3080 performance with different CPU'S

[Bearskin]

I have been researching lately how much my 3770K is bottlenecking my 2080 in VR and have come to the conclusion, that if it is, it is only by a small percent so its not worth shelling out hundreds for a new mobo. cpu and memory.

 

 

Here is a review for everybody who is in a similar position as me, wondering if a CPU upgrade is worth it for a "gaming only" PC in VR or 4K.

I upgraded from a i5 8600k to a i9 9900kf. As the core speed is almost the same, I didn't expect a great difference in DCS. Now it is exactly as I expected. The frame rates are very much the same.

 

The next step will be a 3080 graphics card. That will certainly increase the frame rate, compared to my 1070 ti.

[Krupi]

Unfortunately that test is not particularly valid as DCS is CPU heavy. In the article Flight Sim 2020 which is also CPU heavy was omitted from the test for that very reason.

 

That is a shame as I would have liked to see the results on Flight Sim.

 

Still thanks for sharing, it has given me food for thought as I am debating upgrading my i5 6600K to a R7 4XXX or i7 10700K in anticipation of the 4K Reverb G2.

I upgraded from overclocked @4.5GHz 3770K to 10700K (no OC). 2070 Super GPU in both cases.

 

 

Night and day difference. 4K w/ Track IR is now my default. The 3770K was painful in comparison.

but for 10th gen you had to change the board as well because of the 1200 socket, right?

so also different chipset, different ram...

 

does higher ram speed make any noticabled difference in dcs?

AMD will be announcing Zen 3 in two and a half weeks. And... it is going to be good. Very, very, very good. Will it beat Comet Lake in gaming... yes, I believe so. Will it beat Rocket Lake? Maybe, but even if it doesn't it is likely to be a dead heat in anything above 1080p. Big IPC gains and closing the clock speed gap with Intel by another 200MHz or so.

 

I would be tempted by a 10600K, but knowing Zen 3 is coming out I think it will be a no brainer. (Well, only if you intend to upgrade that is).

[Bearskin]

This is another benchmark I saw a few months back, unfortunately there is only one 4K benchmark @ 2.07. I am not saying that you should adhere to these as it's your choice, I am only giving people what Krupi said "food for thought". Also in the first Toms hardware review I posted in my opening post, it is also worth noting the 4770K is the only set up with 16gig memory.

But it's not, ironically, "4K". Reverb G1 or G2 is 2160x2160.

 

Industry norm for 4K is 3840 × 2160 for TVs and monitors.

For VR, tests seem to indicate it does make a difference. There was a YT video of side by side game play with different RAM speeds. But I can't seem to find it now.

It's actually more than 4k.. 2160x2160 = 4,665,600 per eye (9,331,200 total)

 

4k monitor 2160 x 3840 = 8,294,300 total

Well aware, hence the "ironically" The industry norm for 4K is what i wrote.

It is valid I agree, I worded that incorrectly.

 

Regardless of the game performance 4K is GPU dependant I just wanted to point out that the games they show are more GPU than CPU based regardless.

Yup, would love to see DCS stats.

I went from an i5-6500 and 16GB RAM to a 3700X and 32GB RAM (2060 Super in both) and the difference was equally notable. 1080p for me.

 

I'd like a 3080, but then I guess everyone would.

[Panthera_Tigris]

Upgrading your CPU will only make a difference if you are CPU bottlenecked.

 

Most games are not CPU bottlenecked, but DCS in VR is not most games lol. DCS and IL2 are most def CPU bottlenecked in VR so upgrading CPU can significantly improve frame drops.

[Mysacina]

I am curious to see difference in 2k between 2080Ti and 3080 If its worth to go for 3080 or not.

[Waxer]

You mean in DCS? Probably marginal. I think 3080 is really ideal as a 4K card. But sure... let's see the actual results. We'll find out soon.

My 'gut' on the Intel side is that any architecture before the "* Lakes" is hurting your experience and from ~6th/7th generation up scales similarly to the Ryzen stuff. That's totally speculative on my part so take it with a grain of salt.

 

 

In my experience my 3770K was very bottlenecked by the 2070S so 3080 is going to make it worse of course. With my new CPU the 2070S is bottlenecked but very playable.

Thanks for the link reece146, just for the record I have no interest in a 30 series card. I guess the title came about because that is the card in the Toms hardware review, so sorry everyone for any confusion.

 

 

A few weeks ago I got a mate with the same 2080 as mine (mine has a slightly faster factory overclock) and the Rift. He went from a i5 4690 to a 9900K, Aorus Master and 32 ram @ 3200 a few months back.

 

 

So we set all the settings in DCS identical but he liked his 1.8 DP so I said leave it then as your rig should be able to handle it. So my DP is at 1.5 and we went on the same multi player server. Set up the Hornet and started down the taxi way. I was getting a solid 45 FPS. I asked what he was getting and he said 34FPS. He switched to 1.5 DP and went up to a solid 45 FPS.

 

 

I have been chomping at the bit for a upgrade for ages now, and if I still played non VR games I would have upgraded last year probably, but I think I am going to hold on until the new reverb comes out and see what the reviews are like and get that instead. I will probably need a upgrade in the not too distant future if I get the Reverb G2.

Getting rid of RAM-to-CPU bottleneck works too, the processors controllers will not throttle back the buses including CPU-to-GPU and everything will run faster, including the GPU, I experienced this myself, so it is worth upgrading the RAM and optimize it for whatever CPU you're using.

 

I noticed that in this video there is no mention of the Ryzen 5600/5600X and I find it weird, since it is the root gaming CPU from AMD, better pay less for the CPU with near equivalent performances in gaming even at 4 K and get a better RAM kit for it.

 

What I can say about running 4K 2 X MSAA tests from upgrading from a 3600X to a 5600X: CPU upgrade, <> 21% gain, RAM uprade: 6.04%.

 

For Intel users: The latest NVIDIA Game-ready driver for RTX 30 series is available now.

I've got an i5-9600K that I run at 4.8Ghz, I can't get it to run any higher as it will not boot. No matter what voltage settings I change, this is the max overclock I can get out of it. My cooler is no slouch either, it's the Dark Rock Pro 4 which happens to be one of the better air-cooling solutions. 

 

Anyone here have any good recommendations of upgrading from an 9XXX series i5 for DCS world or is it simply not worth it? I'd like to get to 5 Ghz somehow.

[Harlikwin]

So the upcoming 11 series from intel is supposed to have about a 30% IPC boost over the 9 series. Plus default clocks are a few hunderd mhz faster. So thats what I 'm waiting on.

My 9700k only goes to 5ghz before going less than stable so it sounds like you are in the ballkpark, when I was aircooling it I only could get 4.8 stable, watercooling helped me get to 5, but past that I run into issues.

I don't want to switch boards, so a 9XXX series Intel processor is what I'm shooting at right now. I could probably get a second hand one for a decent price now. However I don't know whether it is worth the upgrade? Should I just buy a watercooling solution first?

I honestly couldn't tell you, isnt the 9600 a 9th gen? If you are looking at something like a 9700k then I doubt you'd get much more performance, certainly not enough IMO to warrant an upgrade. Rembmer DCS is basically a single core sim for now, so extra cores won't matter, hyperthreading won't matter etc. So the only 2 factors currently are ICP and overall speed.

 

As for watercooling, it might help you clock a bit faster, the main upside IMO is its more quiet. Also, stay well clear of Corsair. I still can't their software to work 6 months later and countless tech support calls and threads. (cooler works, but its stuck at 100% constantly).
