Nvidia’s Pascal GP104 GPU dies have been pictured for the very first time. They’re the same chips which are expected to be used for the upcoming arrivals of the GeForce GTX 1070 and GeForce GTX 1080.
GP104 will come in two flavours, GP104-200 and GPU 104-400, for the GTX 1070 and GTX 1080 respectively. The GP104-200 die is a cut down version of the GP104-400, featuring a weaker configuration than the full-fat GTX 1080 chip.
The shots of the GPU-400 have interestingly not come from a reference board but in fact are from what looks to be a custom MSI GTX 1080 Gaming 8GB PCB. This also tells us that Pascal is extremely far along in production; the chips are in partner’s hands and will presumably be ready for sale soon.
As per other leaks relating to Nvidia’s upcoming GTX 1000-series graphics card families, it’s also confirmation that the first wave will utilise Micron’s GDDR5X memory chips. These are capable of potentially double the bandwidth of their GDDR5 counterparts, but it does mean we won’t be getting our hands on HBM2 just yet. On the GTX 1080 we can see there is going to be 8GB GDDR5X.
Aside from this it also demonstrates how the adoption of the 16nm fabrication process has led to an even smaller GPU die than that of Maxwell, thanks to increased performance and power efficiency compared to the previous 28nm generations.
From the looks of things to launch of Pascal is imminent. While June has previously been the mooted month, at this stage we wouldn't be surprised to see Nvidia push it out early with a full reveal in May.
