This thing is at 5.1Ghz on all 8 cores just using my motherboard's auto-OC ( I don't know how to OC myself ). Things are instant. I can stream code from my brain to my IDE without ever waiting for the keystrokes to appear, close and open endless tabs instantly without that nasty close lag you feel on OS X or slower CPUs on Windows, and do pretty much anything imaginable. 8 cores is a good sweet spot for general use, coding, and gaming. Anything more is awesome, but likely 100% imperceptible to anyone not doing rendering or a few other thread-dependent workloads. If you don't know that you need 12 cores, you don't need 12 cores, and you can probably get by with 6.
Windows also *FEELS* 200% faster when it doesn't have to flow through integrated graphics, this processor, therefore, is the god of desktop right now, benchmarks be damned.
Whatever the tech was that Intel introduced in either the 8th gen chips or 9th gen that lets the CPU get to its turbo faster is the thing you don't get on AMD, so how fast your computer *feels* is still, unfortunately, better on Intel even despite comparable single-thread benchmark results ( which don't represent how long it'll take for your computer to *feel* like it's responding to you ).
Conclusion: If you consider yourself someone who thinks or talks at a normal, casual pace, you're better off getting a cheaper AMD CPU because you won't necessarily perceive the benefits this chip gives you. If, however, you use a computer fast, and are a zippy little mofe, this CPU is currently the best out there capable of getting the highest single-core speeds which will make all the difference in how fast your computer feels.
Also, I thought this chip was supposed to handle heat better than the regular 9900K. I have a very basic ekwb cooling loop from one of the premade kits and I am not confident as under stress testing all threads using cpu-z benchmark, I instantly spike to 95c and then within 30-45 seconds of constant stress testing I steadily will creep past 102-104c. Maybe I just really lost the silicon lottery but to me it’s kind of unacceptable to release a processor that either requires that much cooling capacity at optimized default levels. Perhaps when they finally do shrink to the smaller 7nm die, maybe then they will be able to have processors with this many cores and threads and not have them heat up like a mini Chernobyl on the cpu. The only plus side is, when I do get to use it for the brief 5-10 minutes.. 15 tops a few times on a cold night, the processor is indeed very responsive. It’s too bad to be able to truly use all this power you need a computer that frankly is a few thousand outside of my budget.
Amazon return was very easy.
I now have a i9 9900K (not KF) and I love it, would rate this 5 stars if it had not been D.O.A..

Was initially after a 'k' but they were out of stock and the KF was a little cheaper. Have heard reports that they may run a fraction cooler and may overclock better.
It has no onboard graphics, but seriously, who buys a 9900k and doesn't use a separate graphics card anyway, and more than likely has an old spare kicking around.
9900 was probably overkill for my current useage, but the performance boost and longevity of the setup made it better value than a processor upgrade on my old board would have.
I'm using a BeQuiet dark rock 4 air cooler and it has no problem keeping temperatures in check even during extensive stress testing with a mild overclock. My build is pretty stealth and I wanted a virtually silent pc at idle so didn't want the constant whirr of water based cooling solutions.
I upgraded from a AMD ryzen 2700x and the difference is amazing well worth it.
The KF model is the same as the K model just without the iGPU not a big deal unless you like the backup of a n internal GPU in-case anything happens to your main GPU.
This 5gig overclock seems to be a gimmick to me ,I dont know why Intel didn't just sell it as a 5gig processor rather than call it over lockable.
Anyway as said the jump from i7 to i9 isnt really worth it for gaming ,and these run hot so dont skimp on cheap case if you're upgrading.
Obviously performance overall has increased I just wouldn't say for the cost that it's worth it.
Saying that I'm happy enough
+ 16 threaded with easily OC to 5ghz
+ Much cooler than i9 9700K (-15 degree difference on 5ghz OC!)
