Hey all, I just realized that the new i7-9800X is costing just over the average price + tax of the i9-9900K. I've been planning a build for the Z390 Dark + i9-9900K, but I'm curious if performance wise a X299 Dark + i7-9800X makes more sense as the X299 Dark is going for pretty good prices these days, probably less than what the Z390 Dark will run. Not much info on the i7-9800X out there other than base specs, but I'm curious on the performance differences between it and the 9900k. Any thoughts?

Your performance difference between the two will mostly be related to the architecture of the platform. X299 vs Z390. 9900k will still perform better in games solely due to the higher core clock.
With that said, if I didn't get my 9900k for $430 I'd definitely go the X299 and 9800x route instead.

What would have made you go that route instead? I guess the question is, what will yield better performance overall. X299 platform + 9800x or Z390 + 9900k. X299 more pcie lanes, 9900k higher core clocks.
Only potential use case I'd have for more pcie lanes is 2 gpus at 16x pcie 3.0.

It depends on what you are going to do with your PC.
If only playing games, the i9-9900K will be faster (higher clock speed).
If you mainly play games, the X299\i7-9800x would only be better if you plan on running multiple video cards in SLI.

The more and more research I do... the more I'm seeing 9800x is the way to go if you're gaming. The reason I say this is due to the PCIE config, whereby if I really want blazing fast gaming then additional graphics cards aren't a concern ($$$).
The reason I say this is that x299 is the new kid on the block as far as chipsets go, so with that being said, plus the additional PCIE lanes.... I'd go with that.
As a matter of fact that's the route I'm thinking of going just for upgrade potential.

I'm definitely thinking about it. Any links on it's overclocking performance?
I guess the question is, is 16x/16x on the 9800X enough to trump the sheer higher clock speed of the 9900K

Not until you run multiple GPU's. I'm super tempted to sell this 9900k and pick up a X299 Dark + 9800X. I'm just sick of waiting to upgrade and my new mobo will be here tomorrow. I think I'm just gonna stick with Z390 + 9900K. I'd also want to know if the 9800x can reliably hit 5ghz all core boost like the 9900k. If I knew for sure that it could, I'd probably sit and wait. I wish all this stuff was released at once. Everything just keeps trickling in lol. Had to wait for the 9900k and was lucky enough to snag one. Now I'm waiting on the Z390 Dark. I could buy a X299 Dark but then I'd be waiting for who knows how long on the 9800x. IT. NEVER. ENDS.

Lol, I am with you there. My i9 9900k I have had on pre-order with Amazon will be here on Friday, so now I am just waiting on that Z390 Dark also. Last piece of the puzzle.

Don't forget that the Z399 is coming ~eventually~ to pair with these 'new' CPUs. I anticipate the Z399 DARK will be out just in time to commemorate the heat death of the universe.
Oh, and you'd have to double up on the RAM you've already bought, which has probably passed its return window, because to take full advantage of the X299 or Z399, they're quad-channel boards.

I can't find any 9800X benchmarks online, nothing. Woulda thought the typical blogs and reviewers would have received some samples by now. It will be a very interesting topic if the 9800X can get a little past 5.0ghz on all cores. You'd basically be sacrificing only .1 to .5 ghz (unless the 9900k goes way further with better cooling) for the full 44 pcie lanes and more dimm channels.

I'd imagine it'll perform ~10-15% better than the 7820X. The only difference between the CPUs are 11MB L3 vs. 16.5MB of L3 "SmartCache" and the 9xxx HEDT chips use the new sTIM, which is probably because they've got a 165W listed TDP on ARK. Intel still has them listed as "products formerly known as Skylake," so I'd imagine they're 14nm++ chips instead of the 14nm+++ Coffee Lake process. And we still haven't seen [fudge] all information about the Z399 boards, either.

I know some outlets passed on the basin falls refresh as there just isnt a huge stoy to be told. From the stuff on the 9980XE that is out there, it looks like the intel iteration of solder that plagued the 9900K with thermal headroom issues is present in the X299 refresh (see the Der8auer video on the 9900K). I had shuffled platforms around to get to a fresh build with the 9900K and I'm not doing it. I've actually sold off two of them that I had pre-ordered along with the ever elusive Maimus XI Formula motherboard. I'm rocking an Aorus Z390 Maser and an 8086k. I grabbed the X299 Dark and I'm now targeting a used 7900X that I can delid. It'll have less thermal issues then it's replacement and will likely get to 4.6 or 4.7 without anyhin exotic (I've had several 7900's in he past). If I can't get the CPU ithe Dark X299 will sit Idle until 7nm Zen drops and we ee if AMD can take advantage of Intel's issues. I really wish Intel hadn't screwed up so much in the recent past. But IMHO thy really have.

I'm just shocked that no one has made any in depth reviews of the 9800X as the price point is so close to the 9900k. And in the example of the current X299 Dark pricing, X299 Dark + 9800X is actually cheaper than Z390 Dark + 9900k with the assumption that Z390 Dark will be over $300. Sure you'll need to double up on Ram on X299, but at that point you're either in or out. I just posted this in another thread, but considering just performance... what is better. 2 x GPUs at 16x/16x but with slower clock speeds... OR 2 x GPUs at 8x/8x with higher clock speeds. That's the kicker, what is more important... 16x/16x or higher clock speeds. Note the lower clock speed tradeoff on the 9800X is unfortunately an assumption as we've seen NO benchmarks. Let's say it OC's across all cores to maybe 5.0ghz-5.3ghz, than I'd probably go that route as my goal with the 9900k is to OC to 5.5ghz across all cores. I'd sacrifice .2ghz for the extra pcie lanes.

The 9800X will almost certainly not clock as high as the 9900K. Intel has stopped producing the 10 core LCC die that 7800X, 7820X and 7900X all used to share. Now everything is on the 18 core HCC die. This is why the larger cache is present on the 9XXX series chips because they are all cut down 18 core parts. There is also the matter of the memory controller on both platforms where in the ring bus design on the 9900K is better suited for games with its lower latency. The only real benefit you’re potentially gaining is the extra PCI-E lanes that the refresh Skylake-X parts are now offering. This is only if you’re intending to run SLI however that it’s worth even mentioning. Even with that there is virtually no performance loss even on RTX cards in SLI between 16x16 or 8x8. The better gaming performance and clock speed advantage will be had on the 9900K platform. Edit: also shooting for 5.5Ghz as a daily driver is very unrealistic even for a 9900K.

Much appreciated on the above. Sounds like the 9900k on Z390 Dark is the way to go.

Yeah, not even Tech Jesus got 5.5Ghz on his 9900K with a custom loop running the biggest radiator I've ever seen. Hope for 5Ghz at a realistic VCore with good offsets, and in my case, I'm likely going to disable HT and make myself a "9750K." Of course, learning that the Z390 DARK is now coming in "December" is giving me pause as I'm now on the clock with regards to my just-delivered-today 9900K being on a less-than-30 day return clock.
Going with an X299, you also have to go with a 4x8 kit (going 4x4 on a HEDT setup should be illegal) since the X299's a quad-channel board.

Hehe yea definitely a little over ambitious with that hope. Would love to see some more temp data with different cooling setups when running at 5.0-5.2ghz. My build is going to be super overkill on radiators until I put a new GPU on water later this year or early next. Should be interesting to see how the CPU responds.

First of all it helps with frametiems. Not frame rate. Again educate yourself. There is better frametimes and less spikes. I have x299 and done the testing myself.

So now you’re saying Steve from Gamers Nexus is also wrong? Lol please kid don’t make me laugh try actually reading the article before ignorantly posting your nonsense in reply. As for your anecdotal experience I’ve run SLI and Crossfire on virtually every generation of cards since they were possible to do so. I’m not just speaking for the sake of speaking like you are. I’m speaking from years of experience. Now go sit down and read the article, watch the video and try actually learning something.
