Intel 12-core i9-7920X features a 2.9GHz base clock.

The SK-X will have Turbo Boost 3.0 enabled, where I think the Xeons don't? So they expect to pin single cores higher, which could mean their thermal envelope is being reached. At least for the requirements they've made on the Motherboard manufacturers. What it'll all-core on water to is going to be interesting. Base-clock matters, but the Boost Clocks are where the important levels are. (Base is a bit more important in server space, correct?)

That 4.2Ghz is the single core boost, all core boost is typically 500Mhz above base*

 

*For Xeons.

Okay, that makes sense. The general, all-core "turbo" is actually kind of important but never normally mentioned? (AMD isn't much better, but it's normally easier to find.) 

 

Still, if we assume the 7920X will settle in around 3.5 Ghz all-core, that's pretty much a 6x G4560 CPU. That's going to be toasty, regardless. Because Zen cores are quite a lot more power efficient (or, maybe more accurately, Intel pushed the Skylake performance by simply running more power through Broadwell designs), we're going to be seeing this comparison issue for a while. Though I really do look forward to the $700USD custom loops with 3 Rads to keep an OC'd 7980XE working. "4 GHZ ALL-CORE TURBO! It's only 750w at the wall!".

This 12c Skylake-X is oddly worse than the Xeon lineup clock wise which is not normally the case.

So people would still have the reason to buy Xeons for workstation and not i9?

Well, I don't know if 2.2 or what, but judging by how things were on the server side, a downwards slope in clocks is to be expected as the core count increases. There are issues with clocking more cores higher, and issues with staying within TDP for the platform. Overclocking may lift the second restriction, providing there are sufficiently "overkill" motherboards, and face only the first limitation, but for stock base clocks there will be a stricter limitation.

 

I mean, did anyone expect 7700K clocks in each of the 18 cores?

 

I'm really intrigued about how thinks will work out for Threadripper. Being 2 dies glued together^TM, in principle it will have no problem getting each core to 1800X speed, or even OC'ing to the same ~4.0GHz ceiling. However, that will come at roughly linear increase in power draw compared to the consumer chips. Even assuming heat dissipation is not an issue due to the larger surface area, will it cause excessive stress on X399 motherboards? Will we get another der8auer video?  Or is the energy efficiency high enough that most of the distance can be covered at the rated TDP?

 

If at the end of the day TR clocks higher at high core counts, we could have an interesting, non-trivial comparison between platforms, potentially with the single-threaded performance gap reverting as the core count increases. That would be would news for channels like LTT, as there would be a lot to discuss and explain...

Well Ryzen at 4GHz draws around 100A so TR might do 200A, which is totally fine tbh

You realise 100A would blow a fuse/trip the breaker when plugged into a residential socket?

 

Single Socket: 13A Max

Dual Socket: 26A Max

 

Nvm I was being dense.

I think he meant an extra 100W which makes sense for an overclocked 1800X; since stock 1800X draws as much as a 7700K.

 

So an extra 200W max on Threadripper to get all 16/12 cores to 3.9/4.0Ghz.

 

Arctic have already announced TR4 compatible AIOs, and their single RAD is rated for 250W DTP. With 240 and 360mm versions as well.

100A @ ~1.4v, is 140W. That conversion happens at the PSU, you're not drawing 100A from the socket.

An 1800X at 4GHz would be around 180W. Post is irrelevant @Drak3 just reminded me a PSU is essentially a transformer and I'm retarded.

No 100A 1.425V for an 1800X. So ~145W, with TR being about double that probably at 190W overclocked.

Yah I'm usually only 2-3 cups deep right now, but the lack of sleep made me need some more to survive in a decent mood

Let me be the one to say, that soldering would probbably fix that problem.

i7 7700k was running too hot? Intel said that users shouldn't overclock it.

i9 12c CPU running hot? lets decrease frequency of it.

 

So on 18 core model they will put it to 2GHz?

 

In next generation they will suggest users to manually downclock CPUs?

 

And generation after that they will suggest us to disable some cores?

 

Why aren't they soldering those CPUs ?? It's a serious question. 7700k was unabl to be soldered due to small die size. I don't think skylake-x is too small in size to be soldered ... is there any other problem?

I believe the "don't OC" was about a laptop device.

 

I also don't think the lack of solder is a "problem" for Intel. Yes, you can't get as much OC out of a CPU, but the TIM will last for a long time. That's the point of it and Intel is a server-maker first. The Zen die appears to have been thermal transfer/ability to be soldered comparative to Intel's current designs.

This lovely WCCF source says it has a max boost of 4.0Ghz.

http://wccftech.com/intel-core-i9-7920x-full-specifications-leak/

 

That is not good, looks like the AMD 12 & 16 cores will beat it and all the others up to 16 cores.

Multiplier goes up to 44 

Unless they meant all core boost which would be really high if it's at 4.0

How did you arrive to this conclusion based on the max boost clock? Max boost of the 7700k is 4.5ghz, and yet we run 5.2ghz on them all the time. The max clock speeds of these CPU's are going to be determined by the quality of your motherboard and cooling solution. You can still achieve 4.5ghz+ if you have a great board with a solid VRM and an extremely potent cooling solution. A delid is certainly going to be required to hit higher than 4.5ghz, but it's also not outside of the realm of possibilities, as Der8auer seems quite confident that his tool will be out soon.

 

Either way, AMD's CPU's will require the exact same conditions to be met in order to get all of those cores to 4ghz. Unlike Intel, 4ghz will be the limit for AMD, as even the consumer die's that these are based on, seldom go higher.

afaik it is 4.0 for TB2 and 4.4 for TB3 (2 core boost).

I think TB2 is more then 4 cores, but it really does look like that the 16 core part will be clocked lower then the 1950x in base and boost (except 2 core boost)

 

I did some napkin math and I figure the 14 core need to be at 2.7 or better (base clock) to beat the 1920x, and the 16 core part needs to be at 2.9 or better (base clock) to beat the 1950x. and the 18 core part needs to be 2.6 or better (base clock) to beat the 1950x.

 

so I feel that intels top CPUs will not be able to compete. NOTE: I can be wrong just a shot in the dark.
