Coffee Lake 8700k to offer an 11% jump in single core and 51% jump in multithread

Then why put more cores on the silicon more CPU`s when all we want is one big one clocked at 10ghz by know. Back in the early days we were told they would just get faster and faster in terms of clock speed, on FSX release we were looking forward to the first 5ghz stock clocked CPU`s they never came.

As I mentioned, Moore's Law is about transistor density. As you get more transistors, you get more cores, cache, etc. While smaller transistors can support faster clockings, it's not the only limiting factor.

About a decade ago Intel and AMD made some unpleasant discoveries regarding current leakage, heat, etc. as they were passing 3Ghz and raw clock speeds have more or less stalled out. It's not surprising that these things would occur - planes got faster and faster until we got above Mach .85 and then the fuel consumption (never mind heat and materials when supersonic) stopped that march forwards.

It's also worth remembering that "we" is a very small group. Most computer users prefer lower power consumption and more cores rather than a single monster-clocked core. It would be far cheaper and easier to rewrite the sims to handle multiple cores better, than it would be to engineer such a CPU.

Cheers!

Interesting they are sticking with LGA1151. They usually switch it by now to ensure people keep buying MBs.

But I doubt Z170 chipsets will be compatible irregardless. 

 

Did i miss something? From my actual knowledge of the subject z270 won´t be compatible either...

Depends which CPU. According to this page, some can use 270s some must use 370. Essentially I3s.  But who wants an I3 anyway.

I find the 6 cores more enticing than the IPC.  8700K at stock clocks 6 cores at 4.3Ghz  with HT and turbo enabled, IMO that kicks serious butt for out of box.  My 4 years old 4770k @4.5 OC finally seems to be looking its age, though I won't pull the trigger on a new build just for FSX.  Sure it's some performance improvement, but considering that alone, for my needs, it's not worth the build cost.

Already buying some parts to fully replace my 4790k @ 4.7Ghz build, which has served me very well. Already bought 32Gb DDR4 3200 and a 4Tb WD Raptor just for Ortho4XP goodness. Unfortunately need to wait a bit to buy the MoBo + CPU. 

The only thing I will be maintaining from my current PC is the 1080Ti, the SSDs and, of course, Monitor + Oculus Rift!

tgcbraun give me some feedback about your upgrade please, since im also thinking on a CPU upgrade to feed my hungry 1080 ti, what's the behaviour of the 7700k compared to 4790k in simming?

 

Thanks.

Hi, I wanted to buy the 8700k, but it is not available in Germany, so I ended up buying the 7700k. I have only installed XP11 until now, because I am waiting for P3D v4.1. I did notice a good FPS bump of about 30% and am able to mantain 40-50fps, for example, in London with the beautiful FF 767-300, Aerosoft's EGLL, Ortho4XP, World4XP and online traffic. Loading times are also better!

Besides simming, the system feels much snappier in general. 3200 DDR4 makes a good difference when compared to the old 1366 DDR3!

Make sure you're actually running the RAM's appropriate XMP profile for that speed, else it'll just be running a default 2133 out of the box :)

Yes, first thing I did in the BIOS. Thanks! :)

Thanks tgcbraun, i probably going to wait for the i7 8700k, its not available yet in my country also, but i can wait :)

i was gonna buy it until i watched this video and read that article,ya you can do 5ghz on water, but will more than likely need a delid to keep temps under control, thats what i had to do to my 7700k. i use my 7700k pc for p3d 4 and my ryzen 1800x for x-plane 11 and everything else. intel is becoming a huge let down to me at least. if i am not dead, zen 2 comes out in january with a die shrink and hopefully higher clocks.i honestly think amd has ryzen locked to not be able to go over 4.1 to 4.2 ghz. zen 2 will probably open the flood gates for clock speed. but if intel does stop disclosing clock turbo boost clock speeds, people are more and more likely to end up with a dud overclocked cpu. for people that complain they lost the silicone lottery now, wait until the disclosure.i was an intel word not allowed most of my life, but i am about ready to run the other direction. we shouldn't have to delid a cpu to be able to get max performance, thats complete bullsh@t.

IT overclos easily to 5.0Ghz as per this report.

But that review says that at stock speeds, on auto settings, it ran at 90C under load! The best they could get, with manual voltage selection, was 86C under load at 5GHz - still very hot. They said that it doesn't scale so well after 5.0GHz, with voltage requirements going through the roof to keep things stable.

Why does Intel insist on unnecessarily limiting their CPUs with poor TIM?
