    Hello,
    Does anyone here have the 9800x yet? I'm wondering which one would be better buy. I'd use it for gaming and video editing sometime. Thank you.

    Chatted with a guy who only got 4.6 out of his 9800x.

    From what I've read so far, the 9900k runs really hot. Did you happen to ask about the temps on 9800x?

    If you don’t need the PCIe lanes then the 9900k is a better buy.
    In other words, if you’re only using one video card and perhaps one nvme ssd, then the 9900k with generally higher clock speeds will be more beneficial.
    If you actually need a bunch of workstation features such as multi gpu, nvme raid, capture cards, raid cards, or multiple other cards that all take PCIe lanes, then get the 9800x.

    9800x costs more over all, as it’s not just processor cost. The mobos are all mostly over $250 on x299. Some as high as $500.

    9900k runs too hot though. I'll see if someone will let me know the 9800x temps.

    Define 'too hot'..? I mean who cares if it runs hot, it's the end result performance that matters. The 9900k will get higher clockspeeds, hotter or not. Harping over the temperature itself is pointless.

    I mean Skylake-X runs pretty hot, too, but again looking at that metric alone is not useful.

    Maybe you're right. It'd be good heater during the winter. I wait for good price on 9900k.

    Z370 or Z390 board and which brand?

    Z390. I tend to think less about "brand" and more about quality of a particular product. That isn't just for buying motherboards, that's general buying advice for literally any product (cameras, cars, computers, etc). Every brand makes exceptional parts. And basically they all make some duds (if not outright failures, then bad value for money).

    That said. this time around for Z390 generally Gigabyte is making the best products from a VRM standpoint. And that really matters for a power hungry and hot chip such as the 9900k. For more, you can watch this primer:

    EVGA Z370 Classified any good?

    If you're going to run Z370 with a 9900k, you'd better do your research to ensure that its power delivery is up to supplying it. That would take someone with experience with that board and a 9900k, or at least someone who understands the theoretical power delivery of a given board.
    It will be incredibly difficult to use Google and search for Z370 boards that adequately support the 9900k. They all will from an updated BIOS perspective, but not necessarily from a power delivery perspective.

    To cut directly to the point, I'm not sure why you're looking back rather than looking forward. It sounds like you want to make the search for compatibility more difficult rather than easier when there are tested solutions that are known to work.

    Because I could get z370 classified for about $120 :=]

    You want to buy a >$500 CPU and pair it to a motherboard on the basis that it's cheap? If cost is an issue, then perhaps you should go with the Z370 and buy an 8700k instead. Then you'll at least guarantee no issues and you'll have your lower cost board. And also save another $200 on top of it.

    That's why I said I wait for the 9900k price to go down, not paying $500+ for it.

    The only way it's going to go down in any meaningful way is by waiting for next gen Intel processors to come out. Which will be Sunny Cove in the second half of 2019. But then it's likely that you'll want that (because it'll be the top end processor with significantly upgraded compute). The reason for this is simple. Intel is incredibly strained on its 14nm output. I don't foresee in remotely the near future that Intel will be able to meet demand on 14nm. Heck, they're so behind that the 9800x hasn't even hit the channel yet.

    You're always going to be in this waiting situation if you want the top end. Right now the 9900k looks juicy to you, but as soon as Sunny Cove drops you'll want that instead, and also want it to drop in price. If that wasn't the issue, you'd do what I suggested and simply buy the 8700k which likely meets all of your needs. As far as I can tell from your multiple threads in this sub-forum, you just want a gaming CPU and you edit sometimes in Adobe Programs. Both of those things don't need threads. Adobe apps aren't optimized to use lots of threads and prefer clock speed. Which is much the same in gaming. For your applications there won't really be a meaningful difference between the 9900k and the 8700k so long as the clock speeds are equal.

    You're always going to have this problem (wanting the top end but last gen being more cost effective for you). But what is more frustrating is that we're going through this thread and you're asking a bunch of questions, about theoretically what to buy when you're not even close to being ready.

    Yeah Sunny Cove is the reason. It will have hardware security fixes, I think.

    I wasn't going to sell my current chip and try to find a 5.0ghz 9900k.

    Then the Ebay coupon came up. $476 shipped for a 9900k.

    Keep an eye out, there are deals to be had.

    What's the max voltage on 9900k if you leave everything on auto/stock settings on the motherboard?

    Whatever the mobo manufacturer has decided it needs to be. I know that answer isn't probably what you wanted to hear but that's really the best one I can give.

    I'd like to know what's the max voltage on 9900k when it's on turbo 4.7ghz with stock settings. If that's possible. Thank you.

    What kind of use are you giving those CPUs? Anything I'm missing to justify the price? Or just overclocker enthusiast? I can't see myself buying one of those, insted I would just go for the 9900k or the Threadripper depending on task, or by the sake of overclocking just bin it myself.

    If you want guarantee at certain speed, you buy it. The 9900k 4.8ghz is $529 which cheaper than some retailers. I'd get it for the delid option... CPU runs cooler.

    Thanks for this thread! i was heavily looking at a 9800x, just to upgrade from a 2600k. Not that my old rig is the problem. I just want to upgrade (cpu/mobo/ram/nvme storage).
    Looks like ill be building a 9900k rig now. Now I just need $$$. LOL

    Ya I am going the same route. The only advantage really is the PCIE lanes. And even if you wanted to SLI 2080tis you would probably still see better performance on a 9900k with both cards running on PCIE 8x.

    Yea I'm a 1 gpu/micro atx only type. Don't want a big rig and just wanna keep it simple

    Unless you need quad channel memory and more PCI-E lanes, 9900k is a faster chip in every way.

    That is true. I get over 100 on reads/writes on aida on my x299 rig. But you gotta get some high end memory.

    Solid numbers. Took some tweaking for me to get latency to 55 range as well. Your read speeds are nutty. I think something was up with the write test though, judging by your timings/speed you should pull 100ish. Maybe a background app got in the way or something.

    The delid option is an extra $50, so take that into account. Also know that most people I've seen are getting 4.9 GHz all core overclock by themselves, but if it's cheaper to buy from Silicon Lottery then I can't argue with that. Note on the product page that it says 100% of chips they have tested have been able to hit 4.8 GHz, which is why it's not more expensive than current retail pricing. They state that 85% of all 9900K processors they've tested have been able to hit 4.9 GHz.
