Titan X pascal 50% FPS increase over Titan X in P3D v3.4

Recommended Posts

Ran my standard benchmark test I've used over the years for P3D - see tests 26,34,35,36:

Here are the supporting test files:

However, two Titan X's in SLI did perform a little better when using SGSS AA vs. the single Titan X Pascal.

But but: £2,300 just for the one graphics card! Phew!.

 

At least, that's the Amazon UK price for it.

2,300 quid??! Are sure about that? For that price you can by return ticket to CA and pick one up at $1200. Go to nNidia's web site.

 

Cheers, Rob?

Interesting data as always, Rob.  Also a bit puzzling as I'm not seeing anything like that kind of improvement since upgrading to a Titan XP from a Titan X...only maybe 10-20% at best in my case.  I mainly upgraded for VR support and improved performance in some other games I like to play a lot, but of course I was secretly hoping for an improvement like what you're seeing in P3D as well.  I'm still on v3.3.5 but I wouldn't think that would make such a big difference.  I'll have to dig a little deeper to see what's going on with my system.

Hi Kevin

 

I added all my test data results including graphics settings, flight file.  The flight is a basic loop out of ENAT in the F22 -- that's been my reference flight. (no AI)   I used this location because it has a good balance of scenery/mountains/water where CPU and GPU would have a good equal distribution.  I didn't want a location that would be CPU bound ... so ENAT was selected.

 

Variances are P3D V3.4 and 376.19 drivers and of course Titan X vs. Titan X Pascal.  Also changed the AffinityMask to 21845 (accomplishes essentially the same as HT off only not done thru EFI).

 

Also saw similar improvements % in XP11.

 

Cheers, Rob.

Perhaps Rob uses 4K resolutions and Kevin not.

 

I have a normal Titan X with 3x 1920x1080 resolution.

8x AF / 4X MS

 

Probably no 50% extra fps if I would try a Titan X Pascal..

 

Rob , might it be that you have reinstalled the driver for the Titan X Pascal again and that is causing this ..?

I could really live with those ~120 FPS, line 31 and 32 results.

What a pity AA still has such an effect on even the latest cards.

Yes, silly. See Amazon entry below.

 

There may be other traders (probably doing "grey imports"  -- dodgy warranties that way) for less than that, but these things are always much more expensive over here! They may be trading on its relative rarity in the UK to date.

 

Anyway, I'm okay at present with my 1080, at least in FSX-SE. May consider upgrading later, maybe when I do eventually switch to P3D.

Hi Rob

 

Great tests ,

 

Am i correct when i say that it seems like your SLI solution (old TITAN X) from test 25 is about 15-20% lower than PASCAL TITAN X AND without Dynamic Reflections?

 

Thanks

About 16% yes, DR is fairly GPU intensive and the F22 canopy in my test flight will demo DR usage well ... I haven't tested the Titan X Pascal with DR off ... the levels of DR are:

 

 

 

Low: basic world features (ex: terrain, sky, water)

Medium: taxiway and runway features)

High: autogen buildings and air features (ex: stars, clouds)

Ultra: details (ex: particles, vegetation) 

 

Cheers, Rob.

Any reason you can't buy direct? http://www.geforce.com/hardware/10series/titan-x-pascal  (if you did want one)

 

Apparently the 1080Ti with 10GB VRAM will be out very soon, but it's going to be about $1000 ... I guess nVidia need the cash to keep pumping up their Shield product which seems to be NOT doing so well (nVidia refuse to provide sales numbers which is always a bad sign).

 

Cheers, Rob.

Not sure what you mean ... but I always run latest DDU prior to driver install of any of my GPUs.

Well, that link doesn't work for me, but the UK version,

http://www.geforce.co.uk/hardware/10series/titan-x/

does, and lists the Titan X at £1099, and doesn't have anything but a blurb for the XP. I guess it isn't released by GeForce over here yet, and that's why it's going at such a premium from importers. 

 

I expect it'll settle down to something more reasonable when it is released. I might consider it, when I move to P3D, but not if it doesn't have a notable improvement at 1080P (unless I weaken and go for a 4k projector -- though i'd have to pay for installation on top of its price too. I'm not attempting that these days. Too old and wobbly with a bad back and claustrophobia so i won't go into the loft, which would be necessary).

 

Thanks for the temptations though! ;-)

I love my Titans X Pascal... Ive also noticed a performance increase coming from two 780Ti's... I've water cooled them and temps are great...couldn't be happier... Merry Xmas!! Ho Ho Ho... the rest of my pc is coming next year when Intel release the 7700k...

You buy it directly from nVidia for £1099 - just got my one through yesterday.

Interesting. There it is just entitled "Titan X" not "Titan XP" or "Titan X Pascal", but it says Pascal architecture in the smaller print. So are ALL titan X's with Pacal? nVidia don't appear to list the Titan X separately like resellers do. 

 

So, maybe I was searching for the wrong thing. Amazon has Titan X's as low as £899, eg: the one below.

 

[LATER] Read the description of that card in the more detailed text below on Amazon -- it says "Maxwell" architecture".. So now I'm really confused. When buying a Titan X how do you know what you are getting? Does it say Pascal clearly on the box? It doesn't in the pic on a posting above.].

Pete,

 

What type of Titan X , Maxwell or Pascal is written on the box..

 

I have a Maxwell Version. Depending on the resolution you use ( 2k or 4K ) , the AA settings and other intern P3D settings related to the GPU, you will see an improvement.

Rob claims about 50% , but I think in my case perhaps 15-20% with my config.

 

I see no reason to upgrade from a Titan X Maxwell to a Titan X Pascal.  

But you decide for yourself.

Hi Rob,

 

Interesting set of results. However, I couldn't help noticing that test #29 compares very favourably with your latest batch ;)

 

(Note: Those with sharp eyes will notice that Rob tried my 'rogue' affinity mask value of 21760 with his 8-cored CPU without HT. Rob detected more long frames which hadn't been my experience, although the difference between our results were marginal. It remains unclear why my experience had been better as our Setups, at that time, were very similar.)

 

Regards,

Mike

Okay. Hopefully always in the adverts too then, though not necessarily very prominently it seems!

 

Odd that on the UK nVidia site only the one Titan X is listed, and that's just called "nVidia Titan X" just like many of the ads. The one there is a Pascal. I assume they are no longer supplying the Maxwell version so the resellers are just supplying older stock.

 

Thanks for the clarification. I have only recently got my 1080,. I see no need to upgrade again yet -- maybe if and when I decide to upgrade my projector to 4k.

Some of the discrepancy in these benchmarks may have something to do with the Bottleneck of a Third Kind. The first type is when the CPU speed limits the GPU. The second is the reverse. But the third kind is when the app needs more VRAM than is physically present on the graphics card. On lower end graphics cards it could occur at lower settings.

 

It is distinctly possible when running at 4K resolution with 4096 uncompressed 32 bit textures that this third type of bottleneck occurs. At that point the GPU starts using slower system RAM in addition to its faster onboard VRAM.

 

XP, for example shows VRAM usage when one adjusts texture complexity. 3rd party monitoring apps like Aida 64 will also display used VRAM on the fly.

Does it say Pascal clearly on the box?

 

Yes, it will clearly say "Titan X Powered by Pascal" on the box.

 

I know your an AI traffic kinda guy, that's mostly CPU intensive ... a Titan X Pascal isn't going to help much there.  More CPU and higher clocks will help for AI traffic.  In my testing .cfg link I provided, you'll notice that I have AI turned off, this is done so that testing is not skewed one way or the other (CPU/GPU) and my attempt to retain a balanced "flight".  It's the same test I've repeated over time as to give a relative performance compare.

 

For example, if use Orbx SoCal with FSDT KLAX and turned up AI, I'm immediately CPU bound and it wouldn't make much of difference what GPU I used.

 

Cheers, Rob.


 

 


However, I couldn't help noticing that test #29 compares very favourably with your latest batch

 

Test 29 is with SLI enabled and DR is turned off relative to test 34,35,36 which are single GPU with DR at Medium.  DR is a good test of GPU performance, Test #26 is a more accurate compare to test 34,35,36.

 

Long frames will be very specific to the flight path and location and add-ons ... I'll record my test flight and post video in case you'd like to use it for reference.  Part of that test flight is to fly thru a cloud as we know that clouds and AA settings can stress a GPU.

 

Cheers, Rob.

Why do you need that 12 Gbs Rob?  Am I getting a whiff of 64bits?  What are you guys cooking up and savoring over there?  :D 

Actually, just want to say Happy Holidays and thanks for doing what you do.  I tend to get a little bit of cheer when I see your savory posts.  Thanks and Cheery Holidays..

Hey Rob,

Been away from the forums for a few days (darn work stuff!) but thanks for your reply to my earlier post (towards the top) and the additional config and scenario data.  If I have some time this weekend I'm going to set up some similar test scenarios on my system and see what kind of results I get.

 

Btw I wasn't in any way implying that I didn't believe your results...I know how methodical you are with your test methods!  :wink:  I've had a nagging suspicion for some time that I've got a bottleneck in my system somewhere and that perhaps I'm not getting all the performance that might be available...not just in P3D but across the board.  Or maybe I just expect too much...anyway this might help confirm one way or the other or at least give some clues.

 

Happy Holidays!

Kevin

Not looking for believers, I just present my information ... if it's helpful great, if not, sorry, but that's ok too.

 

The problem with "bottlenecks" is that it will vary based on what needs to be rendered at any given time and location.  If one runs SGSS AA at high levels with dense clouds then the GPU is going to be the bottleneck but on a clear day SGSS AA works well.  If one runs high levels of AI and road traffic in a dense populated area like KSEA then CPU is going to be the bottleneck.

 

 

 


Why do you need that 12 Gbs Rob?

 

Well I had 24GB VRAM with my two (now "old") Titan X's.  But so far P3D/XP11/AF2 have not used more than 5.1GB VRAM ... but XP11 has used 16.1GB of VAS but ironically less VRAM?

 

Cheers, Rob.
