Hi everyone

I currently run P3dV4 on and I7 5960x Cpu with emough memory along with a GTX 1080Ti Graphics card.

I am thinking of upgrading my CPU to an I7 8700k or can anyone suggest a CPU that may be a better fit for P3dV4. I have the $$$ but looking at value for what I get also. 

 

Thanks for reading 

i9-9900K

I'm on a 6700k. Upgrading to a i9 9900k with a new Z390 motherboard. Putting in a bigger AIO cooler as well. That i9 9900 with my 64gb 2666mhz of RAM should snack quite nicely on P3Dv4.

I hope you share your upgrade experience with us Eric. Will a 5.0 Ghz overclock be easily achieved or only on the "lottery" chips?

Until the general release of retail chips, nobody will be able to say for sure, but based on a long history of overclocking intel CPUs since the Conroe days, I'd say a 5 GHz clock will likely be trivially easy, given that Intel's two-core-active turbo mode on the i9-9900K is officially specced at 5 GHz right out of the box.  I wouldn't be surprised if it'll do all 8 cores at 5.0 on stock voltages with a half-decent cooling solution, although on that I'm on a little shaky ground as I haven't clocked one of their CPUs with more than 4 physical cores yet. 

I'm pretty comfortable betting on the come with this one...I'm with the rest of the crowd waiting on my preordered 9900K to ship.

 

The waiiiiiiting, is the hardest part

 

Cheers

The prices of the 9900 are just ridiculously high

What about the I7 9700k?

IMO just get the I9 9900K... you're probably going to have this new machine for 3 years, you'll be happy you spent the extra money, especially as P3D is CPU hungry.

5GHz on 2 cores out of the box! 
Maybe with water cooling and a good chip you'll get 5.5GHz on all 8 cores... who knows?

This guy's getting 6.8Ghz on liquid nitrogen!

The 9700K looks like a really strong CPU for P3D as well.  No hyperthreading (probably not a factor for simming with 8 physical cores available), and 12MB vs 16MB L3 cache.  Factory rated to 4.9 GHz (two-core) at highest turbo boost speed.  $420 for the i7-9700K vs $580 for the i9-9900K on release day.

Personally, I *really* want that extra cache working alongside some fast Samsung B-die RAM modules, as my primary goal is to smooth out the bumps from intermittent spikes in workload associated with autogen and terrain/texture loading and fusion.

Guess it depends on your reference point and your history.  I have three fly rods that i use a few times every summer that each cost at least as much as the 9900K.  Every 2-3 years I end up buying a pair of smart phones for my wife and I--that would buy nearly four of those CPUs.  My X6800 Conroe dual-core CPU was $1000 in 2006, and it was probably the most eye-watering single-step change to my (FS9) simming experience in 25 years.  The second most stunning was the next step up, another $1000 CPU, the i7-975 Extreme Edition Nehalem that was my first CPU that would actually run FSX without embarassment.  Since those two, it's been steady incremental progress, cheaper at each step, but not tremendously remarkable, either.  I'm kind of hoping that doubling my processor count to 8 cores with higher-than-ever overclocks made possible by a return to soldered IHS construction and better use of threaded concurrency in P3Dv4 will once again serve up some sizzle, but this time without the $1000 price tag.  If it does, I won't think it too ridiculous.  If it doesn't, I still won't have to wait until next summer to use it.  😉

Wont be long before the water cooled OC results start coming in...  If people are getting 5.5Ghz on all 8 cores on water then the I9-9900K is a bargain IMO.

Whats probably helping to achieve the higher OCs is the solder used to the IHS instead of lousy thermal paste from intel.  Of course also depends on having a good 12 power phase and high quality construction VRMs on the MB. Makes for an expensive upgrade but if the benchmarks prove anything, it may well be worth it for prepar3d finally. 

As a piece of caution: do not expect too much from overclocking the 9900K. Intel is playing games with those CPUs. They HAD to use again properly soldered IHS for this generation, as it would have been simply impossible with the approach they did in the last few years. Furthermore, Intels TDP specification of 95W for the 9900K is simply for the base clock of 3.6GHz, as soon as the turbo kicks in, 95W are an illusion. I doubt that with a normal standard cooling solution that 5.0GHz on all 8 cores is as easy to achieve as many here think. I guess, the heat produced will be at least comparable to a 8700K running at 5.0GHz on all 6 cores, and this you do not get cooled using a standard cooling solution. Certainly you can Forget 5.5GHz on all cores, this will be never the case for normal users.

Nice memory kit there Bob.  If I had that kit I would certainly try it at 4266 c17 or 4000 c16, as the quality z390 boards should be capable.

How can you read from "32GB DDR4 3200MHz" that this is a "nice memory kit"?
