The Core i7-10700K is one of Intel's high-end Desktop processors. It was released in 2020 with 8 cores and 16 threads. With base clock at 3.8GHz, max speed at 5.1GHz, and a 125W power rating. The Core i7-10700K is based on the Comet Lake 14nm family and is part of the Core i7 series.

Core i7-10700K is also the successor of Intel's last gen Core i7-9700K processor that was based on the Coffee Lake Refresh and 14nm process and was released in 2018.

The Intel Core i7-10700K is an absolute behemoth of a processor, as it absolutely should be with its 8 cores, 16 threads and high price tag. If you’re looking for the absolute best processor money can buy on a mainstream processor, then look no further. Whether you’re playing PC games or even doing hardcore video and 3D work, the Intel Core i7-10700K can handle them with ease.

What this all means is that the Intel Core i7-10700K 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 i7-10700K.

If you're mostly playing games on your PC, you will be happy buying either processor. Both proved to be solid options and are evenly matched with a slight advantage to the AMD chip if you don't tune up the Ryzen 7 processor. The base performance we showed for the Core i7-10700K can be achieved with $90 memory, while the Ryzen 7 3800X will require $110 - $120 memory in order to enable the frame rates shown here. It’s not a big cost difference and right now with anything less than an RTX 2070 or Vega 64 you’ll more than likely become GPU limited.

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 98% in our benchmarks.

Regardless of those external factors, the Core i7-10700K 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 H410, 4470, Z490 motherboard.

Critics Reviews

The Intel Core i7-10700K is an 8-core/16-thread part, a doubling in thread count over the 9th Gen Core i7-9700K, which is an 8-core/8-thread part. The L3 cache has also been increased by 33%, up from 12 MB to 16 MB. This is in fact an identical hardware configuration to the Core i9-9900K.
The Core i7-10700K leads in gaming, but cost-conscious shoppers may prefer Intel's own Core i5-1600K, which is a better value for lower-cost gaming rigs. This leaves the Core i7-10700K as a good ...

Title says it. I want to buy a i7-10700k and I'm tight on funds. Will the 212 EVO keep it cool? No plans to overclock.
Phaaze88 December 30, 2016

According to the above: no.
Even if you capped the cpu's frequency at its base(3.8ghz), that's still 125w max. The Hyper 212 is designed to handle up to - but not exactly, 150w.
25w of headroom isn't much to work with.

If you can't afford a decent 200w+ cooler for a 10th gen K SKU, I don't think you should be looking at one at all.

Hi, current I just upgraded to i7 10700k and I have confused to choose AIO 240/360mm. My case is DeepCool E-Shield:
  • Fan case: 120mm rear, 2x120 or 1x 140mm top, 3x 120, 3x140 (without CD rom) or 2x120, 2x140 (with CD rom) at front
  • AIO: 120/140/240mm top, 120/240/280/360 front.
+ Because some people said if put radiator at front with fan intake (fan in front of radiator) it can cool cpu good but drive, ram, graphic card will be warmer, many choose at top but my top only have 240 max so which AIO 240 can cool this cpu ? I use only stock for gaming, develop web, app, sometime use photoshop edit image for troll or make beauty
- Some AIO 240mm at my country:
  • Asus Rog ryujin 240
  • AIO Cooler master masterliquid ml240p mirage
  • AIO DEEPCOOL Castle 240RGB V2
* My system:
  • Mainboard: ASUS Rog Strix Z490-A Gaming
  • CPU: i7 10700k stock
  • PSU: Seasonic focus 650w 80+ gold
  • Graphic: ASUS RTX 2080Ti 11GB GDDR6 ROG Strix OC (Default not OC it)
  • Memory: 32GB kingston predator 3200mhz (2x16)
  • 1 ssd western digital blue 500gb, 1 hdd 500gb western digital blue and 1 hdd 2TB western digital blue
  • 4 fan case (1300±7%RPM, airflow 65.16CFM)
By the way my PSU can run it for long time ?
Phaaze88 December 30, 2016
It does, but it's usually nothing serious.

ML360R is middle of the road.

Dust is inevitable. Just don't go and neglect maintenance for a year or more, like some folks will do.

I7 10700k better than i9 9900k for gaming and recording?
GarrettL December 04, 2019
Gaming performance is almost the same. The 10700k would be my choice between the two.

Recently I upgraded my old system with a new CPU, motherboard and case. Unfortunately since then I have been having issues while gaming. Mostly after 10-45mins the PC instantly powers off and automatically restarts after a minute or so. The power button is unresponsive during this minute. Temperatures are pretty good, CPU sits at 40°C and GPU around 50°C. My guess would be problems with the PSU, but it was working fine in the previous build a while ago (never had crashing issues back then). The only change that I'm not sure about is the 8 + 4pin connector for the CPU. At first I added an extra cable to the PSU and connected them both. I read mixed results about the second 4 pin not being required so I tried both, but the PC crashed in both cases.

While upgrading the PC I re-used the (m2) drives, PSU, GPU and RAM from my old setup. At first I just booted my old startup disk and tried installing the new drivers. It worked but got me the same crashes. Now I'm on a clean install with updated drivers & windows and am still having the same results.

I checked all the cables, graphics card & ram is seated correctly. The only thing I can think of is that the PSU cannot handle the new CPU/motherboard/CPU cooler (with xmp enabled)? But I'm at a brick wall because I think 850w should be good enough right? Is there anything else I can try or check before getting a new PSU?

Thanks a lot for taking the time to read this!

Common causes of sudden shut offs/restarts, and what you can do about them:
1)Missing or corrupt Windows drivers
A)Make sure PC is clean - run antivirus and antimalware programs.
C)Reinstall Windows - especially after changing motherboards

2)Memory failure
A)Memtest86 free version:
It does take a few hours, so run it overnight.

3)Insufficient power supply
That's an old platform from 7-8 years ago. 5 year warranty. It was great budget unit back in the day - it's 'meh' now.
A)Replace it. That's all you can do here.

4)Overheating power supply - it refuses to turn on for a set period of time
Either due to fan failure, or the loads are simply too much for the internal components to deal with anymore...
A)Same as number 3.

Hi currently I have
  • Z490 i9 10900k or i7 10700k
  • 3 fan case (1 back, 2 top)
  • 1 AIO 360 (At front)
  • 1 RTX 2080ti
  • 1 samsung ssd 256 gb and 3 TB HDD black
  • Ram 8GB DDR4 (4x8)
  • 1 Headphone USB, 1 keyboard, 1 mouse
  • My PSU: Seasonic focus gold 650w
Is it enough i9 10900k or i7 10700k ? I don't OC use stock and use only single card.Thank you.
Phaaze88 December 30, 2016
Well, if you're REALLY not going to overclock:

320w on Founders Edition models - aftermarket models will typically have higher power limits.

That's 549-570w from the cpu(full load) and the gpu(founders edition).
Add up some of the other stuff... that's gotta be over 600w, full system load.

I'd say a 650w isn't enough. A 750w would be.
