Pretty much what was expected I would say. Interesting to see a Ghz 7970 pretty much matches a 780. I would expect the 780 to improve performance though once Nvidia optimise drivers for BF4.
Still, looks like AMD are winning on the Battlefield

Amd's claim of a r9 290x smoking Titan in this with mantle could well be true as it already has a nice lead. This is what we saw with bf3 but the other way around until Amd brought out some nice drivers.

But GTX780 SLi smokes 7970 Crossfire?
hmmm
hmmm

I think they missed a trick not benching the different CPUs on multi-GPU configs at 1080 and 1440 res.

Looking at the scaling of the gtx 660 compared with the 270x it seems Nvidia have better scaling atm.

LT's bullet points sumarry
1. This should have gone in the BF4 benchmark thread.
2. 290x 25%+ faster than a titan. Spankage. This is before Mantle. The ridicule a titan statement may well ring true once mantle arrives.
3. SLI scaling better than Crossfire so far. This surprised me a lot.
4. 7970ghz as fast as a 780, nice.
5. Not using the latest AMD drivers. Benefit of the doubt though as they probably wrote the review before they got released.
6. Crossfire frame pacing providing better frame times than the 690. Impressive! 290X frame times also the best, closely followed by 7970 crossfire. Big result here for AMD.
7. Single player is crap for cpu usage benchmarks.
13% faster. Not bad considering in their 7970 crossfire bench the 7970 only have 64% scaling. Something looks up there to me. 270X crossfire below that scales to 77%.

Yeah sorry forgot to say make sure you lower you headphones down. I paid that price heavily in 7.1.

Better scaling. 7970 CF might well close that gap with improved drivers.
780 SLI is getting nearly 100% (impressive)
7970 CF is getting around 75%

2 more results there seeming showing that 2GB is enough for 2560x1600 but more importantly, showing how taxing this game is at that resolution. Never mind owning the top card, you will need a minimum of 2 of them if you want to play this at 1600P or above...All this talk of the memory bus is valid and I don't dispute it but seeing how everything is having a torrid time, it looks like we need 20nm sooner, rather than later

Single player benchmarks both of them Greg. Read the benchmarks. Multiplayer only, come on. 
Soldato
It's surprised me a lot. What's with that? I've seen that SLi has been great for me but assumed AMD would be better given the development etc.
New drivers to rectify this? Or are they leaving it to Mantle?
Soldato
Nvidia seem to be doing better in multiplayer, from looking around a few sites. AMD FX CPUs seem to be suffering in mp too.
Like BF3, single player doesn't really tell the full story. regardless of other anomalies that pretty much every benchmark/review brings up

Sorry Matt, I didn't realise you had set the rules to posting
I can't find anymore results apart from that sweclockers one and as the game isn't released world wide yet, I will take what I can get to inform people who are interested.
to me, it looks like a minimum of a 690 is needed if you want to play at 1600P or at least two overclocked 7950's.
Soldato
BF4 is SUPER SMOOTH for me even with 3 cards, a credit to AMD's hard work I say.

780 getting 87% scaling.
Not sure. According to gamegpu 7970 ghz got 31fps and 7990 got 56fps. 7990 is 100mhz slower on the core for both gpu's than a 7970 ghz. Using those scores that suggests 80% scaling. Actually it would be higher than that if you had 2x7970 instead of the slower 7990.
Ok probably not the best example. Lets look at sweclockers. 280X -44fps vs 280X crossfire 81fps = 84% scaling. Still worse than SLI but much better than 64%.
As i said something looks up with the TechSpot bench regarding crossfire scaling. Gremlin in the system, driver bug? Who knows. When you look at their 270X crossfire scaling of 77% at 1600P, slower cards scaling dramatically better?

As I said, I can't even think of an abstract theory to back up that multi-monitor thing. Anyway your VRAM hitch was in Skyrim wasn't it? I was talking specifically about BF3/4.
It's always been bandwidth limited to a degree above 1080p. I don't think I ever denied that but I can remember reading some stuff where people were saying it wasn't bandwidth limited. My triple screen tests illustrated that with alarming levels of performance drops on the 680s compared to 7950s (which aren't even in the same tier). It would have been even more damning against overclocked 7970s.
So having seen how the bandwidth could affect performance just by increasing the resolution I have always been of the opinion that the bandwidth cripples performance at that resolution. Especially when applying MSAA.
