It is fun to overclock an Intel CPU and I have 3 Intel CPUs with a K SKU. But the latest CPU I bought, is a non-K, I7-10700. It is $50/$60 cheaper, it is for my wife, who is not interested in overclocking, but I still have paired it with Z490 motherboard so she can have a higher speed RAM. I bought the motherboard, new, from a guy who bought a combo deal from Newegg and he cared only for the GPU. I paid for an Asus Z490-A Prime $150. The two things I do not like about the K SKU CPUs are (1) that some of them are really bad overclockers and (2) you need a good PSU and a CPU cooler if you really want to push it hard.

A couple of hundred MHz is negligable in gaming. When the non-k part is maxed out on all cores, it would be time to upgrade the equivalent k-part anyway. I sometimes wonder why people bother overclocking anyway. Then you get nerds like Debauer who are OC-ing champs, which is nothing but a waste of carbon footprint.
Yes I have done minor overclocks when a game can't quite be maxed to 60fps by the GPU. What's 100MHz on the GPU though? It's the difference between lows of 55fps, and CPU/GPU overclocked to get 56-7fps. Why bother putting that extra bit of heat on the chip and slightly risking killing it.

After seeing this video, I now feel justified in buying a non-K CPU and motherboard. I originally had an i7-8700 on a H370 motherboard and have just recently upgraded to an i9-9900 (on the same motherboard) and after seeing all the controversy surrounding the i9-9900K it seems in hindsight I unintentionally made the right choice (looking at stock benchmarks the i9-9900 and i9-9900K are identical. BTW in my HTPC I have an i5-8600K on a z370 motherboard which has never been overclocked. So, I agree 100% save your money if you are unlikely to ever overclock your CPU!

I have a 10th Gen I-7 10700 and it runs at 65W. All of the K's I can upgrade to are 125W. The I-7's have a 16MB cache, the I-9's have a 20MB cache, most are only. 4 GHz faster, although it doesn't say the FSB speed which I would imagine is the same since it's the same chipset so throughput speed wouldn't really change. I have a Dell 8940 with a 360W power supply and there doesn't seem to be a larger power supply I can install so even if I got the K CPU what kind of drain would I get since it uses 125W compared to the 65W for the non-K?

i9 10900 vs i9 10900k. lets see 65 watts vs 95watts (or 200+ if overclocked a lot. much more heat generated needing much more cooling. all for between 1% and 10% more fps in some games with 2080 ti.
Using many times the energy/watts and producing much more heat and using expensive cooler for less than 10% gain IN SOME GAMES. also K chip costs more hahaha its so strange why so many people recommend K chip I dont get it

Over clocking lowers the lifespan of your cpu big time. I overclocked a i7 4790k and it died after a year. Now I got a i7 10700f. He is 100% right I was one of those people that would feel bothered knowing someone was getting 100 or 200hz more. But after only a year my cpu died it woke me up and now I would rather put the extra money that over clocking cost into getting a better SSD or a better GPU

What about the 10i7FNHAA what FNHAA stands for? Also, it doesnt have K which means it non overclock CPU. If it is true then why the specs says BASE frequency 1. 1Ghz and MAX frequency 4. 7Ghz. If this CPU is non overclock then whats meaning of low freq 1. 1 and high freq 4. 7. Please let me know sir.

I got 9700k because I found used one for $252 which was cheaper than 9700 at $285. I gave up overclocking because non overclocking like-new condition used asus mobo is $80 cheaper at $48. So $300 for cpu and mobo combo is good deal in my opinion. And I hate electronics running hot.

the difference is k 125tdp vs non-k 65tdp. its what makes amd look better at 105tdp but they're basically already halfway overclocked which is why they overclock less. as lithography gets smaller you can't afford to go faster without extreme cooling. k stands for kill mode.

I have a old NON-K cpu (i7-4790) and I really regretted it now. Wish I would of got the K series because right now I would be able to over lock it abit to get abit more performance. Though might have to upgrade soon.
