We have a few major leaks and rumors to discuss regarding new additions to Nvidia’s Geforce range of cards. There’s nothing further on the new Maxwell architecture (so far), but instead we can discuss the Geforce GTX 790 and the Geforce GTX 880M. Both new cards are expected to be seeing the light of day by some point in February. I’d like to point out that this hasn’t been confirmed by Nvidia as yet, and thus don’t take it as completely accurate.
Remember that Nvidia will be conducting a CES live stream on Sunday, where they promise to be showing off a lot of cool technology. Check out the article here
Geforce GTX 790 Specs:
The GTX 790 is Nvidia’s dual GPU card, and it’s a fairly odd beast. It’s not a dual Titan, or even a dual Gtx 780 or GTX 780 Ti. Instead, we get 2496 Cuda cores x2, 5GB of GDDR5 RAM x2, 320GB/s memory bus and 2 GK110 cores. So if we compare that to the 2304 cuda cores of a Geforce 780, the 2688 of a Titan or 2880 of a Geforce GTX Ti you can see the rather strange number.
That’s a hell of a lot of power, this means that the total count of Cuda Cores for the GTX 790 is a staggering 4992, with 10GB of GDDR5 memory with a 640 bit memory bus.
It’s fairly strange that Nvidia have chosen to release such a powerful card – particularly as we’re expecting to be seeing the new architecture from Nvidia – Maxwell, any time now. It’s possible that some of the cards could even be revealed tomorrow, we know Nvidia are planning a live stream. This news would hint that the very high range cards would not see a simultaneous release. Or that the Maxwell GPU’s won’t have the grunt to out perform the GTX 790. Otherwise what would be the point in releasing it?
Geforce GTX 880M Specs:
There was a recent leak by notebook vendor Clevo, where they detailed a variety of different GPU’s in the GTX 8xx line. They are pretty much what you would expect given the leak, rather than based on the Maxwell architecture, they are instead based on the Keplar GPU’s. They feature faster clock speeds than previously, and the GTX 880M features a rather staggering 8GB GDDR5 Video RAM. Below is a list of the high / medium range cards:
GeForce GTX 880M 8 GB / N15E-GX-A2
GeForce GTX 870M 6 GB / N15P-GT
GeForce GTX 860M 4 GB / N15P-GX
Now the interesting part about these is that they’re MXM chips. This means that not only would they offer SLI, but they could actually be replaced and upgraded, just as you would a typical desktop PC.
The lower range parts however aren’t MXM chips. Instead, they’re as you would expect – soldered directly to the motherboard of the device in question. Their part numbers are listed below:
GeForce GTX 860M 2 GB GDDR5 / N15P-GX
GeForce GTX 850M 2 GB DDR3 / N15P-GT
GeForce GT 840M 2 GB DDR3 / N15S-GT1
Please note that this information should not be treated as official confirmation until Nvidia say so. But it’s look fairly likely that this is indeed accurate.
