GTX 680 vs HD 6990 benchmarks and comparison!

[SkateZilla]

A. 6990 is a Generation Old.

 

B. 6990 is TWO 6970 GPUs in Integrated CrossFire Mode.

 

C. Dual GPU with DCS is On/Off, works for some and not others.

 

D. The GPUs on the 6990 are Downclocked to manage TDP.

 

E. 680 is Current Generation

 

F. 680 has the same amount of Shader Pipes as a Single 6970 Core

 

G. as pointed out a above in D, the 6970 cores in the 6990 are downclocked.

 

H. 680 Cuda Cores are More Efficient than the 6970 Cores.

yeah yeah, I get it, I'm just rather miffed about it that is all considering I paid top dollar for a capable machine to run this sim, am not exactly running mutli monitors, and other much more run of the mill less expensive cards work better. :badmood:

The card should rock for the sim but doesnt, fact of life, deal with it and adapt. :doh:

 

I have already made my mind up to ditch it and am placing an order for a GTX680 4gb card today.

 

I'll offload the 6990 to some BF3 playing noob tubing grunt :gun_rifle:

From my many years of virtual aviation, this is Flightsimming 101 lesson 1, nothing works the first time round, ever :thumbup:

[Vlerkies]

Don't shoot me please, but a last question.

 

I currently have a PCIe 2 board.

With this sim in particular, would a PCIe 3 mobo provide better performance with the 680 or is there nothing in it between 2 and 3?

3770K cpu, Intel chipset 1155

PCI-E 2.0 is fine... the bandwidth of it is not bottlenecked yet so you're fine with PCI-E 3.0 card in PCI-E 2.0 slot without any performance loss :)

Thanks

Vlerkies,

 

I'm just as sad the 6990 was limited in DCS, but I think you'll feel a lot better once you get the 680 installed. Look at the bright side, unless you play noob games like BF3, this will be a solid upgrade!

[Pilotasso]

the 680 nearly trumps the 6990, and you dont have to bother with SLi hassle.

[Vlerkies]

Yeah thanks chaps, I did the inevitable and ordered a EVGA GTX680 4Gb FTW card.

 

I have done quite a bit of testing this side to see if I could eek out a bit more performance out of the 6990, so it will be interesting to do a direct comparison in some fashion when the new gpu goes in. I'll report back with some results in about 2 weeks when I get it and the silly season is over.

 

Thanks for the advice.

[Vlerkies]

Right on :thumbup:

 

First test is in using the FPS Bench track that was posted here (the one where you on the runway and the heli's fly over you)

Had track Ir on and looked around a bit while on the runway and ran it for 3 minutes.

Admitably the 680 bench was slightly longer (6 seconds), so a few more frames, but the difference is plain to see.

 

This is on full game graphics settings, everything on high,turned on, and 1024 cockpit res, 8x msaa

Single monitor 1920x1080.

 

Money well spent.

 

I recorded another track of Sunset Sierra, a short take off and flight to waypoint 3. Have benched that on the 6990 as well, will run the same on the 480 and report back.

6990 = 2 Downclocked 6970 GPUs, 1 Gen Old.

 

680 FTW = 1 Overclocked 680 GPU, Current Gen.

 

As Xfire is either working or not working based on setups. It's Safe to say it isnt working for You.

 

Which means you're comparing a 1 Gen Old Downclocked 6970 w/ 2GB to a Current Gen Overclocked 680 with 4 GB.

[Vlerkies]

Been down that road for over a year SkateZilla, and actually in effect I am comparing 2 cards, be it 1 Gen older, that should work in tandem, but don't.

I gave up trying to get it to work is the bottom line. Flogging a dead horse, made peace with it.

Might just add my experiences, given I'm running a 6990 as well.

 

My setup is Eyefinity with 3x24" at 6048x1200 (bezel corrected) and two 8" VGA LCDs with Thrustmaster MFDs. Using SoftTH to transfer the MFD images to the LCDs (basically I setup a renderarea of 6648x1200 and stacked the 2 600x600 images on the RHS of the main display) I'm getting between 15-30 based on inspection. With SoftTH Crossfire is disabled so I'm basically running a 6970 2GB here, O/Cd to 950/1400 (i.e. O/C 6970). From what I remember most graphic settings are on maximum although visual distance is set to Medium with 2xFSAA, TSAA and MFDs at 1024 every frame. MSI shows the GPU usage at between 95 and 99% most of the time.

 

Given these frame rates are similar to Vlerkies' at 1920x1200 with over 3x the amount of rendering I'd suggest there is something in the engine giving the AMD cards issues.

 

Of course this is all totally (un)scientifically proven!

Cat 12.x Drivers had incorrectly written memory code from what i was told.

 

Hindered all 68xx 69xx 78xx and 79xx cards.
