upgrade intel i7 4790k to Intel i7-7820X

Are you overclocking your current CPU ?

Might be cheaper to OC it and wait a while until something awesome comes along

I'll plan out my next Rig upgrade, once I see the VR Gen 2. I'm sure it'll have a HUGE requirement, both CPU/GPU.

The most meaningful change to come in newer VR iterations is native resolution, which like even for 2D gaming is really only effected by the GPU. The only point at which the CPU demand will go up is in software/games making use of more threads, or some massive increase of average object counts which is a completely independent variable of headset capability. Case in point the 6700K and 7700K have pretty much the same IPC, but the 7700K is clocked higher and 5GHZ is pretty much the ceiling given thermal constraints.

No, I dare to say it would be a dramatic downgrade !

 

You will not be able to overclock that 7820 to a single core speed that could match your very fast 4-core 4790k if you also overclock that one.

 

Given how hard it is to cool the new i7's it would actually be foolish to think so.

 

Stick to what you have, overclock it and be happy that you outperform any new i7 in IPC with a FRACTION of the heat and power consumption involved to oc those new 4+ core i7's

 

If you want brutal performance for almost fair money, look my sig, that is maybe the last CPU Intel did only for gamers imho...and even that is nonsense with your CPU...stick to what you have and wait for better times..ehhm CPU's

One thing thats not true .

if anything newer gen core series from 6th and 7th gen are more efficient at cooling than their equivalents from 4th generation ( or older) under various conditions, be it idle or under workload. In this case it is not Intel Marketing BS.

6th Generation 14 nanometer: i7 6700K / i5 6600K (TDP 91W / Idle 2W)

Tcase (CPU temp) = 64C

Tjunction (Core temp) = 69C

Tj Max (Throttle temp) = 100C

4th Generation 22 nanometer: i7 4790K (TDP 88W / Idle 2W)

Tcase (CPU temp) = 74C

Tjunction (Core temp) = 79C

Tj Max (Throttle temp) = 100C

OT = 7820k ! not 6600k/6700k/7700k, but even those are beasts to cool when overclocked to 4.8 or more. All those "Past-SandyBridge" Intels are tough to cool. Those new i7/9 especially when you aim for many cores and 4.5+G = 350-480W..that is a totally different ballpark of numbers. That is what I mean.

Okay guys, thanks a lot, I'll keep the CPU

I just wanted to find a way to improve the FPS, for DCS, especially the Normandy map

What about to replace the GTX 1080 with 1080 Ti?

Or, i should better wait until 2018, when Volta arrives?

Lenux,

Your i7-4790K and GTX 1080 are about perfect for DCS. Like everyone else says, buying a vastly more expensive CPU will not improve performance any because DCS only uses two threads.

A Core i5 is fine. Even a fast i3 is probably very good these days. The extra L3 cache from an uber-expensive CPU won't help gaming performance.

On the other hand, you may be able to get more FPS out of a GTX 1080 Ti. The regular 1080 you have is great, I only have the 1070, but it's great for Normandy, Nevada, and just about everything else I throw at it at very close to max graphics settings. The regular 1080 is only slightly faster than the 1070. So, your system sounds about perfect to me.

If you're having framerate problems, it's because of how your system is set up. Drivers, UEFI/BIOS settings etc. Not lack of sufficient hardware.

Keep what you have and enjoy the sim, I wouldn't bother spending any more money at all unless you want a GTX 1080 Ti.

Peace

Thank you, Aluminium Donkey.

As I said, i'll keep the CPU, maybe i will OC it to 4,8 GHz

I don't know what to say about upgrading from GTX 1080 to 1080 Ti. I would prefer to wait until Volta comes out.

Offtopic question : i went from 40 inches 4k ( tv ) to 49, and later to 55 inches.

It looks great, the dpi it's okay, but i'd like to go a bit further :)

About 60, 65 inches. But the only thing i'm worried about is the dpi.

What do you think, guys ?

Right now, with 55 inches @ 4k, i have 80 ppi

Thats the same as a monitor 27 inches full HD

When I was considering a large screen to go for, I would have gone for the screen cichlidfan has. It was close to the same price as my 27 inch g sync, it was a close call which way I was going to go, very happy with the smaller g syncer.

The Philips BDM4065UC 40" 4k monitor, I think is the best of both worlds and a good balance for it's screen size and 4K res and speed, this should work well with your system, I would still overclock the chip a little to get the most out of you current system.

Philips BDM4065UC, 3840x2160 @ 60Hz, Response time - 8.5ms G-to-G (3ms with overdrive)

Also, here are a few settings to try Lenux, that should help with FPS for now. ED's optimising the sim, so things may get much better moving forward.

View distance to ultra or high when lots of AI.

Turn both shadow options in the settings to flat. This will help a lot for NTTR and Normandy.

6. If using Deferred Shading, you may wish to set your MSAA and Anisotropic values to zero, and instead enable these only through your graphics cards settings manager. Wags Post here

Edit

ViewSonic VX4380-4K 43in 4K IPS

This one looks OK too, little slow on the refresh rate still at 12ms Response Time (GTG) and I would only get a monitor with G sync after using it.

ASUS PG348Q ROG Swift 34in 100Hz G-Sync IPS

This would be the monitor I would perhaps go for next, bit pricey at the moment!

I really want to see, is the next gen VR with the latest samsung vr screens that are double the res of the oculus now. Few more years and VR will be the norm for a flight sim perhaps? Would probably need the next gen graphics card to run it tho at that res!

Its a pretty good screen, I like it

Wait for the coffe lake 8700k :)

That was only just an example. I think you dont understand. again Il repeat this is true to various models of thier repective genrations / model.

7820k also runs coolers than its 4th or 5th gen equivalent.

besides as other point out there is no need getting such an expensive processor with more physical cores or threads when DCS only uses 2 cores ( barely 2) 1 for pretty much everything, second thread just for for audio IIRC

4790k is still good and even then its simply better bang for yout buck to go for the 7700K ( or future 8700) have much better Price / Performance ratio than those enthusiast grade processors. Unless you are using applications day to day that make use of most or all cores, then yes. If not, then no.

Wait for the coffe lake 8700k :)

I do

Here are some details about I7 8700k

So, what do you think guys ?

Would the upgrade be worth it ?

Well, you have to change mainboard also as the sockets are different. Also some difference in memory requirements, especially if you are going to OC. I'm not totally sure this is a good move. I would wait for ED to release something that spans several cores first and give it a month in test. CPU prices tend to drop a bit as well. :smilewink:

I'm on a i7 4770K OC'ed to 4.8 and it works perfectly with DCS as long as I remember to change fanexpert from "silent" to "turbo" before gaming :thumbup: If not I will have a CTD in about one hour of gaming as the CPU starts throttling.

If I were you I would buy a water cooling for the CPU and OC it until it screams and run that until "burnthrough". Then you are ready for a new MB and CPU :D

Some people advise me to get the i7 7700k.

What do you think, guys?

looking at what you already have, if you have enough money, go for it but the 4790k is still good for most things...

So, the main difference between 4790k and 7700k is the 4,4 GHz vs 4,5 GHz (turbo clock )?

No no no. The i7 7700K is a new build but with almost the same performance as if you overclock the 4790K. But there are other differences also. See intel.com

But none of the new advantages to the CPU means anything for DCS. So you are way better off trying to max out your i7 4790K!

Would this cooler be okay for OC to 4,8 GHz?

yes, easy, but not as quiet as an AIO cooler...

A very decent cooler !

Some AIO's have loud fans ( Corsair for example ) that in the end will scream more than a Noctua imho. Unless you get a real good AIO I would be cautious saying the Noctua is louder, it could well be the one with less noise when pushed to the limit. For sure, both will not be silent when the rpm is fully UP.

The NH-D14 is totally quiet (without L.N.A).

It's rather funny how many of those adapters I have thrown away. I own, and have owned, many Noctua fans (I think I still have 3 or 4 in the original package ) and I have never used one of them.

Agreed. My DH-D14 is near silent without the Low Noise Adaptor. I think mine is still sitting in the box.

When I tortured that 1600X at 4G I could "just" hear the Noctua doing it`s work, the most silent airblower I personally have encountered.

My sons Corsairs H110 AIO is loud as hell, I had to change the fans ( 50€ for both ) to get it somehow living-room compatible.

Noctua is imho the #1 aircooler, 2nd to none in my world
