It comes in handy if you have no GPU, for whatever reason. Other than than not much point personally

 

Useful for troubleshooting sometimes.

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

 

It's only $20 extra. Thinking about adding a small monitor for my PC status on the iPGU, not load my GPU with that maybe.

 

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.

 

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

 

I used a KF in my new build, because I believe the only real use for the iGPU is to have backup video if your GPU dies / is sold. Outside of that, I don't think it will provide any real benefit for you.

 

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
Comps.

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.

 

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.

 

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.

 

iGPU can be handy sometimes, for example if you're having an issue with your graphics card or monitor and need to rule things out, also useful if your GPU dies, at least you have a computer still for other things while you wait for a new one to get there

It can also be used in some applications for video encoding

Also down the line when you upgrade it means you could turn a system with that cpu in it into a cheap server or like, second machine without having to buy a GPU

 

K for multiple monitors and QuickSync.

 

I have two PCs and one has a i5-4600kf and the other has a i5-4600k both are running RTX 4900, DDR5 @ 6200ghz CL32 @ 4k using 2x LG C3 42 inch monitor/tvs.

For the last 24 hours I have spent fine tuning these CPUs. In stock form they are great, and the Arctic Liquid Freezer II Gen 3, 360mm ARGB AIO Liquid CPU Coolers do fantastic jobs.

Firstly, Intel nerfed these CPUs for reasons I think is obvious. They beat my mates OC'd i7-13700k in all gaming benchmarks at all resolutions and this is why.

I wanted to see how far I could drop the voltage for the P and E cores and still get the same performance and stability in Cinebench 2024.. try taking 30% off.. The KF does outperform the K as even with the iGPU disabled, not having it on the die makes for extra space and some other reasons relating to that (assumably).

With the KF I have managed all P-Cores running at 5.9ghz and all E-Cores at 4.4ghz at 1.35 adaptive -0.05v with ring at 4.3ghz. Long story short. I am very impressed.. Where the best I can do with the K is still very good, but stable P-core 5.6ghz and e-core 4.1ghz and ring 4ghz @ 1.41v

Oh, my post above was pointless - you revived an old thread! (it's better to start a new one). I'm sure he's been filled in since 10 months ago!

Btw, you're missing the 1 in front of your CPU "14600KF"
This thread is Z97 platform, not Z890 (or whatever it is now)

 

6 years no internet?! I need to fill you in!

Your googlefu is fine, they've been deleting the internet!

• Every western country has doubled its debt which was just a bunch of transfer payments to accounts that aren't really accessed by anyone for anything
• Every western country has let in 4000% more refugees economic migrants than they can support, not screening them for skills they actually need, like has normally been done throughout history (not checking for transmissible diseases like TB or Chagas either, or previous criminality of various sorts including a lot of the worst kinds!)
• There are housing crises anywhere worth living
• Wages still haven't gone up (housing ~250%, wages 30%-same timeframe)
• We're on the verge of a health crisis. Sorry - can't tell you why! (my pc has 9 intel turbo Boosters though!)
• All the zombies think they're a-"woke". ("woke" means accepting things that don't make sense and sorting people into different groups according to their skin tone and giving some of those groups preferential treatment while hating others and pretending it's ok)
• Can't forget: there are lots of hoes now, and that's not an understatement: it's official! "More hoes than teachers, actually!" And that's not a figure of speech, no... there are literally more of them than teachers (and since those people don't live in a vacuum, I hope you're already married because if not? Good luck dating!!!!)

I hope you had a lot of fun time on your vacation from the internet, because there ain't much more to be had my friend

 

Going back to this, there was a higher chance of getting a high SP on a KF than a K, due to chips that were being binned for the KS with any iGPU issues being sold as a KF instead.

For 14th gen, all the signs seem to point to there not being any binning for KS's going on - the 14900K and KF this time are mostly the same, and with the 14900K being mostly identical to the 13900KS in terms of binning and power draw, it doesn't look like theres any headroom for a 14900KS.

The 14900K / KF are basically just a cheaper 13900KS, Imo worth getting if you were already considering the 13900KS but didn't buy one yet.

 

This is the first time I have bought a i5 rather than a i7 or i9. Being able to clock to 6ghz all core quite easily but instead keep it at 5.8ghz at max of 1.22v and e-cores at 4.4ghz, ring 4.8ghz it uses no more than 160w during 100% load in cinebench r23 or 2024 etc. Plus rest of computer components don't get any heat soak when the hottest a core gets is low 70s.

When my i7-12700k could do 5.1ghz all day all cores the extra voltage from 5.0 to 5.1ghz wasn't worth it.

So, now I'm a tree hugger using a balanced power plan, undervolted cpu and gpu with higher clocks.

But right now (think I'm still a bit drunk) heading to the store to buy g.skill 6400mhz cl32 64gb (2x32gb) (F5-6400J3239G32GX2-TZ5RW) as 32gb of 5600 @ 5800 cl36 ddr5 isn't enough for my personal memory leaking money making programs. Ahem..

As I have the nzxt elite case with a upgraded read 140mm white quiet fan, the ram has to be white though. . And no RGB. Only colours I want to see are my keys and monitor. . And my case is somewhat hidden. It may not make sense, but if I ever take it outside, at least the sun rays will reflect away.. yessss

 

Ah yes, mike7877 thank you for the update. In this past year I have for sure been scrounging the deepest of darkest holes on the internet to catch up.

I did end up getting a i9-13900k with 32gb of ddr5-5600 and I ended up reusing my old 970's, I was gonna buy a 4090 but with the burning plugs I held off. Its been fine with CAD and the little bit of light gaming I've been doing. Though I don't think it will be much longer before I stop putting it off, starting to get that itch again.
