Intel Core i9-7980XE Hits 845W at 4.9GHz

[HKZeroFive]

Intel might have finally a created a valid reason to buy a 1000+W power supply with the introduction of their flagship X299 processor, the eighteen-core i9-7980XE. It's been no secret that the entire Skylake-X lineup has gained the rather unsavoury reputation of being power-hungry once you start to overclock but this takes the cake.

 

In LegitReview's test run of the i9-7980XE, they managed to get the chip at 4.9GHz after failing to achieve 5GHz. While the chip demonstrated an extraordinary score in Cinebench R15, it also displayed extraordinary power consumption figures at the same time, hitting an absurd 845W during the run. However, with the Corsair H105, the chip managed to stay at a rather cool 63C during benchmarking. Impressive.

When it comes to overclocking the Intel Core i9-7980XE we were delighted to find that the ASUS X299 Deluxe motherboard made that task easy. We managed to get into Windows 10 at 5.0GHz with just one change in the UEFI. All we did was set the UEFI to sync all cores and set the multiplier to 50x! The board automatically changed the core voltage from 1.35V to 1.40V by doing this.

 

Sadly, we couldn’t get 5GHz on a closed loop liquid cooler 100 percent stable, so we backed it down to 4.9GHz and started running some benchmarks.

The other thing we noticed with overclocking is that the power consumption was ridiculous. We went from 92 Watts and idle and 268 Watts while running Cinebench in stock form to idling at 169 Watts and hitting 845 Watts in Cinebench! The Intel Core i9-7980XE is rated at 165 Watts, but you can clearly see that overclocking takes it well beyond this. AIDA64 showed CPU temps to be reaching 63C during out benchmarking, which was also up significantly from the 41C we noted at stock clocks.

 

 

I think I'll give Intel credit where it's due. For a eighteen-core chip, managing to hit 4.9GHz stable is no small feat. The power consumption is obviously a bit excessive but I guess that's the trade off. Keep in mind that this wasn't achieved with LN2 or any of that stuff that hardcore/competitive overclockers use... just a 240mm closed water loop. Thought this was something worth sharing.

According to der8auer:

1000w @ 1.45v

 

He used 1.55v for 6.1ghz btw.

Ah finally, I've always wanted a $2000 space heater. 

 

Move over AMD, Intel is coming for your space heater title.

A bit excessive? Going from 260w to 400w would be excessive , not 500-800w for cpu alone.

 

udos for not burning up but talk about cooler and psu killers ...

[SeraphicWings]

I think I heard that PSU crying blood somewhere

[rn8686]

And I thought Vega was bad....

Not to mention a motherboard has to handle the crazy amount of power going to the chip.

845W with a H105 is really unlikely.

Also, how the hell did they keep the VRM cool? It probably kicked out 100W of heat on its own, unless you have basically jets blowing at the VRM coolers the things would overheat and throttle...

 

edit: also based on these results: https://www.gamersnexus.net/hwreviews/3066-intel-i9-7980xe-7960x-thermals-power-review

It's complete BS and the H105 is similar to a 360mm AIO and they are capable of cooling cpu's with up to a 500W power draw, anything higher would cause the liquid temp to go out of spec (above 60°C) and basically ruin the cooler really quickly.

I just wanna know if we're gonna have this problem again

With these kinds of overclocks, likely. The VRM's itself are likely capable of handling a decent OC but it's cooling them that's mainly the issue.

oh I don't gvie a shit about cooling it, I'll strap a honda civic radiator to the fucker if I have to, and for PSUs I'd love an excuse to see multi-psu systems again. I just want the motherboard to be able to handle it. 

Extreme cooling is a lot of fun, and I'd love to see a resurgence of it as a necessity if you want to make a top end enthusiast build.

there have been valid reasons to get 1kw PSUs for ages m8...

I want this trend to continue. I want see more multi psu builds again. I want to need multiple PSUs. I want to have to start lecturing people about the home's electrical situation and how to not start a fire. I want to help people shop for window air conditioners when their home has central air because their PC is heats their room too much for the central air to keep up with it.

there are 2WK PSUs, i cant say you would need more then that for any single CPU + dual GPU setup which is what we are moveing towards

Other than for those mining, most rigs don't require 1000W+ power supplies...

that dosent mean there are those that dont, get a 295x2, or dualm Furys or dual 980TIs with the highest cc I7 from the time and you will start to get there. 90% of consumer builds dont, but the enthusiast systmes can get there easely

None of those systems will require a 1000W power supply. Look up power consumption benchmarks.

heard of overclocking before?

It still doesn't consume 1000W of power. Show me benchmarks that say otherwise.

We are moving towards generic multi gpu not sli xfire. FOr a while, I expect that 3 and 4 way will contiue to die, but eventually come back, dependent on how well games support multi gpu in like dx12 and stuff. I would LOVE crazy 4 gpu setups to actually have gains, even if not near perfect scaling. Hell, it's possible, not saying it will happen, but since AMD is doing mGPU or whatever and NVIDIA is no longer pushing SLI as much, that when games start supporting multi gpu outside of xfire and sli we could see more than 4. Imagine that, people trying to make crazy case solutions and crazy PSU setups because they have money to waste. I might browse build logs again if that were the case. 

It'd be like mining but not budget oriented and slapping 8 gpus in a milk crate with zip ties or something.

Imagine it- 6 or more gpus, some of them mixed, enough radiators to cool an electric stove top, all for 10 extra fps in Assassins Creed: Dead Horse.  

 

Idk I fantasize.

one 295x2 uses over 500 watts alone, with a normal overclock on an 8350, a 295x2 without overclocking, you're looking at like 850 watt territory right there not adding in other components. That's a margin of 150 watts for everything in the system but the GPU and CPU in a world where they don't need a 1kw psu. 

I've seen plenty of builds with 2 of those for quad crossfire because stupid is as budget allows, that's over 1000 watts right there with no oc, and then you got the CPU. I'm pretty sure I"ve seen a few overclocked 8350 and dual 295x2 or quad 290xs in amd fanboy builds. Any quad gpu build for that matter. 

 

so, with respect, you're wrong.

240W for one CPU

275W for a 980TI limited by NVIDIA driver, 250W board power + maxed power limit

take two of them and you have a nice 790W

now add 150W for your systems drives and a waterloop and you get a nice 940W figure, 1KW PSU is a nice margin

 

*edit*

oh and a Vega 64 can pull 500W alone easy, two of them = 1000W alone

We are. There was talk of potentially X299 v2 boards, but the motherboard manufactures just put out beefier boards for the top-SKU chips. (The VRM spec was just too low, I think, in the first pass. Work fine for a 4c/8t though.)

 

Other thing is the Power envelope at Stock is roughly the same. That's why we're seeing upwards of 30-40% increase for 80% more cores in some tests, compared to the 7900X. And why the 16c can perform better than the 18c in certain circumstances. 

 

If you delid these, they'll do 5 Ghz without too much issue. They're Skylake cores on a 14nm+ process, they'll do it. It's just a question if you want to burn that much power.

I'll concede if he said two R9 295X2s, which amounts to four GPUs. The discussion was about one. Meaning that you can run it on a good 650W unit if you ever needed to.

 

Besides, I'm not talking about the crazy people who have four R9 290Xs in their PC. That's a different discussion altogether.

Hard drives and a custom loop isn't going to require 150W of power. You'd be fine with running that system on a 850W unit... they're not going to be running torture tests 24/7.
