The Core i7-8700K is one of Intel's high-end Desktop processors. It was released in 2017 with 6 cores and 12 threads. With base clock at 3.7GHz, max speed at 4.7GHz, and a 95W power rating. The Core i7-8700K is based on the Coffee Lake 14nm family and is part of the Core i7 series.

Core i7-8700K is also the successor of Intel's last gen Core i7-7700K processor that was based on the Kaby Lake-S and 14nm process and was released in 2016.

What this all means is that the Intel Core i7-8700K is an absolute beast when it comes to multi-threaded workloads, especially at this price point. If you're counting on doing some video editing or compiling one hell of an Excel spreadsheet, you're going to see firsthand a performance boost with the Core i7-8700K.

Bear in mind, however, that if you already have something like the Core i7-7700K, this generation doesn't offer the biggest boost in performance. You might want to wait another year or so before dropping a few hundred bucks, or even opt to splurge on a higher-end but pricier chip.

So which should you buy? Let's get that out of the way. Before this comparison review we updated our Best CPU feature and we said you should go with the Ryzen 7 2700X as it comes with a better stock cooler, can be overclocked, and the AM4 platform offers a significantly better upgrade path.

Now the biggest question is can Intel’s Core i7 processor play games? The answer is simply yes as it got a respectable gaming score of 91% in our benchmarks.

Regardless of those external factors, the Core i7-8700K proves it has the chops to be your main gaming system and a just as effective media creation platform – two things that are becoming intrinsically connected in this age of live-streaming, eSports and uploading gameplay videos.

That said, to squeeze out all the potential of this surprisingly potent high-end chip, you’ll want (and need) to splurge on an enthusiast-grade Z270, Z370, Z390 motherboard.

Fresh from a successful roll-out of mainstream Core i7 CPUs, Intel's attack on AMD now extends down into the high-end with its Core i7-8700K processors, which the company is making available as of Oct 2017.

Which GPU to Pick for Intel Core i7-8700K

Below is a comparison of all graphics cards average FPS performance (using an average of 80+ games at ultra quality settings), combined with the Intel Core i7-8700K.

Should I upgrade my i7-8700k processor to a better one? I also have a rtx 2070 super as my gpu. Any help?

AlexTheTimid July 23, 2020

Are you experiencing performance issues? If not then I’d stick with what you have. If you just want to upgrade to have the best I’d still say don’t. Wait until the new graphics cards drop this fall and upgrade then.

squidbrand July 23, 2020

What's the performance problem you're having with the 8700K?

If you can't answer that question, the answer is no.

-UserRemoved- July 23, 2020

You upgrade your processor when you feel it is performing less than ideally, according to your standards.

Do you feel like it is underperforming?

TheGamingJoeker July 23, 2020

well I want to get some better performance on my pc when playing games but I think I will stay with my current processor thanks to your guys help

TankerD18 July 23, 2020

No, unless you are doing some serious workstation shit and it's not keeping up. That's an i7 that's barely two years old. Unless games suddenly start cranking on the processor harder than the GPU, or if graphics cards (and games) suddenly become so advanced that a chip like that can't keep up with the GPU, that processor should be more than enough for gaming for many more years.

vasilixx July 23, 2020

Depends on your workflow, if all you do is gaming, photoshop, and some light video editing(1080p/4k) then there is no reason to do so. For programing and other cpu intensive tasks then I would recommend to get a ryzen 3000 series, as high as your budget can afford(though you will need to get a new mobo, but that is also true if you go for intel 10gen). Getting an intel 9gen (i9-9900k for example) doesent give you a big enough performance boost in my opinion, and the same also goes for amd if your workflow mainly requires single threaded performance.

TheGamingJoeker July 23, 2020

do you think the next line of graphics cards will improve my performance quit a bit? I am a gamer btw.

evicous July 23, 2020

It's essentially the exact same processor as an i5-10600K, which is basically a chart topping CPU. Everything else better is... Debatable at best. Your GPU is the highest end card I'd personally buy before price/performance completely goes into the stratosphere.

Wait until the new GPU and CPU launches hash out for sure.

Looking for ATX or micro atx, and would be pairing it with a 980ti

n7_trekkie August 01, 2020

you want either a Z370 or Z390 motherboard, but the latter will be easier to find because z370 is discontinued. watch these videos and pick whichever strikes your fancy

Gr_z August 01, 2020

all these boards are 200+ CAD I'm not sure i'm comfortable spending this much at this price range, I was hoping to go max 130$ so that my experience upgrading to ryzen 4xxx wouldn't have too much money going to waste

i7 8700k help

my i7 8700k got only 5600 at 3dmark test, whike the average score is 7800, why is that? is it broken or something?

RedeyeAEB August 06, 2020

There could be a variety of things that might be causing this. Check your thermals, maybe run again with task manager open to see if there's something taking resources from the CPU or if it's even reaching the proper clocks.

You could always try other benchmarks that test differently to see if you can narrow down an issue - I've always preferred Cinebench just cause it happens to be an accurate indicator of my workloads (lots of data processing). If I recall 3dmark tests a couple of factors so maybe see if you can get a breakdown of parts with your current benchmarks.

There's so much that could go wrong, best of luck in troubleshooting. Personally I suspect thermals as that's generally the easiest thing to go wrong, but there's so many other options

XMP Help, Please? z370 8700k

So i'm having trouble getting XMP to stick... my system does not want to boot when I enable XMP in the bios ( it just boot loops until I take out the CMOS battery):

i7 8700k (stock)

z370 Aorus Gaming 5 (bios f14)

I was able to manually type in the timings but had to drop the frequency to 3400mhz... is it worth tweaking this any further? Ideally I'd be running the RAM speed I paid for... but I understand that XMP is not guarantee.

Kit: G Skill Trident Z NEO 3600 16-19-19-39

I just tried booting at 3500mhz but not luck.

T-topology mobo + 2x dual rank dimms = low max memory clock

cun398380 June 08, 2020

thanks for taking a look!! Really appreciate it : )

Maybe I should settle for that speed and try to lower the timings?

For what it's worth, I was on a previous bios and when I initially installed the RAM with that bios I had similar booting issues but after a CMOS clear it somehow booted to it's XMP speeds. It was indeed running normally before the GPU troubleshooting began : /

DrVanilla1997 June 16, 2020

Silly question, I just glanced over everything, any possible chance that your mobo might not support these speeds?

edit: nvm looked up the mobo looks like it supports up to 4133

cun398380 June 14, 2020

yeah it braggs about that on the box : /

Don't know what else to do... I think it may have something to do with these RAMs "being for AMD"

U1traViol3t June 18, 2020

do you have the sticks in slots 2/4?

check your motherboard manual for the populate first slots aswell.

grumd June 24, 2020

Do you have an option to try this RAM on a different PC?

Did you try raising VCCIO and VCCSA (System Agent Voltage)? Maybe to 1.2 or something? It helps with RAM stability.

Here's a sample table from a guide: . Guide link if you need it.

cun398380 June 24, 2020

I just built two PCs for family members so i do not have that option atm...

As for VCCIO/VCCSA, I have never really heard of those options so I have not touched them. Do you mind explaining what those do?

Edit: For what it's worth, I was on a previous bios and when I initially installed the RAM with that bios I had similar booting issues but after a CMOS clear it somehow booted to it's XMP speeds.

MagicOrpheus310 June 26, 2020

I have 3200 tridents in a z270 with a 6700k and it has never liked xmp! Just seemed to fuck with things, swear I should have taken a photo, but one time it auto adjusted them to 5100mhz!! I changed it back before booting it though! But yeah I found using Ryzen dram calculator (even though I'm using Intel) and that really helped!

cun398380 June 22, 2020

the bclk is probably set to Auto, I can check that though.

I did update my bios, previously i was on f5 and when I initially installed the RAM with that bios I had similar booting issues but after a CMOS clear it somehow booted to it's XMP speeds.

Only reason I updated the BIOS was because I was having massive GPU issues which I have concluded is likely a faulty card...

Please help with i7 8700k

I don’t know if this relates to oc but I’m a beginner and any help would be really appreciated. I recently upgraded my motherboard and ram. My cpu which used to run at 4.2ghz started running at 4.36ghz, and I started experience a few crashes/freezes. Since I have a single air cooler my friends said it was an overheating issue. Now I’m using throttlestop to disable turbo and my cpu runs at 3.7ghz. I was wondering if I could get it locked at 4.2ghz like before? Ty for reading

TedThePenguin July 11, 2020

you should be able to reach 4.8 with no issues on air

gt_addict July 16, 2020

Did you change any settings to get it to run over the turbo freq? If so undo what you did.

If you didnt then you can manually set the all core clock to 4.2 in the bios.

8700K OC help


I am very new to overclocking. I've been trying to OC my 8700K to 4.9GHz (can't even get to 4.7GHz) but was not successful. I was wondering if you could guide me or let me know if I am missing some settings.

My setup:

  • NZXT H200i case

  • Intel 8700K

  • Kraken X62 liquid cooler

  • Trident-Z 16GB (8GB x2) 3000MHz RAM

  • Corsair HX750i PSU

  • Asus Z370i mobo

  • hwinfo64 for temps

  • CPUZ for Vcore (cause hwinfo64 doesn't list vcore for some reason)

Here are the UEFI settings and below are the voltages, multipliers, and LLCs I have tried that haven't worked:

Multiplier VCore LLC 49 1.31 5 49 1.32 5 49 1.33 4 49 1.33 5 49 1.33 6 49 1.34 4 49 1.34 5 48 1.32 6 48 1.33 6 47 1.31 6 47 1.32 6 47 1.33 6

With prime95 v 26.5, some combinations were able to pass first round of tests (10 tests per logical core) but as soon as the second round started, the computer either froze or BSOD'd. Temps also got to 99C when the second round started with voltages higher than 1.32v.

ttppx July 31, 2020

I couldn’t comfortably do 46 with my 8700k until I had it delidded. Now I run 49 with 1.32 ( kinda high ) but the temps are mid 70s with anything I do.

grumd July 31, 2020

Don't test with Prime95. It will overheat your CPU because it tortures your L1/L2 caches in a loop. It's not any close to realistic.

Use OCCT (large dataset, AVX2) for stress testing. My 9600K runs at 5.2GHz, -1 AVX offset, at 1.42v (drops to 1.38-1.4 under load). Using an air cooler, Dark Rock Pro 3.

It instantly reaches 99C on half the cores when running Prime95 small FFT, or when running OCCT small dataset with AVX.

But in realistic workloads, like gaming or video encoding it doesn't exceed 70-80C, which is completely fine.

You can try running 1.38v with some vdroop to 1.35v or something and see how far it gets you. Your cooler is very good for the CPU, you shouldn't have any issues. Just don't use Prime95 small fft for stress testing.

Also, if your VCCIO and VCCSA are on Auto, set them manually to 1.1v, might improve thermals a bit.

Thanks for your response. In one of the scenarios where prime95 failed, I also tried my current encoding application (Hybrid) and temps got dangerously hot around 95C.

i7 8700k boiling hot please help

After weeks of running at 85-95 degrees Celsius and experiencing fps drops I still don’t have a solution. I have used throttlestop to disable turbo and run at 3.7ghz but that doesn’t lower temps, nor did cleaning out my pc. I have 1 cooler master radiator and 1 case fan. Should I invest in an aio or buy another case fan? Any other solutions and help would be greatly appreciated, thank you.

So how exactly does your pc layout look? Like is the fan attached to the, I'm asssuming, radiator? With one intake?

I use the ARCTIC Liquid Freezer 360 with my i7 8700k. Temperatures are a cool 54degC with no issues. What are you using to cool the processor? If air cooled have you checked the blades are not blocked with dust? If using aio can you check if the pump is connected and recircing?

Could you post pictures, so we could see the cooling setup and fan configuration in detail?

get a noctua u12s as a cooler keeps my 9900k at under 50c while heavy gaming.

Pics are pretty blurry/grainy. Does your CPU cooler have a fan attached to it? If not, get on that right away.

You'll also want to put an exhaust fan at the back of the case.

Need to post better pics if possible to show fan layout inside.

Did temps just start spiking recently or it's always been like this? Did you reapply/apply thermal paste? Good contact between radiator and cpu? Enough intake/exhaust fans?

help-me-build-lit-pc July 28, 2020

Started recently spiking after upgrading motherboard to z390

Do you have a fan mounted to your radiator? Tried looking at the pictures but couldn't see if there was one mounted to it.
