well that surely sounds far more interesting than both titan-z and 295x2.

256-bit???

I don't understand the whole 256bit, 384bit and 512mb bit thing, just a number to me that is meaningless and has no impact on anything, it doesn't seem to matter in games at all. It is like ram latency and speed, all meaningless to me, none of it impacts game performance, I've tried loads of different types of ram and the FPS is always the same. Same with bit rate, has no impact on games.

agreed on the system ram part. From what ive read and tried myself, system ram and game performance seems to be based on how much you have more often than if its 'performance' ram or not.
I didnt want to be the first to post the - another 680 - comment. Glad im not alone on that thought.
As for the 256-bit, Its almost the same as slapping stupid amounts of ram on low to mid-range cards. Why!

Boring. I'll wait for a 980Ti something instead.

What's this...nVidia turning 20nm wafers into scratched records?

So this is definitely not aimed for 4K gaming then. They'd need to increase the ROP count a lot and that memory bandwidth does not help. Assuming that those numbers are correct.

I dunno I'm using a 750ti now that is 128bit and it performs like my 670 did, I don't see it being a bottleneck at all, this card is just amazing. I'm running a triple monitor setup at 5000something x 1080p and getting 60FPS while maxing out Assetto Corsa lol. Everyone on the forums talking about a 780ti for it.... well I spent £106 and am doing it just fine on this and it overclocks like mad with no external power connector.
I'm never spending loads on a GPU again, seems to me the CPU is the major bottleneck right now as games for some reason love maxing 1-2 cores and ignoring the rest. The new Nvidia beta drivers have increased my FPS massively too, I'm getting better FPS in Dayz now than I ever did with my 670SLI setup.
SLI doesn't work, just like Crossfire, it isn't worth it, I've tried both and like 2 games I've ever played have made use out of it.

These are not final but... I don't know... I think I expected more for this 880 (on the paper).
Besides CUDA cores, most of the numbers are similar/lower than 780. The memory bandwidth looks kinda narrow which is a shame because I thought about this 880 as an upgrade of my 680 suffering from its own limited memory bandwidth. But with the efficiency of the new chip, who knows... And the price also 🙂
Wait & See

I'm sure there's lots of other articles out there saying the same thing. Don't fret about the lower memory bandwidth on Maxwell cards.
Maxwell works very efficiently with what we would consider a narrow memory bandwidth. I remember reading this in an article outlining the technology behind Maxwell and the 750ti when it launched. Effectively, it uses the memory bandwidth so efficiently that it's almost a factor of two, so the 238GB/s memory bandwidth figure would effectively be more like 400GB/s when making a comparison to Kepler architecture that we know so well. Part of this efficiency of memory bandwidth use is based on the Maxwell having a large L2 cache.
EDIT: Just found a quote from a 750ti Maxwell article that indicates what I'm talking about:
"The number of ROPs remains unchanged, while the size of the L2 cache has increased by 8X. The increase in L2 cache helps the card become less dependent on memory for bandwidth and makes memory less of an issue."

If that price is what Nvidia are going to charge for GPU's now especially when it's a GTX680 like product they can f*** right off, it's basically the same as a 780Ti!
