Are Intel i7 4770K cooler than AMD FX-8350?

I've heard the Intel processors run cooler than AMD for the same load. If I switched from the FX-8350 to an Intel i7 4770K, would I see temps drop while gaming running the same heatsink/fans? Games I currently play are Call of Duty Ghosts and Battlefield 4.

What cooler are you running? Are you running them at stock speeds?

Stock, the 4770k had a TDP of 84W while the TDP of the 8350 is 125W, meaning the 8350 does get a bit warmer.

I don't think so, but from what I recall, AMD CPU's can't get as hot as Intel's before breaking.

Stock speeds. Good info on the wattage, didn't know they ran higher. I guess that pretty much means they will run a lot hotter than an Intel.

I read somewhere 54c is the highest an AMD 8350 is supposed to get for sustained periods. Wonder what the highest Intel is rated for?

they are pretty different to measure temps.. in AMD FX 8350 you should check for the CPU package Temps, in the Intel 4770K you should check for the individual CPU Cores temps.. the 4770K run way cooler than a FX 8350 at stock it have 84W TDP but thats due the increase of the iGPU power, running a discrete card they run like at 40W at stock turbo clocks under high stress test and the cores will run way hotter than the CPU package itself before it can even reach the max safe temp specified by intel in this case 72C for the Package and 105C for the indivual Cores...

as an example i will use my 3770K overclocked to a soft 4.2GHZ.. running crysis 3 which its very CPU stressing it draw 35-42W and temps are in the 55~58 peak hotter cores and average of 49C in long gaming sessions thats in the cores, but at that same times the CPU package barely touch the 42C line with average of 37C..

in the case if i can remember right the max safe temp for a FX8350 its 62C the package that will mark your temp limit.. most 8350 will start to throttle passing the 65C line..

EDIT: adding info.. according to AMD:

The maximum temperature for the FX-8350 CPU is 61.1C at Tcase. This is different from Tjunction (which the BIOS and programs like HWMonitor will report), and can easily be referenced through AMD OverDrive, or closely referenced through programs like CoreTemp/RealTemp. HWMonitor and BIOS software will report the Tjunction temperature which can be as much as 10C different from the Tcase temperature.

Tjunction shouldn't be ignored specifically, as a Tjunction temperature that is in the 70s is definitely cause for concern, even if the CPU is only in the 40s, as that could indicate a hardware fault in the socket that could start damaging hardware. The 61.1C limit is for Tcase, but Tjunction is good to ensure that there isn't any damage to the NB controller, socket, or memory controller. It's just less important than Tcase for actual CPU temperatures, but is a good warning sign for issues with the board or northbridge.

Intel's 72c is 10c more than AMD. That's a significant difference. I know for a fact my processor becomes unstable if it reaches temps above 60c, according to speedfan temp readings. At 65c expect lockups on the FX-8350.

I'm a little confused about Tjunction vs Tcase. Is speedfan reporting Tjunction?

Speedfan has two temps it reports, what I believe is chipset, and cpu. If I open (the board is Asus) Fan Xpert the temp it uses for controlling fan speeds is the same temp as Speedfan is reporting for cpu.

Tcase its the temperature inside the CPU package.
Tjunction its in fact a intel terminology a little bit adopted by AMD but with different results, in the intel side the Tj (Tjunction) its the operation temperature of the Cores Temps. its defined by intel as TJmax and its the trigger point when the processor shutdown to avoid damage in more recent chips they start to throttle a couple of degrees before TJMax. if 105 its the TJmax then the processor will start to throttle reaching the 100s and shut down if touch the 105mark..

in the AMD side are referred to the Socket temperature reported by the Motherboard socket sensor under the CPU.. anyway in more recent AMD Chips the temperature reported by programs its the Tcase. and thats what you should be looking for.. in olders chip the temperature reported to programs was the socket temp (or Tjunction). thats not anymore that way (as far i know, please someone correct me if im wrong)

in the Tcase side Intel chips run way cooler than AMD chips and can run 10C hotter before the throttle point.. however for the intel chips as i said the cores will reach faster the TjMax before the TcaseMax. in many case you can see a 4770k running at 90C the cores and the Tcase stay in the 60sC Line specially if the chip aren't delided. in delided chips as the heat are better transferred the CPU Tcase and Cores are more similar. but still not equal.

I've seen my 4770k drawing near 150W and just keep on chugging along. 84W is totally relative because these chips you can basically dial in how much wattage you want to draw from down around 10W to my obscene max under avx2 with hyperthreading on. I can't compare to the FX series but my educated guess/assertion is a 4770k at stock speed MAY run a LOT hotter than a stock 8350 depending on how you have the Intel chip configured. The Phenom II 1060t I had previous to switching for z87 was far easier to cool while running all of its instructions, but it couldn't get to the same degree of efficiency while just putzing around doing normal stuff.

One thing I'd point out is that there is a big problem with Haswell's Integrated Voltage Regulator. Just running Valley benchmark looped with a SLi setup my semi-HQ 4.6GHz 4770k will overvolt itself to 1.36V if not slapped around and suppressed using Manual voltage settings--as it will run fine at 1.265V 24/7 and that's a huge difference. These stupid chips go out of voltage spec on their own even at stock settings...You have to pretty much study the BIOS for a straight month to learn how to keep it from overvolting your chip while still taking advantage of low-power C-states. I have mine working as intended while overclocking the balls out of it still, but it's taken me way more time than I was expecting to get everything dialed in. I'm so sick of installing windows 8.1 by now that I'm ready for 9 already.

That said, I used an NH-D14 to validate my overclock with prime95 28.1 but I've since switched to a little bitty Corsair H55 with 2 Noctua NF-P12s in push pull (uses excellent newer mounting solution for z87 boards, imo, as compared to h80i which is horrible) and even at 4600MHz I can do everything I normally do without going above 65ishC max which is fairly normal and cool for a Haswell, especially at 46xCore 44xCache, and 2400MHz on the IMC. I can loop Valley for hours and that's as hot as it gets. Very happy with the Corsair H55 AIO. Never been a Corsair fan in the past, avoided their products generally, but now I have a K70 Vengeance keyboard I love and this damn H55 that exceeded my expectations by quite a bit so far.

Protip: buy Corsair AIOs direct from Corsair instead of Newegg if that's what you were going to do. This kit I ordered from Corsair came with a freakin' little BOW tied around it. Not like it was gift wrapped or anything just a plain ribbon bow. That's a pretty simple personal little detail but I felt confident enough to go ahead and install the kit after my first attempt at "watercooling" with an h80i I purchased from Newegg slowly made a little puddle of coolant on my workmat while I had it laying flat to see why it was running so hot. No harm, no foul but I was not going to ever order any more watercoolers from NE. If I had had any watercooling experience I would have known there was a problem when I unboxed the unit and heard what sounded like a "rain stick" effect coming from the radiator as I turned it this way and that. This H55 didn't make a peep while turning it.

What cooler are you running. At stock speeds that chip should not hit anywhere near 60c playing those games or any. Should be mid 40's or less. Ive owned 3 of the fx 8 cores and can only get mine to hit 60c is during the intel burn test and that's only when the chips were overclocked. Stock speeds would average around 50 give or take. I also have never ran the stock cooler and that could be why. I don't own an i7 but they are suppose to run cooler from what I hear but your 8350 should not be getting that hot.

I'm putting a Thermalright HR22 in it, so that should drop the temps.

I did a bit of thinking, and it looks like an Intel has a 15 to 20c advantage, because if they run 5 to 10c cooler, and can run up to 10c hotter maximum, that's a 20c difference. Seems significant.

Even if it didn't run cooler you would enjoy your CPU much more and get more frames.. No matter if you go i5 or i7!

seems not, thats a lot significant specially in the Power Consumption, the FX8350 draw way more power than haswell more power consumed = More heat produced.you will be fine, the HR-22 its a great cooler you will be fine.. if you want to get the most out of your chip then remember to delid it .. now overclock and post results =D

Intel processors run hotter but produce less heat.
