ssd? were talking about pcie 3 here
SATA-III (And USB 3.0) uses PCI-E lanes.
Read in the context of the PCIe 2 VS 3 benchmarks where the speculation was more kit using more lanes MAY cause a bottleneck on a new high end GPU. At which point PCI-E 2.0 may present lower benchmark results. PCIe 3.0 is never going to make the card, in isoltion, faster though.
That will only occur when the bus is bottlenecking the card. It seems unlikely even the new GPUs will bottleneck PCIe 2 unless, perhaps, if you start stacking tonnes of them in multi card configs.

I'm waiting for Kepler and for Nvidia to do 28nm right. Yes Amd have the fastest single GPU card... whoo hoo +10% (at the resolution I use) ... for £500 ... plus quality Amd drivers to boot... No thanks !
Same, I was expecting more than ~10% in BF3 at 1080p.. At least 25%
Im gonna wait for either drivers to mature and price to drop or Kepler.
from what i understand, pcie 3 allows for 16gb/s in each direction
so we know how much these new cards use out of that 16?
dont forget what nvidia did with gf104, its was reworked and tweaked architecture that removed some of the compute capabilities and went superscalar on the architecture.
kepler will be something interesting indeed next year, and guaranteed to take back the single gpu crown once more.
Plus one to that. Can't believe the Nvidia fanboy crap that is being spewed out by some. The 7970 is the faster card, that cannot be denied.
Yes it's performance seems underwhelming in some areas (Dirt 3 for example), but very fast in others (ARMA II). BF3 and Skyrim performance seems inconsistent across review sites.
It remains to be seen how much better performance could get with more mature drivers and unlimited overclocking. It won't be for everyone, but it seems possible that a 7970 could end up beating a 6990 in a number of games when given the full beans with more mature drivers, so long as the memory bandwidth doesn't become a bottleneck (see image below):
I only say more mature drivers could deliver much better performance because this is a completely new architecture, and that's the only reason.
what a bias link to put in, using overclocked card not a stock one
an overclocked 580 can perform 40% better than a stock one so for £500 its far from a bargin tbh
and I have been wanting to change to this new card
bit tech have the performance a lot closer than toms hardware

Its not biased at all as the stock 7970 is in there as well. Never seen a gtx580 that can give 40% extra. The core would have to be running way over 1100 to get 40% extra performance.

Doesn't make a huge amount of difference to be honest.

Its a nice effort from AMD, but even they have changed the arcutechture to something similar to what nvidia use.
I'm sure with some tweaking and improved drivers and cooling the 7970 could see a real improvement. I mean it is a flag ship card so should be the best of it's generation!

I have a 6950 in a 4x slot and it seems to be happily running X-fire with my one in the 16x slot.

Bit tech are using a slower clock speed on the CPU which might be why their results are closer..

Should not give to much of a performance hit running it at 4x to be honest.
Although the VRAM is an issue, it's not worth spending £500 on this card for an extra bit of horsepower when I get 60FPS constantly in every game at max (or near to max) already - with a setup that cost £200.
I was hoping for more, for less
An overclock to 1.3 GHz on the core makes this much more of a beast and it seems that is going to be achievable on the 7970. Right up there with a 6990 and 590 then! Put's the cost in perspective when compared to either of those cards doesn't it. Starting to seem a bargain of a card to me now and even more so when they price drop
Go look at some gtx 580 overclock performance increases
because battlefield 3 needs so much cpu power?
and the benchmarks are not using a 3gb 580 and thats a closer price point tha2 a 1.5gb

I am not looking around for the odd freak card that can achieve this. The norm for a gtx580 overclock and added performance is not gonna be anywhere near 40%. I dont see your problem they are not reviewing a gtx580. They showed oc performance on the card they are reviewing. The gains were nice and in no way were meant to make the gtx580 look bad.
