I can cherry pick too! Wow it sure is worth almost double the cost for less performance than a $190 CPU:




But then you would be missing out on that 1% IPC increase!!! How could you leave that much performance on the table?!

The i7-7700K is like Listerine, the burn means it's working!
Sure, cherry picking, there you go:

https://www.hardocp.com/article/2017/04/11/amd_ryzen_5_1600_1400_cpu_review/4

that´s how you effectively test a CPU. Before you jump saying "no one plays at such conditions" let me remind you of 144hz and 240hz gaming, where all the fps are important.

Benchmark Scores Yes I am Intel fanboy that is my benchmark score.
:confused: How has this only become news? Seems something like this would have been before now. Or at least gotten a bit more exposure on the hardware sites. All the ones I frequent, have not seen mentions of this.
Exactly my point. My own 5.0Ghz 7700K never exceed 76c while sitting on a H110i. I do not plan to De-lid such a fine chip. Mine is sitting on Asus Maximus IX HERO.

Is sad how techpowerup is being so biased lately. Was my fav website. If you read rx580 review you will understand.

As for this "issue", do your research and you will find that making drama news from this is totally biased.

Quick tip: these cpu were launched almost 6 months ago.

Good luck techpowerup with your new direction. Thanks for everything. Cheers
Hey there Donald! See you are still making accusations without proof.

Plenty of people have already reported this issue. I would say it's your word against their's but you haven't added anything to the conversation other than "fake news!".

I understand how having your fan spin up to 2000rpm from 1000rpm would be annoying.
I had the same problem with my GPU until i hard-wired the fans.
In spite of what some people are saying in this thread, spikes like this are not normal and should NOT be tolerated. It's annoying as hell, especially with a loud-ass stock cooler.

So in your opinion running a bunch of incredibly old games that only use 2 cores is an effective test of modern CPU's? lol ok buddy. Please double check your link though, because even the R5 1400 pulls off 240Hz in Lost Planet. That means there is no discernible difference.

How about a game from this decade:


^Once again it isn't just about "Removing the GPU bottleneck". If it was just a gpu bottleneck, Ryzen would never take the lead. Yet here we are and Ryzen is a full 12% faster in 4K, and that is well past "margin of error". Ryzen is just flat-out better at processing high resolutions than Intel is, and in 1080p it's a laughably small difference.


If you do 240Hz 1080p gaming (which is ridiculous considering how few games support this framerate), then yeah get a stuttering 7700K.

Erhhh, what are you talking about?

If anything I sometimes get the feeling TPU is biased towards Nvidia. Overall though TPU is very fair, and in fact I would say they have become more fair lately.

Agree, people is 100% hyped to play at 640x480 with a 240hz monitor, i mean just imaginate play at 640x480 in a 4k 240hz, damn i men can just dream :( /s

On topic, yes its true than intel IPC push more fps but i havent see any 240hz benchmark review between ryzen and intel, and play CSGO at 240fps+ isnt big deal for ryzen too.

Any game supports 240hz, and it is miles better than 60hz or 144hz, specially for e-sports, period. You really want to know the percentage of gamers that use such high resolutions? Go n steam stats and check for yourself. Oh yeah I know that in 3 years many gamers will be using 4k, but in 3 years you will also have much better CPUs. And there isn´t such thing as "ryzen being better than Intel at high resolutions"; is all error margin, because GPU is strained on those conditions, not CPU. Prolly you would get the same results on 90% of the games, with an i3 + GTX1070 at 4k.

Agree, people is 100% hyped to play at 640x480 with a 240hz monitor, i mean just imaginate play at 640x480 in a 4k 240hz, damn i men can just dream :( /s

You didn´t get it. I´m not saying me or someone plays at 640x480, but if a CPU can provide you 30% more frames that can mean the difference between 240fps and 180fps at 1080p and medium graphic settings with a good GPU. That´s the whole point of these Hardocp benchmarks, so you can get an idea of the real percentage difference between the CPUs on game engines.

As for Ryzen and CS GO you are wrong again. 7700k at 4,6ghz provides you 350-400fps in any condition, while on Ryzen you are in the house of 200s, wich for CS GO e-sports is low. An overclocked 7600k for CS is better than Ryzen. Now talk about "the future of multi threaded games" that no one cares about. CS GO is the 2nd most played game on PC and e-sports, and will remain like that.

You need to open your minds and understand that each case is different. Ryzen might be fine for you, but Intel is better at 240hz competitive gaming, period. Wether you despise that kind of experience, that´s a different story. So just don´t come and say that everyone should get a Ryzen because Intel is not worth it etc etc. We all want different things from our PCs.

If someone wants e-sports, why would this person buy a CPU that is better for Adobe Suites, Blender and streaming? If someone wants producitviy why would he buy a higher priced quad core 8 threaded CPU? Simple maths. Keep being ignorant.

Given the duration of these spikes (on the order of 3-7 sec), it's possible the temp sensor on the chip is just close to a high-temp component of the core.

You jump from 0-100% load for something, either foreground or a background task. The core temp naturally jumps immediately, but it takes a few seconds for the heat to start to spread to the surrounding silicon and then the heatspreader. In that time, the local temp could get fairly high. If the sensor was far away from the core, you'd see a gradual increase then decrease. The closer the sensor is to the core, the more pronounced the spikes will be.

Mine was incredibly spiky when I had it. Far more so than any previous Intel chip I'd owned. The delayed spin up/down options in my Asus Z270 Prime seemed non-functional too, meaning I had to use AI Suite in the end to stop my CPU fan spinning up even when doing something like opening Chromium, as the CPU would spike from the high 20s to the mid-50s and trigger it. Load temperatures were okay (by Kaby Lake's standards) with an NH-U14S, but the fluctuations were annoying and one of the reasons I ditched it for an R7 1700.

@Bandalo this happens since Skylake gen on non K CPUs and on K overclocked CPUs with voltage set on AUTO or without an offset. These are not any news, is just an article to cause drama, because Techpowerup is like that now. Just need to pay attention to their last articles and reviews to conclude that, where a GPU that draws almost double the power and has a 5% increase in performance, is rated more than 9.0.

IF this was a real problem, it wouldn´t appear only 1 year and half after the release.

There was a time where this website was totally unbiased and my fav one to read about hardware. It isn´t like that anymore and isn´t only me saying it. Maybe I´m one of the few that bothers coming here to write it. Just pay attention to other hardware forums and you will see what´s happening with techpowerup.

Right now GamersNexus and Hardocp are 2 good unbiased websites that put the facts and the scientific graphs in your face, and you make your conclusions.

For having a 7700K and de-lidded I have not seen such a case in the proclaimed temperature spikes.

I ALWAYS have my temperature monitoring program on straight at boot up and haven't seen any problems here.

I was making my comments based strictly on the graphs provided and what I know of EE and heat transfer. I'm not saying there is or isn't a design flaw or problem. Honestly I'm quite sure the CPUs are perfectly fine, and it's probably more an issue with how the temps are being tracked than anything else. A 90C spike for 4 seconds isn't going to do anything to a CPU that's rated for 100C continuous.

Adjust your fans on a 10 second average of temp rather than the instantaneous temp, and you'd never have an issue.

I seen an Office PC with a i5 4670 non K running at 90º load for 3 years everyday with a stock cooler, and the cpu is still alive. CPU temperatures concerns on the internet are overrated as f, because people don´t actually experience the stuff before talking. Killing a CPU these days is so hard that you can´t even imagine, unless you mess with the pins.

So no, a sensor read error won´t kill your 350 bucks CPU. Nice drama tho

what would be funny is if all these guys didn't notice windows 10 updating in the background.

Same, I bought a 4770K on september 2013 and always with the stock Intel cooler, when gaming was as hot as 90ºC sometimes, man, it is still alive and running just like day 1, i have recently bought a CM 212 Evo for fun and overclocked the cpu to a decent 4.3 ghz and worked excellent, it can now avoid throttling thanks to the new cooler, i gave it to my father when i bought the new cpu on jannuary, the only reason why i bought an AIO cooler is to avoid throttling, not because it's going to die due high temp, having that obsesion with temperatures takes away the fun, being worried all time for such little things like that, i mean who keep these cpus for more than 4 years? and who does is probably a person who is not into that world of gamers or simply a very simple person, luckily my cpu doesn't get that hot, i have seen only a max temp of 73ºc on core 1 according to RealTemp and it's not concerning for me at all.

I.v just returned i7 7700 because of high temperature and voltage. Using i5 7500 which behaves much cooler , thank you.

I think what's going on is some of these motherboard bios over volt the CPU. For example my board at load feeds 1.35 v to the 7600k at stock and while encoding vids temps were in the mid 80s. If your concerned about temps steps to take are upgrade bios, manually dial in vcore at 1.2v and maybe update the ME firmware. Also had to upgrade the heatsink to a better one and put a high static pressure fan on it which saved about 7 degrees. Also going to get a better case all because of Kaby Lake. Dare anyone to run Prime 95 v 28.1 and report your temps. Prepared to be shocked!

Anyone remembers that funny looking Pentium (think it was 2 or 3, perhaps) that was put vertically, on a slot on the motherboard? That thing was constantly running at 90C, and was projected like that...

The 7700 and 7700k are not exactly "new" CPUs (meaning they have been available for a few months). Why haven't we heard of this before now?
It may be a bug on some newer BIOSes on newer kaby lake mobos, or it could be a silicon error that took months of use to show up.

So from the replies it might be an over-volting issue? Bumping the voltage drastically could definitely explain the bump in temps and could be related to software. Whether that is due to BIOS/microcode/whatever is to be determined though...

Well, no one here actually KNOWS. We're all just speculating based on some seriously limited data.
