7900X Coming In Hot?!

Recommended Posts

Posted · Original PosterOP
Quote

We managed to hit 4.5GHz with a Vcore of 1.275V. Then for the cooler we have the Kraken X62 CLC, fans maxed out, pump maxed out. So it's an adequate cooler for anything normal. The last couple Intel releases have not been normal in the thermal department as discovered with the 7700k... So temperatures we were seeing north of 90 Celsius with 4.5Ghz at 1.275V and we were still seeing pretty high thermals without the overclock as well. That will be covered in a separate piece from us... Quite hot 95C package temperate with cores high aswell which is going to be some what of a limiter in the future for overclocking. Lastly power increases by a couple hundred Watts when overclocking and that's especially true when you start OC'ing memory aswell. So this is a cpu that is definitely more power hungry than those we have worked with recently.

Well damn no wonder they have a whole separate video planned on thermals and power upcoming! These are just key notes and I look forward to seeing GN's dedicated video on the topic as these guys are super thorough and have excellent test methodology. 95 degrees at a voltage as low as 1.275V?! Damn! what's your thoughts on that guys? Unlucky to anyone who loses the silicon lottery and needs to push 1.3V or more for their OC. It's not the end of the world you can rectify it by delidding and doing the job Intel should have done in the 1st place, I guess the thing to take away from this for me personally is why did they have to cut corners with the enthusiast platform like lack of solder that they didn't cut before?? It's just a shame that a delid of modern Intel processor is almost compulsory, and while that might be ok for the 7700k I wouldn't be too comfortable doing this to a $1000 cpu, would you?!

 

Full video below, you only need to watch the 1st 5 mins though the rest is off topic. Note when you see ellipses above it is to keep the text quote down to essential wording only. Full version in the video of course.

 

 

Update 23/0617

 

Techspot review weighs in with more detail than the brief GN key notes

 

Power:

Quote

Up until now the new Syklake-X processors have looked mighty impressive. The 6-core 7800X sucks down the same 193 watts as the 8-core Ryzen 7 1800X -- I was hoping it would be closer to the 1600X. Still, the 7800X isn't really the issue, both the 8-core and 10-core models are considerably more power hungry.

Both pushed system consumption over 200 watts and that's significantly more power than what the 6950X system used. 226 watts is a huge amount of draw for the Excel test, let's move on and see what the power consumption figures for the Cinebench R15 test look like. Okay so these numbers are even worse, quite a bit worse. The reason for this being that the Cinebench R15 test is not just more intensive, but it also runs for quite a bit longer so the chips heat up more and consume even more power. For this test the 7900X was sucking down almost 260 watts whereas the 6850X hit just 212 watts. Clearly those higher clock speeds come at a real cost.

 

Thermals:

 

Quote

Using just 1.2 volts, which is all I needed for a stable 4.6GHz overclock on all cores, the system consumption went from the 259 watts just seen to an insane 402 watts! That might not even be the worst part, the deal breaker is probably the operating temps. Chilling the 7900X was Corsair's H100i v2 and despite being a premium 240mm AIO liquid cooler, temps skyrocketed as the CPU was place under load, reaching 90 degrees instantly before climbing further towards 100 degrees.

 

Additional:

 

Its very interesting when like Steve you don't receive a reviewer sample from Intel...

 

Quote

My chip only managed a stable 4.6GHz and no matter how much voltage I threw at it I wasn't able to stress test . The system would boot into Windows but would blue screen within the first few moments of running a stress test.

 

Spoiler

 

Note in the above image the immediate temperature spike when under load at just 1.2V and throttling. Also lets look closely here at the tests Steve ran. In Aida64 the "stress CPU" option means the AVX instruction set is not used. To my knowledge the "stress FPU" must be selected to utilise AVX instruction sets in aida64. So for everyone assuming the high temps are down to AVX, bad news fellas...

This is why it's not a good idea to set up a cadence that capitalises on the absence of competition. Intel's been beating a drum that only sounds good without AMD in the mix... and it's like watching a trainwreck in slow motion as they try to change gears. They can't stop it overnight, and they need to understand that.

it is so sad, the silicon looks good, but the whole TIM issues, X299 being a cluster fuck is a real turn off.

Butttttt testing with close loop piece of shit AIO's is a turn off.  Put a custom loop on it so we can see the behavior on a more standardized "best case" cooling setup and then people can extrapolate downwards if they use an AIO.

Wow, too late to hit the abort button? I haven't had a chance to watch the clip, but what did they mean by high stock temps? I'll have to watch after work.

 

I'm assuming Linus is working on another dramatic rain scene?

The rain is the only way to cool it so call it the review from Linus ;)

I, personally, think using one of the best off the shelf AIO's is a much better way of standardizing than using a custom loop.

 

Logic is weak here.

In the video he says stock temps weren't much lower he doesn't disclose numbers. You'll have to wait for the full video for that. This was probably just a heads up for people who preorder. Prevent a nasty shock ya know.

I know, I just knew that you would be the first to post it in tech news :P Gamers Nexus is an extremely credible source. :D

 

Anyways, 95C is unacceptable IMO (they could have soldered this CPU) and I think that the 12+ core CPUs definitely have to be soldered, because if they aren't they are going to hit TJmax at stock speeds xD

I am not buying one, so I could care less :P But I really hope that they don't just lower the clocks because having to delid a $2K processor would be just ridiculous.

 

If they decide not to solder them, they should just ship the CPUs delidded out of the box -_-

Actually I doubt it. My reasoning being if they have to solder the 12C and up then that is admitting that they could solder them they couldn't be bothered. If they don't solder any of them then they can remain silent in that grey area where some people will say "it's because they can't" even though it's a monolithic die like X99 in terms of size and that was soldered... Kaby lake mainstream ok they get a pass it is small.

That's actually a good idea. If they are going to skimp on quality then they should just not bother, it makes a delid far less risky if they ship with the IHS in a separate bag.

Yeah honestly they should have just soldered them. If there is a reason they didn't other than maximising profit then it better be a good reason.

Yeah, der8auer said in his video that Intel was using thermal paste from the get go. I guess that they didn't expect Ryzen to be that good xD I think that they may solder the 18 core because they weren't planning on releasing a 12+ core CPU, so they may try to make up for the lack of solder on the 6,8 and 10 core CPUs........

No, this is what they said: "If you don't want high temps, don't overclock because overclocking voids the warranty of your processor and increases CPU temperatures"
