Straight out of China comes the latest engineering sample leak, this time from Nvidia. This is allegedly a picture of a second-generation Maxwell prototype, to be released eventually as GeForce GTX 880.
There’s a few things to make note of here, some of which may be due to the prototype nature of this particular model. For instance, there are three PCI-E power connectors on the end (6+6+8 pin), but it’s unlikely that the final product will need so many. The rumoured power input for GeForce GTX 880 Maxwell is 230W. Also, there appears to be an SLI bridge connector at the top, but that could be a diagnostics header. It is possible that Nvidia will continue to use SLI bridges, but it would be odd for them to do so considering AMD has already left them behind with XDMA Crossfire.
The GeForce 880 Maxwell prototype is using sixteen Hynix H5GQ4H24MFR modules, for an ungodly total of 8GB of memory running at 7 GHz, all of which can be used by the processor (unlike dual GPU graphics cards with huge amounts of memory which gets split between the two processors).
Here’s the alleged GM210 GPU die (according to the site), with a date stamp of 1421A1, suggesting that it was manufactured just a few weeks ago. It could actually be a GM204 instead, unless (rumoured) plans have changed significantly.
That’s about all we can glean from these photos, which interestingly have some components obscured from view. If you’re going to leak a photo, why not just post the whole thing? We can’t even guess what might be hiding under those pixels… Maxwell is supposed to have an integrated ARM processor, but wouldn’t that be on the die? That is a rather small die, so maybe the ARM will be sideloaded instead. Only time will tell, I suppose.
We’ll leave you with the latest rumored specs of the GeForce GTX 880 Maxwell.
