It's been over a year since the launch of Nvidia's first GTX 700 series graphics cards, so in the usual yearly cycle of releases we should be expecting the launch of Nvidia's next line - the GeForce GTX 800 series - sometime soon.
What could be the first graphics card in that line, the GeForce GTX 880, has allegedly been pictured over on Chinese website GamerSky. At this stage it's hard to verify what this card actually is, especially as a lot of the PCB has been pixelated, but it's certainly not something we've seen before.
In the center of the prototype board we see a new GPU that, according to some digging done by ComputerBase, is a Maxwell-based GM204. The estimated die area is larger than that of GK104, which was the first high-end Kepler GPU, but slightly smaller than GK110.
On the back of the board are eight dual-sided SK Hynix memory modules, totaling an estimated 8 GB of frame buffer. It's expected the card will launch with 4 GB of VRAM, later to be bumped to 8 GB by OEMs as the demand for 4K gaming setups increases.
On the top edge it's also possible to see three PCIe power connectors: two six-pin and one eight-pin. This is likely just a feature included for testing the prototype, as the maximum supported power draw of 375W is significantly higher than Nvidia's current flagship single-GPU cards.
It's not clear when the GTX 880 will launch, but with the engineering samples nearing completion, it shouldn't be too far away.
