How many cores do you really need?
For gaming. I am looking to get a cpu. Currently I use the I9 9900KF in my system. I am looking to build a new pc and already got a gpu(RTX 5070TI). I was looking at the I9 14900KF but a few things.

It runs hot. Now I will have a good water cooler set up. But still I don't need something that runs hot on idle. Looking at the cpu it has about 24 core. 8 P Cores and 16 E Cores.

I looked online and some say you only really need 8 cores to run most games and new games coming out.

First post!

All of them and more if you can. Ai is coming.

Oh. And I hope nvidia releases their cpu

Disable the e cores if all you do is game or go visit team red.

Though 360 aio's can be had pretty cheap and the 14700kf doesn't run that hot.

I have an air cooler on my 14900k that can handle 270watts.

Be Quiet, Dark Rock Pro 5.

Works so good I turned Ecores and hyperthreading back on.

depends on what you are doing
games do not need alot of cores, just better core performance
amd x3d cpus are top for high fps

while tasks that are highly threaded like having more cores even if they do not perform as well
thats where intel e cores help, along with background tasks

Yea you want 8 real cores and high frequency with low latency ram and that cpu is not a gaming cpu. Proof? No X3D cache and it has E cores and an igpu too right? Its a hybrid cpu that intel know gamers buy as they had no other choice. I am still waiting for the X3D stacked cpu with noigpu no HT/SMT and simply 8 really highly clocked cores say 7GHZ+DDR6.

disabling e cores is totally unnecessary i tried it on my 14900k made no difference to speak
of and with everyone monitoring/streaming and everything else while gaming.why would you want to dump the load on to the p cores while gaming makes zero sense.

If you are pushing a big overclock it helps and I tend to think anyone buying Intel still has to be overclocking else it's just worse than AMD and not really a competition, plus, if you are streaming, you aren't just gaming, as I said.

Then I have to guess it is running stock or a very mild tune, else you got lucky, or you are throttling at times.

So 24 cores is just eye candy so to speak.

No, the Bios has the correct setting limiting the 14900k to 253 watts.

So I was right.

Moving right along.
9800X3D or wait for 9950X3D2 in 1Q 2026.

93 cores and 600 threads + an rtx ryzen 9080 TI super 80+ ruby

low end system, 8 cores are nothing nowadays

I would go Alderlake (12th gen) than Rocket Lake-Refresh (14th gen)

Get a Z690 board, I use a MSI Pro Z690-A DDR4 board with Trident-Z Royals 32GB 3600 C16 kit that I easily OC'd to 3733 C14-14-14-28, bought it in 2021 with a $229 i5-12600K Micro-Center deal, last year I updated the CPU to i9-12900KS that only cost me $250 from Amazon.
I upgraded the GPU initially from Aorus GTX 1660 Ti to XFX Radeon RX 6800 MERC to Sapphire RX 7900 XTX Nitro+ when I got the 12900KS. CPU runs rock solid, performs right up there with the 13700K and 14700K in single thread but with none of the degrading instability.

I think going 12900KS from a 9900KF would be a big jump in performance, especially for a RTX 5070 Ti.

Get the DDR5 variant of my Pro Z690-A board, as I know I could have even greater performance had I gone DDR5 back in 2021, but instead my actions were because I wanted to retain my components I had then from the system I upgraded from which I believe was a Ryzen 5 2600.

Now if you want to leave the Intel family and go AMD, then I recommend AM5, 7800X3D or 9800X3D, 9900X3D, 9950X3D.
