There is no 7920XE model, you really mean the 7980XE.

We can try to get an estimate.

i9-7900X does from 4377MHz (air) to 5671MHz (LN2) both average values. The current record is 6106MHz.

Considering the higher TDP and the higher core count, the average overclock on air would be approx.

4377MHz * sqrt[ (165W / 140W) * (10 core / 18 core) ] = 3542MHz

Alternatively, we can take the ratio between base clocks and assume it will remain constant when overclocking. This gives

4377MHz * 2.6GHz / 3.3GHz = 3449MHz

Both values suggest average overclock of about 3.4--3.5GHz on air. I would expect 4.4--4.5GHz on LN2.
 


Yeah sorry i meant 7980XE (haven't memorized the new CPUs yet).

Yeah that's what i thought, but huh 3.5ghz on air that's it? Makes sense though 18 cores is a lot. I was hoping for at least 4ghz on air. No wonder per core overclocking is a big feature of x299.
 
Review of the 7820X

http://www.tweaktown.com/reviews/8299/intel-core-i7-7820x-series-skylake-8c-16t-cpu-review/index.html

Some interesting graphs in there for the youtubers that say x299 isn't good for gaming. This review used an improved BIOS, but it still doesn't reflect the platform's full potential:

I wasn't surprised to find that the new BIOS ushered in slightly lower power consumption, but rumors have it that a new beta microcode will reduce those numbers even further.

OC i9-7900X vs OC TR 1950X

Average performance on applications

Average performance on games

Well that makes it pretty clear TR isn't SOLELY for games... if it wasn't already blatantly obvious.
If you want a work machine and play some games on the side, the 7900x has more going for it - just between these two processors, I mean.
Both platforms only just came out though, so this can change.
 
Took this from another forum discussing sales:

Good sales for the SKL-X line despite all the biased reviews, bad press from suspect sites, and ridiculous rants like this one

https://www.amazon.com/gp/product/B0745486S1/ref=s9_acsd_simh_hd_bw_bxcb_c_x_2_w?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=merchandised-search-11&pf_rd_r=52F601VWB4WCG4A9G553&pf_rd_t=101&pf_rd_p=1381e980-855e-537b-94df-b4f4d642d410&pf_rd_i=229189&tag=hardfocom-20
 


Oh, good sales... 5th place and 8th place (this one behind a FX-8350 no less).

Plus, this can't be right. We all know the USA is absolutely biased to Intel (any picture will show you "USA" somewhere!), so this data you're providing is obviously incorrect and does not reflect AMD's positioning at all. All 10 spots should be filled with Intel extreme CPUs because the only reviews that matter are the ones that say good things about the 7900X and 7820X. That garbage R5-1600 taking first spot is an absolute mistake and that R7-1700X being 2 positions ahead of the 7820X is an obvious indication of incorrect data.

...Sigh...

Cheers!
 


ROTFLMAO it's SOoooo TRUE! Thanks for that funny Yuka!
 

The amazon page you link has retail price of the 7900X as $1,499,99!!!!!!!

That is obviously a typo. The price is $999, as you can check in the first page of this thread. In reviews of the i9 or in Intel ark page for the i9 model.

AMD Threadripper 1950X review: Better than Intel in almost every way
Cheaper, faster, and more feature-rich than Skylake-X—what's not to love?
MARK WALTON (UK) - 8/10/2017, 9:10 AM
If Ryzen was a polite, if firm way of telling the world that AMD is back in the processor game, then Threadripper is a foul-mouthed, middle-finger-waving, kick-in-the-crotch "screw you" aimed squarely at the usurious heart of Intel.It's an olive branch to a part of the PC market stung by years of inflated prices, sluggish performance gains, and the feeling that, if you're not interested in low-power laptops, Intel isn't interested in you.

Click here for Amazon Link to the Discounted 7900K for only $962.99!!!

Intel’s Virtual RAID On CPU supports up to 20 drives in RAID 0 for free, but if you want more RAID 1 or other redundant setups, you need to buy this key from Intel. RAID 5 and 10 will require dongles to unlock. Good luck finding them! Price guess ranged from $100-$299. So if you want these feature you can tac on another $399 to that sticker price! So, $1,361.99 for a fully functional 7900K!

Also, upon close inspection there is 1 review listed on amazon for the link you provide! Now isn't that something! I think you might want to actually read some of the things you post! It got 2 whole stars!

The Hardware Unboxed review is incomplete and biased. They essentially tested rendering and rendering and rendering and rendering... and games. And even in rendering they only selected benchmarks where the i9 isn't faster. Another source of bias follows from the comparison of an overclocked AMD chip vs an i9 on stock settings. However, they don't mention this fact in graphs giving the impression this is stock vs stock.

Who knows how many more issues are hidden in their review? One has to recall those are the same guys that tested an engineering sample of the i7-7800X instead an retails chip, and are the same guys that used an mobo incompatible with the chip and damaged the sample.

The launch price of the 7900X is $999. The pricing of $962.99 that you mention is only a 4% discount!

|962.99 - 999| / 999 = 0.0360
 


That is not a review. That is a rant as I mentioned here

http://www.tomshardware.co.uk/forum/id-3455797/intel-x299-kaby-lake-skylake-megathread-faq-resources/page-2.html#20144438
 

Don't forget to add the hidden cost! That launch price for a fully functional 7900X was $999 PLUS $399! $1,399!

Edit: Awesome Hardware talks about it at 11:10 yesterday saying rumors are $500 for the NVME dongle. But it's still currently unavailable, and no one knows exactly what Intel is going to do about it. Click here for link

And fortunately, Core i7-7820X doesn't suffer nearly as much as Kaby Lake-X. However, you do have to tolerate a "mere" 28 lanes of PCIe 3.0. Last generation, Core i7-6850K in roughly the same price range gave you 40 lanes, so we consider the drop to 28 a regression.

Click here for link to the article.
By limiting PCI-E lanes to 28 Intel effectively raised the entry level price tag to enter the HEDT platform for professionals like content creators who need those extra PCI-E lanes! Now Intel forces them to pay as much as double the price they paid with Broadwell-E to just get 44 PCI-E lanes!
 


4.8GHz on all cores on water!!!!!! :ouch: :ouch: :ouch: :ouch: :ouch:

https://www.tweaktown.com/news/58970/core-i9-7980xe-overclocked-4-8ghz-18c-36t/index.html
 


Where the "XE" models based on a second manufacturing node or just higher binned parts? Also, do they use toothpaste in it? Given the OC, I would imagine they're back to metal?

Also, this is weird. The official page of the CPU says "max turbo 3.0 -> 4.4Ghz", but says "turbo version -> 2.0" and "max turbo -> 4.2Ghz", all under a TDP of 165W. They needed 1.25v allegedly to hit 4.8Ghz on all cores, but I can't find the base voltage to get an idea of how the consumption would jump under that OC number.

That thing won't be a slouch, but I wonder why Intel is bringing it to the market... No, I'm kidding. I know why, lol.

Cheers!
 


You know Intel can't stand ThreadRipper is wearing the crown! They want to take that back as fast as they can! Btw have you noticed how fast Intel is slinging out processors now ROTFLMAO!
 


All X-models use the same process node. This is in the first page of this thread.

I don't know if the top X models are higher binned (as Threadripper dies) or if this was a golden sample, but the die size has to play an important role.

Intel no longer uses metal, it is an inferior technology.
 


That is not the price it is being sold for...while demand is low, supply is even less...
 


Just FYI, Threadripper now has native NVME raid capability for 0,1,10 configurations.
 
SA has published a fairly good review of the i9-7900X

https://semiaccurate.com/2017/08/24/intels-core-i9-7900x-review/

There are some mistakes like when he mentions turbo works only in one core, but overall it is a good review. Also it seems evident that the new BIOS is playing its role on power consumption. He also has good words for the X299 platform:

X299 is Extremely Flexible

With all of that out of that out of the way I want take a moment to clearly state that the X299 platform is awesome. I have yet to throw something at it that it can’t handle. I’ve used it as test bed for CPU reviews, our recent RX Vega testing, and now I have it running 24/7 as part of mining rig. With mainstream platforms like AMD’s Ryzen 7 offerings or Intel’s X270, I’ve found myself running out of PCI-E lanes when building systems with multiple graphics cards, NVMe SSDs, and PCI-E WiFi cards. With X299 that’s just not an issue because of how flexible and extendable this platform is. Credit where credit is due, you can make this same comment about AMD’s competing X399 HEDT platform as well.

Resume: the i9 wins in ST, gaming¹, power consumption, and efficiency, whereas the 16C Threadripper wins in MT, but by a small amount.

¹ Yes, I know that a better gaming sub-testing would bring a much higher advantage for the i9, but still they report a win for the i9.
