Not 1920, not 2560, but 2048 CUDAs are powering the new flagship card from NVIDIA.

GeForce GTX 980 has 16 Streaming Multiprocessors Maxwell (SMM), which give us 2048 CUDA cores in total. For comparison, GTX 970 has only 13 SMMs (1664 CUDAs), so there's a 384 CUDA difference between these two cards.

GeForce GTX 980 is advertised as GK104 replacement, it is much more power efficient and much more powerful than first Kepler processor.

Seems like the GPC structure has changed since GM107 and the full chip does indeed have 4 GPCs. But each of them only has 4 SMMs.

Wow! 175W for a card that is supposedly 10% faster than the 780, that's pretty impressive! I still won't budge from my Ti though!

They are positioning this as a replacement to GK104? I'm confused. Why would they position a GeForce GTX 980 as a replacement to a GeForce GTX 680 (two generations old) or GeForce GTX 760 (two teirs lower from the last generation)?

I know it is a mid range chip that makes up the GeForce GTX 980, but it's comparing that specific GPU by name to an earlier chip. It'd make sense for the new chip to replace the older one internally to nVidia, but the GeForce GTX 980 being positioned as a replacement to either the GeForce GTX 680 or GeForce GTX 760 makes little sense to me. Bad wording of comparison on the article's behalf, or... am I missing something? I thought the GeForce GTX 980 was replacing the GeForce GTX 780, regardless of the chip either uses?

More powerful cores?
Basically, yes. It's a new architecture.

They're getting revealed during the livestream that starts on the 18th and goes on for 24 hours afaik.

+ as we can see from the change in SMMs per GPC there have been some relatively big changed to maxwell even after that slide was released with GM107 and 750Ti.

The cards that are launching this week are 2nd generation maxwell.

Great to see some concrete evidence finally. Getting excited for the launch even though I have no plans to purchase. I just love gpu launches for some reason.

So, in simple terms - is it much better than 700 series and is well worth the price? Or is it marginal, like 10%, increase in performance vs almost 50% increase in price (local shops do that where I live)? At least from technology PoW.

Got it! Pictures always do the trick

If the 750 Ti is anything to go by, these 970's and 980's should be able to overclock very well.

So I am guessing GM110 or whatever will be big die Maxwell will be the next generation of Maxwell GPUs? Not in the GTX9xx series unless they release a 980Ti? Its more what I am waiting for.

A small, probably around a 10% increase over the 780Ti for the 980 and supposedly a good price. Retailers can always gouge though.

GM200. Taped out a few months after GM204. So it shouldn't be too far behind. Likely H1 2015. And yeah I'm waiting for that as well.

Im still not convinced its time for me to sell my 670s, although I would like to try a new GPU.

Just cannot fathom how this gtx 980 will be anything reasonably priced...Im guessing it will be at least £400 which is far too much.

My thoughts exactly. Unless shipments are coming in mid week. But who knows.

Now that makes more sense as I was saying in another [of the gazillions that exist by now] thread. 1920 Cores was too low and was going to eat into the additional overclock headroom in order to match and beat the GTX 780 Ti.

On the other hand, that first picture seems fake.

"The World's Most Advanced Graphic Card" ?

It should be "Graphics".

Edit: ok, I was enlightened that while this picture is indeed not properly written, the original source is at fault, not VC, so it isn't fake.
