NVIDIA GeForce GTX 780 Specification

GPU: GK2xx
Base Clock: 1100 MHz
Boost Clock: 1150 MHz
Memory Clock: 1625 MHz (6500 MHz effective)
Memory type: 3GB GDDR5
Memory Interface: 384-bit

According to Chip.de, the GeForce GTX 780, which would supposedly use this processor, may feature 2304 CUDA cores. The site also reveals that the card would use 3GB GDDR5 memory across a 384-bit interface. Nevertheless, our sources are less enthusiastic about this card. From what we know, it would have 1920 CUDA cores (2110 tops), 160 TMUs and 48 ROPs. Needless to say, probably the most certain information right now is the 384-bit interface. The site also mentions the exact clock speeds, but it seems that these are pure speculation, since NVIDIA does not usually launch their cards with such round clock numbers. Anyway, from what has been said so far, the GPU would be clocked at 1100/1150 MHz (for base and boost respectively), and the effective memory clock is 6500 MHz.

These specs suggest that the memory bandwidth would increase from 192 GB/s to 312 GB/s (that’s 62% increase). The texture fill-rate would be around 170.6 GT/s (32% increase) and pixel fill-rate 52.8 GP/s (64% increase)
 
Coming in February/March? Seems a little early but I'm still curious about what these will do. Hopefully they'll get back in the game this time around.

What 680 lacks is memory bandwidth.Switching to 384 bit will fix this and from the added features of GK110 it will definitely beat AMD.From last I heard the next gen from AMD was looking like ~20% faster than 7970.
 
No one knows exactly how it will perform right now, except that it will hopefully be a good increase over this generation. If it can't trounce the 7*** series, then something is wrong. AMD's next generation will hopefully give them some motivation to perform though.
 
So now we are going to have a rumor battle? This thread is off to a productive start.

I heard that the GTX 890 was gonna be a 3 gpu monster that doubled as a CPU too and is going to decimate Intel and Amd at the same time.
 
nVidia released GK110 specs months ago. AMD has had a pretty accurate performance target for a long time. We'll have to wait and see what they do with that info.

To be fair it is a rumor after all 😀 I'd be down for that beast you're speaking of. Maybe it will be large enough to double as a stove as well.
 
Since bitcoin is looking to become unprofitable for me come this spring, I'm more seriously considering nvidia again. If true, a 384-bit bus and 48 ROPs are great choices in my eyes for high-resolution gaming, but I'm still waiting to hear word on whether they're going to lock down overvolting again. It may not matter because AMD seems to be doing much of the same with later revisions of the 7xxx series, but we'll see.
 
Actually, Maxwell will feature ARM cores.

Maxwell will be Nvidia's first graphics processing units to contain project Denver 64-bit ARM-compatible general-purpose core, which means that Maxwell will be able to boot operating systems themselves.

Sure it hurt Intel and AMD. Especially AMD. 😀

Is AMD locking voltage control on their reference cards? Custom cards can be voltage locked but it's not AMD's choice and I didn't hear that AMD forbid software voltage control like NV. It is hilarious, because there is an 680 that can change voltage without any modification but the vendor had to resort to outmaneuvering that asinine nV directive by doing it by hardware. What a regress...

I don't think AMD made any decree, but they have left board designs up to partners in the past. Hopefully reference models stay as robust as they've always been, but I was just hypothesizing and I certainly don't hope AMD heads in that direction. I would never waste my money on a $500 card that doesn't have overvolting capabilties unless there were no other options out there. Even then I'd probably grab the card that the guys at XtremeSystems or somewhere figured out a solder mod for and do that.

In the end any new part from either company will be competing against my 7970 @ 1.35GHz for my dollar. I wouldn't consider a card unless it was at least 25% faster at stock, so we're talking close to GTX 690 performance (which is about 33% faster than what I currently have), and then some ample overclocking room on top of that. While I'm optimistic about what both companies can put out, that's a high bar to reach without a die shrink. We'll see. :thumbsup:
 
If I can't overclock I won't buy it, if the voltages are locked or non existent chances are I won't buy it. If the build quality is meh or less I surely will not buy it.

I do not think either company will get particularly close to matching the gtx690/hd7990 performance with a single gpu on 28nm.
