Nvidia 780 and 780Ti. What's the difference?

Recommended Posts

If I was to splash out on this upgrade from my 660Ti, would the 780 do or do I needs to push for the Ti? The price differential is significant.

I'm running an i7 @ 4.0

Spec announcements are right around the corner for the 780Ti Classified as well.

I don't have both cards to test the exact price/performance ratio, but in hardware, when you pay more, you get more.

Or get an OC 770 to get close to the 780...? The problem with comparing GPU's is that you start thinking you might as well go one step up and get the better card but... then you might also go one step further to get an even better card. This also works the other way around. I was thinking about a GTX780Ti but the extra cost doesn't really justify the purchase over a GTX780 OC... but then I might as well save some more and get a regular GTX780... but then I mighst as well save some more and get a GTX 770 OC... but then I mighst as well save some more and get a regular GTX 770... And before you know it I might as well keep my GTX580. ^_^

 

Seriously though: I think I will get a GTX780 (no Ti) but I am still considering a GTX 770 OC (also because of the 4 GB VRAM... which I might never really use completely... and the slightly lower price...)


when you pay more, you get more.

 

Usually true (though not always) but the important question is if the extra bucks justify the extra performance. Would pay 50% more for 25% more (theoretical) performance? When you look at benchmarks the Ti is faster but not by that much. Sometimes a manually OC'ed GTX780 can come even closer. Imho the price difference between the two cards is too big to simply go for the faster one.

It's not possible to get close to the GTX 780 by overclocking a GTX 770, they both have different architectures, and the GTX 770 is hampered by its 32 ROPs and 256-bit bus. The GTX 770 is already an overclocked GTX 680, which means that you cannot increase the clocks much higher until you hit the GK104's limits. The GTX 780 is a binned GK110 card which is a lot more stronger, and the difference really shows at resolutions 1080p and higher. The GTX 780 Ti presents the full, unadulterated GK110 architecture, which gives it the edge in shading the texture performance.

 

As for extra bucks justifying the extra performance, of course this doesn't apply to the high-end GPUs, but the fact that when you pay more, you get more is still true, even though the price/performance ratio becomes more uneven the higher you get. Those who want the best will have to pay a premium, but they will get the best.

I was in the debate over 770, 780 and 780 ti. After lots of research, asking questions on EVGA, Overclockers, ROG, and a couple of other forums, as well as studying all about GPU architectures the final decision came down to price vs preformance and what my future intentions were.

 

I decided against the 780ti because the chances of buying a second $700+ card was not likely. However I would buy a second $500+ card in the next couple of months. Since I run three monitors running an SLI system is beneficial. Single monitors do not gain allot from SLI. Again just my IMO.

 

Also note getting the OC cards preform much better on overclocks if you intend to put them on a water cooling loop. IMO if you are not intending to use a WC system save your money and get a lower clocked card.

 

Mr Chaotic hit the nail on the head with the 770 being a tweaked 680 statement.

Thanks!

 

I'm hoping that it will give me the same relatively fluid experience I had with FSX. My settings I would say are medium to high, and although my performance is 'okay', I experience what someone else accurately described as 'microstutters' - it's not the fps necessarily suffering, but the fluidity. I know exactly what he means. Hopefully the video card boost will iron those out.

In P3D v2 the card will not iron out the microstutters. I have a GTX780. P3D v2 is smooth but not (entirely) without microstutters. P3D v3 still has a lot of bugs or let's say inefficiencies in the code which have to be sorted out before getting a really great experience from the sim. This will take some time... However, it has great potential...

Well, my perf isn't horrendous at the moment, it's just not fluid. I suspect the new card may help

Well, I installed my new GTX 780 tonight. I was previously running a 660Ti.

 

Definitely a noticeable difference in smoothness. With the 660, performance was a bit clunky, sticky, stuttery.....not horrendous, but not ideal. The 780 has mad the experience noticeably smoother and more enjoyable. Not a particular boost in frame rates....generally bounces around between 20-30 with a lock at 30. I'd say my settings overall are in the mid to upper-mid range.

 

I'm not entirely sure that all of my graphical settings are ideal but I'll wait until the NI settings have been determined whenever that may be

 

Definitely excited about the future of p3dv2. It's a bit rough around the edges but hopefully after 2-3 patches, FTX, the REX makeover and decent aircraft we will all be happy campers

Hmmmmmm… did you change a few settings or did you leave everything as it was? You would expect being able to turn on a few more options?

Is that 20-30 frames with a payware airport or a heavy aircraft? That seems to be a bit low otherwise.

 

I have a GTX780. FTXG is installed. All sliders to max expect for Autogen at very dense, Shadows only for Aircraft inside and outside, buildings (only cast) and terrain. Shadow quality at mid. AI traffic at 30% and Road traffic at 30%. I get around 40-50 frames almost everywhere. Almost never drops below 33 frames when locked. Even over cities with heavy autogen or with the ORBX PNW scenery.

Last night I exclusively flew around the Reykjavik FTX free demo area.

 

FXAA On

Vsync On

Reflections Off

Shadows on for a/c only

 

Scenery Complexity High

Mesh 75%

Water high

 

Can't remember the rest

 

.cfg is default. No changes made

 

Cleared out the shaders folder before running the new card

It is for me. I'm not too concerned with fps is my experience is smooth. But if others with similar setups have higher frames, it may just be the way my settings are configured, which at the moment is on a wing and a prayer

That was why I asked what I asked. It seems to me you should be getting better results, specially with your (very) medium settings. The big question now is what CPU you use and at what speed!
