i7-6700K
  • The i7-6700K has higher Level 3 Cache. This is useful when you have substantial multiprocessing workloads, many computationally intense simultaneous processes. More likely on a server, less on a personally used computer for interactive desktop workloads.
  • The i7-6700K has more cores. The benefit of having more cores is that the system can handle more threads. Each core can handle a separate stream of data. This architecture greatly increases the performance of a system that is running concurrent applications.
  • The i7-6700K has more threads. Larger programs are divided into threads (small sections) so that the processor can execute them simultaneously to get faster execution.
  • For some games, a cpu with a higher clock speed, or in a technical name IPC (Instructions per clock), has better results than other CPU's with higher core count and lower core speed.
  • The i7-6700K has a higher turbo clock boost. Turbo Boost is a CPU feature that will run CPU clock speed faster than its base clock, if certain conditions are present. It will enable older software that runs on fewer cores, to perform better on newer hardware. Since games are software too, it is also applicable to them.
  • The i7-6700K has a smaller process size. The faster a transistor can toggle on and off, the faster it can do work. And transistors that turn on and off with less energy are more efficient, reducing the operating power, or “dynamic power consumption,” required by a processor.
Pentium G640
  • The Pentium G640 is more power efficient and generates less heat.

i7 6700k OverheatingI just got a new i7 6700k replacement. My old one was running at 95c during a lot of games. I tried running prime 95 with the new one and all my CPU temps go to 100c immediately. I have a H100i so my temps should be no where near that I would think?

Glad that worked for you, which proves your H100i is functioning. Fortunately, Corsair warranties your cooler for 5 years, so when the pump does fail, you should be able to RMA the unit for a replacement.Although the description in Prime95 v26.6 for Large FFT's says "maximum heat, power consumption" it actually refers to total system, CPU and memory, so that description is a little misleading. Later versions of Prime95 corrected those descriptions.Small FFT's is the ideal test for CPU temperature because it primarily tests the CPU, and it's a steady 100% TDP workload. Prime95's default test, Blend, is a fluctuating workload for testing memory stability, and Large FFT's combines CPU and memory tests. As such, Blend and Large FFT's both have fluctuating workloads which aren’t well suited for CPU thermal testing. During certain test sequences, Small FFT's maintains a higher CPU workload than Large FFT's.Here's an example:The "Charts" in SpeedFan span 13 minutes, and show how each test creates different thermal signatures. http://imgur.com/AV0iCxD.jpgShown above from left to right: Small FFT's, Blend, Linpack and Intel Burn Test.Note the steady thermal signature of Small FFT's, which allows accurate measurements of Core temperatures. A steady 100% workload is crucial for thermal testing.Also, downclocking to 3.5 GHz is a little drastic. It was sufficient when you changed the voltage, which has the greatest effect on Core temperatures. You might want to restore your settings to stock and change just the voltage to the lowest value that's stable, then run P95 v26.6 Small FFT's and see what you get. I think you'll find that Core temperatures are around 80'ish, which is still OK.The best solution is to delid your 6700K, or have it done professionally. You can safely delid by using a “delidding tool” such as the Rockit 88 - https://rockitcool.myshopify.com/Silicon Lottery - https://siliconlottery.com/collections/all/products/delid - is a company that tests, bins and sells overclocked, delidded "K" CPU's. They also offer delidding services, and give the following figures on how much Core temperatures at 100% workload are improved by delidding:7th Generation ... Kaby Lake X - 12° to 25°C7th Generation ... Kaby Lake - 12° to 25°C6th Generation ... Skylake X - 10°C to 20°C6th Generation ... Skylake - 8°C to 18°C5th Generation ... Broadwell - 8°C to 18°C4th Generation ... Devil's Canyon - 7°C to 15°C4th Generation ... Haswell - 10°C to 25°C3rd Generation ... Ivy Bridge - 10°C to 25°CBeware that delidding will void your warranty.I've delidded many processors including the 6700K, and the results from Silicon Lottery shown above are true. In my opinion, since Intel stopped using Indium solder and began using various thermal compounds on 3rd Generation and later processors, those of us who are overclockers or just temperature conscious, are unfortunately left with few alternatives to chill our chips. Delidding is still the best choice because it's the most effective means by which to seriously decrease Core temperatures.2nd Generation Sandy Bridge was Intel's last thermally predictable, well behaved processor. As an overclocker, I've since delidded every processor I've owned from 3rd through 7th Generation (except 5th Gen - never owned one), and recommend it highly. It's the only sure method to gain positive control over your Core temperatures.CT

Are these safe temp for I7 6700KHello everyone,I overclocked my PC from 4Ghz to 4.6Ghz and runned system stability test (Aida64) and the temps are as you can see below i could not add picture so i typed it over (sorry new to the forums).Specs:CPU: I7 6700KGPU: Asus ROG GeForce GTX 1060 Strix OC 6GBMotherboard: Maximus VIII RangerCPU Cooler: Be quiet Dark Rock pro 3Ram: HyperX 8GB CL15 17-17 (2 of 4GB)PSU: CoolerMaster G750MHDD: Segeat 7200 rpm 1TBSSD: Samsung pro 850 512GBare these temps good or are they high?Motherboard:Current temp: 33ºCMinimum: 31ºCMaximum 34ºCAverage: 33.3ºCCPU:Current: 66ºCMinimum: 31ºCMaximum: 65ºCAverage: 64.4ºCCPU Core #1:Current:65ºCMinimum:30ºCMaximum:84ºCAverage:64.7ºCCPU Core #2:Current: 66ºCMinimum: 28ºCMaximum: 83ºCAverage: 66.9ºCCPU Core #3:Current: 56ºCMinimum: 26ºCMaximum: 85ºCAverage: 65.2ºCCPU Core #4:Current: 65ºCMinimum: 27ºCMaximum: 78ºCAverage: 60.2ºCCurrent temps are different they are between 60 and 79 but they get higher then lower. Thx for the help,Sorry for my bad English.

Your results look nominal.The processor under load will shut down or reduce the clock if it senses a dangerous temperature.That is around 100c.Under normal operations, I would think 75c. is perfectly fine.The thing to watch is Vcore. Thjat is what drives temperature up. Do not let it go past 1.4v.Monitor with cpu-Z,FWIW: As of 12/04/2016 What percent can get an overclock at a somewhat sane 1.4v Vcore.I7-6700K 4.9 5%4.8 21%4.7 64%4.6 96%

I7 6700k or 6800kI can't decide which one to get. I am a big gamer and I have a triple monitor setup with two 1080p and one 3440x1440p ultra wide. I also have a gtx 980 and will be upgrading to a gtx 1080 or 1080ti when it comes out. I normally have some chrome tabs open. Maybe YouTube running, headphone software and sometimes a mine craft server, and skype. Basically I'm looking to future proof myself with what I do. I don't want a bottleneck 1 year from now. I'm trying to get the best fps possible without lag. So which one is better? Thanks

It's difficult.The 6800k has 6 cores with hyperthreading with more l3 cacheThe 6700k has higher clock speedPrice/performance the 6700k winsThe 6800k is just a bit too pricy for it's performanceHowever if we're talking about a 6850k and price isn't that big of an issue things are different.Dx12 is optimised for 6 cores and the higher clock comes handy.So overall it comes down to your budget.

i7-6700K Overclock IssueI have an i7-6700K in a Gigabyte Z170X Gaming 7 rev. 1.0 motherboard with bios version F22f (the latest version as of this post) and a Cooler Master Hyper 212 Evo air cooler. The board has overclocking presets instead of standard multiplier and voltage controls, and no apparent way to manually set up an overclock. Every time I try to push my CPU over 4.4GHz I get a BSoD with error code CLOCK_WATCHDOG_TIMEOUT, which is a communication error between CPU cores. Is this an issue with the motherboard or something else? Also, is there a way to get around the presets to customize the CPU voltage settings?Update:I have tried 4.5 GHz again and it seems that the CPU is stable except when running certain video editiing and AIDA64 benchmarks, which produce various blue screens with errors such as IRQL_NOT_LESS_OR_EQUAL and KMODE_EXCEPTION_NOT_HANDLED.

Another i7-6700k Temperature ThreadHey everyone,I know this will be about the 1,000,001th time this has come up, and I am sorry. I searched the forums for about 4 hours but did not find my unique situation.Build:CPU: i7-6700k 4.2GHz (Turbo Boost)GPU: Asus GeForce GTX 1080 8GB StrixRAM: G. Skill Ripjaws 16GB DDR4-3000Hz (4x4)PSU: EVGA SuperNOVA P2 650W 80+ PlatinumMobo: Asus Maximus VIII FormulaCooler: Corsair H115iCase: NZXT Phantom 820 w/custom side panel w/o side intake fanFans: Cougar - CFD14HBW 73.2 CFM 140mm x6 (3 intake, 3 exhaust)Resolution: 1920x1080Monitors: 1, @144HzAmbient Temperature: 20-23CCPU Idle Temps: 23-28CSo, in my situation I'm not sure if it's my cooler, or my voltage, or nothing major to worry about. I built my PC myself and it's my 5th build, so suffice it to say I'm fairly confident in my skills. I do believe my cooler is seated properly.I know that my case is cooled just fine, as my GPU stays around 60C, and never breaches 65C in any given situation. In this scenario, it sat at 58C the entire time.While gaming, I've checked my max in Corsair Link and have seen a height of 90c. So I downloaded MSI Afterburner and used the in-screen display to view my CPU temperature in real time, as I know spikes occur.Game Tested: The Evil Within 2, all ultra settings, full screen, 1080p resolution.During my hour and a half of play time, I mostly hovered around the 65-75C range. I did see one spike to 85C for a mere second, though spikes to 80C occurred multiple times. Temps went down to the mid-high 70's thereafter. This was mostly in open world situations, and in closed world I saw temps from 58-65C.Checking my cooler temperature, it did go up to 48C, and it's running at the max of 3090 RPM, with fans set to 100% (960 RPM). I'm not sure if this temp should be higher, given the temperatures my CPU reached.Checking my voltage, I have seen it go up to 1.47. I am fairly certain that I have gone into the BIOS in the past and set this to 1.26 or thereabouts, as I have read that most i7-6700k CPUs are notorious for being way too generous with the voltage. My CPU is OCed out of the box, I did not do it myself.I do know that 80C is safe, and the thermal threshold for this CPU is 90C. My CPU has never, to my knowledge, ran at any given length of time at either of these temperatures, but rather experienced one or two second spikes to those degrees.My questions are:1. Should my cooler temperature be higher, and if it should be, do the low temps of 48C indicate it's either faulty or not seated properly?2. Should I adjust my voltage? If so, what should it be set at for 4.2GHz?3. Should I just stop worrying about my system's longevity, since I mostly hover between 58-75C while gaming?Cheers!

I7 6700 vs i7 6700k (K vs non K)I can't find a comparison between the both cpu.. The difference of price is around 50-80 dollars. Which is huge, I'm not fan of overclocking but if the performance gain is huge I will buy the K editionI read somewhere that you can overclock the non K edition but there are no guides anywhere even google doesn't help.

MS-7850 With Intel Core i7 6700k?Hi I want to upgrade my processor mainly for gaming. My current processor is an Intel Core i5-4690k And that runs with 16gb ram and a AMD Radeon R9 390 graphics card I would like to upgrade the processor to the intel core 17 6700k Will that work with my current motherboard?
