New Pascal GP104 (GeForce GTX 1070 and 1080) GPU Die Photos Surface

Earlier some photos already leaked, however there are new photos available on mainstream to high-end Pascal GPU under codename GP104. The photos are showing the GP104 GPU would be the successor to the GM204 and thus will replace the GeForce GTX 970/980.



According to the leak the photo shown below is the GP104-200-A1 (GM204 successor) intended for Nvidia's pending high-end products, and it measures roughly 290-300mm². At the right side you can see Samsung GDDR5 chips, earlier already spotted as 1.5V 8Gb 8Gbps (running 8000MHz as effective data-rate) GDDR5. Word on the street is that this 16nm fabbed Pascal architecture based GPU would hold 2560 shader processors.
  

NVIDIA GeForce   Possible
name
Pascal Fab Board Date
GTX Titan X >> TBD GP 100 16nm Reference -> AIB TBD
GTX 980Ti >> GTX 1080 Ti GP 104-400 16nm Reference -> AIB June/July
GTX 980 >> GTX 1080 GP 104-200 16nm Reference -> AIB June
GTX 970 >> GTX 1070 GP 104-150 16nm AIB design June
GTX 960 >> GTX 1060 GP 106 16nm AIB design October
GTX 950 >> GTX 1050 GP 106 16nm AIB design October

The rectangular die of the GP104 was measured at 15.35 mm x 19.18 mm which should house (very speculative) a transistor-count of 7.4~7.9 billion. Interesting to see is that this chip is tied towards Samsung 8-gigabit GDDR5 memory chips. These ICs run an effective speed of 8 GHz (GDDR5 and thus not GDDR5X). At 256-bit you'd be looking at 256 GB/s of bandwidth. The shader processor core count of the GP104 should be closer to 2,560, opposed to the 4,096 indicated from an older report.

If we chart things up (and the chart below ids very speculative) we see the following. BTW the GP104-400 for the Ti might very well become a GP100 based SKU, which would make more sense

Earlier on it was speculated that graphics cards based on these GPUs would be called X70 and X80, the specs do not meet up even slightly though. The new photos are courtesy of Asia region based Chiphell and seem to be originating from an early engineering sample.

Days ago a photo also leaked of what could be the GeForce GTX 1080 cooler.
