NVIDIA GeForce GTX 880 Detailed
NVIDIA's next-generation GeForce GTX 880 graphics card is shaping up to be a true successor to the GTX 680. According to a Tyden.cz report, GTX 880 will be based on NVIDIA's GM204 silicon, which ranks within its product stack in the same way GK104 does to the GeForce "Kepler" family. It won't be the biggest chip based on the "Maxwell" architecture, but will have what it takes to outperform even the GK110, again, in the same way GK104 outperforms GF110. The DirectX 12-ready chip will feature an SMM (streaming multiprocessor Maxwell) SIMD design that's identical to that of the GeForce GTX 750 Ti, only there are more SMMs, spread across multiple graphics processing clusters (GPCs), probably cushioned by a large slab of cache.
This is what the GTX 880 is shaping up to be.

ready for 4K Games ready for O.C i think 256bit not enough for high resolutions
instead 7.40 Ghz memory speed
AMD Pirate Islands : R9 300 Series Alleged Specifications Detailed, Flagship Cores Bermuda XTX, Treasure Island XTX and Fiji XTX
Anyway, I thing 32 ROPs is pretty low for a hi end card today with 4K in mind, or am I wrong? 256bit already mentioned.
Maybe it is happening what I am afraid of. Hi end names and prices on mid range products.
That's why I was shouting that Titan was and is bad news for us gamers/desktop users no matter who's company fan you are and 295X2 is in fact a ridiculously overpriced card justified partly thanks to Titan Z's price. And it doesn't matter if you rush to defend the semi custom nature of Titan. As gamers WE DO NOT CARE FOR THE PROFESSIONAL FEATURES OF THE CARD.
Who ever was defending Titan, as a good Nvidia fanboy, gets as a present a card with 32 ROPs instead of 48 and 256bits data bus instead of at least 384bits. Congrats.
NV stated they'd be doing a tick-tock setup like Intel. Kepler was a nice advancement but it was still the tock to Fermi. It isn't super different. Now we're going on the next tick, which is Maxwell.
Interested to see if NV gets it right again like they did with the 400s. The 750 is really mediocre and its a GM chip. Will be keeping a close eye and hopefully new employment to pay for it. Unless of course, AMD finally gets everything right.
Should be interesting to see how big the die gets. 4224 cores are a 50% increase over Hawaii for a less than 30% smaller node transition.
Both of these estimations (Pirate Islands and GM204) look more like wish lists, unless the timeframe is further out to allow for 20nm/16nmFF node usage.
Here the comparison chart and it looks like going to cost just as much as a 780 TI. Have to wonder how much the big chip will cost then :(
The cost per wafer for 20nm BEOL+ 16nm FEOL (FinFET) is rumoured to be around $6000-6500 per- a sizeable cost increase over the existing 28nm process (< $4K) + costs for masks. If the Pirate Islands info from WCCF :rolleyes: is ballpark then there probably wont be much difference in die size between AMD and Nvidia at the high end. A quick and dirty calculation says that AMD's chip (for a 50% core increase) would be ~460-470mm², while Nvidia's would probably decrease from its current flagship (551mm²) (GM204 not GM200 if it eventuates) since the core count is only increasing by 11% and uncore would decrease in relation to GK110 (less die space needed for memory controllers, I/O) unless Nvidia decide to beef up the SFU's to increase FP64 or dramatically increase cache.
Now GTX 880 already rumoured..Jezzz :(
And the "leaked" specs is not that impressive compared to the "leaked" from AMD

I expected some leaked nVidia's slides when I read the title "NVIDIA GeForce GTX 880 Detailed" (which has no question mark). What a mislead article.
860Ti with 1 x 6pin and I'm sold .
The silly season is upon us. People are itching to hear about something new after a relative ( two-and-a-bit years) eternity on 28nm, so the semi-pro guessers lay down the estimates and the forums go wild. That Czech site will probably get more hits in the next 24 hours than they normally get in 6 months. Ka-Ching!
GTX880 - 16000 CZK (583 Euros / 807 Dollars)
GTX780 Ti - 16100 CZK (586 Euros/ 881 Dollars)
The plan is same as always, to milk the consumers. Nvidia will sell you cut down GTX 880 first with disabled ROPS,TMUs CUDA cores etc etc, then AMD will release something, as good or better, then Nvidia will unlock some features of same silicon and call it 880 Ti so consumers need to spend hundreds on a new card.
There is no "better" graphics card company, they are both in on it, everything is pre-planned, Nvidia knows exactly what AMD is doing and AMD knows exactly what Nvidia is doing.
