Benchmarks & Conclusion
Benchmark Results
When coupled with the Core i9-7900X, the new motherboards outperform the old X99 platform across 3DMark and PCMark just slightly. Although it's far less expensive, the Core i7-7800X can’t stand up to the prowess of a 10-core CPU in 3DMark’s Physics test.
Our hopes that the moderately-priced i7-7800X would compete directly against the previous generation’s expensive 10-core CPU are extinguished in Sandra Arithmetic. However, the Core i9-7900X beats its predecessor by an even greater amount. Better still, the boards hosting these new processors are performing consistently so far.
Minor inconsistencies between Asus and MSI motherboards creep in starting with Sandra Multimedia. MSI appears to have slightly more aggressive memory settings, but Asus leads Cinebench.
3D Games
The Asus Prime X299-Deluxe is bested by MSI's X299 Gaming Pro Carbon AC across Ashes, F1 2015, and Metro. We always enable each CPU's full set of power savings features and disable non-stock turbo settings to make competitions fair, as we believe that overclockers prefer to choose their own settings. Perhaps some of Intel’s green technologies aren’t fully functioning on the MSI motherboard?
Talos rewards the Asus board, and punishes MSI, taking it down a notch due to the heavy load of its Nahimic software suite in this specific game. The faded bars show how the X299 Gaming Pro Carbon AC performs with Nahimic Audio Solution disabled.
Timed Applications
Less is more in timed application performance. Less encoding time means you get more work done.
The Asus Prime X299-Deluxe falls to MSI's Gaming Pro Carbon across our mixed workload, but climbs back in the lead in Adobe After Effects.
Power, Heat & Efficiency
We had suspicions about MSI’s potential power use after seeing it succeed too often in our benchmarks to call those wins coincidental, and the power chart confirms those suspicions. Full-load heat is also significantly higher.
Considering the balance, the X299 Gaming Pro Carbon AC’s relatively consistent lead wasn’t large, unlike its increased power consumption. A retest may be required before comparing it to any future competitors.
Overclocking
While the Prime X299-Deluxe beats the X299 Gaming Pro Carbon AC overclocking either processor, the reason for stopping is different. While the Prime X299-Deluxe experienced the traditional system crash when taking our Core i9-7900X from 4.3 to 4.4 GHz at 1.20V, that same CPU would throttle down its eighth core when pushed past 4.20 GHz on the X299 Gaming Pro Carbon AC.
Surprisingly, the Prime X299-Deluxe switches positions in memory bandwidth against the X299 Gaming Pro Carbon AC, depending on which CPU is installed. We’ll likely find more consistency as these boards mature.
The Prime X299-Deluxe costs more and provide more features, and disregarding those features results in less performance per dollar. Perhaps I should have used a cheaper X99 motherboard as the baseline, just to knock the X299 Gaming Pro Carbon AC down a value peg?
Since we included several processors in these benchmarks, a processor-based adjustment reveals a little more about why a buyer who had not yet made the leap to a 6950X might be glad he or she waited for the 7900X. Value increases by nearly half when moving from the 6950X to 7900X, and by half again when scaling down from the somewhat-expensive 7900X to the mid-priced 7800X.
The value charts tell us less about the boards, since the difference in included features is vast. Including its second network controller, Thunderbolt 3 add-in card with DisplayPort cable, the additional components that make its Wi-Fi controller an 802.11ad solution, the OLED verbose status display, and even the extra fan module should add at least $100 to the price. It costs around $120 more than the X299 Gaming Pro Carbon AC, so it should be close to par in value.
Unfortunately, both boards are slightly too immature to issue an award today. The Prime X299-Deluxe is closer to where we’d like to see an awarded motherboard be at launch, and for that it gets “the nod” in lieu of any award. And maybe a wink as well.

Can you imagine trying to fit one of these CPUs into a 2U chassis? It would be a nightmare.
Now that whole Kaby Lake X nonsense makes even less sense, right?
Anyway, I passed on this... We need a way for M.2, U.2 and PCI-E to NOT share SATA ports, same for any new tech... should find something else to make useless...
It's not that it's overkill. It's actually not overkill at all. It's just very expensive, an epic pain to cool, and offers a dizzying array of incompatibilities and caveats for the price.
Save your money for ThreadRipper, or stick to Broadwell-E. Skylake-X isn't worth the effort, confusion, noise, or cost that comes with the 2066 socket. If you really need the performance, grab a dual socket E5 setup before considering the X299 platform. It's easier to cool, makes system design simpler, and you'll end up with a quieter machine.
Yeah man I appreciate the advice and understand. Spent too many hours looking into all my options. To be frank, I don't think AMD will release an 8 core TR chip that's faster than the Ryzen 1700/1800 so as not to cannibalize their own product and the 7820x is performing 10-15% above the Ryzen chips for games. Money is not a factor for the most part, If I was interested in a single one of the other X299 chips I'd at least wait for TR4/Coffeelake, but the 7820x has no direct competitor, outside of Ryzen, and I don't think it will for a while. As for cooling, running custom water with a fairly beefy setup, not crazy worried about noise/heat (although I'm really unimpressed with how Intel has handled the heat..). OC3d is showing a 7820X running at 4.8Ghz at 1.22V with roughly 70 degrees under load. Even if he won the silicon lottery, I'd be fine with 4.5GHz at a similar voltage/temerpature. My 3570k runs at 4.6 at 1.2V and hits 65 under custom.
As for purchasing it, I will definitely wait for more reviews and maturation before I do. To add, the anti-consumer things intel does, albeit a dick move, don't affect me. I don't RAID, I'll never SLI, I'm only going to be running 1 NVMe drive. This truly is just an overkill gaming rig and I won't 'upgrade' my 3570k to another 4 core option, so 8 it is.
One last note: I am not trying to defend Intel at all and quite frankly, I want to give my money to team red, but I'm in a very specific boat and thus, not a lot of option left imo. I unfortunately/fortunately game at 144Hz and that 10% difference actually makes a difference lol, it's a vicious world. My 3570k is starting to hold my 1080ti in some games, so I've had to upgrade for a bit now.
