Intel Core i5-11400F

[oxrufiioxo]

Looking at the Gigabyte B560 D3H, as I need a legacy PCI slot. Would it's 6+2 power phase be able to handle the 11400f without power limit?

Probably not 1/3 of the cpu portion of the vrm isn't even covered by a heatsink..... That board looks like a stock only affair.

By the looks of it I'd think the VRM's on that board would get pretty warm. It's more of an entry level board by the looks of it.

Thanks for the quick replies! I was planning to use a high airflow case with a couple of 140mm fan blowing down on the mb, but you're probably right this isn't a good idea.

What are you planning to run on it? Unless it's full load 24/7, don't bother worrying about the VRMs?

It's going to be for a music production PC, that's why I'm looking at this model as I need the PCI slot for my soundcard. Rocket lake is interesting for me as well as the software I use supports avx512. Won't be running it 24/7, but will be pushing on certain projects.

Very interesting, AVX512 can certainly push power consumption high. Guess you just have to try, and it's not like you have an alternative? Worst case is you have to limit the maximum power limit a bit, should still be good, especially with AVX 512. Which software is that?

 

[Mplay020]

Thanks again for your feedback, highly appreciated. The software is from a company called Acustica Audio. Their technology samples hardware gear and uses quite a bit of cpu. When avx2 was introduced with haswell it was a nice performance increase but I had just bought a 4c/8t Ivy Lake Xeon. Ideally I’d like to get double the performance compared that without breaking the bank

I don't think you'll want it unlimited power unlock. I tend to think that is bad for any system that is capable of over-stressing the cooling solution, and the 11400 can push 250W under synthetic loads. You may never have that scenario, but there's no point in leaving the power limit such that it could happen.

Which means you'll need a 3rd party air cooler. I wouldn't spend the $45-$80 on the models most review sites use (Brands like noctua, BeQuiet!, and so on) unless fan sound under load is a major factor, but it's certainly worth $25 (IMO) to push PL2 to 100W and beyond.

Here are a few cheaper options that I know are popular, the first one I can vouch for as I ran it at 160W PL2 with a 10850K, the other two look to be able to handle 125W or more :

Hyper 212 is pretty much a staple it seems :

So is Gammaxx, this one says up to 130W :

Definitely won’t be using the stock cooler after reading this review

Curious, what exactly from their product stack supports avx512? They seem to have a number of products. Thanks.

Anything core 16 and up is. Coffee pun is free and should support avx512. You do need to register and install through their Aquarius app. And of course you need a DAW to load it in. Reaper has a fully featured trial version and a small footprint if you want to test it out

Any thoughts on the 11400 at 40/41 degrees under load, whereas the 10100 came in at 48 degrees? I opened the 10100 review and saw the Noctua cooler used was the same. I'm assuming fan RPM curves were also the same? The 11400 evidently uses more watts, even at stock which arrived at 40/41 degrees. Is the heat simply released in a way that is more conducive for cooling? I ask as temps are an important consideration in my potential build due to wanting to use an enclosed, sound-reducing case. So the lower the CPU temps *and* RPM required, the better.

11 series all have solder, hence transfer heat more efficiently than 10th gen except the higher 10th gen models (K, maybe some non K not sure).

Think of it this way. You've got a heating pad (stove top). You put a piece of insulating material like ceramic on top of it, then put a pot of water on top of that. It'll take a long time for the pot to start boiling, and the heating pad will get pretty hot.

Now do the same thing, but instead of an insulating material like ceramic you put a thin piece of aluminum foil on top of the heating pad, then put the pot on top of the aluminum foil. The heating pad will x-fer its heat to the pot much quicker.

The example is a bit hyperbolic but it's the same principle, Intel improved the heat transfer rate from the chip to the heat spreader hence to the cooler. This is why the 10th and 11th gen chips generally run cooler than Zen 2/3 despite pulling more power, note that only some of the 10th gen have had improved heat transfer - mostly the high end and K series - not the low end models like the 10100. The power and heat is still being generated, it just transfers to the cooler much more efficiently.

 

[HenrySomeone]

What Randall says above, I might only add that at stock, 11400(f) uses only a bit more power than 10100, yet its die size is considerably larger (for some reason I can't seem to find exact numbers for 11th gen 6 core parts), which means that the thermal density is actually lower and the heat can therefore pass through the IHS and into the cooler more easily resulting in lower temperatures.

 

[Why_Me]

My gripe of the day: Why is it that North Americans are getting screwed on the new 11 gen boards? I posted a build here using a French PC hardware retailer and an Italian hardware retailer on another site and both of those online retailers had more and better boards than they offer in NA. This is some bs.

Distributors getting better margins in other regions because of tariffs, maybe? But seeing as NA has a tendency to get a better deal vs. other regions most of the time, maybe we shouldn't begrudge Italy and France their good fortune.

You might be right with the bolded part, but I'd give my left nut to be able to get my hands on a few of those boards they're offering in Europe.

 

[tempquestion]

Thank you both for explaining those details. I'm considering the i5-11400 for a quiet build intended primarily for web browsing, writing, etc. I'm looking into Pure Base 600 as the case, and Dark Rock Slim as the cooler. The case has minimal airflow. Do you think with low to moderate case and CPU fan RPMs I'd be able to keep the CPU temp at or under 60 C under my mild "load"? Ambient temps around 24 C. I know there are many factors here. Thank you for providing any feedback that you can.

Running the load you describe with that cooler, I imagine it'll be around or under 30C most of the time.

Review here at TPU shows running blender as a load, stock i5-11400 with DDR4-3733, only hit 40C with a Noctua NH-U14S.

It is the coolest running chip on their chart in that relatively stressful load :

 

[Tsukiyomi91]

AMD got nothing to compete in the under-$200 range. Even the former R5 3600 is no longer in that space after its price has gone up to $240+ while getting kicked around by the i5-11400 and F-variant in gaming performance, at stock settings. And I can bet to you that Intel has more stock than AMD right now, even more so that higher end 11th Gen models are getting price cuts like the i7-11700K.

with 65W TDP (which is roughly about 70W+ power draw under full load), it's far more efficient and far more cooler than the 11600K. Sure there are some games that takes full advantage of the 11600K's higher boost clocks but that's it. I doubt people want to spend $280 for a hot & power hungry chip that's roughly 7% faster than the 11400 and its F-variant when they see the benchmarks.

Hi, i've just buy à 11400f with a b560i strix and 3600Mhz ddr4 ripjaws.

I had à 4790k running at 4,6Ghz with z97i plus ddr3 sniper 2400 Mhz with negative offset vcore at 0,060. Power draw was above 60/70 Watts in msi afterburner.

MB CPU was/are paired with à 2080ti.

In 1440p games, there is no real (for human eyes) différences except with heavy multithreaded games as RDR2 (20% better) and less low frame rate.

11400f @ 4,3 just do the same gaming job as 4790k @4,6 with 20 watts less power consumption.

i just earned 2 more cores and 4 more threads.

In application, 11400f is just so much more powerfull.

So, if i have to do my story again, i'll Never bought 11400f... especially for gaming. There is no improvment.

Hope that will help you.

 

[HenrySomeone]

Well, no huge surprise there - at 1440p with settings probably cranked to the max, 11400f won't show that much difference compared to properly OCed and tuned 4790k (like yours) using "only" 2080Ti. The most noticeable will be better 1% lows just like you mention. Just goes to show what a great purchase the 4790k was for a gaming oriented build back in the day...

 

[Tsukiyomi91]

but it shows you that the 11400F runs cooler & uses much less power (on stock) than a 4790K that runs at a higher boost clock (after tweaking & OCing) all the while gives you better 1% and 0.1% lows. I rather have the extra cores, threads and IPC gains. Manual OCing is dead anyways.

Yes, that is right, but, 7 years separate those 2 cpu. In gaming terms, with the uprgrade from 4790k to 11400f, i've just spend/loose my money for nothing.

Conclusion, dont move to 11400f if you come from old i7 4790k.
