7950CF vs 770SLI question

Pavel Pokidaylo · Jul 12, 2013

How does a 7950CF setup stack up against a 770 SLI setup.

And would adding a second 7950 double my performance in "Most" games?

Random_Tactics · Jul 12, 2013

The 770s would definetly beat the Radeons....

ksham · Jul 12, 2013

I would say the GTX 770 SLI because it does not exhibit any of the CrossFireX issues at this time. And no, you will not get double performance for either the CrossFireX setup or the SLI setup.

To your 2nd question: No, performance wouldnt be doubeld; I would say +80%, but thats just a guess

sam_p_lay · Jul 12, 2013

It will range from 0% to 100%. Seriously! On average, 70-80% can be expected. But even some of the latest games show little to no benefit. Ksham is right about SLI working better, but you're best off getting a single GTX770 and seeing how you go with that. Then if you really need more performance, add a second. Remember prices are only going to let lower as time goes by.

Thanks for the replys guys. To elaborate, I bought as sapphire 7950 two weeks prior to the release of the 700 series. If the 700 series was out when I bought the 7950 I might have gotten a 760 or 770 instead. I've been told the 770 is faster but the 7950 is not far behind. I'm happy with the 7950 for the most part. I can play most games at max settings although I have to turn down shadows for some reason (maybe CPU).
FarCry 3 however doesn't run as well as the other games.

Anyway I think I'd be happy with even getting an 80% boost from adding a second card. I want to be able to slap on any game and max the settings and be at 60fps. I don't want to have to keep dialing down settings. Would adding another 7950 let me do that? Thanks again for the replies.

I was too anxious to get a new card already and did not wait for the 700 series lol. But the 7950 was 100 bucks cheaper and came with 4 games.

Random_Tactics · Jul 12, 2013

Dont worry, the 7950 is a good pick! You should go along with it as long as you are happy, then get a second one.
Is it a 7950GHZ?

Neospiral · Jul 12, 2013

Even if the 7950's had perfect SLI scaling and no microstutter, the two 770's will still perform better since the individual cards wipe the floor with the 7950. Go with the SLI 770's. Really no contest.

Pavel Pokidaylo · Jul 12, 2013

It's the sapphire 7950 flex edition with boost. Don't think it's Ghz edition.

Random_Tactics · Jul 12, 2013

But he has already bought the 7950...

ksham · Jul 12, 2013

Yes; if you are interested in the AMD Never Settle Bundle, then the HD 7950 is a great buy. I would recommend the Sapphire Dual-X Radeon HD 7950. Do note that the Vapor-X edition of the HD 7950 is voltage locked. So that may not be preferred for you.

Also, @Random_Tactics, what is a HD 7950 GHz?

Pavel Pokidaylo · Jul 12, 2013

I know the 770 is a better card but from all the benchmarks I've looked at the 7950 was not far behind. And when the 7950 was overclocked it was getting the same FPS as the 770. The one game that I've seen the 770 really run away was FarCry 3 the 770 beat the 7950 by about 15fps.

Random_Tactics · Jul 12, 2013

ksham :

Sorry, my mistake; Was talking about the Boost-version...

Pavel Pokidaylo · Jul 12, 2013

Yep I've already got the 7950. And it has the Dual-X cooler on it. I believe it is also voltage locked but I'm a noob and don't want to mess with the voltage. I can raise the Core clock to 1100 and power to 20% and get a 10fps boost.

Pavel Pokidaylo · Jul 12, 2013

Apologies for not making the initial post more clear. Sorry

Pavel Pokidaylo · Jul 12, 2013

It boils down to the fact that I'd have to sell the 7950 in order to get the 770. Basically my question is this... Will I be able to max out all games and stay at 55-60fps with 2 7950s or do I need 2 770s to be able to achieve this.

ksham · Jul 12, 2013

You should be able to play most games at that FPS @1080p on a HD 7950 CrossFireX as long as you don't run into issues with them.

Pavel Pokidaylo · Jul 12, 2013

Thanks man. That's what I though. I mean I already get 60fps in games like Crysis3 and Bioshock as long as I don't crank up the shadows.
I figure a second 7950 would give me that extra juice I need and then some.

sam_p_lay · Jul 12, 2013

Depends on res. Assuming 1080p though, you'd want SLI GTX770s to be maintaining 55-60fps in Crysis 3.

Pavel Pokidaylo · Jul 12, 2013

Without the shadows my one 7950 gets me 55-60fps in Crysis 3. But again that's without the shadows turned up.

Pavel Pokidaylo · Jul 12, 2013

Honestly FarCry 3 seems to be way more taxing on my card than Crysis 3. Don't know why.

sam_p_lay · Jul 12, 2013

That is a very demanding game too. What settings and res do you play at? And anti-aliasing etc? Tom's benchmarked the 7950 Boost averaging 36fps in Crysis 3 at 1080p, very high and 2x SMAA. For Far Cry 3 ultra 1080p and 4x MSAA, the 7950 Boost averaged 33fps.

Pavel Pokidaylo · Jul 12, 2013

Crysis 3 I can play with all settings on max except shadows and FXAA or 2XSMAA and get 55-60 fps. The only place I saw the fps drop was on the last boss all the way at the end of the fight for like 5 seconds . FarCry 3 is weird. My fps varies way too much but I play it with 2XSMAA because it doesn't really make a difference if its off or the 2Xsmaa I still get the same fps. As for the visual settings there are areas where I'll drop down to the low 30s with max settings and if I set them all to low I'll be at around 45. Then there are areas where I can have all settings maxed and be at 60fps (mostly inside caves and houses).
