K vs KF versions of Intel CPUs and heat and overclocking/binning/undervolting potential

[Wolverine2349]

Do the KF version have any differences other than no iGPU??

And because it has no iGPU could it run a little cooler and overclock better

Is the iGPU actually fused off, or just disabled??

I hear some people upon research saying there should be no difference and just disable the iGPU and when using dedicated card the iGPU is not used at all and is disabled and there should be no heat as such.

However in HWInfo64, it has an entry for GPU GT cores. I mean why would it if they are disabled and it does not show any Intel integrated graphics in Device Manager.

I also have iGPU for multi monitor disabled in the Asus BIOS and Primary graphics if set to Auto or PEG it is the same.

So would the KF not have that entry for iGPU in HWInfo64 and be better??

I mean the e-cores are not shown at all despite them being there and able to be used cause the motherboard turned them off successfully. So why is it showing the CPU GT cores of integrated graphics is disabled.

Cannot find where to upload the screenshot I took of it in HWInfo64 and Device Manager of it showing only my dedicated discrete RTX 3090 Ti.

And how would difference be between a 13900K and 13900KF for overclocking it on a large dual tower air cooler with e-cores of course disabled.

no difference other than igpu. normally the k costs more, but sell for more used than the KF

I think this would be a good question for someone like buildzoid. He has a couple of videos where he talks about different SKUs/quality/overclocks, like this one (data).

If I'm reading it right, it looks like their KF models were consistently (9th and 10th gen) a bit better than the K:

And because it has no iGPU could it run a little cooler and overclock better

Or perhaps the iGPU failed because the silicon quality is poor?
In reality, same silicon lottery for both.

You mean K costs for more up front by like $25 to $30 and t also sells for more used. Or that the KF sells for more used??

iGPU are laser cut on the KF skus
Using a dgpu on a K or KF sku is exactly the same
There‘s no difference in cooling or OC potential whatsoever with a K or KF. You’re still subject to core and imc lottery
There’s no way to enable iGPU on a KF sku (before that comes up). See point 1

The k models cost more and sell for more.

The kf costs less and sells for less
