So the last pc I built, Devils Canyon z97 chipset, needless to say its been a while. It worked great for everything I needed for a long time. I moved into my house that I couldn't get internet for, 6 years ago and just let it sit. They finally laid fiber in front of my house so I've decided now is the time for a new computer. I intended to run a gpu, so I'm like why bother getting a cpu with iGPU when its not needed and the price would be lower without it. But I wondered if not having iGPU would cause any issues, but my googlefu is not what it used to be and I'm not really finding the answers I'm looking for. The pc would be used for CAD, some gaming, and drawing/photo editing. If a person is using a GPU would they run into any issues using KF instead of K.
Advantages of KF over K, iGPU or No iGPU?

Useful for troubleshooting sometimes.
Some programs can use Intel QuickSync for video encoding, which uses the iGPU.

While it was some time ago, I used to run 3x1+1 (7680x1440+1920x1200) on a single TitanX and there was no discernable decrease in FPS or increase in temperatures with the accessory monitor. I wouldn't worry too much.

In my opionion it depends: there could be some cases in wich an igpu could be usefull, maybe even just for test the system without the gpu, vbios problems etc. Anyway it depends on the cost. if you're gonna pay it 20€$ more i suggest you to take the igpu, for more, like 100€$ buy a KF unless you really need the igpu.

KF processors cannot be tuned via XTU.
KF processors will not generate as much heat in some situations, given the fact they don't have a GPU.
Other than that, they are identical processors and the bins (KF v K) are just about the same.

I have been tuning mine in xtu, what are you talking about?

i suspect kf's will be on average lower binned. for a k to make it market, it has to have both a sufficient performance of the p-cores and e-cores as well as a functioning igpu. k's with non functioning igpu become kf's. so the selection criteria for k's is higher.

NVM looks like the product specs list KF as well, for some reason it wasn't working with my 9th gen KF.

Nope, binning is pretty much identical. In fact, it looks like the KF might have a slight edge

how can i see sp score of my chip? i am curious what it is. the gigabyte bios gives inconsistent result(gigabyte calls the feature "CPU biscuits". sometimes it says out of range, some times it says 99, 93,94, or 95. I don't know how that relates to SP.

There's zero difference in temps from what I saw. The iGPU is limited to 15W overclocked and juiced up. I'd say iGPU can be useful when diagnosing potentially dead or damaged GFX.
Here's some binning data from igorslab if you care to read: 500 chips, 13900k vs 13900KF, overall SP, P-core SP, E-core SP and IMC SP.

Just in time for Christmas we have something special for you today. With the help of MIFCOM, we were allowed to bin a statistically not insignificant amount of CPUs (over 500 in total) and today we…

Hey all,
Binning on specific editions isn't aimed for it's completely random, in a few months you could find that the KF series will pass the K editions purely because intel need more KFs over Ks due to market demand, so they start using the entire cylinder of silicon for KF edition processors thereby using the middle of said cylinder and thus giving you a lot of binned cores.
As for any performance differences between the K and KF, none, not a single one. The fabrication is the same, the design with the exception of an iGPU is the same, the memory controller is the same. I think the only real, solid difference may be the amount of vcore you can push through the CPU and that would be down to heat if you're using the iGPU, I think that would pretty much come to a handful of degrees, nothing a decent cooler wouldn't deal with.
The other benefits of having an iGPU as mentioned before would be diagnostics, for the sake of £20 I'd get the K, it'll overclock the same.
Cheers

I just picked up a 12100 on sale after 13th gen non Ks dropped.
12100F £95
13100F £119
13100 £149
I found a 12100 sold by Amazon, last one left for £116.
I wanted the iGPU as is going in a test bench,, though I do already have a 2 Gb radeon 550 for it, if somehow that GPU fails I can't get another cheap GPU now, also I've used the current G4560 iGPU a lot while GPU bios flashing and recovering failed flashes so yea, go go 12100 super deal!
Also frigging pentium G7400 still £93 lolwut?
Intel really overvalue their iGPU, but if you ever want to bios flash GPUs you'd better have an iGPU.

With the KS promotional video recently released, this now makes more sense than my previous theory of failed igpu chips.
Intel said they need to purposefully gimp any silicon to meet market demand on lower SKUs, so if theres more demand for KF, they cut more chips regardless of how good they are.
At least they don't do what Nvidia did .... Heres a £650 3080 but no one can buy one.

thanks guys.
seeing alot of the testing I saw people doing on the i9-13900k/kf is the reason I started wondering cause alot of the testing I was seeing indicated the KF was slightly better. made me think maybe the lack of igpu freed up something on the cpu, L3 cache or what not. other thing I was thinking was the lack of igpu may help with the heat. As I have been reading these chips get hotter than what I may been used to. I guess between the 2 the differences are negligible.

There is no difference between the K or KF besides the iGPU being/not being built-in.
The iGPU since Alder Lake is powered by a separate source, so it no longer affects the overclockability of the cores or cache.
The primary reason why the KF seems to be overall better is because they don't get binned for the eventual KS, unlike the K.
