The benchmarks come from Coolenjoy, where we learn that the CPU was tested on ASUS APEX motherboard (designed for overclockers). What was discovered is that the CPU boosts up to 4.2 GHz on all cores during Cinebench. It's unclear if this is a motherboard-specific feature or this is exactly how it's supposed to be. Officially the i9-7980X should only boost up to 4.4 GHz on two cores in Turbo Boost Max 3.0 and up to 4.2 GHz in Turbo Max 2.0.

4.2ghz is benchmark boost on all cores that iv been reading about in the leaks so far.
So we know it should overclock to that much on all cores atleast.

Doesn't sound right. More likely a software reading bug.

It is a pretty high TDP, 165W. I wouldn't be surprised if the "stock" all core boost was 4.2GHz on the Apex.

I wonder what Silicon Lottery will charge for a chip like this clocking close to 5 GHz

Soo its look good: hard overclocked 1950x cca 4300 p. in cinebench. and this unitel 18 core show 4200 on 4,200mhz.. maybe 4500-5000 points on cinebench with happy gold sillicone:rolleyes:

1000+ point more with 1000usd more:D:D ... but all this setup need and will need loudy aio water cooling(150usd) or custom expensive water cooling 500usd more

just imagine how many watts when you will run wcg or boinc/folding avx, .. its like big radiator in your room , or you need aircon

Clearly thats the intent there. You pay 1USD per cinebench point :-D

It will no doubt OC to 4,2GHz on all cores without any issues. Except at those clocks the power consumption will be perhaps on par with 12core clocked to 4,6.
We shall see... Bring on Monday. I cant wait to lay my filthy hands on some shiny 7940x:D

I cant wait to see the effects on the ozone this will have at 4+ghz. Or on the global warming.

Except for those of us who still need decent single threaded performance the 7980XE etc... are far superior to EPYC or Threadripper because you're looking at 2.8ghz Haswell IPC levels (i'm guessing ~150 cinebench single thread score? Around the same as the stock 3ghz i7 5960X.) with EPYC (not to mention you're limited to server mobo choices and ECC memory for the most part. Or if you go for Threadripper instead to fix that problem you're still only at ~3.9ghz Broadwell level at best since finding an 1950X that clocks higher the 3.9 is like getting mauled by a Unicorn lol. Meaning you're still looking at roughly stock speed Broadwell IPC ~165 point Cinebench single thread score etc...

Meanwhile benchmarks of the 7980XE show it getting roughly 200 points in single thread Cinebench 15 just with standard stock turbo boost where it boosts like ~6-8 cores to 4.2ghz-ish or whatever and leaves the rest in the 2.6 to 3-something range. I saw another benchmark of a 7980XE with all cores pushed to 4.7ghz with pretty high voltage and high end water loop and it got 206 point single thread R15 result iirc. That's nothing to scoff at frankly.

And this isn't even mentioning that 4,200 for a 24 core EPYC still is quite a bit lower than the 4,700+ that 18 core 7980XE is getting with a proper overclock put on it. Plus if 24 core EPYC is only ~1,000 points over 12 core 1920X Threadripper then i wonder if even the 32 core EPYC can reach ~5,000 or not.

Problem is that 7980XE can do everything great while AMD's HEDT is only good at one area. Then you get apologists screaming "HEDT is not for gaming" thus accepting that Threadripper is a one trick pony.
I guess we can call the first Core i7 processors a one trick pony. The architecture needed time to mature. Zen's SMT just needs time to mature just like the first Core i7's hyper threading. The difference is it cost $1000 more for 2 more cores. That $1000 can be put toward 1 or 2 high-end video cards. ThreadRipper has Broadwell IPC and sometimes faster in professional applications.

Comparing the first generation Core i7 processors. The Core i7 930 was getting whooped by the Core i5 2500k. Now it's on par or faster at stock

Sorry I don't want Ivy Bridge-Haswell level IPC in 2017.

You can game on anything. Nobody is saying you can't. It is up to the consumer to pick the CPU that will best compliment their usage. I game 80% of the time I am at my computer with my 6950X. That other 20% is video encoding though, and I put more weight on my encoding times than I do the extra FPS a 7700k would of brought me.

18 x 4200mhz + 4000C17 > 24 x 2800mhz + 2667C17 by ~40-45%... ( higher IPC )
Apparently 3400-3600mhz ( at 1.40v ) on the NB Clock for Skylake-X is possible on water.

It's most likely Asus Multi Core Enhancement. I was able to clock a Xeon with a 2.2Ghz Frequency to 2.8Ghz with this feature. It's likely the same option in the BIOS allowing this CPU to be clocked much higher than stated base frequency.

There is plenty documentation online for those who aren't familiar or haven't used ASUS/Asrock motherboards in the past.

Hope that helps.

But with the aforementioned feature, Xeons can be overclocked on certain boards.

Using an ASRock one, but seems to be a Intel based feature, or at least its a lot newer than a AM3+ system. Anyway, they are made with reason to clock so low. How long does the Cinebench test last? 30 seconds? I wonder how the motherboard didn't power throttle.

When I was using my Rampage IV Black Edition with a Xeon E5-2673 v2 which I overclocked it a bit using the BCLK but it barely overclocked and only 2 cores would run at that speed. I wanted a E5-1680V2 but they cost too much. I noticed I didn't need a HEDT so I sold it and built a 6700K rig.

It was a V4 14C Xeon at 2.8 GHz; It's not a 7900x @ 4.3. You don't seem familiar with this sort of thing if you believe a Xeon at 2.8Ghz would cause throttling. They run 24/7 with total system usage of ~250W per rig CPU only.

V3 18 core Xeons could run up to 3.6 if using the right microcode. It was patched with V4 but V3 18C @ 3.6 is still pretty quick.

Bruh, i am aware of the specifics in this matter, our company is building a datacenter right now, and we are running E5-2660v2 cpu's. Server boards take a lot more grunch than normal ones. Still, the EOS CPU cables are rated for ~150W each, and the 7900X at 4.7Ghz was already pulling those 300W. Now, increase core count by 80%, and overclock again by a hefty amount. It will probably go over 350W. It won't melt them probably, but for sure it will cause problems under prolonged usage. Oh, and i want my fried eggs done well.

Also, there was X79/X99 hacking for Xeons, which included overclocking.
