Remember tho, the CPU in the video was the 10 core 7900X, the 7820X has fewer cores, so it will run cooler, which means that 5GHz should be possible with slightly higher voltages

0.4 GHz extra is quite a lot extra just by removing two cores, but that still doesn't change the fact that Intel have given their sub 1K CPUs 28 and 16 lanes on a HEDT platform....

 

Purely because of the lanes I am going TR, I am not spending 1000$ (actually more like 1300-1400$ since I live in Denmark) on a CPU just to get 44 lanes. Their 7820X would have to be at least 30% better in single core performance to even get me to think about buying that gimped piece of shit. 28 lanes are simply useless for me, I would have to prioritize way too much and not make the system as I want it, while with a 1955 I have all the lanes I will ever need plus the programs I use a lot will be able to fully utilize 10 cores and I don't game enough for it to be worth giving up on the extra lanes or spend another what 400$ on a CPU. Ryzen is basically at Haswell IPC, so I will see a bump in FPS and better timings going from my 4770k (stock because shit happens) to a 1955 (OCed up around 3.8-4GHz).

I still don't get how it isn't enough. There's no GPU that uses more than 3.0 x8 in the wild at the moment and your PCH/chipset provides another 20-24 lanes for other add-ons.

I'm just here to drop in the "official" acronym list for products:

 

Haswell = HSW

Haswell Server = HSX

Broadwell = BDW

Skylake = SKL

Kaby Lake = KBL

Skylake Server = SKX

Broadwell Server = BDX-ML and BDX-DE (mainline and -D SoC).  Most people just call BDX-ML BDX because no one cares about the SoC.

Cannonlake = CNL

Cannonlake Server = CNX (cancelled?)

Icelake = ICL

Icelake Server = ICX

 

 

There, stop using weird shit like SLX or typing out Skylake-X

Yeah those acronyms can fuck off. HWE, BWE, and SLX forever.

Uhm yes there is

and just for fun then some SLI stuff with 8x + 8x vs 16x +16x, where you can see in some games you get upwards of 8-10 FPS more by running 16x 16x, while in other the difference is basically 0. I wouldn't mind getting another 8 FPS in some games.

And those chipset lanes don't go over in the PCIe slots, so if you use some for of expansion card then that would use the CPUs lanes.

I don't want to buy a 2k system just for the CPU two- three years later when I change the GPU/s to run into problems with them not being able to give me 100% performance because my CPU cannot provide enough lanes.

Ofc then we also have the fact that AMD uses the PCIe lanes to CF with, that takes up a bit of bandwidth.

Yes you get the chipset lanes, but those have a max speed of PCIe 4x. These lanes are typically being used for storage, internet etc.

NO ONE  WHO WANTS TO BUY AN X299 CPU CARES ABOUT VALUE

I know this is a hype thread, but that's gotta be one of the most fanboyish statements I've seen in a while.

 

But if we're talking HEDT platforms, it's going to be all about Use Cases & Total System Power.  Which we don't know until we have both systems available to compare.

 

Also, it's open mocking season on anyone talking 1080p gaming on X299.   We're just a couple of weeks before someone drops the stupid "7740k is the best gaming CPU!" article.

I mean, most enthusiasts who want to buy X299 CPUs don't really care a lot about value, they just want maximum performance

Hey, I am going to get an X299 CPU before I upgrade my monitor! lol (bcuz priorities)

But, but, the 7740X is the best gaming CPU, it's just not worth it

Pretty sure all broadwell-e from 6800-6950 all overclocked about the same 4.4 range avg

So off the mark it's funny  No, 4.4GHz was a golden CPU. Broadwell-E overclocked to 4.1-4.3GHz on average.... 

But if you read my reply carefully you will see that I said:

So because the CPU has fewer cores, it will run cooler which will allow you to increase the voltage (more than you could if you had more cores, because the CPU would overheat), so that you can get 5GHz

No, your not the only one. My Rig wants to be upgraded. I expected them to be out already, cant find anything so far.

I'll be up in about 8 hours as I'm getting ready for bed. But I'm definitely excited specifically for the 7820X which is the one I'm getting. My only concern right now is temperature. Performance will be great, but I want to see if I can achieve a high OC with a 280mm rad without upgrading to a 360mm, much less a custom loop. If temps are generally acceptable for high overclocks, I'll be a happy camper. ?

Exact same boat man.  I just upgraded to an upgraded h115i in preparation of cooling a 7820x.

From my understanding Der8Auer was able to push the OC by 200mhz by delidding+using Liquid Metal. The Cherry Picked CPU was able to OC to 4800mhz within the mid 80°C to low 90°C with AiO without delidding (on a 7900x). So i would expect atleast 4500mhz on a non cherry picked 7820x, delidded and AiO cooled.

People that say look he did it with an AIO in the video, erm would you be happy running 80-90 deg daily? I sure wouldn't...

Most people don't run Prime95 daily, but nice try @tom_w141  

 

Hell, most people here on LTT consider AIDA64 a load.  lol

 

I should add that if he would have run Prime95 with AVX enabled, that chip would have probably melted.

Ofc not, but you have to think that with Broadwell-E 10Core CPU's most couldnt clock that high under most available cooling solutions. Thats the story he is trying to tell with his Video. And having two less cores on the 7820x will most likely reduce the heat and voltage needed to clock relatively high with good temps.

It's that last 100 MHz that pushes every chip beyond the comfort zone for voltage and heat.

 

As you and I have both said previously in the this thread, 4.5 GHz and higher seems very realistic for average setups.  Even at a "low" 4.5 GHz, I'd consider that damn impressive.

Still likely to see upwards of 70 which is still on the high end for sustained usage, though as you say the higher temps are likely a result of pushing it to the absolute limit, when backing off 100-200 it should be nicer, for every day use I prefer to be below 60 but that's just me.

I'd be fine sitting at 70ºc all day every day. I see nothing wrong with that, and it's even less of an issue on a platform where people are more likely to upgrade more frequently anyway.

My point was I like being cool and quiet for longevity and noise. No doubt that AIO's pump and fans were screaming.

Not melted, fused with the AIO block. So it would have "soldered" itself. Sounds like the best way get that soldered effect if Intel won't do it for you.

Even with AIO fans screaming, the fact that he got a cherry picked 10 core Skylake X chip running Prime95 at 5 GHz is remarkable.  

 

I don't see a need to place emphases the little stuff as I don't think anyone here expects similar results without having pushed the AIO and ambient temps in the same manner.

 

I for one run a custom loop with 5 x 360mm rads and 25 EK Vardar ER fans.  I fully intent to run it at a very high clock rate while remaining cool and quiet.  I'm just glad that Intel will give me the option to run those higher clock speeds.  

 

It's up to the end user to determine what they are willing to do to take advantage of it.  It's not like there's a penalty for running a lower overclock.  The IPCs are still great.
