slower than the 580 (when both are overclocked). I'll provide you with benches you can run, so we compare the performance difference from MY previous 400$ 2gb 660 SLI to your 1100$ 6gb Titan.
Even though you're at an advantage, run any of the following benches below that you can run, so we would compare the two setups. 660 non ti SLI, VS your single Titan. (660 SLI = 580 SLI, and Titan = 780) Benches (Click to show)
What SLI issues are you talking about? I'll like to know them because i have 770 SLI and i myself don't have ANY issues with it, so please educate me since you know so much about it
. What you don't understand is that your Titan's 6gb, or the 780's 3gb V-ram IS USELESS! (single card wise). It's laughable how people take this V-ram thing out of proportion.
Look at it this way, you stated it yourself that you play at x2 MSAA on crysis 3 so you can get "playable" frame rates right? And that would result in about 1.2gb V-ram usage on average. That's exactly how it would also be for any other demanding Game that could require a lot of V-Ram on high AA settings.
Bottom line: You would still find yourself turning down AA settings to get playable frame rates BECAUSE YOUR TITAN IS NOT POWERFUL ENOUGH!
. And it's a FACT that turning down AA results in lower V-ram usage, so at the end of the day, you end up using about 1.2 - 1.5gb V-ram on average.
I apologize for the delay in replying.
Since when do Titans cost $1100? I thought the retail price in the US was $1000. If you're talking about the price that I bought it at, that's a different thing. But its still not $1100.
Also, I thought we were using the Titan's performance as a representative of 780's performance? Why did you get into calculating price/performance using Titan's price? We are not here to justify my purchase, but to justify it for OP whether or not he should upgrade to a $650 card from 580 SLI, which will be a $450 upgrade since he can sell his two 580s at $100 each.
I'm sorry but I do not understand how I am at an advantage. Can you please explain it to me?
About SLI issues, let me address it with a list of comparison between 580 SLI and a single 780 :
- more VRAM with the 780
- lesser chance of hitting VRAM wall with 3GB cards than with 1.5GB ones
- better acoustics with the 780 (1 card vs 2)
- better thermals with the 780 (1 card vs 2)
- better scaling with the 780 (1 card vs 2)
- less micro-stuttering with the 780
- less power consumption with the 780
- no waiting for SLI optimization
- GPU Boost 2.0 providing free overclocking
- all the advantages of Kepler vs Fermi (if any, I dunno)
About 3GB VRAM being useless, maybe single cards alone will not be able use it. But 1.5GB is definitely quite low for today's games, even for 1080p. So that VRAM is actually going to be used to prevent hitting the VRAM wall, especially with newer titles that are more likely than not to require more VRAM.
How do you know that even with minimum amounts of AA, newer games won't surpass the 1.5GB VRAM limit?
Thanks for finding and posting those scores here.
See this is what I was talking about. You are supposed to compare $400 660 SLI to $650 780 (instead of to the $1000 Titan). How much of a price increase is that? (62.5% if my math is not off. pardon and correct me if it is incorrect though.)
Since we're comparing numbers, we'd best be comparing the best ones. You already posted my best in Valley 1.0.
Here is my best in Tomb Raider with FXAA. Mind finding out the boost in performance over your 660 SLI?
It is a known phenomenon that two weaker cards in SLI can outperform a single better card. But you do pay in ways other than just financially if you go down that road. My list above should suffice in making my case.
I apologize for not being able to run all those benches right now, because I don't have the applications/games installed right now. And also because just running them once won't give me my best score (learned this from benching Valley 1.0) which would not reflect the actual performance my system can provide. Being a benchmarker yourself, you should be able to understand the situation.
But if you can cite 780 vs 580 SLI numbers from a legitimate source, I'd be glad to see the comparison.
Also, since you insist on considering a much lower difference than what we're seeing between your 660 SLI and my Titan, shouldn't you take into consideration the overclocks OP is running? If its not much (how good is 860/2100 for 580s? I dunno, you tell me.), then the difference would probably be bigger than what you're making it out to be, don't you think? And we both know how monstrously 780s can overclock - its like Bruce Banner and the Hulk.
So I think what it comes down to for the OP is to consider all the benefits of going for the 780 that I mentioned and see if its worth the $450 to him. The boost in performance with a 780 is undeniably there although some might say its a bit low, and not having to deal with all the things I mentioned in the list, including the 1.5GB VRAM limitation, should prove to be the cherry on top of the icing.
