchmarks higher, especially for multithread benchmarking I am very tempted to get it, but I am asking myself if it is worth the jump for what I’m doing. Both CPUs seem to be very positively perceived by the public, and users seem very happy with them. I’m not doing any 3D rendering, and I’m not sure how much 4K gaming I’ll really be doing. My monitors are only 2k at 165hz which is still plenty good, no need to update these anytime soon. The only thing I saw that was somewhat concerning was just the 13900k tends to run hotter. I’m not sure how much this will really play a role since both the case and cooler I’m looking at cool the system well and have good ventilation. For the most part both CPUs seemed reliable as well. One of the factors in my decision making is also that due to where I purchased my 12900k, I get protection included with my CPU if anything were to happen to it. With the 13900k I wouldn’t get any coverage on it due where I’m purchasing it from, so I’m just trying to analyze the risks.

This is also my first pc build and I still have stuff to learn, so any alternative opinions would help in the matter.

I am going to be getting a new processor at the end of the month.

I was originally going to get the 13900K which retails for around $790 Canadian for me.

But, a Canadian online retailer has the 12900KS on sale for $669.99 Canadian. Thats a $320 dollar savings.

I am honestly torn between the two.

Which would you go for?

A 13900k is significantly faster than the 12900ks. It has about 10% better single P-core performance, 8 more E-cores, significantly more L2 cache, etc. Overall, barring GPU or memory bottlenecking (which, depending on your other parts, may happen in some games), you can achieve at least 10-15% more FPS in games by going with the 13th gen part. At those prices, the 12900ks is a slightly better value (though neither is exactly a bang for your buck choice) if gaming is your primary workload while extremely heavily threaded workloads would favor the 8 more threads of the 13900k, but overall if you can afford either there's not a "wrong" decision. I'd probably go 13th gen between the two if I could afford it, though especially if you don't completely need 32 threads (which you clearly don't if you're considering 12900KS), the "best" option for your money is clear: neither.

A 13700K has exactly the same core config as 12th gen i9s (8 P, 8 E), and while it technically doesn't get peak boost clocks as high as the 12900KS (5.4GHz vs 5.5GHz is a negligible difference), its single thread performance is slightly higher due to IPC improvements, it has double the L2 cache of the 12900KS due to Raptor Lake's superior cache per core, and overall provides 99% of the gaming performance of the 13900K while still slightly beating the 12900KS in productivity tasks. And as to price comparison? The 12900KS on Canadian PCPartpicker is CAD$665, while the 13700K is CAD$546. So again, unless you need absolutely insane multithreaded performance, the answer is just to get a 13700K.

An alternative if you don't already have an LGA1700 motherboard (which it sounds like you may, but worth considering if you don't) and you don't even need the thread count of the 13700K (you probably don't) might be the Ryzen 7700X- it's about CAD$450 and is within about 3-4% of the gaming performance of the 13700K while having lower peak power draw and still having a very solid 8 cores/16 threads. It still beats the 12900KS in gaming performance by about 8%, but if you already have a Z690 or Z790 then you won't save enough to make it worth buying over an Intel equivalent.

Frankly I think you might want to be comparing the 13700vs13900, as I'm assuming the 13700>12900ks.

While we don't have a clear look at the performance differences between Raptor Lake and Alder Lake yet, if given the choice between purchasing a new i9 13900k at Intel's announced pricing and an i9 12900k at a discounted price of say $400 flat, which would you choose? I'm just looking for others' thoughts to inform my purchasing decision once the new CPUs drop.

Hi. I have 12900K stock

32 GB 2x16 GB DDR4 3600mhz

Palit Gamerock Pro OC rtx 4090

1300W Seasonic Platinum Prime

Aorus Elite DDR4 Z690

Windows 11 2H22. Updated new nvidia drivers.

I test that place in CB2077 <market place> and i am gettin on my pc 70-80fps , thats on 1080P dlss quality

. When someone with 13900K and DDR4 and rtx 4090 have 120-130fps. Why i am here with low fps? Link hes performance:

Market:

https://www.youtube.com/watch?time_continue=1&v=4C-z008MbFg&feature=emb_title

I have 30-40fps less than on 13900k. He said he is using CROWD DENSITY HIGH but i saw that i have many more peoples on this market than him.

And my question is. Is any sense now to change for 13900K?

r/intel on Reddit: 12900K vs. 13900K features missing?
February 26, 2023 -

I'm planning a new workstation (self-employed IT-engineer, virtualization/lab/pentesting purposes and much more) and gaming build for a while now and was doing some research on the 12900K, which was on my list. I then noticed, that the 13900K has been released recently and so I was checking the differences of those two models.

While everyone online is saying that the 13900K is obviously better than the previous model, which makes sense in terms of performance, I was wondering why nobody was talking about these missing security features in the 13900K cpu:

Intel® vPro Enterprise
Intel® Total Memory Encryption - Multi Key
Intel® Total Memory Encryption
Intel® Threat Detection Technology (TDT)
Intel® One-Click Recovery
Intel® Hardware Shield Eligibility

I have to admit, I'm not that deep into hardware technologies (yet) and when I tried researching on most of those it got a bit too abstract for me, that's why these questions immediately pop up in my head:

Are these technologies, which I should prioritize higher in my use-case than the performance?

If anyone knows: Why did Intel ditch those features? Is there a cpu model which has the performance of the 13900K with the features of 12900K?

So first time building and I've done plenty of research, but I'm debating between processors because of these recent power issues with 13th and 14th gen. My goal is productivity because I do research a lot and so I need to open a lot of tabs and I also do video recording and video rendering. I'm also interested in playing some games but it's not my main focus. So ultimately I want a balance. Originally I was going to go with the 13900k and a 4070 TI super 16 GB, but after seeing that all of these power issues are basically making people have to set the power limit to like 188 or whatever it is (some have said 253 but I'm not sure why gigabyte has set it to 188) it just seems like a real hassle and on top of that you are signing up for lower performance than what you paid for.

So I decided to downgrade to a 12900k and a 4070. Got both for like under $900 after taxes so it wasn't bad.

I guess my question is would it be worth the hassle of getting the 13900k? Are they going to change these things to make them actually worth what you're buying or are people just buying them and settling for lower performance which seems to me kind of silly. Is there a significant difference between these two considering that the latter will be nerfed because of these power limits?

Curious on various thoughts thanks

Hey guys,

I currently have a 5 year old PC and want to build a new one within the next few days. First I looked at the 12900k as the "obvious" choice - then I read about the 13th gen and now I wonder what to do. Originally I had the 5800X3D in mind as I only play games with my PC, then wanted something from Intel as I had issues with my previous 2 Ryzen cpus already. Now I am stuck with these 3 and have no idea at all if spending more is "worth" it or not. I do not mind paying extra, but also not looking to get 0.3% more performance for 300 bucks in exchange. Plan is to run it with a 3080 12GB for now.

Playing all sorts of games and I don't really want to upgrade within the next 12-18 months already. Any info is appreciated, been reading tons of reviews, benchmarks etc. and I am starting to feel super lost now.

Bit of a dumbo when it comes to more detailed hardware stuff, so please forgive me.

edit: i9-12900k of course, just shows you how confused I am already.

I bought the i9 12900K and I started regretting it because of all of the people talking about the 12900K bottlenecking the 4090, I bought the 12900K and I can’t return it, but I’ve thought of selling it, if it’s really gonna make a difference.

do u think I should upgrade from 12900K to 13900K, and if I should would I need to upgrade my psu to 1200w?

I’ll be using it for unreal engine, 3D game development, and gaming.

My pc:

Ram: DDR5 64 GB

GPU: rtx 4090

Psu: 1000w
