Nvidia Geforce “Pascal” GP104 captured on image

In connection with this year’s GPU Technology Conference, Nvidia took the opportunity to unveil the first graphics circuit with the architecture Pascal. It is about the record-breaking circuit GP100 of massive 610 mm², which thanks to manufacturing of 16 nanometers holds no less than 15.3 billion transistors.

Now what is said to be an image of GP104 is leaking to the web. The graphics circuit is expected to be the sequel to the GM204, which is used in the Geforce GTX 970 and GTX 980. The size is estimated at 290-300 mm², down from 398 mm² for GM204 and in the same region as Kepler-based GK104 (294 mm²), which was introduced in the spring of 2012 with the then flagship Gefore GTX 680.

Despite the smaller area, the circuit is believed to house about 7.4-7.9 billion transistors, an assumption that is probably based on GP104 being about half the size of GP100. This can be compared with 5.2 billion for GM204, 3.54 billion for GK104 and 8 billion for GM200, which has a significantly larger circuit area of ​​596 mm². This is explained by the fact that the newcomer is based on 16 nanometers.

In addition to the graphics circuit itself, two of these supposed eight memory circuits, which are provided by Samsung and have the model designation K4G80325FB-HC25, are glimpsed. This reveals that it is about GDDR5 memory with a capacity of 1 GB each running at 8.0 GHz, which would give a theoretical bandwidth of 256 GB / s with a 256-bit memory bus.

The use of GDDR5 differs from previous data to SweClockers, which said that Pascal will use new and faster GDDR5X. However, it is possible that Nvidia has chosen to use GDDR5 in its early copies, but also that graphics cards in different segments will be distinguished by the use of different memory types.

Nvidia’s GP104 graphics circuit is expected to be used in the Geforce GTX 1070 and GTX 1080, which will be unveiled around Computex 2016, which launches on 31 May.
