The overclock on both reviews is 4.7GHz under CLC, but the temperature is high. Most will probably want to drop 100MHz. Doesn't look bad to me ;)
 
 
Edit: Added 4.8 GHz in 10 seconds video.

    And it does look bad to me - this CPU with lower voltage has much higher temp than 6950x on higher voltage.
     
    Why? Because 7900X has toothpaste under IHS and 6950X is soldered. Requires some nerve to delid 1k+ USD. Not to mention the fact that they applied thermal grease simply to keep costs down for CPUs with so expensive price tag. Ryzen costs around 300 bucks and is soldered..
     
    Would love to own HEDT but for me it is really difficult to ignore rather goofy approaches by Intel, seems that Z370 or whatever the chip will be is the way to go.

    I skimmed through. What exactly were the temps?
     
    Can't watch video at work, etc...

    From bit-tech review:
     

    However, temperatures were definitely a concern with Cinebench and Terragen pushing 100°C with our 240mm AIO liquid cooler. As a result, while stable and potentially tameable under custom water-cooling, we decided to go for 4.6GHz for benchmarking, which required a super-low 1.22V. Interestingly our Core i7-6950X ran much cooler despite using a significantly higher voltage, albeit at 4.4GHz. This could well be due to thermal paste having been used between the heatspreader and CPU core with the new Skylake-X CPUs, in which case delidding could potentially yield significant benefits given the high heat density.

    It's nice difference compare to i7-6950X.
    This is best investment for 2017 for gamers with deeper pocket.
    People with i7-7820X lose nothing for games, frequency is similar.

    Im not sure I would agree with that, x299 looks to be a very weird platform for no good reason. Especially when threadripper will be giving you more pci-e lanes for less money.

    I think about performance. PCI-E lanes are not so important for everyone because again Intel have total more Gen 3 PCI-E lanes.
    44 + 24 vs 60 + 4. For people is important to keep SLI on x16 and enough Gen 3 lanes for installation M.2 SSD, PCI-E SSD and maybe Intel Optane Memory.
    I hope Intel Optane will work on X299. 32GB cost 80$.
     
    Other things worry me, because some memory bandwidth results are not so good as i7-6950X.
    I must check more memory write, read, copy results on
    i7-6900K/i7-6950X and i7-7820X/i9-7900X.
    i7-6950X is great investment for people who have X99 platform, because his price drop seriously and maybe could be bought from people who upgrade.
    I would not complain to find i7-6950X for reasonable price. Flux solder, 10 cores, work on 4.2GHz motherboard and memory ready for him, don't need 400-450 euro investment in that direction. I would scream like idiot from happines if I success to push him on 4.3GHz as i9-7900X Turbo Boost 2.0.
    Because they OC lower than Haswell-X.
     
    I don't know why platform look weird, Intel try to offer Kaby Lake-X and Skylake-X as soon as possible to prepare completely new stuff.
    This launch now X299 was finished before Ryzen 7 arrived and they couldn't do nothing except to increase Turbo Boost instead to offer manual OC.
     
    Worse of everything in X299, worse dissapointment for me is thermal paste and delidding.

    People need to open their eyes to how bad this launch actually is. Manufacturers of motherboards have to fab boards that support 4 to 18 cores and the 18 core is months away. These motherboards now require keys again as well and as far as I understand don't have native 3.1 USB support. Now they had to force a 20 degree cooler to keep those temps in line and were talking some of the best water cooling money can buy period. Even stock clock cannot be ran on air and the INSANE amount of wattage this cpu is eating basically sums up how badly this thing was rushed. I don't understand why intel panicked so hard. They should be in the lab developing cpus worth our money.

    Level 3 cache is much lower also @ 13.75 mb it's a rushed response by Intel is what it is. I love intel but if AMD starts to dominate again I would gladly go that route.

    Huf, you double posted so I removed one.

    Also, L3 cache is lower while L2 is expanded to all cores rather than being split per core, which some reviewers have already shown that it allows the processors to utilize L2 faster.

    Basically, it didn't matter.

    For those complaining about price... really.. 6950x was $1700... 10 core 20 thread, that was $700 more than the exact same thing you can get on x299. Yes, the TIM choice is bad..

    The x299 adopting the 7740k is strange, but like many reviewers have shown, it is the exact same price as the 7700k, meaning the chip and motherboard will be the first change, but if someone decided to grab a 10 or 18 core next year, they dont have to rebuy another motherboard, which is kind of nice.

    I personally don't care. My 5960x works perfect for everything. Those on x99 upgrading to show off they have the money to spend, let them. If you don't agree with Intel's choice, don't buy their stuff.. force them to make a change. Fact is, the x299 is going to sell just fine like Intel's stuff has. People that care don't matter to Intel, it's those with money to drop that Intel caters to.

    The reviews of the Kabylake-X parts show very odd thermals, I cant imagine the thermals of the 18 core parts
     
     
    Shown at 9:10

     
    5.3ghz delided is 16 degrees cooler then a 5.0 ghz with TIM? Thats just mind blowing awful.

    I'm seeing pre-sales orders for the new Intel chips for end of month delivery; think its best to wait and see more reviews

    Yup. It seems Threadripper will release in August and currently the X299 platform is not 100% stable because it's new, etc ... so waiting 1 more month seems like a good idea to me.

    AMD doesn't need to dominate to be a desirable product, they just need to be competitive. Which they are. My next build will undoubtedly be Ryzen. Matter of fact, I was planning on a 1700X but further investigating identifies the 1700 to be an excellent choice for my needs. I'm just waiting for Vega to drop, have all the wrinkles ironed out because lets face it, there will be some teething problems, and I will have my all AMD build.
     
    What I'm also looking for is good performance at the lowest possible TDP. The 1700 offers that, and I hope Vega has the same quality, at least when compared to Nvidia.
     
    At first I didn't want to believe it but now I have to agree with others. Skylake-X is looking more and more rushed, and complicated.

    AMD caused this and Intel is flailing around in water like lost pups. Its just making it easier for people to choose AMD with their next build. Its where I am headed. Thank goodness AMD has come through on the cpu front. We now have a good alternative. We no longer have to settle for Intel's shenanigans and only hurting themselves. Will the market react accordingly? Or will Intel continue to dominate keeping their dedicated customers simply because of brand name and recognition. Only time will tell.

    Now that I am seeing news on both fronts...AMD Threadripper is becoming more attractive.  Intel's prices are still out there.  Will wait for comparisons before making my move...but AMD has my attention!
