Description

For the Intel X299 release, MSI sent us their new X299 Gaming Pro Carbon AC motherboard with custom cover plates as well as an Intel i7-7800X processor. To help keep the processor running cool, we used Fractal Design's recently released Celsius S36 CPU cooler.

You can watch our build video to see how it all came together and check below for our stock and overclocked benchmark results.

A big thanks to MSI for providing the motherboard, processor and video card as well as to Fractal Design for providing the CPU cooler used in this build.

And now, some benchmarks:

Stock Results

First off, we ran everything at stock clocks and settings except for enabling the Extreme Memory Profile (XMP). With the default CPU clock settings, the i7-7800X runs at 3.5GHz with a max turbo speed of 4 GHz. Under that setup, here's what we saw:

Overclock Results

We used the motherboard's "Game Boost" feature to overclock the CPU. It offers 7 settings beyond the stock level (labeled 1, 2, 4, 6, 8, 10 and 11) and we were able to get stable results on all but the highest level. With Game Boost set to "10", the i7-7800X operates at 4.6GHz. Here are our results with those settings:

That GPU sag doesn't look very good.....

[comment deleted by staff]
BoyScout staff submitter 18 Builds 4 points 1 month ago

So that's on me -- usually if I notice connecting the cable will cause a bend, we'll shoot it with Ryan using one hand to hold it steady from below (though it can be quite tricky to film that and not block what's actually happening). We filmed this video pretty fast and unfortunately I didn't notice the notable pressure there as well as with the 24-pin cable until editing, so we didn't get a better take.

That said, I don't think that has much to do with the sag. The card itself is pretty heavy thanks to it's pretty substantial block/cooler.

Hector1908 3 Builds 1 point 1 month ago

You can attach the cables before or after it will sag the same . The card is 320mm long , those cards are just heavy . . I always attach the cables after and sometime is sagging and sometime it doesn't . Depend on the mobo psi slots , weight of the card and all that ... Great build btw .

Wow, first comment? Man as much as im not a fan of core i9, that is a sexy computer! +1 to you for the pretty build, one for MSI for making such a good motherboard and graphics card designs and one for the hell of it.

DarkestAurora 3 points 1 month ago

That's still an i7 tho

videonery 5 points 1 month ago

this new line up is going to be obsolete in three months once coffee lake is out. this is just trying to grab peoples money before the actual competition comes out

Anyansayo 1 point 1 month ago

I'm not so sure about that. Was the i7 6950X junk when the 7700K came out? I'd assume that intel will create quad cores as a top of the line next gen option but I guess that you never really can fully predict the business strategy.

mad3on 1 point 1 month ago

Does he mean canon lake? Coffee lake is just another 14nm reboot. Canon lake is set to move the process to 10nm. That could potentially nullify a lot of existing cpu's, a lot more than coffee lake will, but seeing as the laptop versions of the canon lake chips are going to be the first out, it'll be a while.

Anyansayo 1 point 1 month ago

Is all that information on the next gen intel CPUs out now? I thought that it was all speculation at this point.

BoyScout staff submitter 18 Builds 1 point 1 month ago

Glad you liked it! Thanks for the feedback.

pierocks321 1 point 1 month ago

Hi I'm new to the whole building your own pc thing, but I definitely need an upgrade from what I currently have. This build is right in the price range I'm looking for, but pcpartpicker claims there may be some compatibility issues with the parts. Could you clarify? I'm looking to copy this build for high end gaming so I was wondering what monitor you would also recommend. Thanks.

BoyScout staff submitter 18 Builds 1 point 1 month ago

There are several compatibility notes, but they are just warnings. The main one of interest is the removal of the 3.5" HDD cage to use this particular GPU due to its length. If you plan to use a traditional HDD in your build, be sure to edit the part list and find a shorter option (there are plenty -- this just happens to be a particularly long card).

Boss602 1 point 1 month ago

Looks great.

I'm thinking of getting the gtx 1080 ti msi duke, how are you finding that card?

BoyScout staff submitter 18 Builds 2 points 1 month ago

As you can see from the benchmarks, it performed well during our testing. It's a sharp looking card, though be sure to note it's size. At 320mm it's a bit longer than most 1080 Ti's so you'll want to make sure the case you put it in has the clearance.

The positive of the extra length is the width is only 42mm, meaning it doesn't push past the two slots needed like some Ti's that require 3 slots of room. Also be aware that it's pretty heavy (as others have noted the slight sag). It's holding up fine in the week we've been testing on it, but I wouldn't argue with the suggestion of a support bracket.

NovaTastical 1 point 1 month ago

Can we have comparison gaming benchmarks? Like compared to other CPUs to see which ones the best on the X299 CPUs?

BoyScout staff submitter 18 Builds 1 point 1 month ago

Our results showed that the CPU was barely taxed for the gaming scenarios we threw at it. We were limited by the power/temperature targets we had set on the GPU.

So are you looking for a comparison to other X299 CPUs? Or compared to a similar Z270 builds?

NovaTastical 1 point 1 month ago

Both if possible

Boith 3 Builds 1 point 1 month ago

Nice to know my 5820K is barely behind the 7800X (granted, OC, but still)

EdInk 10 Builds 1 point 1 month ago

Like the custom VRM heatsink, nice touch.

It would be interesting to see how much power was drawn by the CPU, stock and OC'd

butcherpete16 1 point 1 month ago

It seems your CPU Temperature under Load at 89C is rather high. Can you comment on what you mean by "under load?" Some other sources I've read have suggested not to go regularly above 75C and I would like to hear your opinion on it.

Thank you

BoyScout staff submitter 18 Builds 1 point 1 month ago

That was the load temperature while running the maximum overclock we were able to keep stable. The non-overclocked load temp was only 55C (as noted in the build details side bar).

The "under load" temperature we report from manual benchmark testing of our video builds at the moment is usually the highest temperature reached while running the 3DMark suite of synthetic benches. However, if we see higher temps during game play bench testing, we note those as well.

Thanks for your feedback!

alexmorgan202 1 point 1 month ago

Nice build! I'm thinking about making a build with one of these processors, but I'm split between the 7740X and the 7800X. I know the 7740 has higher GHz, but less cores and I'm not sure which I should get if I am looking to game.

Here's what I have now: https://pcpartpicker.com/list/cPtJ9W

Thanks for your help!

BoyScout staff submitter 18 Builds 3 points 1 month ago

So the downside of switching to the 7740X is that it's only has 16 PCIe lanes versus the 7800X's 28 lanes. It also only supports two channels for DDR-4 memory instead of 4. For $40, it's a pretty massive feature downgrade from the 7800X, beyond the core count drop (quite a few motherboard features get disabled with a 16-lane CPU on these boards). If you're after CPU intensive operations, the 7800X can represent a pretty good deal.

That said, if you're really looking at a 7740X-level performance just for gaming (and don't have some other particular reason to buy in to the X299 platform), you might just want to consider a Z270 platform / i7-7700K-based system. You'll get essentially the same gaming performance and save a great deal on the budget.

darkshadoku 1 point 1 month ago

What about a 7800x or 7820x for pure gaming performance and possibly some streaming? and SLI if possible.

BoyScout staff submitter 18 Builds 1 point 1 month ago

So the 7800X definitely handled everything (at stock clocks) that we threw at it. The 7820X (with 2 more cores) would certainly do no worse.

It would have been interesting to try it with SLI 1080 Ti's. We may have to try that on a future build.

darkshadoku 1 point 1 month ago

So do you think this would a significantly better result in games as opposed to just getting the 7700k? The reason i am asking is i am currently on an old Phenom II X4 810 and I will be building a new Gaming PC in the next month (or month and a half) and i was looking at this extreme processor since i am building fresh

BoyScout staff submitter 18 Builds 1 point 1 month ago

We have another 7700K / 1080Ti build coming up later this week, but the closest equivalent build that we tested with a 7700K that I can quickly show you right now is an mini-ITX build we did last month for a LAN party. The 1080 Ti we used in that build wasn't clocked as high as the MSI DUKE in this build, but you can see it's relative performance to our build above.

The 7800X leaves the 7700K in it's dust on CPU-intensive benchmarks, but overall gaming performance is well within reach of each other because the GPU is playing such a critical limiting role. You can see a slight FPS boost here over that system, particularly with BF1 and Wildlands that take decent advantage of the extra CPU performance, but that's also the impact of the higher clocked MSI DUKE card.

Now look back at our recent 2-Way SLI GTX 1080 / i7-7700K build and see that while two 1080's can reasonably out perform the single 1080 Ti in this build, even though the CPU (/physics) scores are significantly behind what the 7800X can hit.

So on balance, no -- the 7700K isn't going to hold back your performance, at least not with current generation games and GPUs.

89c cpu... great job intel :/

BoyScout staff submitter 18 Builds 1 point 1 month ago

To be fair, that was under load with our 4.6GHz overclock across all cores. It ran at a cool 55C under load at stock clock speed. There's probably a happy medium to be found in there with more tweaking.

J_Vilander 1 point 1 month ago

so 4.6 is redline?

BoyScout staff submitter 18 Builds 1 point 1 month ago

If I recall, the temps we got at 4.7 (which is the max offered by the built in OC controls) were approaching 99C, and more importantly we started seeing a lot of crashes. I don't know that I'd want to sustain temps at 89C either, but at least the benchmarks and games we tested were running pretty stable at 4.6 GHz.

This was also just intended to show off what the motherboard's on-board easy overclock feature could do. You might be able to tweak the parameters to get faster stable results.

DeltaForceGM01 1 point 8 days ago

having any trouble with the 8+4 pin cpu power?

BoyScout staff submitter 18 Builds 1 point 7 days ago

We didn't have any issues. What kind of trouble do you mean?

DeltaForceGM01 1 point 7 days ago

i heard the cpu power cables where heating up and that the cpu may require a 8+8 for high OC

The SSD is running cool. Just realized I forgot to post it (will update), but we monitored its temps since we wanted to see how the thermal shield was doing.

Under load and with peak temps in the system, it was running at 42C. There's a lot of air moving from the front of the system across the board, which is what allows the thermal shields to be useful at moving heat off the drive.

So.... the reason there's no HDD in the build is that we ended up removing the only included HDD mounting options to install the cooler at the front of the case. Mounting the cooler at the top would have made it possible, but just didn't look as nice, both on the tube orientation and it blocked the view of the motherboard (which honestly, we wanted to show off).

But Phanteks does offer an optional HDD mount that would sit under the shroud. And, of course, you could use the other M.2 slot or 2.5" HDD/SSD drives for additional storage.
