Worth upgrading from I7 10700K to i7 13700k/14700k? I have a 4090.

[Desolate Eden]

Will I see a noticeable upgrade in gaming performance to justify the upgrade?
I've seen some videos showing about 15-20 fps increase, but I'm on the fence.

On Intel i would only recommend the 14600K or 14700K for gaming. The 14600K is perfectly fine for the average gamer without breaking the bank. And as disappointing as the 14th gen is, if you are not on the new platform you can just go 14th gen.
The 14900K is simply not a gaming CPU, no matter how you try to spin it. And it costs significantly more while staying even in performance compared to the 7800X3D while drawing double the power. You are better off spending that money on games than the 14900K.

switching to last intel makes little sense. Stay or build with 7800x3d.

this is so wrong intel 14900k//13900k trades blows with the 7800x3d and beats it in the
1% lows in almost every game and when intel is overclock beat it in most.
intel hands down is more stable FACTS !!!

talk about a fanboy... I love intel but you cant deny the fact 7800x3d uses a fraction of the power, costs 60% the price (let alone talking about needed extremely high frequency ram, psu, cooler, mobo) and still beats the 14900k stock and competes well with a highly overclocked 14900k with overclocked 8000mhz ram

Im going to get a 7800xd for my next build which will cost me maybe £650 for mobo cpu and ram when the 14900k costs £550 on its own let alone needing probably a custom water cool loop or expensive 360mm aio just to maintain its temperatures at a good overclock

Intel benefits a lot from memory tuning. To achieve RAM speeds beyond the official 5600M/T, you need to overclock the memory controller. So 14900 is potentially the fastest gaming CPU when overclocked.

However, I also believe that Intel isn't worth it for most people in this generation. You'll have to shell out a big amount for the 14900, top-end cooling, top end RAM (7200-8000MT/s) and some selected top end motherboards that support such fast memory. All this if you are lucky with silicone lottery. Additionally, you might even need to pay somebody to tune everything for you. Also, there's the issue of higher energy bills, especially in Europe. Oh, and 200W of extra heat in your room that can be a problem in summer time.

all cpus perform better with faster ram
high speed with low timings help even more

the cpus imc can work much faster than they claim at stock
its just guaranteed to work at those speeds with 4 generic dimms

More like quadriple. :(

The sweet spot for the 7800x3D is 6000M/T CL30 due to the infinity fabric, and the CPU is generally not very sensitive to RAM speed because of the large amount of 3D cache memory.

On the other hand, for the 14900, fast memory is necessary to compete.

I'm aware of that. I talked specifically about gaming and not productive workload.

Even at gaming it's up to 4x more power.

[Illusion of Progress]

Back to the main question, I think sticking with your 10700K for now is the most sensible option. The 12th generation was a larger than usual uplift as far as Intel's new generations usually go, so it might make you feel like you have to have it, but the 10700K is more than fine for almost all scenarios right now. Going from one platform to the next, especially on Intel's side, is typically hardly worth it. I would wait for the next generations of CPUs from Intel and AMD before making a decision.

But sometimes the most sensible option isn't the best. The best is what we want as long as we can manage it. Maybe 15 to 20 FPS is a lot for you in some situations, or maybe you have extra money to spend on upgrades and don't see a better place elsewhere in the PC to put it. If any of that is true, there's nothing with upgrading a relatively modern and performant platform with one even newer and faster. It's just hardly necessary unless you feel like your current one is lacking in performance.

I disagree there.

given OP plays 1440p with an 4090 his gain by switching to an 14700k are more like 25-30 fps than 15-20.
(it be 15-20 if he played 4k)

a 4090 is 2100 euro.
if calculated flat :
not loosing out on 27% more of its performance is hence worth arpund 600 euro.
but as you pay a premium for those extra fps..

look at it this way : he now gets 4070 performance out a 4090.

a 4070 is 600.. so in facthe looses out on 1500 euro of value.

spending 450 euro on an 14700k is thus well worth it.

that 10700k still sells new for 280 euro so perhaps he can recoup some of that by sellings his 10700k.

granted the 14700k uses 250w the 10700k uses 125w

if one uses the pc for 40 hour a week that adds up to 260kwh in extra power per year.
at todays 40 eurocent per kwh thats 104 euro yearly.

stil if I set the costs :
1600 extra performance
-450 euro for the 14700k
+100 euro for selling the 10700k
=
1250 euro
/104 =
12 YEARS

nobody uses a pc that long.
the upgrade makes total sence!

============

-while I agree that if one builds from scratch one would pick the 78003DX but OP already has a system.

spending money on a new motherboard as well will not increase his performance.. as the 7800X3D does perform a little less than an 14700k.

first the negative an 7800X3D performs a a little less it drops the bottleneck to 7% not 5%.
thats not much but it still drops performance closer to an 4080.

4080 amd 4090 are about 8% apart.
1200 vs 2100 euro. those 8% are worth 100 euro each.

so your gain with an 7800X3D is only 1400 euro worth of performance.

that said :
it has a powerdraw of 120W about the same as he has now.. so thats 108 euro a year less in power.

-it is only 370 euro so 80 less to spend.

-but you also have to buy a motherboard 400 euro to have a good one (X670 chip, 4 ramsockets with suppport for high frequence, wifi 6 build in and good audiochip)

useralso currently uses ddr4.. going to am5 means new ram too.
a nice 32gb 2x16 7200mhz set with decent cas is around 200 euro.

so now OP looks to spending upfront
970 euro instead of 450.
while getting 2% less performance out it.
he is saving 108 in power at best..

but it takes 5 years to earn that back.

perhaps if he sells his current mobo + ram + cpu he can get 250 euro back instead of 100.

still npt enough to offset it.

the best option for OP remains : get that 14700k

[River]

I agree with both of you all.

It just all depends on if it is in your budget too I guess.

Still 15 fps to 20 fps in 4k or even 1440p can make a huge difference in some games. Not all but some.

[r.linder]

It’s less than 15 fps on average for 4K between 10th and 14th gen i7 K, that isn’t worth spending up to 1000 dollars when it still gets over 144 FPS.

[River]

Desolate Eden which games are we talking ?

[Agent]

Screw Intel, join AM5 and get the gamer's CPU 7800x3D.

And I was using the figures the OP gave that they supposedly researched. I don't know what they are.

The RTX 4090 is not going to perform like an RTX 4070 just because it's paired with a 10th generation instead of a 12th or newer generation.
