No way are you going to get that kind of drop in power consumption, especially at the high clocks used on the i7-K CPUs, when using the same node (however improved it might be).

I was being kind. For the delidded Or should that be deluded.

I can't see coffeelake on a more optimised process, with less cores and no avx512 drawing more power / heat than an 8 core skylake x

never said it would, just wouldn't use a skylake x to make guesstimates

Source please? The only temperature assessments I can find are for the i7-7900X, which gets in the low 70s on air at stock (4 GHz) in Handbrake (let alone Prime or other more taxing benchmarks) and 90+ when at 4.5 GHz using a 240 mm AIO.

Hell the i7-7800X uses as much power undeer load as the R7 1800X despite having two fewer cores (at essentially the same clock speed)! Intel's rush for MHz is costing them in both power consumption and temperatures; it's pretty clear that AMD has the more efficient design, at least up to 4 GHz (can't test any higher since Ryzen doesn't clock any higher).

he mentions in the video

4ghz took 0.9v

4.8ghz took 1.2v, in the video review he says "temps sat around the mid 60s, with a few spikes to low 70s"

if you compare the 7820x at 4ghz to the r7s at 4ghz Intel actually draws less power than amd, power draw goes up a lot when pushing for higher clocks though.

Is Covfefe still looking like August, btw? I'm struggling to find any recent articles citing a release date other than 2H 2017...

Thought I saw a headline saying MSI leak intimated Q4?

So it's just a mention, no specific tests? Hmm, difficult to compare to anything else then.

Not according to Hardware Unboxed's two power consumption tests. i7-7800X has the same peak power consumption and higher idle power consumption (again, with two fewer cores).

Ugh. I don't really want to wait until Christmas :/

I thought someone mentioned October

one of the websites, can't remember which one now.

Computex 2017 Intel slide. Says Aug/Sep for coffeelake

it's his test of benchmarks, so it's fairly realistic in terms of performance, he got similar temps/frequencies on his 7900x test to others so it's not like it's particularly lighter than other reviewers tests.

worth noting though that hardware unboxed and most places are using prime95 and aida 64.

prime uses avx2 and aida 64 also uses avx512, meaning they will naturally consume more power than ryzen because it doesn't support these instruction sets.

technically it does avx2, but it's severely gimped for cost saving measures.

The charts they showed were for Excel and 3DMark, not Prime95 or AIDA64.

Ok that's better news

August would be nice, Sept I'll stretch to. More than that I'll buy Ryzen tomorrow

That does say the introduction date though. Notice skylake-x has May 30th and was released just under a month later.

If anything, this confirms that Coffeelake will not be released in August. If you add a month onto the introduction date you get September - October, and most likely October to match the Q4 from motherboard manufacturers.

Introduction may mean many things. I wouldn't, though, pull +1 month from thin air. Skylake released in August, so...

Take this with a pinch of salt so.

Manufacturer confirms Intel’s Coffee Lake Z370 motherboards are coming in Q4

Possibly, it might be October. It'll depend if the depicted August is a hard or paper launch. I love how he ends his post with please focus on Z270 - yeah right

Intel are rumoured to be releasing Z370 motherboards later this year - https://www.overclock3d.net/news/cp...releasing_z370_motherboards_later_this_year/1

Rumour has it that Intel is planning to release their new Coffee Lake series of CPUs alongside their new Z370 motherboard platform in Q4 2017, which takes place between the start of October and the end of December.

Previously, it was suggested that Coffee Lake was moved up for a summer 2017 release but this new rumour suggests that Coffee Lake may arrive later than expected, but still within a year of the launch of Kaby Lake.

That article is written from the same source as posted a few posts above, so nothing new here.

GAC · 29 Jun 2017 at 07:58

iv said elsewhere in this thread ( i think cant remember im old) that if that introduction slide is the public release of coffee lake news we could be waiting until oct or even november for launch hell looking at x299 launch and pre orders we could get pre orders end of oct and then have to wait a few weeks or longer depending if intel really are having issues getting stuff out again taking in to account what happen pre launch of x299 and the lack of cpus everywhere not just in eurolandia.

Simon Belmont · 29 Jun 2017 at 10:41

I hope this news is wrong? Don't want to wait until nov
