The best CPU for DCS ?

[cugiahamchoi]

I need a new cpu for DCS upgrade and i have 2 option

 

6700K@4.7-5.0GHz or 5820K@4.5GHz

 

Anyone can help me make the most informed choices.

 

I need the best performance for dcs .

 

sorry for my bad english

 

Thank and regards .

For the best performance in DCS, compare the single core performance. That is what is most important, in terms of CPU, for DCS.

 

Btw, your English is just fine and welcome to the forum.

Just as a quick side note

 

there's literally no diference between 4790k and 6700k

 

the i5 5675c or the i7 5775c are as good as those, but lower clock speed

 

the 6th and 4th gen CPU don't waste too much energy compared to the 5th gen

 

if you can save money, go for the 4790k, which has higher boost clock then the 6700k

[cugiahamchoi]

Thanks all , very quick response :)

The newer i7 6700K (higher memory bandwidth, higher system bus, higner graphic performances) is the best cpu for gaming. 6 cores cpu is useless for now, notably for DCS. Most of the today games don't use more than 3-4 cores. DCS use less than 2 cores. As long as you reached 4+ Ghz.

 

The i5 6600K is the best for the buck for gaming. Cheers!

 

What will you purchase? A 2013 Chevrolet Corvette or the newer generation 2015 Corvette?

 

Welcome cugiahamchoi.

It seems our dcs only use 2 cores, so the higher frequency is much better for now.

And wags said the multi core isn't very useful for our simulator, but multi GPU is.

So they start to support SLI and Crossfire and still doesn't support more then double core.

I would say the best CPU is the most expensive you can afford...

 

but if you are asking about Skylake vs Haswell-E i would say Skylake , its a newer platform and cheaper than Haswell-E will lots of cool new features on the chipsets.

 

game-wise , i doubt there is a noticeable difference.

[Vladdo]

You'd be doing extremely well to get 4.7-5.0 out of a skylake cpu..

[ineth]

Both should get you where you want to be, from there i guess it is mostly GPU what makes the difference in performances. That being said i would like to add since both cover your needs in DCS try to get the better one for your other gaming needs. As i said. DCS seems to be covered either way.

This recent review gives you an idea of how CPU's scale across the board in DX11 and DX12.

[Barbajet]

The question you should ask to yourself is also how many processes are you running on the background on your Windows 10 ? Windows take advantage of all cores leaving more free cores to run only DCS.. 6 cores FTW :) even if DCS is running just on 2 cores.

[cugiahamchoi]

Thank everyone , i have got 6700K@4.6 + DDR4@3200 for upgrade from 1231v3 and got amazing performance . FPS increase around 40-60% in all DCS version . My VGA is 980ti . 6700K is a beast .

It would be better to use this test, which is performed directly with DCS world 1.5.x:

A comparison of CPU type performance from the post:

Just note that the i7 6700K is tested with higher speed than the other CPUs, so the result is skewed a bit there.

It is clocked ~12% higher, and also performs ~12% faster than the next CPU in the line (i7 5775C), so is probably almost equal in speed clock for clock.

[RoflSeal]

There is a test right below where all CPUs are clocked to 4Ghz

 

[cugiahamchoi]

Depending on CPU load, if a heavy load, the gap will be greater fps, you can check by raising lots of objects in a misson .

[T_A]

While clock for clock the graph may shows that 5775c is faster, just remember that 6700k is stock at 4ghz and can reach higher clocks while the others will struggle to reach the same high clocks.

 

also Skylake has a new platform with z170 chipset vs z97 and similar chipsets and thus have more features.

 

but IRL these differences mean nothing anyway and most CPU`s on that graph will feel nearly the same in game

[Fab]

I have desidet to get me a i7 6700K

 

What MB would be best choose ??

[SkateZilla]

Zen should be very competitive this fall/winter

 

It'll be a Bigger Upgrade in performance than the "Numbers" imply

 

ie For Me:

Mainly Going From:

8Cores/8 Threads Vishera @5GHz, Consuming about 325w Under Load

 

To:

8 Cores/16 Threads @ 3-4Ghz, Consuming about 95w Under Load

 

Now You have to Consider Performance Improvements:

Single Threaded Performance, Steam Roller is +7% over PileDriver, Excavator is +20%

Multi-Threaded Performance, Steam Roller is +15% Over PileDriver, Excavator is +26%

 

Now AMD has Already Stated, a Core/Thread Performance Increase of about 40% Over Excavator,

Which would put it around 68% Single Thread and 76% Multi-Thread, Above Pile Driver (Assuming you run 8 Core/8 Threads).

 

The Switch to SMT, will Run 8 Core/16 Threads, So Multi-Thread Performance will likely be higher than projected 76%

 

Test Samples also indicate a larger Performance increase than the 40% originally stated by AMD.

 

Which anything above +45% Excavator IPC would put the Zen CPU around the Current Offerings by Intel +/- 1-3% depending on Clocks.

PileDriver -> Intel 4xxxK Haswell is about +63% IPC

PileDriver -> Zen was Predicted originally to be about about +68% IPC, though now after samples testing, might be more like 73-75%.

 

 

That Alone isnt Everything, add the fact that we are moving to DDR4, PCIe 3.x, USB 3.x

Bottle necks will be removed

[Kev2go]

There is a test right below where all CPUs are clocked to 4Ghz

 

 

 

No 3rd gen i7, or 4th gen i7 comparison? 4770? or the 4790k?

 

 

 

 

In all hoenstly theres no real performance gap if your coming form a 4790k to the 6th gen.

 

suppose if your coming from a lower end computer or from a second/ 3rd gen i7 gen then its worth an upgrade.

 

 

 

 

 

6700k has going for it that it is compatible for usage for ddr4 ram.

New CPU's were focused on better embedded graphic and lower power consumption. The CPU raw power is pretty much the same since the 3rd gen of Intel.

Indeed...there has not been a milestone CPU released since the i5 2500/2600. Both those processors clock better than newer ones and are still highly recommended and sought after CPU's to this day.

better add that it's the 2500"K" and 2600"K" not just 2500/2600

 

locked cpus aren't that great, the IPC on the sandys is 5-10% less than on the newer ones...

 

AKA a sandy at 4.5ghz is more like a 4.3ghz skylake. the sandy will also use a lot more power to run at that frequency.

 

that being said, if you have a sandy, there's really no logical reason to upgrade to a skylake, unless you want the new features of a new chipset or motherboard.

The entire series was a milestone. As for features that depends on what one wants specifically.
