Looks like there might be 3 released by October under GTX 800 naming and GTX 990 in early 2015:

http://www.lazygamer...formance-jumps/

Im curious if it will be 16, 20 or 28nm. Rumors so far say GTX 990 will be 16nm and skipping 20nm all together. Ive seen rumors saying that 20nm is having fab issues so 28nm will be for the GTX 800 series. If they are having issues with 20nm, not sure how they will do 16nm...

Naturally, none of the above matters if pricing is out of whack, but the good news is that it isn't. The GTX 980 carries an MSRP of $549, while the GTX 970 will go across the counter for $329. This bumps the GTX 760 down to $219.

----------

 

looks like just launched, looking at the benchmarks :0

 

Edit:

 

Wow the price/performance is very nice.  Looks like a great launch.  The 970 looks to be as strong as the 290x in most things.

I'm more impressed with the power consumption! I was hopeful that these wouldn't use to much considering the Maxwell based GTX 750's sipped power, and things worked out pretty well :-)

You and me both. My computer hasn't booted in over a year. I want to fix it but might build myself a new system instead.

impressive performance per watt without a die srink

be nice if they implemented gpu power down at idle like amd has so they use less power at idle in sli and if the monitor is asleep

 

the 256bit memory interface is less restrictive than i thought it doesnt seem to take any more of a hit than the gtx780ti at high res

both still lose some ground at 4k to the 512bit 290

 

die shrink of this with 6g 384bit memory and a bit bigger core will be a impressive bit of kit

I have to admit that nVidia really pulled a rabbit out of the hat and brought a sledgehammer to the Radeons. However, it really didn't disguise the fact that the GTX 780 should have been retired long ago. That's how I see it. If this was the game changer nVidia wanted, then it should have been brought in when R9 290/290X came out. But as I see it, AMD got the initial jump and we'll see what Red does to respond.

I'll probably buy a GTX 970 for the fun of it... Seems as fast as the 290x. The boost on some of these are crazy high if thermals allow.

gtx980 overclocked to 1.5ghz boost is a tempting thing at us prices ~$550us but im going to wait it out

die shrink? I think you mean node shrink, cause the die is smaller than GK110

 

Like Tonga 256bit is reasonable now thanks to compression magics

 

Yeah, GM210 will smack AMD around hard. Even an upscaled Tonga won't be able to compete I'd think.

 

 

Well played Nvidia, very impressive. Shame they decided to go sideways performance wise but they now definitely have thermal and power headroom for an even bigger Maxwell chip.

The question has been raised by a few whether or not the GTX 980 uses all available resources on its die. I just noticed a new product on PC Case Gear, the Leadtek Quadro K5200 8GB Workstation Card, which has 2304 CUDA cores, a 256-bit memory bus, and a 150W TDP, which is very close to the specs of the GTX 980, which is similar except for having 256 less CUDA cores, at 2048 total. This does make me wonder if there will be a GTX 980 Ti based off the same chip if AMD brings something more competitive than an R9 290X

As far as I'm aware, the 980 uses all resources on it's die, but it is a dimensionally smaller die than the 780ti, much in the same way as GTX 680 was a smaller die.

 

So there is the possibility/probability of them releasing a full sized GM210 chip down the track.

Im trying to locate the MSI version since Ive been doing research and it appears to have the best power delivery of the GTX 970's with 6+2 design.  Supposedly, the EVGA version is one of the worst with 4+2 design and has coil whine.  Also, some of the 970's appear to have different connections for monitor and to hook up the power to the card.

i dont think its misaligned as the core looks to be directly over the two main heapipes

they just tossed that one in for good measure i think which may knock a few c of the max temp

Still seems a bit weird to me. Why not use all the available surface area for better cooling? Otherwise it's just a waste

The heatpipe not touching gpu core while not ideal, still would function, heat would still get to it via the aluminium block the pipes are seated in.

 

Remember the days when heatpipes first came out and the pipes weren't directly touching CPU cores? They still worked, just not as efficently as direct contact (which came later).

 

Wouldn't call it a waste, but it's not the most efficient design.

Maybe they re-used a cooler design from an OEM or earlier product, and called it good enough.

 

I'd be annoyed if I bought one and found that out though, it's a missed opportunity.
