well thats what my original plan was tbh, wait for august and see what coffee lake can do. but with possible upgrade paths being more probably on ryzen as in not buying another mobo and just a new chip in 18 months i was also mulling that over. no matter what wont be buying until august.

and yeah iv said it elsewhere that i think intel dropped a clanger with kaby lake x as coffee lake should come out and beat it hands down for less money, and like wise for lower core count skylake x cpu's.

Aye, almost a certainly 6 core coffeelake will beak kabylake x and the 6 core skylake x while cost a lot less.

Waiting is the best option at such a time really. See what Coffeelake does, if it's another Kabylake to Skylake style upgrade you can still decide on Ryzen or the rest. Plenty of options in the next 2-3 months.

heard it first the new K SKU now only on x299 as Coffelake X

wouldnt suprise me if they reduced the K SKU and named them X editions on X299

So you would have just the 2 top High end I5/I7 as X parts no other K parts avaliable

this is why i hope intel get their act together this weekend at e3 and show us some proper info about coffee lake as now a lot of rubbish floating around muddying the waters.

hence the initial plan to wait for coffee lake before i jump in either direction, also means ryzen should be better developed and less temperamental with memory.

Man they will clock good dont you worry about that. Intel are not playing here. I am talking all Cores 24-7 prime non-avx stable. I dont run any benches on X299 Skylake X CPUs that don't benefit high cores and HT. 12 Core 5.9ghz LN2 NO PROBLEM and thats with quad channel mems 4000mhz C12-12-12-26 1T....... Remember 8 Core Ryzen is struggling to hit more than 5.2ghz+ with much lower RAM under the same cooling and benches............

Got to ask the question Ian, why are peeps struggling to hit 5.2ghz on LN2 ? I have no issue hitting 5ghz on the single stage in the pic below. Only hooked it it up and went for it last weekend (the pic is older lol), but had no issue getting 5ghz. Maybe Ryzen responds to sub zero, but not on LN2 ?

Maybe clock limit around that not actually 100% sure but non even at full pot are doing much more for benches like Cinebench R15 and high core and stress benches. I think scaling with temp is not as good as Intel parts. I can try around -50 and see what I can get next week to test out your theory. It could alos be that on full pot IMC gets too cold but again this is not normally the case.

No one runs their CPU's under LN2, Bulldozer ran 9Ghz under LN2, whoop de doo... it still rand like a therm-nuclear-reactor @ half that speed under anything less. its meaningless PR.

Would be good if you could test around -50c. Because if you come up with the same result i did last weekend..........................it could throw a whole new light on all sorts of stuff lol. As it happens, i havn't had the time to try anything more since but will do this weekend.

For me I have limited LN2 testing time these days. But many have benched it on HWbot and it seems the frequency for multi threaded benches really tails off at 5.2 or so.

Humbug your happy with ambient 3.9-4ghz thats fine Skylake X is faster and clocks much higher this is fact. Absolute fact. Anyone buying these CPU knows they pay top dollar for them but get top performance and OC. Price is not something I am commenting on simply performance.

Under LN2 or Phase ? i havn't looked or logged on there for years lol.

Panos · 9 Jun 2017 at 21:26

Bear in mind coffee Lake has new Z370 board, and the next one up will have next year another new board......

8 Pack · 9 Jun 2017 at 21:36

I barely go on these days. But LN2 those results did not check phase.

Coffeelake is a totally different proposition as it starts on Z platform yes.

Forgive me but you are starting to sound like an Intel marketing guy.

actually i do. i do benching for sport.

some people dont even care about what a cpu does under ambient cooling at all.

you hit 5ghz on a 1700 on phase?

8 Pack · 9 Jun 2017 at 22:01

No I am not at all aan intel marketing guy I support both AMD and Intel. I am simply stating fact. Did you try Threadripper or Skylake X???. I did. So for me you are not in any position to comment at all.

Constant supply of ln2 can't be cheap :O

Yes......................... that's why i asked the question

thats pretty impressive. mine only run multi core benches upto 4.8ghz ish at -130c and topped out 2c2t at 5.089ghz.

what board do you have?

i think i might have worded that i bit wrong. i was maybe saying that it is possible and if i could afford i would. I dont really do anything on pc but bench and forums.

Is it true that Global Foundries 14Nm is designed for mobile device use rather than desktop use? AdoredTV mentioned it in his previous video but couldn't find anything online.
Also if it is true would that explain the problems that overclocking problem and the 4GHz wall that everyone is experiencing?

I currently enjoy benching and although the most extreme I go at the moment is water, I wouldn't rule out progression. I find the information on competitive benching interesting.

I did consider a Ryzen system but haven't moved from my X99 5930k as I'm still open minded. I'm definitely not basing my decision on how the system will perform at stock, and I'm also willing to pay a premium for performance so bang for buck isn't all that.

I don't game on my X99 system, I use it purely for benching.
