Hey guys , i have currently a bad 12900K that could do only 5.2ghz Pcores /4.2ghz Ecores under 1.52V llc4 but not anymore... I lost the silicon lottery but it already got worse for 5.1/4.1ghz i could do it with 1.37V when it was new and now i need like 1.45v for that. Stock will still work just fine as it blasts a ton of voltage for only 4.8ghz.

My mobo is the Z690 Hero and my DDR5 sticks are also bad as i paid a lot on launch for the Gskill Z5 6000mhz cas40 , which i could manage to do 6200mhz with 36cas at the very best and thats with monarchs as stock cooling was unexistent and would easily crash when getting hotter.

Its kinda embarrassing that i have a water chiller to cool effectively both this cpu and my 4090 just to get very mediocre results and burn a ton of power and create so much noise.

So is it worth it to change my 12900K and get a 14900K ? Or its just better to change mobo/cpu/ram on the next gen?

If you want to overclock and have some fun with it, the Apex Encore board + 14900K + a 48GB DDR5 kit would be nice. If it is worth it....well that is up to you. Intel Arrow Lake is probably a year from now. AMD Zen 5 I don't know.

Eh I 'upgraded' just because I lost 100 mhz on my ram.

5.1 all core thats 13600K stock speeds.

For me its worth it because its my hobby and personally I want to keep my maxed out DDR4, so I likely will skip a generation or two when it starts being DDR5 only which is what I've previously done.

Then again I've bought a new CPU each gen since 8th only skipping 11th so I dunno.

Probably will make your next gen jump better but you can try to sell ur 12900K and see how much you get and see if getting 14900K is worth it.

What do you mainly do with your computer?

Gaming-Benchmarking and working (really light load) sometimes but mostly gaming. The 12900K is a bottleneck for the 4090 for sure but i also know that the 14900k will be too.

That is the ultimate combo and i did regret for getting the hero and not the Apex even back in the z690 series and i will surely go for the next Apex as well because it is what i actually need but i wont spent so much cash for a mainly 13th gen refresh , it was more about economically upgrading the cpu only until the gen changes.

Its my hobby too and i understand what you are saying , its just that 14 gen is 13 gen actaully reminds me the 11th gen that was so bad too but i think this cpu starts to degrade too much and its time to change it. I never had chip degradation in the past and i always hit my cpus harder than "max safe" voltage limit value but it could be that now i have the chiller and i can blast even more than ever before.

Probably will make your next gen jump better but you can try to sell ur 12900K and see how much you get and see if getting 14900K is worth it.
Exactly what i am thinking about , i can sell this cpu for 250-300 , more like 250 as it works fine as stock and from there i can give another 250-300 for the 14900K , its not that much more.

Since you didn't go to 13900k/ks for the same reasons, I would say no...again for the same reasons.
Valid point !

But i didnt have that much degradation back then even if it start degrading quite fast it was doing it in a slower pace than now.

I went from a 12900KS to a 14900K in a z690 board. 28000 vs 40000 in R23
Nice ! How much did you manage to oc it?

I understand. I bought the Z790 Strix-E because the Apex was a bit too expensive compared to my previous Z490 Apex. I may have made a different choice now though.

If you don't need the extra performance now, hold off until the next gen.
 
#17 ·
At that point noone actually "needs" more performance , we always want more performance! :LOL:

Maybe i just sell the 12900k , get only the 14900k for 300 extra and then change the whole thing on the next gen. i am afraid that this cpu wont last for long as it goes.

Yea… depends on the game and how much cpu get utilized as too how bottlenecked gpu is. A game that sticks out in this situation is flight sim 2020 and another older game i run like farm simulator 17. Low cpu utilization and 4090 is idling along. Wonder how much that intel apo would games like that? Have to wait and see. If money burning a hole in your pocket just put in a 14900k now then be done with it haha! If not then maybe wait what next gen has to offer… how much will power do you have?😄
You got a point , maybe i just have to get both the 14900k and upgrade on the next gen , if i sell the cpu i currently have i will only pay 300 extra for the 14900k which is not that much.

Comparing to 11th gen isn't really fair at all. 14th gen is still an improvement over 13th gen. Its not much improvement but yes its better.

11700K was slower in a lot of situations than the 10700K because of the gimped IMC. 11900K was slower than the 10900K in even more situations for the same reason plus fewer cores.

Negativity towards 14th gen is highly exaggerated, if you already have a 13th gen and consider it too small an improvement then no one is making you buy it. They are however still better chips no matter how slight.

Also historically, Intel always get blasted for only offering 2 CPU cycles per mottherboard series. This time they offer 3 cycles and still get blasted.
Lol , yeah 11th gen was indeed a humiliation , from what i seen at least the 14900k seems to run cooler than the 13900ks and clocked a bit higher , that should allow me to at least push it even more. Do you know what is the average oc of these chips ?

They should be blasted. I've yet to see any reason to even consider 14th "gen" a new gen. When Haswell had a refresh it was just part of the same gen (i.e. 4770k refreshed with a 4790k).

Calling it a new gen is just dumb. Call it what you want, its a refresh of Raptor Lake, so it's still 2 gens of support for the socket with a refresh of the 2nd one.

But its not a new gen, its a refresh.

There was also very little architectural difference between 8th-10th gen, just more cores and higher speeds.

Yes the average Oc is stock speed.

But consider that 5.7 all core runs cooler on 14900K than 5.7 one core does on a 13600K.

Even people here that are OCing to 5.8 all P core / 4.6 e cores and such need to turn off hyperthreading to do so. To just maintain the 5.7 all core boost in cinebench you are in the region of 325-350w, maybe even more on worse chips.

My max I managed in cinebench was 5.6 all core maintained at 525w with temps going to 96-97, but my 13600KF was kind of the same plus 10c hotter in gaming at its max OC plus less voltage :x. But more like I didn't correctly tune the voltage curve on it and just left it at manual volts, doing that = degradation.

Good lord ! I could barely cool my 12900K that is lapped + Liquid Metal under 300watts in Ycruncher.

At 350 watts the waterblock won’t make it , how do you stress test these cpus for stability without throttling ?

I know , I am manually overclocking as well , I like my chip to retain the max clock speed no matter what.

I don't think you can, even at 325w PL I throttle to 5.6 in cinebench with super tuned AC_LL and undervolt.

A bit contradictory 😋
Well the 13600KF (pre degradation) was at 5.7 / 5.6 / 5.6 / 5.5 / 5.5 / 5.5 and the same cinebench temps and higher gaming temps. Fixed voltage 1.33v on 13600KF vs max voltage 1.36v on 14900K.

This 14900K is 10c cooler in gaming while maintaining 5.7 all core. The main difference is 1.33v fixed vs 1.25-1.36 curve. Also 1.225v minimums were fine in games but not cinebench, so I might set it back to AC_LL 50, -0.05 which gave a 1.225-1.38v curve and use -1 AVX offset instead.

I recently upgraded my full Strix z690-i workstation / 4K gaming pc from 12700K + 64GB 6400 + 3070oc 8GB to -> 14900K + 96GB 7200 + 3090oc 24GB. I run a Lian Li / Dan Case H2O mini-itx with a 240mm AIO for cooling + Corsair SF750 psu. I run AIOC full unlocked with HyperThreading off and 90C cutoff per core to keep everything cool and clocks as high as possible. The 12700K ran 5.6 all core boost and could stay in boost all the time, 5.4 all core load, 4.6 ring, 400Mhz idle, offset to 5.3 for avx etc and temps stay 70C's under load and 25C idle @ 11w. Stock Cinebench is 25k @ 253w, max 26k @ 266w, tuned 20k @ 180w. Memory was a pain to sort out and stabilize, takes a bit of voltage to make everything happy. The 14900K's new per core throttling forces me to run Auto voltage instead of a manual undervolt. However, manually adjusting the cooler score lower in AIOC settings effectively does the same thing as it still allows the 14900K to boost to 6.2 on 3 cores, 5.9 on rest, 5.7 full load, 5.0 ring, 800Mhz idle. Temps are same targets as before, 70'C's under continuous load, and 25C idle @ 12w. Stock Cinebench is 40k @ 348w, tuned is 35k @ 280w. Memory @ 6800 XMP booted straight away without issue, and was able to get it pretty dialed in @ 7200 with tighter timings fairly quickly. I also run the 3090oc undervolted to just under 300w, as this shaves off almost all excess heat dumped into the 240AIO and still keeps all performance as the memory stays cooler. Overall the system is incredibly balanced and efficient, and I am very pleased with my upgrades. It has already made a notable difference in my ability to multi-task during workflow, and 4K game time on the 55" LG C1 oled is pretty sweet too.

14900k will have a better IMC than 12th gen but same as 13th gen, a 13900k would make more sense cuz cheaper
Not really here the 13900k costs the same and the 13900ks that is closer to the 14900k costs 100 more ! The imc may be better but i dont think my sticks can do any better than that but even changing the sticks i dont know how much will be worth it as i dont know even know if the z690 hero board can do 7000mhz+ which i highly doubt.

You did some fine tuning there , glad to hear that you managed to do 7000mhz+ on your z690 board. So what do you think is it worth it?

if you could get the ks for cheaper then get the ks rather than the 14900k, the ks is binned so you would have better luck with getting a good imc rather than getting a 14900k which to my knowledge is not binned as hard as the ks

Z790 Apex is 650 USD.
14700K is 600 USD
DDR5 8000 is between 210-270 USD
~1500 USD for a new rig.

Is that worth it from a 12900K? No.
I would stick it out for an extra year till meteor lake.
his z690 is fine $0, 14900K $600, 32GB 7200 A-die $140 / 48GB 7200 $200

$800 to upgrade from 12900K + 6000CL36

If you're buying an apex to begin with you really should be going all out with ram water cooling and a custom loop to actually get usable benefits of a board like that, and money really should not be a factor at that point.

I listed my cpu for 280 locally, probably will give it for 250 euros , if I am able to sell it then I will just get the 14900KF for less than 300 more and call it a day.

I will not change ram sticks and mobo as it’s clearly not worth the huge price difference on that same generation.

will change everything on next gen if the performance gain is big.

I will aim for maximum cpu clock speeds , my chiller will help to maximise the CPUs full potential as it did for my 12900K.
