Sure my Titans were hideously expensive but at least I knew what kind of performance they offered beforehand and could make an informed decision on whether to buy or not...
I think it's safe to say it's guaranteed to be at minimum 25% faster than 7970.
37% more stream processors
Roughly 25% more bandwidth
37% more TMU
37% more ROPs
Now compared to Titan it has
4% more stream processors
roughly 12% more bandwidth
22% less TMUs
8% less ROPs
So based on how 7970 GE performed against Titan I'd say this is going to be a card that comes in right below Titan performance in most scenarios and even outperforms it in some. While we don't know the price, based on AMD's current pricing structure and vocal reluctance to stay away from $999 single cards (and the 780s $650 price point), it's most likely going to be around $500-$600.
Of course there's also Mantle and AMD making claims that it will "ridicule" the titan with mantle, so expect greater performance in that and Frostbite 3 games. The million dollar question of course is how much faster it will be, If it was going to be a massive increase, I'm sure AMD would have provided benchmarks. But I'd say it'll probably come in around 20% faster than a Titan, otherwise this big focus on Mantle doesn't seem like it would be worth the effort IMO.
Regardless, you can extrapolate that the Titan is 50% faster than the 7970 GE in Battlefield 3, so if the R290X is going to be faster than the Titan, it's going to probably be around 50% faster than the 7970 GE (assuming they both get 20% increases from mantle, and that the R290X is indeed faster than a Titan in BF4).
The real way to look at this scenario isn't about performance. Performance of the R290X can be estimated pretty closely at this point. The real question is whether you think this kind of upgrade is worth the price, which is the same question many people asked when they upgraded from a 680 to 780 (let's forget about Titan here since the 680-780 upgrade path is more akin to the 7970-R290x path).Edited by lajgnd - 9/27/13 at 6:37pm
